Is It Arthritis Of The Thumb Joint?

Is It Arthritis of the Thumb Joint?

Sore ThumbI was pondering what to write about in this month’s newsletter and then I had three clients come in, all suffering from the same problem.  That made up my mind. The topic this month is thumb pain.

Several years ago, when I was still in New York, I had a regular client come in and tell me she had just been told she had arthritis in her thumb joint. I asked how she knew that, and she showed me her hand.  Her thumb was bent all the way in toward her palm and when she tried to bring her hand flat, the joint was painful, preventing her thumb from moving.

She had been given medications for the arthritis, but when she checked it out on the internet, the potential side-effects scared her so much she decided to just suffer with the arthritis.

But it wasn’t arthritis at all. The pain she was experiencing was caused by a tight muscle. I taught her the self-treatment I’m going to show you, and the results were fantastic!

Why a Tight Muscle Causes the Symptoms of Arthritis of the Thumb Joint

We use our thumbs uncountable times every day. It is impossible to even consider how many times we have used our thumb muscles over the course of our lives, but we never think about the muscles that enable us to do that movement. Yet, think of what life would be like if you lost your ability to use your thumb.Thumb Muscle

 

Your thumb muscle, called Opponens Pollicis, originates on the ligament that forms the bridge to your carpal tunnel. (More about carpal tunnel syndrome in a future newsletter) It inserts into the joint that is at the base of your thumb.  It forms the bulge at the base of your thumb, right where the thumb of the right hand, shown on the graphic on the left, is pressing into the left hand.

For example, do the movement shown above, pressing your right thumb into the thick muscle at the base of your thumb.  Then move your left thumb in toward the palm of your hand.  You’ll feel the muscle contract.

As the muscle is repetitively strained it shortens.  The problem is, as it’s shortening it is pulling on the bridge to the carpal tunnel and moving your thumb in toward your palm. When it gets tight, if you try to bring your thumb out it will pull at the joint.  It’s like pulling your hair and then your scalp hurts.

The good news is it’s simple to release the tension in the muscle fibers, it just takes a long time to get it to fully release.

Treatment For A Painful Thumb

It’s simple to treat your Opponens Pollicis muscle.

Treatment 1 For Sore Thumb

 

Place your opposite elbow directly onto the muscle. Wrap your fingers around your elbow to stabilize it so it won’t slide off the muscle.

 

Press deeply into the muscle and either stay still or move very slightly back and forth to lengthen the muscle fibers.

 

Or you can…

 

Place your bent middle finger directly into the muscle and wrap your hand around your hand to stabilize so your Treatment 2 For Sore Thumb Muscleknuckle won’t keep sliding off the muscle.

Hold the pressure for about 30 seconds and then move ¼” along them muscle to a new spot.

I developed this technique when I had carpal tunnel syndrome. It took me hours of self-treatment to get the muscle to final relax and not be painful.  That’s when you know you have finally released the tension and the strain is removed from the bridge to your carpal tunnel (flexor retinaculum).

Even if you don’t have the symptoms of carpal tunnel syndrome, doing this technique will make your hand feel so much better, more flexible, and light.

Which Diets Are Best In 2022?

Which Diet Should You Choose?

Author: Dr. Stephen Chaney

Emoticon-BadMany of you started 2022 with goals of losing weight and/or improving your health. In many cases, that involved choosing a new diet. That was only a month ago, but it probably feels like an eternity.

For many of you the “bloom” has gone off the new diet you started so enthusiastically in January.

  • Perhaps the diet isn’t working as well as advertised…
  • Perhaps the diet is too restrictive. You are finding it hard to stick with…
  • Perhaps you are always hungry or constantly fighting food cravings…
  • Perhaps you are starting to wonder whether there is a better diet than the one you chose in January…
  • Perhaps you are wondering whether the diet you chose is the wrong one for you…

If you are rethinking your diet, you might want to know which diets the experts recommend. Unfortunately, that’s not as easy as it sounds. The diet world has become just as divided as the political world.

Fortunately, you have an impartial resource. Each year US News & World Report invites a panel of experts with different points of view to evaluate popular diets. They then combine the input from all the experts into rankings of the diets in various categories.

If you are still searching for your ideal diet, I will summarize the US News & World Report’s “Best Diets In 2022”. For the full report, click on this link.

How Was This Report Created?

Expert PanelUS News & World Report recruited panel of 27 nationally recognized experts in diet, nutrition, obesity, food psychology, diabetes, and heart disease to review the 40 most popular diets.  The panel is not the same each year. Some experts are rotated off the panel, and others are added. The experts rate each diet in seven categories:

  • How easy it is to follow.
  • Its ability to produce short-term weight loss.
  • Its ability to produce long-term weight loss.
  • its nutritional completeness.
  • Its safety.
  • Its potential for preventing and managing diabetes.

 

  • Its potential for preventing and managing heart disease.

They converted the experts’ ratings to scores 5 (highest) to 1 (lowest). They then used these scores to construct nine sets of Best Diets rankings:

  • Best Diets Overall combines panelists’ ratings in all seven categories. However, all categories were not equally weighted. Short-term and long-term weight loss were combined, with long-term ratings getting twice the weight. Why? A diet’s true test is whether it can be sustained for years. And safety was double counted because no diet should be dangerous.
  • Best Commercial Diets uses the same approach to rank 15 structured diet programs that require a participation fee or promote the use of branded food or nutritional products.
  • Best Weight-Loss Diets was generated by combining short-term and long-term weight-loss ratings, weighting both equally. Some dieters want to drop pounds fast, while others, looking years ahead, are aiming for slow and steady. Equal weighting accepts both goals as worthy.
  • Best Diabetes Diets is based on averaged diabetes ratings.
  • Best Heart-Healthy Diets uses averaged heart-health ratings.
  • Best Diets for Healthy Eating combines nutritional completeness and safety ratings, giving twice the weight to safety. A healthy diet should provide sufficient calories and not fall seriously short on important nutrients or entire food groups.
  • Easiest Diets to Follow represents panelists’ averaged judgments about each diet’s taste appeal, ease of initial adjustment, ability to keep dieters from feeling hungry and imposition of special requirements.
  • Best Plant-Based Diets uses the same approach as Best Diets Overall to rank 12 plans that emphasize minimally processed foods from plants.
  • Best Fast Weight-Loss Diets is based on short-term weight-loss ratings.

Which Diets Are Best In 2022?

Are you ready? If this were an awards program I would be saying “Envelop please” and would open the envelop slowly to build suspense.

However, I am not going to do that. Here are the top 5 and bottom 5 diets in each category (If you would like to see where your favorite diet ranked, click on this link). [Note: I excluded commercial diets from this review.]

Best Diets Overall 

The Top 5:

Which Diets Are Best For Rapid Weight Loss?

Happy woman on scaleThere are 3 take-home lessons from the rapid weight loss category:

1) If you are looking for rapid weight loss, any whole food restrictive diet will do. The top 5 diets are very different. For example, the keto and vegan diets are polar opposites, yet they both are in the top 5 for rapid weight loss.

  • The Atkins and keto diets are meat heavy, low carb diets. They restrict fruits, some vegetables, grains, and most legumes.
  • The Biggest Loser diet relies on restrictive meal plan and exercise programs.
  • The restrictions of the raw food diet are obvious.
  • The vegan diet is a very low-fat diet that eliminates meat, dairy, eggs, and animal fats.
  • I did not include commercial diets that rated high on this list, but they are all restrictive in one way or another.

2) We should ask what happens when we get tired of restrictive diets and add back some of your favorite foods.

  • If you lose weight on a vegan diet and add back some of your favorite foods, you might end up with a semi-vegetarian diet. This is a healthy diet that can help you maintain your weight loss.
  • If you lose weight on the Atkins or keto diets and add back some of your favorite foods, you end up with the typical American diet – one that is high in both fat and carbs. This is not a recipe for long-term success.

3) Don’t pay too much attention to the bottom 5 diets. None of them were designed with weight loss in mind.

Which Diet Should You Choose?

Food ChoicesWith rapid weight loss out of the way, let’s get back to the question, “Which Diet Should You Choose?” My recommendations are:

1) Choose a diet that fits your needs. That is one of the things I like best about the US News & World Report ratings. The diets are categorized. If your main concern is diabetes, choose one of the top diets in that category. If your main concern is heart health… You get the point.

2) Choose diets that are healthy and associated with long term weight loss. If that is your goal, you will notice that primarily plant-based diets top these lists. Meat-based, low carb diets like Atkins and keto are near the bottom of the lists.

3) Choose diets that are easy to follow. The less-restrictive primarily plant-based diets top this list – diets like Mediterranean, DASH, MIND, and flexitarian.

4) Choose diets that fit your lifestyle and dietary preferences. For example, if you don’t like fish and olive oil, you will probably do much better with the DASH or flexitarian diet than with the Mediterranean diet.

5) In case you were wondering, intermittent fasting ranked 26-30 and the Paleo diet ranked 26-33 on most of the list – not the worst diets, but a long way from the best. If you have a favorite diet I didn’t mention, check the US News website to find where it is ranked.

6) Finally, focus on what you have to gain, rather than on foods you have to give up.

  • On the minus side, none of the diets include sodas, junk foods, and highly processed foods. These foods should go on your “No-No” list. Sweets should be occasional treats and only as part of a healthy meal. Meat, especially red meat, should become a garnish rather than a main course.
  • On the plus side, primarily plant-based diets offer a cornucopia of delicious plant foods you probably didn’t even know existed. Plus, for any of the top-rated plant-based diets, there are websites and books full of mouth-watering recipes. Be adventurous.

The Bottom Line 

For many of you the “bloom” has gone off the new diet you started so enthusiastically in January. If you are rethinking your diet, you might want to know which diets the experts recommend. Unfortunately, that’s not as easy as it sounds. The diet world has become just as divided as the political world.

Fortunately, you have an impartial resource. Each year US News & World Report invites a panel of experts with different points of view to evaluate popular diets. They then combine the input from all the experts into rankings of the diets in various categories. In the article above I summarize the US News & World Report’s “Best Diets In 2022”.

There are probably two questions at the top of your list.

#1: Which diets are best for rapid weight loss? Here are some general principles:

  • If you are looking for rapid weight loss, any whole food restrictive diet will do.
  • We should ask what happens when we get tired of restrictive diets and add back some of our favorite foods.
  • Long term weight loss is possible if you transition to a healthy diet after you have lost the weight.

#2: Which diet should you choose? Here the principles are:

  • Choose a diet that fits your needs.
  • Choose diets that are healthy and associated with long term weight loss.
  • Choose diets that are easy to follow.
  • Choose diets that fit your lifestyle and dietary preferences.
  • Finally, focus on what you have to gain, rather than on foods you have to give up.

Who Benefits Most From Supplementation?

