Healthy HeartWhile February is the shortest month of the year, to our northern family and friends it is the longest, seemingly endless, month.

Where I live in Sarasota Florida, winter brings us near-perfect days and cooler nights.  It’s my favorite time of year.  And of course, we all celebrate the holiday of love – Valentine’s Day!

Just a bit of trivia: In 1868, Richard Cadbury released the first Valentine’s Day box of chocolates, followed in 1902 with the first conversation hearts from the New England Confectionery Company. In the 1840s, Esther A. Howland created the first commercial Valentine’s Day cards in the United States. Hallmark first offered Valentine’s Day cards in 1913 and began producing them in 1916.  (Thanks to Wikipedia for all this interesting info).

What Is A Meniscus?

One of my clients asked me to talk about a medial meniscus tear, and that is a topic that is “near and dear to me” because I had a severed medial meniscus from a ski accident.

The meniscus is something that many people aren’t familiar with, unless they have had a meniscus tear, then you definitely know all about it.  It hurts!

All of the major joints are complicated with many ligaments and other structures, each having an important function.

The knee joint is straightforward.

The lateral (outside of knee joint) and medial (inside of knee joint) meniscus cushion the femur (thigh) bone and tibia (shin bone) so your knee can bend and straighten without wearing down the bone.

Ligaments that surround the knee joint hold the bones together and form a tight, secure joint.

How Does A Meniscus Tear?

MeniscusTrauma to the knee joint, especially a twisting movement, will tear the meniscus.

In 1995 I had a ski accident where I severed the medial meniscus, but I didn’t have insurance at the time. I paid the $1000 for an MRI to find out why my knee was in so much pain, and why my knee felt like it was going to totally separate.

It turned out that I not only severed my left medial meniscus, I also tore my anterior cruciate ligament (ACL), The ACL holds your bones together from front to back. When this tore, I felt like whenever stepped down my upper leg still kept going forward.  It was a scary feeling, I felt like my leg was going to come apart at my knee. Yikes!

Recovering From A Meniscus Tear

I need to remind you that I am not a doctor, nor do I have medical training to advise you about what to do.  This message isn’t meant to replace your physician’s advice. 

When I found myself with a severed medial meniscus and a torn ACL, and I didn’t have medical insurance, I didn’t know what to do!  Fortunately, I was working along with Zev Cohen, MD.  My therapy practice was in Dr Cohen’s office, and he would often ask me to see one of his patients who were in pain when he knew it wasn’t caused by any systemic or visceral problems.  I totally respected Dr. Cohen because he truly wanted his patients to get better, even if it meant he was going to bring in a massage therapist!

As a result, when Dr. Cohen told me that my meniscus would heal with scar tissue, I believed him. And it worked!  The only glitch was the scar tissue made my knee stiff, so I started to do a movement that I believed would stretch the scar tissue enough so I could bend my knee properly. And that worked too!

A Stretch for AFTER Your Meniscus Heals 

Caution: Do Not do this stretch until your knee is completely healed. 

Stand with your feet directly under your hips. Hold on to a closed door, being sure you’re on the side of the door that pushes out, so you are pulling it shut as you do the stretch.

While keeping your knees straight up from your ankle, squat down, stopping when you start to feel pain in your knee.  Stay there, and then go just a little bit further.  Don’t push, it’s better to go slowly so your muscles stretch safely.  Scar tissue is really dense, it doesn’t stretch easily (if at all) so you need to slowly allow the scar tissue to loosen.

I can’t guarantee that this will work for you but let me tell you what happened to me.  I was doing this stretch multiple times a day, stopping when it would be too painful – or when I just ran out of time. Then one day – success!

One day I was squatting down and suddenly something released, and I ended up sitting on the floor with my knees totally bent!

Since then, I’ve been able to get back to skiing, and I have ZERO pain!

Wishing you well,

Which Diet Should You Choose?

Author: Dr. Stephen Chaney

Emoticon-BadMany of you started 2023 with goals of losing weight and/or improving your health. In many cases, that involved choosing a new diet. That was only 6 weeks 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 2023”. For the full report, click on this link.