Supplements Are Part of a Holistic Lifestyle

Author: Dr. Stephen Chaney

need for supplementsThe headlines about supplementation are so confusing. Are they useful, or are they a waste of money? Will they cure you, or will they kill you? I feel your pain.

I have covered these questions in depth in my book, “Slaying The Supplement Myths”, but let me give you a quick overview today. I call it: “Who Benefits Most From Supplementation?” I created the graphic on the left to illustrate why I feel responsible supplementation is an important part of a holistic lifestyle for most Americans. Let me give you specific examples for each of these categories.

 

Examples of Poor Diet

No Fast FoodYou have heard the saying that supplementation fills in the nutritional gaps in our diets, so what are the nutritional gaps? According to the USDA’s 2020-2025 Dietary Guidelines for Americans, many Americans are consuming too much fast and convenience foods. Consequently, we are getting inadequate amounts of calcium, magnesium, and vitamins A, D, E and C. Iron is considered a nutrient of concern for young children and pregnant women. In addition, folic acid, vitamin B6, and iodine are nutrients of concern for adolescent girls and pregnant women.

According to a recent study, regular use of a multivitamin is sufficient to eliminate all these deficiencies except for calcium, magnesium and vitamin D (J.B. Blumberg et al, Nutrients, 9(8): doi: 10.3390/nu9080849, 2017). A well-designed calcium, magnesium and vitamin D supplement may be needed to eliminate those deficiencies.

In addition, intake of omega-3 fatty acids from foods appears to be inadequate in this country. Recent studies have found that American’s blood levels of omega-3s are among the lowest in the world and only half of the recommended level for reducing the risk of heart disease (K.D. Stark et al, Progress In Lipid Research, 63: 132-152, 2016; S.V. Thuppal et al, Nutrients, 9, 930, 2017; M Thompson et al, Nutrients, 11: 177, 2019). Therefore, omega-3 supplementation is often a good idea.

In previous editions of “Health Tips From the Professor” I have talked about our “mighty microbiome”, the bacteria and other microorganisms in our intestine. These intestinal bacteria can affect our tendency to gain weight, our immune system, inflammatory diseases, chronic diseases such as diabetes, cancer, and heart diseases, our mood—the list goes on and on. This is an emerging science. We are learning more every day, but for now it appears our best chances for creating a health-enhancing microbiome are to consume a primarily plant-based diet and take a probiotic supplement.

Finally, diets that eliminate whole food groups create nutritional deficiencies. For example, vegan diets increase the risk of deficiencies in vitamin B12, vitamin D, calcium, iron, zinc and long chain omega-3 fatty acids. A recent study reported that the Paleo diet increased the risk of calcium, magnesium, iodine, thiamin, riboflavin, folate and vitamin D deficiency (A. Genomi et al, Nutrients, 8, 314, 2016). The Keto diet is even more restrictive and is likely to create additional deficiencies.

Examples of Increased Need

pregnant women taking omega-3We have known for years that pregnancy and lactation increase nutritional requirements. In addition, seniors have increased needs for protein, calcium, vitamin D and vitamin B12. In previous issues of “Health Tips From the Professor” I have also shared recent studies showing that protein requirements are increased with exercise.

Common medications also increase our need for specific nutrients. For example, seizure medications can increase your need for vitamin D and calcium. Drugs to treat diabetes and acid reflux can increase your need for vitamin B12. Other drugs increase your need for vitamin B6, folic acid, and vitamin K. Excess alcohol consumption increases your need for thiamin, folic acid, and vitamin B6. These are just a few examples.

Vitamin D is a special case. Many people with apparently adequate intake of vitamin D have low blood levels of 25-hydroxy vitamin D. It is a good idea to have your blood 25-hydroxy vitamin D levels measured on an annual basis and supplement with vitamin D if they are low.

More worrisome is the fact that we live in an increasing polluted world and some of these pollutants may increase our needs for certain nutrients. For example, in a recent edition of “Health Tips From the Professor” I shared a study reporting that exposure to pesticides during pregnancy increases the risk of giving birth to children who will develop autism, and that supplementation with folic acid during pregnancy reduces the effect of pesticides on autism risk. I do wish to acknowledge that this is a developing area of research. This and similar studies require confirmation. It is, however, a reminder that there may be factors beyond our control that have the potential to increase our nutritional needs.

Examples of Genetics Influencing Nutritional Needs

nutrigenomicsThe effect of genetic variation on nutritional needs is known as nutrigenomics. One of the best-known examples of nutrigenomics is genetic variation in the methylenetetrahydrofolate reductase (MTHFR) gene.  MTHFR gene mutations increase the risk of certain birth defects, such as neural tube defects. MTHFR mutations also slightly increase the requirement for folic acid. A combination of food fortification and supplementation with folic acid have substantially decreased the prevalence of neural tube defects in the US population. This is one of the great success stories of nutrigenomics. Parenthetically, there is no evidence that methylfolate is needed to decrease the risk of neural tube defects in women with MTHFR mutations.

Let me give you a couple of additional examples:

One of them has to do with vitamin E and heart disease (A.P. Levy et al, Diabetes Care, 27: 2767, 2004). Like a lot of other studies there was no significant effect of vitamin E on cardiovascular risk in the general population. But there is a genetic variation in the haptoglobin gene that influences cardiovascular risk. The haptoglobin 2-2 genotype increases oxidative damage to the arterial wall, which significantly increases the risk of cardiovascular disease. When the authors of this study looked at the effect of vitamin E in people with this genotype, they found that it significantly decreased heart attacks and cardiovascular deaths.

This has been confirmed by a second study specifically designed to look at vitamin E supplementation in that population group (F. Micheletta et al, Arteriosclerosis, Thrombosis and Vascular Biology, 24: 136, 2008). This is an example of a high-risk group benefiting from supplementation, but in this case the high risk is based on genetic variation.

Let’s look at soy and heart disease as a final example. There was a study called the ISOHEART study (W.L. Hall et al, American Journal of Clinical Nutrition, 82: 1260-1268, 2005 (http://ajcn.nutrition.org/content/82/6/1260.abstract); W.L. Hall et al, American Journal of Clinical Nutrition, 83: 592-600, 2006) that looked at a genetic variation in the estrogen receptor which increases inflammation and decreases levels of HDL. As you might expect, this genotype significantly increases cardiovascular risk.

Soy isoflavones significantly decrease inflammation and increase HDL levels in this population group. But they have no effect on inflammation or HDL levels in people with other genotypes affecting the estrogen reception. So, it turns out that soy has beneficial effects, but only in the population that’s at greatest risk of cardiovascular disease, and that increased risk is based on genetic variation.

These examples are just the “tip of the iceberg”. Nutrigenomics is an emerging science. New examples of genetic variations that affect the need for specific nutrients are being reported on a regular basis. We are not ready to start genotyping people yet. We don’t yet know enough to design a simple genetic test to predict our unique nutritional needs. That science is 10-20 years in the future, but this is something that’s coming down the road.

What the current studies tell us is that some people are high-risk because of their genetic makeup, and these are people for whom supplementation is going to make a significant difference. However, because genetic testing is not yet routine, most people are completely unaware that they might be at increased risk of disease or have increased nutritional requirements because of their genetic makeup.

Examples of Disease Influencing Nutritional Needs

Finally, let’s consider the effect of disease on our nutritional needs. If you look at the popular literature, much has been written about the effect of stress on our nutritional needs. In most case, the authors are referring to psychological stress. In fact, psychological stress has relatively minor effect on our nutritional needs.

Metabolic stress, on the other hand, has major effects on our nutritional needs. Metabolic stress occurs when our body is struggling to overcome disease, recover from surgery, or recover from trauma. When your body is under metabolic stress, it is important to make sure your nutritional status is optimal.

The effects of surgery and trauma on nutritional needs are well documented. In my book, “Slaying The Supplement Myths”, I discussed the effects of disease on nutritional needs in some detail. Let me give you a brief overview here. It is very difficult to show beneficial effects of supplementation in a healthy population (primary prevention). However, when you look at populations that already have a disease, or are at high risk for disease, (secondary prevention), the benefits of supplementation are often evident.

For example, studies suggest that vitamin E, B vitamins, and omega-3s each may reduce heart disease risk, but only in high-risk populations. Similarly, B vitamins (folic acid, B6 and B12) appear to reduce breast cancer risk in high risk populations.

Who Benefits Most From Supplementation?

Question MarkWith this information in mind, let’s return to the question: “Who benefits most from supplementation? Here is my perspective.

1) The need for supplementation is greatest when these circles overlap, as they do for most Americans.

2) The problem is that while most of us are aware that our diets are not what they should be, we are unaware of our increased needs and/or genetic predisposition. We are also often unaware that we are at high risk of disease. For too many Americans the first indication they have heart disease is sudden death, the first indication of high blood pressure is a stroke, or the first indication of cancer is a diagnosis of stage 3 or 4 cancer.

So, let’s step back and view the whole picture. The overlapping circles are drawn that way to make a point. A poor diet doesn’t necessarily mean you have to supplement. However, when a poor diet overlaps with increased need, genetic predisposition, disease, or metabolic stress, supplementation is likely to be beneficial. The more overlapping circles you have, the greater the likely benefit you will derive from supplementation.

That is why I feel supplementation should be included along with diet, exercise, and weight control as part of a holistic approach to better health.

The Bottom Line

In this article I provide a perspective on who benefits most from supplementation and why. There are four reasons to supplement.

  1. Fill Nutritional gaps in our diet

2) Meet increased nutritional needs due to pregnancy, lactation, age, exercise, many common medications, and environmental pollutants.

3) Compensate for genetic variations that affect nutritional needs.

4) Overcome needs imposed by metabolic stress due to trauma, surgery, or disease.

With this information in mind, let’s return to the question: “Who benefits most from supplementation? Here is my perspective.

  1. A poor diet alone doesn’t necessarily mean you have to supplement. However, when a poor diet overlaps with increased need, genetic predisposition, or metabolic stress, supplementation is likely to be beneficial. The more overlap you have, the greater the likely benefit you will derive from supplementation.

2) The problem is that while most of us are aware that our diets are not what they should be, we are unaware of our increased needs and/or genetic predisposition. We are also often unaware that we are at high risk of disease. For too many Americans the first indication they have heart disease is sudden death, the first indication of high blood pressure is a stroke, or the first indication of cancer is a diagnosis of stage 3 or 4 cancer.

Does Time-Restricted Eating Have A Downside?

Are The Benefits Of Time-Restricted Eating An Illusion?

 Author: Dr. Stephen Chaney

intermittent fastingWeight loss is difficult. If you are like most American adults, you have tried at least 5 or 6 diets by the time you are 50, and all of them have failed. Or maybe you have found a diet that works reasonably well at helping you lose weight, but it’s difficult to stick with. And you worry that it may not be healthy long-term.