How Was This Report Created?

Expert PanelUS News & World Report recruited a panel of 30 nationally recognized experts in diet, nutrition, obesity, food psychology, diabetes, and heart disease to review the 24 most popular diets.

The diets evaluated are not the same each year. Last year they evaluated the top 40 most popular diets. This year they only reviewed the top 24.

That means some good diets were left off the list. For example, the vegan diet is very healthy, but it is also very restrictive. Very few people follow a pure vegan diet, so it didn’t make the top 24 most popular. However, this year’s list did include several primarily plant-based diets that are more popular with the general public.

The panel is also 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 eleven sets of Best Diets rankings:

  • Best Diets Overall ranks diets on several different parameters, including whether all food groups are included in the diet, the availability of the foods needed to be on the diet and the use of additional vitamins or supplements. They considered if the diet was evidence-based and adaptable to meet cultural, religious, or other personal preferences. In addition, the criteria also included evaluation of the prep and planning time required for the diet and the effectiveness of the diet for someone who wants to get and stay healthy.
  • Best Plant-Based Diets used the same approach as Best Diets Overall to rank the eight plans emphasizing minimally processed foods from plants that were included in this year’s ratings.
  • Best Commercial Diet ratings used the same approach to rank 15 commercial diet programs that require a participation fee or promote the use of branded food or nutritional products.
  • Best Long-Term Weight-Loss Diet ratings were generated by combining the safety of the rate of weight loss promoted and the likelihood of the plan to result in successful long-term weight loss and maintenance of weight loss.
  • Best Fast Weight-Loss Diets were scored on their effectiveness for someone who wants to lose weight in three months or less.
  • Best Diabetes Diet ratings were calculated equally from the effectiveness of the diet for someone who wants to lower risk factors for diabetes, the nutritional quality of the diet, and research evidence-based support for the diet.
  • Best Heart-Healthy Diet ratings were calculated equally from the effectiveness of the diet for someone who wants to lower risk factors for hypertension and other forms of heart disease, the nutritional quality of the diet, and evidence-based support for the diet.
  • Best Diets for Bone and Joint Health were calculated equally on the effectiveness of the diet for someone who wants to lower their risk factors for inflammation and improve bone and joint health, as well as the nutritional quality and research evidence-based support for the diet.
  • 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 scores for the relevant lifestyle questions, including whether all food groups are included and if the recommended foods are readily available at the average supermarket.
  • Best Family-Friendly Diets were calculated equally on their adaptability for the whole family, including cultural, religious, and personal preferences, the time required to plan and prep, nutritional value and access to food at any supermarket.

Which Diets Are Best In 2023?

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 3 and bottom 3 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. (I have a brief discussion of commercial diets below). If you notice a number missing in my summaries, it is because I eliminated one or more commercial diet from my summary.]

Best Diets Overall 

The Top 3: 

#1: Mediterranean Diet. The Mediterranean diet has been ranked #1 for 6 consecutive years.

#2 (tie): Flexitarian Diet (A flexible semi-vegetarian diet).

The Bottom 3: 

#20: Keto Diet (A high protein, high fat, very low carb diet designed to achieve ketosis).

#21: Atkins Diet (The granddaddy of the high animal protein, low carb, high fat diets).

Which Diets Are Best For Rapid Weight Loss?

Happy woman on scaleThere are 2 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.
    • Last year’s diet analysis included the vegan diet, and both vegan and keto diets ranked near the top of the rapid weight loss category. Keto and vegan diets are both very restrictive, but they are polar opposites in terms of the foods they allow and restrict.
      • The keto diet is a meat heavy, very low carb diet. It restricts fruits, some vegetables, grains, and most legumes.
      • The vegan diet is a very low-fat diet that eliminates meat, dairy, eggs, and animal fats.
    • The Atkins and keto diets toppled this year’s rapid weight loss list, but they were joined by the Mayo Clinic, South Beach, and volumetrics diets. Those diets are also restrictive, but, like the vegan diet, they are very different from the Atkins and keto diets.
    • I did not include commercial diets that rated high on this list, but they are all restrictive in one way or another.