But hope springs eternal, and there are always new diets to try. One of the newer diet fads is something called intermittent fasting. The most popular form of intermittent fasting (because it is the easiest to follow) is something called time-restricted eating.

The concept is simple. You don’t change what you are eating. Instead, you restrict the time during which you are eating those foods. Typically, you restrict your time of eating to 8 hours a day and abstain from all food the rest of the day. Hence, the term “time-restricted eating”.

I won’t go into the supposed benefits of time-restricted eating. You have probably heard those already from advocates of this form of eating. But you may be wondering if those benefits are true and whether time-restricted eating has any drawbacks.

Fortunately, a recent study (T Moro et al, Medicine and Science In Sports & Exercise, 53, 2577-2585, 2021) answers those questions. It put a group of athletes on either a control diet or a time-restricted diet for an entire year and looked at the relative benefits and drawbacks of both diets.

How Was This Study Done?

Clinical StudyThis study recruited 19 healthy, resistance-trained males (average age = 29, average weight = 185 pounds) for the study. All the subjects had at least 5 continuous years of resistance training, no steroid use, and no known medical conditions.

The subjects completed a 7-day food diary prior to the study, at the end of 2 months, and at the end of 12 months. The participants were instructed not to change their usual caloric intake or diet composition. In addition, each participant received a personalized diet protocol based on the analysis of their food diary at baseline.

The results from the first two months have previously been reported (T Moro et al, Journal of Translational Research, 14: 290, 2016). This report covers the subsequent 10 months.

During the first two months, the participants were contacted weekly by a dietitian to ensure adherence to the diet. During the interviews, the dietitian asked questions about meal timing and composition, appetite, and any difficulties in maintaining the diet protocol. When necessary, the dietitian gave advice to improve adherence to the diet. During the subsequent 10 months, the participants were contacted less frequently, and the interviews were shorter.

The participants were divided into two groups. The selection was random except that the two groups were matched with respect to caloric intake at baseline (~2,900 calories/day).

The ND (normal meal distribution) group ate their meals over a 12-hour period, with meals at ~8AM, 1 PM, and 8 PM. The distribution of calories for this group was 25%, 40%, and 35% over the three meals.

The TRE (time-restricted eating) group ate their meals over an 8-hour period, with meals at ~1PM, 4 PM, and 8 PM. The distribution of calories for this group was 40%, 25%, and 35% over the three meals.

The training regimen consisted of strength training specifically designed to increase muscle mass. A standardized 3-times per week training regimen was established during the first two months of supervised training. The participants continued the same training regimen on their own for the next 10 months. Workouts were performed between 4 and 6 PM to fall within the eating window for both groups.

Finally, tests for inflammatory markers, cholesterol & other blood lipids, blood sugar control, hormones, body composition, and strength were performed before the program started, at 2 months, and again at 12 months.

What Are The Benefits Of Time Restricted Eating?

thumbs upWhen the investigators looked at health outcomes at the end of 12 months:

  • Inflammatory markers were significantly reduced in the TRE (time-restricted eating) group compared to the ND (normal meal distribution) group.
  • Blood sugar control was significantly improved in the TRE group compared to the ND group.
  • Lipid profiles were significantly improved in the TRE group compared to the ND group.

These results are consistent with the findings of earlier short-term studies on the benefits of time restricted eating.

The authors concluded. “Our results suggest that long-term time-restricted eating in combination with a resistance training program is feasible, safe, and effective in reducing inflammatory markers and risk factors.”

At this point you are probably thinking, “It sounds like everything I have heard about time-restricted eating is true. I can’t wait to get started.”

What Causes The Benefits Of Time-Restricted Eating?

SkepticBefore you jump on the time restricted eating bandwagon, let’s look more closely and ask what caused these apparent health benefits.

When the investigators looked at changes in caloric intake over the 12-month period:

  • The TRE group spontaneously decreased their total caloric intake by 6.4% in spite of being told not to change their diet.
    • The decrease in caloric intake was driven by a decrease in both carbohydrate and fat intake, while protein intake remained constant.
    • Most of this change occurred between 2 and 12 months when they were no longer being closely supervised by dietitians.
  • In contrast, caloric intake and macronutrient intake did not change significantly for the ND group.

The reason for the decrease in caloric intake is not known.

  • If you follow social media or blogs about time-restricted eating, you have been given some scientific-sounding mumbo-jumbo about how the 16 hours of fasting changes your metabolism and/or reduces your appetite. However, this is speculation. There is scant evidence for it.
  • A more likely explanation is that when you restrict the time you allow yourself to eat, you naturally eat less without thinking about it. You are simply less hungry when the second and third meals roll around. [This may explain why even these highly disciplined athletes required weekly coaching by dietitians to keep their caloric intake constant.]

And when the investigators looked at changes in body weight over the 12-month period:

  • The TRE group lost 3.4% of their body weight.
    • Most of that weight loss was due to a decrease in fat mass, but there was also a loss of muscle mass.
  • In contrast the ND group increased their total body weight by 3.4%.
    • In other words, at the end of 12 months the difference between the TRE and ND groups amounted to almost 7% of their body weight. This difference was highly significant.
    • Most of the increase in body weight in the ND group was due to a 2.9% increase in muscle mass.

These results are also consistent with the findings of earlier studies of time-restricted eating.

The observed decrease in body weight and fat mass is important because whenever you decrease body weight and fat mass, you:

  • Reduce inflammatory markers.
  • Improve blood sugar control.
  • Improve lipid profiles.

In the words of the authors, “…it is plausible that the caloric reduction observed in the TRE group may have contributed to the reductions in body mass and additional health benefits…”

Of course, that still sounds pretty good. Who wouldn’t want to lose weight and get healthier? But are the weight reduction and health benefits unique to time-restricted eating? That is the claim of those who promote this diet.

But is it true? To answer that question, we need to take a broader view of popular diets. We need to ask, “Is something special about time-restricted eating, or would other restrictive diets give similar results?”

Are The Benefits Of Time-Restricted Eating An Illusion?

The TruthThere are two diet truths that nobody is talking about:

1) Forget the metabolic mumbo-jumbo. The primary reason restrictive diets cause you to lose weight is that you unconsciously eat less while you are on these diets.

For time-restricted eating, you eat less because you have restricted the time when you can eat. With other restrictive diets, you have restricted the foods you can eat. The reason why that causes you to eat less is more subtle. I call it the “Bagels and Cream Cheese Effect”.

    • When you go on a low-fat diet, it sounds great to say you can eat all the bagels you want. But without the cream cheese, bagels become boring, and you eat less.
    • When you go on a low-carb diet, it sounds great to say you can eat all the cream cheese you want. But without the bagels, cream cheese becomes boring, and you eat less.

2) The proponents of fad diets make them look good by comparing them to the typical American diet. Anything is better than the American diet. However, when you make the comparisons based on the reduction in caloric intake or the amount of weight lost, the health benefits of popular diets are virtually identical. For example:

    • When you compare the Atkins diet and other low carb diets with the typical American diet, inflammation is lower on the low carb diets. However, one recent study compared people on the Atkins diet with people who had lost an equal amount of weight on a balanced diet that included all food groups. Guess what? Inflammation is much higher on the Atkins diet when you compare it to a healthy diet that gives equal weight loss.
    • This study reported that the time-restricted eating group ate less, lost more weight, and had better health parameters than the control group. However, previous studies that compared time-restricted eating with groups that reduced caloric intake to the same extent by simply counting calories have found the two groups had identical weight loss and improvement in health parameters.

In other words, there is nothing magical about time-restricted eating. Any diet that causes you to eat less will give identical results. There are only two questions left:

  1. Can you stick with time-restricted eating long term?

Time-restricted eating is not everyone’s cup of tea. But this study suggests that if you can stick with it better than with other restrictive diets, you are likely to lose weight and reap some health benefits.

2) Should you stick with time-restricted eating long term?

To answer this question, you need to know whether there are any downsides to time-restricted eating.

Does Time-Restricted Eating Have A Downside?

thumbs down symbolOf course, most people would consider weight loss and an improvement in health parameters as a definite plus. It’s all good. Or is it? Does time-restricted eating have any downsides? This study identified two potential downsides:

1) Decreased anabolic hormones.

    • Anabolic hormones (hormones that stimulate an increase in muscle mass) were decreased in the TRE group. Specifically:
      • Testosterone was decreased by 17% at the end of 12 months in the TRE group.
      • Insulin-like growth factor-1 (IGF-1) was decreased by 14% in the TRE group.
    • Both anabolic hormone levels were unchanged in the ND group.

2) Decreased muscle mass. Between months 2 and 12:

    • Muscle mass was decreased by 2.3% in TRE group and increased by 2.9% in the ND group.
    • The cross-sectional area of arm and thigh muscles was decreased by an average of 4.3% in the TRE group and increased by an average of 8.5% in the ND group.

In the words of the authors, “With our results, we confirmed that a long-term TRE protocol could impair the ability of maintaining muscle mass, possibly because of a reduction in caloric intake and a direct effect of fasting on the production of anabolic hormones.”

That is putting it mildly. The participants in this study were engaged in a rigorous 3-times/week strength training program specifically designed to increase muscle mass and were consuming over 100 grams of protein a day. So, a continuous increase in muscle mass and cross-sectional area would be expected. This was seen in the ND group but not in the TRE group, which actually lost muscle mass. The average “Joe” or “Jane” would likely lose even more muscle on this diet.

And continuous, long-term loss of muscle mass has significant health consequences including:

  • Decreased metabolic rate, which makes it more difficult to maintain a healthy weight.
  • Decreased insulin sensitivity, which increases the risk of diabetes.
  • Increased risk of osteoporosis.
  • Muscle weakness, which increases the risk of falling.

Dr. Paoli, the lead scientist on this study, was quoted as saying, “The main take home message is that there are pros and cons to prolonged time-restricted eating. Although time-restricted eating may produce some physiological advantages, it is not a miracle as often suggested in social media posts.”

The Bottom Line 

A recent study looked at the pros and cons of following a time-restricted eating (TRE) diet compared to a diet with normal meal distribution (ND) for 12 months.

  • The TRE group had reduced inflammation, better blood sugar control, and better lipid profiles than the ND group.

However, the improved health parameters were not caused by some magical metabolic changes due to fasting.

  • The TRE group unconsciously reduced their caloric intake and lost weight compared to the ND group. And any time you lose weight, you get reduced inflammation, better blood sugar control, and better lipid profiles.

In the words of the authors, “…it is plausible that the caloric reduction observed in the TRE group may have contributed to the reductions in body mass and additional health benefits…”

And there is nothing unique about time-restricted eating.

  • Any restrictive diet is likely to give similar results. (For more details, read the article above.)

Finally, there were some significant downsides to time-restricted eating.

  • The TRE group had a reduction in anabolic hormones and lost muscle mass.

In the words of the authors, “With our results, we confirmed that a long-term TRE protocol could impair the ability of maintaining muscle mass, possibly because of a reduction in caloric intake and a direct effect of fasting on the production of anabolic hormones.”

This is putting it mildly. The participants in this study were engaged in a rigorous 3-times/week strength training program specifically designed to increase muscle mass and were consuming over 100 grams of protein a day. They should have gained muscle mass. Instead, they lost it.

Continuous, long-term loss of muscle mass has significant health consequences including:

  • Decreased metabolic rate, which makes it more difficult to maintain a healthy weight.
  • Decreased insulin sensitivity, which increases the risk of diabetes.
  • Increased risk of osteoporosis.
  • Muscle weakness, which increases the risk of falling.

Dr. Paoli, the lead scientist on this study, was quoted as saying, “The main take home message is that there are pros and cons to prolonged time-restricted eating. Although time-restricted eating may produce some physiological advantages, it is not a miracle as often suggested in social media posts.”

How I Treated My Frozen Shoulder

Why We Get Shoulder Pain

Editor: Dr. Steve Chaney 

Happy New Year

celebrationI love the holidays!  It’s wonderful to see family and friends, and there’s always such good food and fun, but I’m also happy when the New Year begins.  Of course, every day is a “new year”, but January 1st is like starting a whole new book of life, with unlimited possibilities.

This year, I’m not only writing goals, I am also doing something that was suggested by Pegine Echevarria.  I’m looking back on this past year and writing down as many of my successes as I can remember.  Goals are the roadmap for the future, but remembering past successes lifts our confidence that we’ll be able to achieve the goals we have set.

In fact, this year I’m going to look at each day and write down a success that I’ve had that day. How wonderful it will be on New Year’s Eve to look back and read 365 successes for 2020!

I hope you had a wonderful holiday season and that you’re also eager about starting 2020.  Here’s to a year of adventure, joy, health, prosperity, and fulfillment of all your dreams!

Why We Get Shoulder Pain

For some reason I’ve had a LOT of clients come in with shoulder issues this month, more than normal, so it made me decide that this month’s topic should be about the shoulder.

The shoulder has more muscle attachments than any other joint in the body, which Is the reason we have such a wide assortment of movements we can make with our shoulder and arm.

There are 16 different muscles that impact your shoulder and cause movement and stability to the joint.  Each muscle is pulling in a different direction, and that’s a blessing, and a potential problem.

For example, when one muscle is trying to pull your arm forward, and the muscle that pulls your arm back is in spasm, you will have pain every time you try to move your arm to drive a car, type at your computer, or lift anything up.  And the pain can get severe if it’s not treated properly and quickly.

How I Treated My Frozen Shoulder

In 1993 I had the worst case of frozen shoulder I’ve ever seen in anyone before or since.

Every one of the 16 muscles had gone into a sudden spasm, pulling in 16 different directions.  It locked my elbow to my waistline and even the slightest movement in any direction caused excruciating shoulder joint pain.  Nobody could figure out what to do and I ended up tying my arm to my body to stop the stabbing hot knife pains I felt with even the slightest movement.  It was horrible! I knew what I would do to help you, but I couldn’t find anyone who could do those same treatments for me.  What to do?!

You know that voice that’s forever running in your head?  I was frantic and said out loud, ”What the heck am I going to do?” And a voice in my head said to me “treat yourself!”  Really, now how was I going to self-treat all these muscles when I had absolutely no movement in my left arm?  The voice said: “figure it out!”  So, I did!

It wasn’t easy, and it was definitely painful, but step-by-step I worked out how to treat each muscle using a ball, and my fingertips.  It took me five months to get back to 100% mobility, but I did it.  Next thing I knew every client who came to my office was suffering from shoulder pain. Nobody was as severe as I had been, but their situation was still very painful and limiting them in many ways.

I realized that I wouldn’t have gotten full range-of-motion back if I hadn’t been self-treating several times a day, so I started to teach my clients how to help themselves.  I didn’t have any pictures yet so I could only show them one or two techniques each time they came in, but it made a huge difference.  People started getting better, and I moved on to a new aspect of my therapy practice -– teaching people how to self-treat for permanent pain relief.pain free living book

Eventually I took pictures of each self-treatment, and I hand wrote a description of what the picture was demonstrating.  I didn’t have a computer yet, but that’s another long story about how it all became my first book (the title was so long, even I don’t remember it!).  I learned to have short titles for each book, and now every treatment I teach is in either Treat Yourself to Pain-Free Living, The Pain-Free Athlete, or The 15 Minute Back Pain Solution. 

If you have been to see me for therapy, you know that I teach you what to do at home.  That’s definitely something most massage therapists don’t do, but my feeling is I’m only successful if you are out of pain and you stay that way.

One Important Shoulder Self-Treatment You Can Use First

We’ll demonstrate on the left arm:

 

Put a ball in your right hand and then bring your hand under your left armpit or you can place the ball as shown in the picture.

 

 

 

Lean onto a wall, moving until you find the “hot spot.”

Stay there for about a minute, either staying still or moving very slightly.

Take the pressure off the ball to let blood get into the area and repeat several times.

 

Move about, bringing the ball up further into your shoulder blade, and down toward your armpit (treating the latissimus dorsi muscle).

There Is So Much More

As I mentioned, there are 16 muscles involved in moving our shoulder and arm, and this is only one technique to ease pain and stiffness.  In my opinion, this is the #1 treatment I always teach because it helps so much, but the others are important too.

You can get every self-treatment in Treat Yourself to Pain-Free Living and The Pain-Free Athlete. 

I’m also opening a weekly Zoom gathering that comes with 24/7/365 access to all the tools you need to find and release aches and pains from your head to your feet.  You can get information about it by going to www.Pain-FreeAthlete.com.

Wishing you well,

Can Your Diet Cause You To Lose Your Mind?

What Is A Mind-Healthy Lifestyle? 

Author: Dr. Stephen Chaney

Cognitive-DeclineMost of us look forward to our golden years – that mystical time when we will be free from the workday pressures and have more time to spend with friends and family doing the things we love.

But cognitive decline can cast a dark cloud over those expectations.

  • By the age of 65, 11% of adults suffer from some degree of cognitive impairment.
  • And by the age of 80 the percentage of adults suffering from cognitive impairment has increased to 26-30%, depending on which study you cite.

The results of cognitive decline can be devastating.

  • First you start to lose the cherished memories of a lifetime.
  • Then comes confusion and an inability to perform basic tasks and participate in your favorite activities.
  • Eventually you may reach a stage where you no longer recognize the ones you love.

In short, cognitive decline can rob you of everything that makes you you.

The causes of cognitive decline are complex, but recent studies have pointed to the role of chronic inflammation in cognitive decline. If that is true, it is a good news – bad news situation.

  • The bad news is:
    • Some increase in chronic inflammation appears to be an inevitable consequence of aging.
    • Chronic inflammation can be caused by certain diseases that are beyond our control.
    • Chronic inflammation can be triggered by viral or bacterial infections.
  • The good news is that chronic inflammation is also controlled by your diet and lifestyle. For example, as I said above, chronic inflammation is often triggered by a viral infection, but whether the inflammation is mild or severe is strongly influenced by diet and lifestyle.

In this issue of “Health Tips From the Professor” I share a study (S Charisis et al, Neurology, In Press, November 10, 2021) showing that diets high in inflammatory foods increase the risk of dementia. Then, I answer 3 important questions.

  • Can your diet cause you to lose your mind?
  • What is a mind-healthy diet?
  • What is a mind-healthy lifestyle?

How Was This Study Done?

Clinical StudyThe data for this study were taken from the first three years of the Hellenic Longitudinal Investigation of Aging and Diet (HELIAD), a study designed to look at the effect of diet on dementia and other neuropsychiatric conditions in the Greek population.

There were 1059 participants (40% male, average age = 75 at the beginning of the study) in this study. At the beginning of the study the participants completed a food frequency questionnaire administered by a trained dietitian. The foods were broken down into individual nutrients using the USDA Food Composition tables adapted for foods in the Greek diet.

The diet of each participant was then rated on a 15-point scale ranging from pro-inflammatory to anti-inflammatory based on something called the Diet Inflammation Index (DII).

Simply put, the DII is a validated assessment tool based on the effect of food nutrients on 6 inflammatory biomarkers found in the blood (IL-1β, IL-4, IL-6, IL-10, TNF-α, and CRP). Nutrients that decrease these markers are considered anti-inflammatory. Nutrients that increase these inflammatory biomarkers are considered pro-inflammatory.

For example, anti-inflammatory nutrients include:

  • Carotenoids and flavonoids (found in fruits and vegetables).
  • Omega-3 polyunsaturated fatty acids (found in cold-water fish, walnuts, flaxseeds, and chia seeds).
  • Monounsaturated fatty acids (found in olive, avocado, and peanut oils).
  • Fiber (found in minimally processed plant foods).
  • Antioxidants, most B vitamins, and vitamin D.
  • Magnesium and zinc.
  • Garlic, onions, most herbs & spices.

Pro-inflammatory nutrients include:

  • Refined carbohydrates.
  • Cholesterol.
  • Total fat.
  • Saturated fats.
  • Trans fats.

The participants were followed for 3 years, and all new diagnoses of dementia were recorded. The diagnoses were confirmed by a panel of neurologists and neuropsychologists.

Can Your Diet Cause You To Lose Your Mind?

Forgetful Old ManAs described above, the diet of each participant in the study was rated on a 15-point DII (Diet Inflammatory Index) scale ranging from pro-inflammatory to anti-inflammatory. The association of the DII score of the participant’s diets with the onset of dementia was evaluated in two ways.

  • Each one-point increase from an anti-inflammatory diet to a pro-inflammatory diet was associated with a 21% increase in the risk for dementia.
  • In other words, even small changes in your diet can have a significant impact on your risk of developing dementia.

The investigators then divided the participants into three equal-sized groups based on the DII score of their diets.

  • The group with the highest DII scores were 3 times more likely to develop dementia than the group with the lowest DII scores.
  • In other words, a major change in your diet can have a major effect on your risk of developing dementia.

The authors concluded, “In the present study, higher DII scores (indicating greater pro-inflammatory diet potential) were associated with an increased risk for incident dementia [newly diagnosed dementia]. These findings may avail the development of primary dementia strategies through tailored and precise dietary interventions.”

What Is A Mind-Healthy Diet?

Vegan FoodsThis and other studies show that an anti-inflammatory diet is good for the mind. It helps protect us from cognitive decline and dementia. But what does an anti-inflammatory diet look like?

One hint comes from analyzing the diets of participants in this study:

  • Those with the lowest DII scores (most-anti-inflammatory diets) consumed 20 servings of fruit, 19 servings of vegetables, 4 servings of beans or other legumes, and 11 servings of coffee or tea each week. That’s almost 3 servings of fruit and 3 servings of vegetables every day!
  • Those with the highest DII scores (most pro-inflammatory diets) consumed only half as many fruits, vegetables, and legumes.
  • In short, a diet rich in fruits, vegetables, and legumes is a good start.

I have described anti-inflammatory diets in more detail in a previous issue of “Health Tips From the Professor.” Let me summarize that article briefly.

Anti-inflammatory foods include:

  • Colorful fruits and vegetables.
  • Whole grains.
  • Beans and other legumes.
  • Nuts, olive oil, avocados, and other sources of monounsaturated fats.
  • Fatty fish and other sources of omega-3 fatty acids.
  • Herbs and spices.

Pro-inflammatory foods include:

  • Refined carbohydrates, sodas, and sugary foods.
  • Foods high in saturated fats including fatty and processed meats, butter, and high fat dairy products.
  • Foods high in trans fats.
  • French fries, fried chicken, and other fried foods.
  • Foods you are allergic or sensitive food. For example, gluten containing foods are pro-inflammatory only if you are sensitive to gluten.

If your goal is to reduce chronic inflammation and keep your mind sharp as a tack as you age, you should eat more anti-inflammatory foods and less pro-inflammatory foods.

Of course, we don’t just eat random foods, we follow dietary patterns. It should be apparent from what I have Mediterranean Diet Foodscovered above that whole food, primarily plant-based diets are anti-inflammatory. This is true for diets ranging from vegan through semi-vegetarian, to the Mediterranean, DASH, and MIND diets.

All these diets are anti-inflammatory and likely protect the brain from cognitive decline. However, the best evidence for brain protection is for the Mediterranean, DASH, and MIND diets.

  • The Mediterranean and DASH diets have been shown to prevent cognitive decline in multiple studies.
  • The MIND diet is a combination the Mediterranean and DASH diets that was specifically designed to prevent cognitive decline. It has been shown to cut the risk of developing Alzheimer’s disease in half.

What Is A Mind-Healthy Lifestyle?

Diet is just one aspect of a holistic approach for reducing cognitive decline as we age. Other important factors include:

  • Reduce excess body weight.
  • Exercise regularly.
  • Get adequate sleep.
  • Reduce and/or manage stress.
  • Eliminate smoking and reduce alcohol consumption.
  • Socialize with friends and family who support you. Numerous studies have shown that a strong support network reduces dementia risk in the elderly.
  • Keep your brain active. Work crossword puzzles. Learn new things. An active brain is forced to lay down new neural pathways.

The Bottom Line 

Recent studies have suggested that chronic inflammation increases the risk of cognitive decline and dementia as we age. Some causes of chronic inflammation are beyond our control, but others, such as diet, we can control.

Recently, a precise scoring system called the Diet Inflammatory Index (DII) has been developed. This scoring system allows studies to look at the correlation between the inflammatory potential of the diet and cognitive decline.

A recent study enrolled 1,000 participants with an average age of 75 in a 3-year study to determine the impact of diet on cognitive decline. The association of the DII score of the participant’s diets with the onset of dementia was evaluated in two ways.

  • Each one-point increase from an anti-inflammatory diet to a pro-inflammatory diet was associated with a 21% increase in the risk for dementia.
  • In other words, even small changes in your diet can have a significant impact on your risk of developing dementia.

The investigators then divided the participants into three equal-sized groups based on the DII score of their diets.

  • The group with the highest DII scores were 3 times more likely to develop dementia than the group with the lowest DII scores.
  • In other words, a major change in your diet can have a major effect on your risk of developing dementia.

The authors concluded, “In the present study, higher DII scores (indicating greater pro-inflammatory diet potential) were associated with an increased risk for incident dementia [newly diagnosed dementia]. These findings may avail the development of primary dementia strategies through tailored and precise dietary interventions.”

Can You Lose Weight Without Going On A Diet?

8 Tips For Eating Less

Author: Dr. Stephen Chaney 

New Year DietYou have just made your New Year’s resolutions, and weight loss is probably near the top of the list. You may be considering the latest new diet fad – never mind that you’ve tried lots of diets in the past and have always regained the weight you lost.

Perhaps the very thought of going on a diet terrifies you. You are tired of struggling to follow strict “rules” and forgoing all your favorite foods. You are tired of constantly being hungry.

What if you could lose weight without going on a diet? What if you could learn just a few tricks that would help you eat less every day? Would that be of interest to you? Do you think it might help you lose some weight and keep it off?

This week I’m going to share 8 tips for eating less every single day from Professor Brian Wansink of Cornell University. He is Director of their Food and Brand Lab. He has devoted his career to studying how external clues influence our eating patterns. He is the author of the best-selling books “Mindless Eating” and “Slim by Design”. He is the world expert on this topic.

A few years ago, I had the pleasure of attending a seminar he gave. Here’s a quick summary of what I learned.

8 Tips For Eating Less

Tip #1: The Size Of The Container Matters

Popcorn bagsIn one of his research studies he gave moviegoers who had just eaten dinner either a big bag or a small bag of stale popcorn. Those given the big bag ate 34% more. Think about that for a minute. The subjects in his study weren’t hungry. They had just eaten dinner. The popcorn wasn’t particularly tasty. It was stale. Yet they ate 34% more based solely on the size of the bag!

The take home lesson is always to choose the smallest container when given a choice. This is also why you want to serve your meals on small plates and drink your beverages in small glasses or cups. If you want to snack while you watch TV, place your snack food in a very small container and store the rest out of sight.

Tip #2: Don’t Fall For Marketing Hype

He was asked to consult for a cafeteria serving health food because they weren’t attracting enough customers. He just advised them to change the names of their menu items (e.g. “Succulent Tuscany Pasta” instead of “Italian Pasta”). Sales increased by 27%.

The take home lesson is not to fall for the marketing hype. Restaurants and food manufacturers know all the tricks. They know how to make even ordinary foods sound delicious. Make your food choices based on the ingredients of the food, not on the marketing description.

Tip #3: Make Junk Food InconvenientCandy Dish

In another study he put clear glass dishes of candy either on a secretary’s desk or 6 feet away on a cabinet. The secretaries consumed 125 more calories/day from candy when it was on their desk. Think about that for a minute. 125 excess calories/day could amount to around one pound of weight gain/month, 12 pound/year, 60 pounds every 5 years, and a whopping 120 pounds over 10 years!

The take home lesson is to make high calorie snacks and junk foods inconvenient. Put them in the back of your refrigerator, on the top shelf of your cabinets, or other out of the way places. Even better, don’t bring them home in the first place.

Tip #4: Watch The Refills.

When he used a refillable soup bowl (it never goes below half full) people ate 73% more soup than those given a regular bowl of soup. When he asked the people with the refillable bowl if they were full, they replied “How could I be? I only ate half a bowl of soup”.

Of course, most of us will never experience a refillable soup bowl. However, if you are having a meal with friends and enjoying the conversation, it is easy to ignore the refills – either from your waiter at a restaurant or your favorite aunt at a family gathering.

Tip #5: Low Fat Doesn’t Mean “Eat More”

lowfatWhen he took a batch of trail mix and labeled some as “low fat” and some as “regular” people ate 21% to 46% more calories of the “low fat” trail mix. This was not an idle exercise. In fact, many low fat foods aren’t low calorie, but people assume that they are and use that as an excuse to eat more.

The take home lesson is to not assume you can eat more just because a food is labeled low fat, gluten free or some other healthy sounding description. In many cases, it has just as many calories as the full fat version. Even if it is, in fact, lower in calories, the only way you benefit from the reduced calories is when you consume the same portion size as you would for the full fat food it replaces.

Tip #6: Health Foods Are Not Necessarily Healthy

When he showed people an Italian sandwich and told them that it was from either “Jim’s Hearty Sandwich Shop” or from “Good Karma Healthy Foods”, people estimated the calories as 24% lower if they thought it came from Good Karma.

The take home lesson is that health foods are not necessarily healthier. Food manufactures know that health food is in, and they market their products accordingly. If you walk down the aisles of your favorite health food store, you will find “health” foods that are just as high in sugar, fat and calories as the junk food you can buy at the convenience store down the street. They may contain “natural” fats and sugars, but those have just as many calories as the “unhealthy” fats and sugars in the junk foods. You still need to read labels and choose unprocessed fruits, vegetables and whole grains whenever possible.

Tip #7: Don’t Call It ExerciseNature Walk

When he took students on a walk around a lake before dinner, they ate more calories at dinner if they were told that it was an exercise walk than if they were told that it was a sight-seeing walk – and most of the extra calories came from dessert. Think about that for a minute. It is a human tendency to reward ourselves for virtuous behavior, but when that reward involves eating, it becomes self-defeating.

The take home lesson is two-fold.

  • Reframe our virtuous behavior. If we call it exercise or a work-out, it implies that we have done something virtuous and deserve a reward. If we call it a nature walk or think of it as a sport, it becomes its own reward. If we think of substituting a salad for a dinner of fried chicken and mashed potatoes with gravy as virtuous behavior, we may think we deserve a dessert as a reward. If we think of the salad as a gourmet experience, it can become a reward in its own right.
  • Rethink our rewards. The reward doesn’t need to be food related. It could involve reading a book, watching a show, or whatever you favorite activity might be.

Tip #8: Knowing This Stuff Isn’t Enough.

The fascinating thing is that his research shows it doesn’t matter how intelligent or well informed you are.

He did a study with 60 graduate students. Just before winter break, he gave them a lecture on external eating cues in which he specifically told them that they would eat more from a big bowl of Chex Mix than from a small bowl. The students then spent 90 minutes in small group exercises designed to show them how to overcome external eating cues.

After winter break he invited those same students to a Super Bowl party in which he divided them into two rooms and gave them, you guessed it, either large or small bowls of Chex Mix. The ones given the large bowls ate 53% more!

He later gave the same lecture to a meeting of The American Diabetes Association (Those are the experts) and then repeated the same experiment with them – and they still ate more from the large bowls.

Can You Lose Weight Without Going On A Diet?

Question MarkThat brings us back to the original question, “Can you lose weight without going on a diet?” You can start by decreasing the amount of food you eat.

Dr. Wansink’s research clearly shows that overeating is mindlessly dependent on external eating cues, AND that you can’t avoid being influenced by those external clues even if you are intelligent and motivated! So what can you do?

Dr. Wansink recommends planning ahead. For example:

  • Serve your food on small plates and don’t leave food lying around where you can see it or get to it easily.
  • If you bring home a box or bag of snack food (hopefully healthy snack food), divide it up into healthy portion sizes as soon as you bring it home.
  • Put the healthy food choices in the front of your refrigerator or cupboard where you will see them easily and hide the unhealthy foods in the back (or don’t bring them home to begin with).

However, the most important thing is to realize most of this behavior is mindless. It is not enough to simply understand these external eating cues at an intellectual level. We need to be constantly vigilant for external eating cues, or we will find ourselves overeating without really understanding why.

Hopefully, these tips will help you eat less and attain a healthier weight next year than you did this year. However, these 8 tips are just the tip of the iceberg. If this article has piqued your interest and you’d like to learn more, I recommend you read one of Dr. Wansink’s books.

Finally, for best results I recommend that you also:

  • Make healthier food choices.
    • Whole unprocessed or minimally processed foods have a lower caloric density than the highly processed foods most of us eat.
    • People eating whole food, primarily plant-based diets generally weigh less than people eating the typical American diet or meat-based low carb diets.
    • Don’t overwhelm yourself. Simply substitute one healthy food choice for one unhealthy food choice every week or so. There are no “rules”. You choose which substitutions you want to make and how often you want to make them.
  • Exercise more.
    • Just don’t call it exercise. If you look forward to your sport, dance, etc., you are more likely to keep doing it.

The Bottom Line

If you are like most people. You want to lose weight but dread going on another diet. What if you could lose weight without going on a diet? What if you could learn just a few tricks that would help you eat less every day?

  • Brian Wansink’s research has shown that overeating, to a large extent, is mindlessly dependent on external eating cues, and that you can’t necessarily avoid being influenced by those external clues even if you are intelligent and motivated!
  • I have distilled his research into 8 simple tips to help you eat less and attain a healthier weight next year than you did this year.

Which Diet Is Best?

Tips For Loosing Weight And Keeping It Off

Author: Dr. Stephen Chaney

Diet season starts in just a few days! Like millions of Americans, you will probably be setting a goal to eat healthier, lose weight, or both. But which diet is best? Vegan, Paleo, Keto, 360, Intermittent Fasting, low-carb, low fat – the list is endless.

And then there are the commercial diets: Meal replacements, low calorie processed foods, prepared meals delivered to your door – just to name a few of the categories.

You can choose to count calories, focus on portion sizes, or keep a food journal.

And, if you really want to live dangerously, you can try the latest diet pills that claim to curb your appetite and rev up your metabolism.

The advertisements for all these diets sound so convincing. They give you scientific-sounding mumbo-jumbo to explain why they work. Then they talk about clinical studies they say prove their diet works.

If you are like most Americans, you have already tried several of these diets. They worked for a while, but the pounds came back – and brought their friends with them.

But, as the saying goes, “Hope springs eternal in the human breast. Surely some diet you haven’t tried yet will work for you.

There are such diets. But they will require effort. They will require a change of mindset. There is no magic wand that will chase the extra pounds away forever.

If you are searching for the perfect diet to start the new year, let me be your guide. Here are:

  • 4 tips on what to avoid and…
  • 6 tips on what to look for…

…when you are choosing the best diet for you.

What Should You Avoid When Choosing The Best Diet?

AvoidEndorsements.

Endorsements by your favorite athlete or public person are paid for. They don’t necessarily represent their opinion. Nor do they assure you that they follow that diet or use that diet supplement.

Endorsements by Dr. Strangelove and his buddies can be equally misleading. They usually tell you that the medical establishment has been lying to you, and they have discovered the “secret” to permanent weight loss and the “Fountain of Youth”.

Recommendations of the medical and scientific communities usually represent a consensus statement by the top experts in their field. I would choose their advice over Dr. Strangelove’s opinion any day.

2) Testimonials

Most of the testimonials you see online or in print are either paid for or are fake.

Testimonials by your friends can be equally misleading. We are all different. What works for your friend or your trainer may not work for you.

For example, some of us do better on low-carb diets, and others do better on low fat diets.

[Note: Some DNA testing companies claim they can sequence your DNA and tell you which diet is best. However, as I reported in a recent article in “Health Tips From The Professor”, independent studies show that DNA testing is of no use in predicting whether low-carb or low-fat diets are better for you.]

3) Diets Based on “Magic” Or “Forbidden” Foods or Food Groups.

I have often said we have 5 food groups for a reason. Each food group provides a unique blend of nutrients and phytonutrients. And each plant food group provides a unique blend of fibers that support the growth of different types of friendly gut bacteria.

The bottom line is that each of us does better with some foods than others, but there are no “magic” or “forbidden” foods that apply to everyone.

4) “Magic” Diets.

MagicI have written perhaps the first diet book, “Slaying The Food Myths”, that doesn’t feature a “magic” diet that is going to make the pounds melt away and allow you to live to 100. Instead, I recommend a variety of healthy diets and suggest you choose the one that fits you best.

However, I understand the allure of “magic” diets. Dr. Strangelove claims the diet will be effortless. He gives you some scientific-sounding mumbo-jumbo to convince you the diet is scientifically sound. Then he cites some clinical studies showing the diet will cause you to lose weight and will improve your health parameters (things like cholesterol, triglycerides, blood sugar, and blood pressure). It sounds so convincing.

Before you fall for Dr. Strangelove’s latest “magic” diet, let me share two things that may blow your mind:

    • The studies are all short-term (usually 3 months or less).
    • When you rely on short-term studies, the very low-fat Vegan diet and very low-carb Keto diet give you virtually identical weight loss and improvement in health parameters!

Those two diets are as different as any two diets could be. That means we can forget all the scientific-sounding mumbo-jumbo as to why each of those diets work. Instead, we should ask what these two diets have in common.

The answer is simple:

#1: The clinical studies are comparing “magic” diets to the typical American diet. Anything is better than the typical American diet! It is high in sugar, refined carbohydrates, saturated fat, and highly processed foods. No wonder the “magic” diets look so good.

#2: The diets are whole food diets. Anytime you eliminate sodas, fast foods, and highly processed foods, you will lose weight.

#3: The diets eliminate one or more food groups. Whenever you eliminate some of your favorite foods from your diet, you tend to lose weight without thinking about it. I call this the cream cheese and bagel phenomenon.

    • If you are following a low-fat diet, it sounds great to say you can eat all the bagels you want. But without cream cheese to go with the bagels, you tend to eat fewer bagels.
    • If you are following a low-carb diet, it sounds great to say you can eat as much cream cheese as you want, but without bagels to go with your cream cheese, you tend to eat less cream cheese.

#4: Because they eliminate many of your favorite foods, “magic” diets make you focus on what you eat. Whenever you focus on what you eat, you tend to lose weight. That is why food journals and calorie counters are effective.

#5: Finally, whenever you lose weight, your health parameters (cholesterol, triglycerides, blood sugar, and blood pressure) improve.

What Should You Look For In Choosing The Best Diet?

Skeptic1) Choose whole food diets. Avoid sodas, fast foods, and highly processed foods.

2) Choose primarily plant-based diets. These can range from Vegan through semi-vegetarian, Mediterranean, DASH, and Nordic. All are healthy diets. I have discussed the evidence for this recommendation in my book “Slaying The Food Myths”. Here is a brief summary.

When we look at long term (10-20 year) studies:

    • Vegetarians weigh less and are healthier than people consuming the typical American diet.
    • People consuming semi-vegetarian, Mediterranean, and DASH diets are healthier than people consuming the typical American diet.

If you look at low-carb diets:

    • People consuming plant-based low-carb diets weigh less and are healthier than people consuming the typical American diet.
    • People consuming meat-based low-carb diets are just as fat and unhealthy as people consuming the typical American diet.
    • The Atkins low-carb diet has been around for more than 50 years, and there is no evidence it is healthy long-term.

3) Choose diets that include a variety of foods from all 5 food groups. I have discussed the rationale for that recommendation above.

4) Choose diets that consider meat as a garnish, not a main course.

5) Choose diets that feature healthy carbs and healthy fats rather than low-carb or low-fat diets.

6) Think lifestyle, not diet. If you choose a restrictive diet so you can achieve quick weight loss, you will probably be just as fat and unhealthy next December 31st as you are this year. Instead, choose diets that teach healthy eating and lifestyle changes that you can make a permanent part of your life.

Tips For Losing Weight And Keeping It Off

You know the brutal truth. Around 95% of dieters regain everything they lost and then some within a few years. You have probably gone through one or more cycles of weight loss and regain yourself – something called “yo-yo dieting”. You may even be asking yourself if it is worth bothering to try to lose weight this year.

Rather focusing on the negative statistics of weight loss, let’s look at the good news. There are people who lose the weight and keep it off. What do they do?

There is an organization called the National Weight Control Registry that has enrolled more than 10,000 people who have lost weight and kept it off. The people in this group lost weight on almost every diet imaginable. However, here is the important statistic: On average people in this group have lost 66 pounds and kept it off for 5 years.

The National Weight Control Registry has kept track of what they have done to keep the weight off. Here is what they do that you may not be doing:

  1. They consume a reduced calorie, low fat diet.

2) They get lots of exercise (around 1 hour/day).

3) They have internalized their eating patterns. In short, this is no longer a diet. It has become a permanent part of their lifestyle. This is the way they eat without even thinking about it.

4) They monitor their weight regularly. When they gain a few pounds, they modify their diet until they are back at their target weight.

5) They eat breakfast on a regular basis.

6) They watch less than 10 hours of TV/week.

7) They are consistent (no planned cheat days).

Which Diet Is Best?

Now it is time to get back to the question you are asking right now, “Which diet is best?” I have covered a lot of ground in this article. Let me summarize it for you.

If you are thinking about popular diets:

  • Primarily plant-based diets ranging from Vegan to Mediterranean and Dash are associated with a healthier weight and better health long term.
    • If want to lose weight quickly, you may want to start with the more restrictive plant-based diets, like Vegan, Ornish, Pritikin or semi-vegetarian.
    • If you do better with a low-carb diet, my recommendation is the low-carb version of the Mediterranean diet.
    • If your primary goal is rapid weight loss, you could also start with one of the healthier of the restrictive low-carb diets, like the Paleo or the 360 diet. I do not recommend the Keto diet.
  • No matter what diet you start with, plan to transition to the primarily plant-based diet that best fits your lifestyle and food preferences. This is the diet you will want to stick with to maintain your weight loss and achieve better health long term.
  • Plan on permanent lifestyle change rather than a short-term diet. Otherwise, you are just wasting your time.
  • Eat whole foods. Big Food keeps up with America’s favorite diets and is only too happy to sell you highly processed foods that match your favorite diet. Avoid those like the plague.

If you are thinking about commercial diets featuring meal replacement products:

  • Look for meal replacement products that:
    • Do not contain artificial sweeteners, flavors, or preservatives.
    • Use non-GMO protein. A non-GMO certification for the other ingredients is not necessary. For a more detailed explanation of when non-GMO certification is important and when it is unnecessary, see my article) in “Health Tips From the Professor”.
    • Have stringent quality controls in place to assure purity. “Organic” and/or “non-GMO” on the label do not assure purity.
  • Look for programs that can provide clinical studies showing their diet plan is effective for weight loss and for keeping the weight off. Many programs have short-term clinical studies showing they are effective for weight loss, but very few have longer-term studies showing the weight stays off.
  • Finally, look for programs that teach permanent lifestyle change. This should include guidance on exercise and healthy eating.

I do not recommend most commercial diets that feature prepared low-calorie foods “shipped right to your door” as a major part of their program. The foods are highly processed. Plus, they include all your favorite unhealthy foods as part of the program. Even if they include lifestyle change as part of their program, they are undermining their message with the foods they are providing you.

I would be remiss if I didn’t mention that Weight Watchers is highly recommended by most experts in the field. Weight Watchers emphasizes journaling and counting calories, which is a plus because it makes you focus on what you are eating. They also have a good lifestyle program and support that can help you transition to permanent lifestyle change if you are willing to put in the effort. However, I don’t recommend their prepared low-calorie foods. They are no better than foods provided by the other commercial diet programs.

The Bottom Line 

Weight loss season is upon us. If you plan to lose weight and/or adopt a healthier diet in the coming year, you are probably asking, “Which Diet Is Best?” In this issue of “Health Tips From The Professor” I give you:

  • 4 tips on what to avoid when selecting the diet that is best for you.
  • 6 tips on how to choose the best diet.
  • 5 tips on what to look for when selecting a diet featuring meal replacement products.
  • 7 tips on how to keep the weight off.

Then I put all this information together to help you choose the best diet, the best meal replacement product, and/or the best commercial diet program.

Can Vegans Have Strong Bones?

When Is Supplementation Important? 

Author: Dr. Stephen Chaney

Healthy BoneWhole food, vegan diets are incredibly healthy.

  • They have a low caloric density, which can help you maintain a healthy weight.
  • They are anti-inflammatory, which can help prevent all the “itis” diseases.
  • They are associated with reduced risk of diabetes, heart disease, and some cancers.
  • Plus a recent study has shown that vegans age 60 and older require 58% fewer medications than people consuming non-vegetarian diets.

But vegan diets are incomplete, and as I have said previously, “We have 5 food groups for a reason”. Vegan diets tend to be low in several important nutrients, but for the purposes of this article I will focus on calcium and vitamin D. Vitamin D is a particular problem for vegans because mushrooms are the only plant food that naturally contain vitamin D, and the vitamin D found in mushrooms is in the less potent D2 form.

Calcium and vitamin D are essential for strong bones, so it is not surprising that vegans tend to have less dense bones than non-vegans. But are these differences significant? Are vegans more likely to have broken bones than non-vegans?

That is the question the current study (DL Thorpe et al, American Journal of Clinical Nutrition, 114: 488-495, 2021) was designed to answer. The study also asked whether supplementation with calcium and vitamin D was sufficient to reduce the risk of bone fracture in vegans.

How Was This Study Done?

Clinical StudyThe data for this study were obtained from the Adventist Health Study-2. This is a study of ~96,000 members of the Seventh-day Adventist Church in North America who were recruited into the study between 2002 and 2007 and followed for up to 15 years.

Seventh-day Adventists are a good group for this kind of study because the Adventist church advocates a vegan diet consisting of legumes, whole grains, nuts, fruits, and vegetables. However, it allows personal choice, so a significant number of Adventists choose modifications of the vegan diet and 42% of them eat a nonvegetarian diet.

This diversity allows studies of the Adventist population to not only compare a vegan diet to a nonvegetarian diet, but also to compare it with the various forms of vegetarian diets.

This study was designed to determine whether vegans had a higher risk of hip fractures than non-vegan Adventists. It was performed with a sub-population of the original study group who were over 45 years old at the time of enrollment and who were white, non-Hispanic. The decision to focus on the white non-Hispanic group was made because this is the group with the highest risk of hip fractures after age 45.

At enrollment into the study all participants completed a comprehensive lifestyle questionnaire which included a detail food frequency questionnaire. Based on the food frequency questionnaire participants were divided into 5 dietary patterns.

  • Vegans (consume only a plant-based diet).
  • Lacto-ovo-vegetarian (include dairy and eggs in their diet).
  • Pesco-vegetarians (include fish as well as dairy and eggs in their diet).
  • Semi-vegetarians (include fish and some non-fish meat (primarily poultry) as well as dairy and eggs in their diet).
  • Non-vegetarians (include all meats, dairy, and eggs in their diet). Their diet included 58% plant protein, which is much higher than the typical American diet, but much less than the 96% plant protein consumed by vegans.

Every two years the participants were mailed follow-up questionnaires that included the question, “Have you had any fractures (broken bones) of the wrist or hip after 2001? Include only those that came from a fall or minor accident.”

Can Vegans Have Strong Bones?

Unhealthy BoneThe results of this study were striking.

  • When men and women were considered together there was an increasing risk of hip fracture with increasing plant-based diet patterns. But the differences were not statistically significant.
  • However, the effect of diet pattern on the risk of hip fractures was strongly influenced by gender.
    • For men there was no association between diet pattern and risk of hip fractures.
    • For women there was an increased risk of hip fractures across the diet continuum from nonvegetarians to vegans, with vegan women having a 55% higher risk of hip fracture than nonvegetarian women.
  • The increased risk of hip fractures in vegan women did not appear to be due to other lifestyle differences between vegan women and nonvegetarian women. For example:
    • Vegan women were almost twice as likely to walk more than 5 miles/week than nonvegetarian women.
    • Vegan women consumed more vitamin C and magnesium, which are also important for strong bones, than nonvegetarian women.
    • Vegan women got the same amount of daily sun exposure as nonvegetarian women.
  • The effect of diet pattern on the risk of hip fractures was also strongly influenced by supplementation with Calcium Supplementcalcium and vitamin D.
    • Vegan women who did not supplement with calcium and vitamin D had a 3-fold higher risk of hip fracture than nonvegetarian women who did not supplement.
    • Vegan women who supplemented with calcium and vitamin D (660 mg/day of calcium and 13.5 mcg/day of vitamin D on average) had no increased risk of hip fracture compared to nonvegetarian women who supplemented with calcium and vitamin D.
  • In interpreting this study there are a few things we should note.
    • The authors attributed the lack of an effect of a vegan diet on hip fracture risk in men to anatomical and hormonal differences that result in higher bone density for males.
    • In addition, because the average age of onset of osteoporosis is 15 years later for men than for women, this study may not have been adequately designed to measure the effect of a vegan diet on hip fracture in men. Ideally, the study should have enrolled participants who were at least 60 or older if it wished to detect an effect of diet on hip fractures in men.
    • Finally, because the study enrolled only white, non-Hispanic women into the study, it does not tell us the effect of a vegan diet on women of other ethnicities. Once again, if there is an effect, it would likely occur at an older age than for white, non-Hispanic women.

The authors concluded, “Without combined supplementation of both vitamin D and calcium, female vegans are at high risk of hip fracture. However, with supplementation the excessive risk associated with vegans disappeared.”

Simply put, vegan diets are very healthy. They reduce the risk of heart disease, high blood pressure, diabetes, some cancers, and inflammatory diseases.

However, the bad news is:

  • Vegan women have a lower intake of both calcium and vitamin D than nonvegetarian women.
  • Vegan women have lower bone density than nonvegetarian women.
  • Vegan women have a higher risk of hip fracture than nonvegetarian women.

The good news is:

  • Supplement with calcium and vitamin D eliminates the increased risk of hip fracture for vegan women compared to nonvegetarian women.

When Is Supplementation Important?

Supplementation PerspectiveMuch of the controversy about supplementation comes from a “one size fits all” mentality. Supplement proponents are constantly proclaiming that everyone needs nutrient “X”. And scientists are constantly proving that everyone doesn’t need nutrient “X”. No wonder you are confused.

I believe in a more holistic approach for determining whether certain supplements are right for you. Dietary insufficiencies, increased need, genetic predisposition, and diseases all affect your need for supplementation, as illustrated in the diagram on your left. I have discussed this approach in more detail in a previous issue (https://www.chaneyhealth.com/healthtips/do-you-need-supplements/) of “Health Tips From the Professor”.

But today I will just focus on dietary insufficiencies.

  • Most Americans consume too much highly processed fast and convenience foods. According to the USDA, we are often getting inadequate amounts of calcium, magnesium, and vitamins A, D, E and C. Iron is also considered a nutrient of concern for young children and pregnant women.
  • According to a recent study, regular use of a multivitamin is sufficient to eliminate most these deficiencies except for calcium, magnesium, and vitamin D. A well-designed calcium, magnesium and vitamin D supplement may be needed to eliminate those deficiencies.
  • In addition, intake of omega-3 fatty acids from foods appears to be inadequate in this country. Recent studies have found that American’s blood levels of omega-3s are among the lowest in the world and only half of the recommended level for reducing the risk of heart disease. Therefore, omega-3 supplementation is often a good idea.

Ironically, “healthy” diets are not much better when it comes to dietary insufficiencies. That is because many of these diets eliminate one or more food groups. And, as I have said previously, we have 5 food groups for a reason.

Take the vegan diet, for example:

  • There is excellent evidence that whole food, vegan diets reduce the risk of heart disease, diabetes, inflammatory diseases, and some cancers. It qualifies as an incredibly healthy diet.
  • However, vegan diets exclude dairy and meats. They are often low in protein, vitamin B12, vitamin D, calcium, iron, zinc, and long chain omega-3 fatty acids. Supplementation with these nutrients is a good idea for people following a vegan diet.
  • The study described above goes one step further. It shows that supplementation with calcium and vitamin D may be essential for reducing the risk of hip fractures in vegan women.

There are other popular diets like Paleo and keto which claim to be healthy even though there are no long-term studies to back up that claim.

  • However, those diets are also incomplete. They exclude fruits, some vegetables, grains, and most plant protein sources.
  • A recent study reported that the Paleo diet increased the risk of calcium, magnesium, iodine, thiamin, riboflavin, folate, and vitamin D deficiency. The keto diet is even more restrictive and is likely to create additional deficiencies.
  • And it is not just nutrient deficiencies that are of concern when you eliminate plant food groups. Plants also provide a variety of phytonutrients that are important for optimal health and fiber that supports the growth of beneficial gut bacteria.

In short, the typical American diet has nutrient insufficiencies. “Healthy” diets that eliminate food groups also create nutrient insufficiencies. Supplementation can fill those gaps.

The Bottom Line

Vegan diets are incredibly healthy, but:

  • They eliminate two food groups – dairy, and meat protein.
  • They have lower calcium and vitamin D intake than nonvegetarians.
  • They also have lower bone density than nonvegetarians.

The study described in this article was designed to determine whether vegans also had a higher risk of bone fractures. It found:

  • Vegan women who don’t supplement have a 3-fold higher risk of hip fracture than nonvegetarian women.
  • The increased risk of hip fractures in vegan women did not appear to be due to other lifestyle differences between vegan women and nonvegetarian women.
  • Supplementation with calcium and vitamin D (660 mg/day of calcium and 13.5 mcg/day of vitamin D on average) eliminated the difference in risk of hip fracture between vegan women and nonvegetarian women.

In the article above I discuss the importance of supplementation in assuring diets are nutritionally complete.

  • In short, the typical American diet has nutrient insufficiencies. “Healthy” diets that eliminate food groups also create nutrient insufficiencies. Supplementation can fill those gaps.

For more details about the study and a discussion of which supplements may be needed to assure nutritionally adequate diets, read the article above.

Is Dairy Bad For Your Heart?

Is Dairy Right For You? 

Author: Dr. Stephen Chaney

dairy foodsWe have been told for years that dairy foods are good for us. They are part of the USDA five food groups. In fact, they are part of the dietary recommendations of every government and most health organizations across the world.

And dairy foods are nutritious. They are excellent sources of calcium, potassium, protein, and vitamins A and B12. And if they are fortified, they are also an excellent source of vitamin D. Many health experts consider them essential for healthy bones. So, you might be saying, “Case closed. We should all be eating more dairy foods”.

But, not so fast. Many dairy foods are high in saturated fats. In fact, 65% of the fat in dairy foods is saturated. We have known for years that when saturated fats replace polyunsaturated fats in the diet, LDL cholesterol levels increase. And, as I reported in a previous issue of “Health Tips From the Professor” there is excellent evidence that replacing polyunsaturated fats with saturated fats substantially increases the risk of dying from heart attack, stroke, and other forms of heart disease.

The widely accepted message from these studies is that saturated fats raise LDL cholesterol levels and increases our risk of dying from heart disease. If we accept this message, it poses a dilemma. Dairy foods are nutritious. But they are high in saturated fat. What should we do?

The answer from the American Heart Association and most other health organizations is simple. We should eat low-fat dairy foods.

But this is where it gets really confusing. Dairy foods are composed of much more than saturated fats. And you have probably seen the claims that full fat dairy foods don’t increase the risk of heart disease.

So, what is the truth about full-fat dairy foods and heart health? In this issue of “Health Tips From The Professor” I review three recent studies and the recommendations of the Heart Foundation because they shed light on this question.

Is Dairy Bad For Your Heart?

dairy products and heart disease cheeseBefore I answer this question, I should point out that there are two ways of looking at it.

  • As I said above, the studies proving that saturated fats increase the risk of heart disease, substituted saturated fats for polyunsaturated fats and controlled every other aspect of the diet. That has led the American Heart Association and other organizations to recommend that we eat low-fat dairy foods.
  • However, when most people hear that recommendation, they simply substitute low-fat dairy for full-fat dairy foods without changing any other aspect of their diet or lifestyle. The first two studies were designed to see if that approach was effective for reducing heart disease risk.

The first study (KA Schmidt et al, American Journal of Clinical Nutrition, 114: 882-892, 2021) was a randomized controlled trial that compared the effect of low-fat dairy foods and full-fat dairy foods on heart health parameters.

The participants in this study were:

  • Average age = 62
  • 56% male
  • 75% white
  • Average weight = 214 pounds
  • All of them were prediabetic

All participants were told to stick with their usual diets (probably typical American diets) except for the amount and type of dairy foods added to their diet. During the first four weeks they restricted dairy consumption to 3 servings of nonfat dairy/week so they would all be starting with the same amount of dairy consumption. Then they were divided into 3 groups for the 12-week study:

  • Group 1 continued with 3 servings of nonfat dairy/week.
  • Group 2 added 3 servings of low-fat dairy/day to their usual diet.
  • Group 3 added 3 servings of high-fat dairy/day to their usual diet.

At the beginning of the study and again at the end of the 12-week study LDL cholesterol, HDL cholesterol, triglycerides, free fatty acids, and blood pressure were measured. The results were:

  • There was no difference in LDL cholesterol, HDL cholesterol, triglycerides, free fatty acids, or blood pressure in the three groups at the end of 12 weeks.
  • There was no also significant change in LDL cholesterol, HDL cholesterol, triglycerides, free fatty acids, or blood pressure during the study in any of the three groups.

The authors concluded, “A diet rich in full-fat dairy had no effect on fasting lipid profile or blood pressure compared with diets limited in dairy or rich in low-fat dairy. Therefore, dairy fat, when consumed as part of complex whole foods does not adversely affect these classic cardiovascular disease risk factors.”

[Note: The last sentence is key. Remember the “proof” that saturated fats increase LDL levels and increase the risk of heart disease come from studies in which saturated fats were substituted for polyunsaturated fats and every other aspect of the diet was carefully controlled.

In this study, and others like it, the effects of saturated fats are studied in a complex food (dairy) in the presence of an even more complex diet containing many foods that influence the risk of heart disease.]

The second study (J Guo et al, European Journal of Epidemiology 32: 269-287, 2017) was a meta-analysis of Healthy Heart29 studies with 938,465 participants looking at the association of full-fat dairy consumption with the risk of dying from heart disease.

Seven of the 29 studies were conducted in the United States. Of the remaining studies 3 were from Japan and Taiwan, 2 were from Australia, and 17 were from Europe.

The results of the study were:

  • There was no association between full-fat dairy, low-fat dairy, and total dairy consumption and risk of dying from heart disease.

When the results were broken down into individual dairy foods.

  • There was no association between milk consumption and risk of dying from heart disease.
  • Consumption of one serving/day of fermented dairy foods was associated with a 2% decreased risk of dying from heart disease.

The authors concluded, “The current meta-analysis of 29 prospective cohort studies suggested no association of total, high and low-fat dairy and milk with risk of cardiovascular disease. In addition, a possible role of fermented dairy was found in cardiovascular disease prevention, but the result was driven by a single study.” [I would add that this effect, if confirmed by subsequent studies, is extremely small (2%).]

The first two studies do not say that full-fat dairy foods are heart healthy for everyone, as some headlines would have you believe. Instead, these studies show fairly convincingly that simply switching from full-fat to low-fat dairy foods, without changing any other aspect of your diet and lifestyle, is not as effective at decreasing your risk of heart disease as some experts would have you believe.

balance scaleThe third publication (WC Willett and DS Ludwig, New England Journal of Medicine 382: 644-654, 2020) was a review of the effect of dairy foods on our health. One of the authors, Walter C Willett, is one of the top experts in the field. The review covered many topics, but I will focus on the section dealing with the effect of dairy foods on heart health.

This review took a more nuanced look at full-fat dairy foods and examined the effect of substituting full-fat dairy for other protein foods.

The review concludes, “The association of milk with the risk of cardiovascular disease depends on the comparison foods. In most cohort studies [such as the studies described above], no specific comparison was made; by default, the comparison was everything else in the diet – typically large amounts of refined grains, potato products, sugar, and meat.”

The review went on to say that previous studies have shown:

  • “Both full-fat and low-fat dairy foods…were associated with a lower risk [of cardiovascular disease and stroke] than…the same number of servings of red meat but with a higher risk than seen with the same number of servings of fish or nuts.”
  • “Dairy fat…was associated with a higher risk of cardiovascular disease than was polyunsaturated or vegetable fat.”
  • “For persons living in low-income countries where diets are very high in starch, moderate intake of dairy foods may reduce cardiovascular disease by providing nutritional value and reducing glycemic load [the amount of easily digestible carbohydrate in the diet].”

Is Dairy Right For You?

dairy products and heart disease questionsNow I am ready to answer the question posed at the beginning of this article, “Is dairy bad for your heart?” The answer is, “It depends”.

  • As described above, the effect of dairy on heart health depends on our overall diet. It also depends on our lifestyle, our weight, and our health.
  • In addition, clinical studies report averages, and none of us are average. We all have unique diets, lifestyles, health status, and genetic makeup.

So, what does this mean for you? Perhaps it is best summed up by the recommendations of Australia’s Heart Foundation which take health status, lifestyle, and genetic differences into account:

  • A heart healthy diet can include dairy, but it is not essential [with careful planning and/or supplementation you can get your calcium and protein elsewhere].
  • Milk, yogurt, and cheese are considered neutral for heart health, meaning they neither increase nor decrease the risk of heart disease for the average person. However, the recommendations vary depending on health status, genetics, and lifestyle:
    • Low-fat milk, yogurt, and cheese are recommended for people with heart disease or high cholesterol because the fat in dairy foods can raise cholesterol more for these people. [Note: If cholesterol is elevated, it usually means that individual has a hard time regulating blood cholesterol levels because of obesity, genetics, or pre-existing disease. For these individuals, diets high in saturated fat are more likely to increase LDL cholesterol and risk of heart disease.]
    • Full-fat milk, yogurt, and cheese can be part of a heart healthy diet for healthy people provided most of the fat in the diet comes from fish, nuts, seeds, and healthy oils. [Note: Overall diet is important.]
  • Choosing unflavored milk, yogurt, and cheese helps limit the amount of sugar in your diet.
  • Ice cream, cream, and dairy desserts should be eaten only sometimes and in small amounts because they have more sugar and fat, and less protein, vitamins, and minerals than other dairy foods.
  • Butter raises LDL cholesterol levels, especially in people who already have elevated cholesterol.
    • There is no evidence that butter can be part of a heart healthy diet, so you should consider healthier options such as olive oil, avocado, nut butters, and spreads made with healthier oils, such as olive oil.

The Bottom Line

We have been told for years that dairy foods are good for us. They are part of the USDA five food groups. In fact, they are part of the dietary recommendations of every government and most health organizations across the world.

However, dairy foods have been controversial in recent years. Some experts claim that only low-fat dairy products can be heart healthy. Others claim that full-fat dairy foods are just as healthy as low-fat dairy foods.

I shared three recent publications and dietary recommendations from The Heart Foundation that shed light on these controversies.

The first study found that full-fat dairy foods did not increase LDL cholesterol, triglycerides, and other heart disease risk factors.

The second study was a meta-analysis of 29 clinical studies with almost one million people. It found that full-fat dairy foods did not increase the risk of dying from heart disease.

“Case closed”, you might say. However, these studies do not say that full-fat dairy foods are heart healthy for everyone, as some headlines would have you believe. Instead, these studies show fairly convincingly that simply switching from full-fat to low-fat dairy foods, without changing any other aspect of your diet and lifestyle, is not as effective at decreasing your risk of heart disease as some experts would have you believe.

Moreover, these studies do not account for the effect of overall diet, lifestyle, health status, and genetics on the risk of heart disease.

That is why I included the third study in my review. It took the overall diet into account and concluded the effect of full-fat dairy foods on heart disease risk depends on the overall diet.

  • For some diets full-fat dairy increases heart disease risk.
  • For other diets full-fat dairy has no effect on heart disease risk.
  • And for some diets full-fat dairy may even decrease heart disease risk.

Finally, I included recommendations of the Australian Heart Foundation because they included the effect of health status, lifestyle, and genetics in their recommendations.