2) Whole food, very low carb diets like Atkins and keto are good for rapid weight loss, but they rank near the bottom of the list for every healthy diet category.

    • If you choose to lose weight on the Atkins or keto diets, switch to a healthier diet once you reach your desired weight loss.

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.

  • “Why is that?”, you might ask? The answer is simple. And it’s not that all 30 experts were prejudiced against low carb diets. It’s that the major primarily plant-based diets like Mediterranean, DASH, and flexitarian are backed by long-term clinical studies showing they are healthy and significantly reduce the risk of diabetes, heart disease, and other chronic diseases.
  • On the other hand, there are no long-term studies showing the Atkins and keto diets are healthy long term. And since the Atkins diet has been around for more than 50 years, the lack of clinical evidence that it is healthy long term is damming.

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. They are also at or near the top of almost every diet category.

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) 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.

What About Commercial Diets?

I chose not to review commercial diets by name, but let me make a few observations.

  • If you look at the gaps in my lists, it should be apparent that several commercial diets rank near the top for fast weight loss, but near the bottom on most healthy diet lists.
  • I do not recommend commercial diets that rely on ready-to-eat, low-calorie, highly processed versions “of your favorite foods”.
    • These pre-packaged meals are expensive. Unless you are a millionaire, you won’t be able to afford these meals for the rest of your life.
    • These pre-packaged meals are not teaching you healthy eating habits that will allow you to keep the weight off.
  • If you wish to spend your hard-earned dollars on a commercial diet, choose a diet that:
    • Relies on whole foods from all 5 food groups.
    • Teaches and provides support for the type of lifestyle change that leads to permanent weight loss.
  • Meal replacement shakes can play a role in healthy weight loss if:
    • They are high quality and use natural ingredients as much as possible.
    • They are part of a holistic lifestyle change program.

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 2023”.

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

#1: Which diets are best for rapid weight loss? Here are 2 general principles:

  1. If you are looking for rapid weight loss, any whole food restrictive diet will do.

2) If you choose to lose weight on the Atkins or keto diets, switch to a healthier diet once you reach your desired weight loss. Atkins and keto diets are good for rapid weight loss, but they rank near the bottom of the list for every healthy diet category.

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

  1. Choose a diet that fits your needs.

2) Choose diets that are healthy and associated with long term weight loss.

3) Choose diets that are easy to follow.

4) Choose diets that fit your lifestyle and dietary preferences.

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

Which Supplements Are Good For Your Heart?

How Should You Interpret This Study? 

Author: Dr. Stephen Chaney 

strong heartFebruary is Heart Health month. So, it is fitting that we ask, “What is the status of heart health in this country?” The American Heart Association just published an update of heart health statistics through 2019 (CW Tsao et al, Circulation, 145: e153-e639, 2022). And the statistics aren’t encouraging. [Note: The American Heart Association only reported statistics through 2019 because the COVID-19 pandemic significantly skewed the statistics in 2020 and 2021].

The Good News is that between 2009 and 2019:

  • All heart disease deaths have decreased by 25%.
  • Heart attack deaths have decreased by 6.6%.
  • Stroke deaths have decreased by 6%.

The Bad News is that:

  • Heart disease is still the leading cause of death in this country.
  • Someone dies from a heart attack every 40 seconds.
  • Someone dies from a stroke every 3 minutes.

Diet, exercise, and weight control play a major role in reducing the risk of heart disease. Best of all, they have no side effects. They represent a risk-free approach that each of us can control.

But is there something else? Could supplements play a role? Are supplements hype or hope for a healthy heart?

All the Dr. Strangeloves in the nutrition space have their favorite heart health supplements. They claim their supplements will single-handedly abolish heart disease (and help you leap tall buildings in a single bound).

On the other hand, many doctors will tell you these supplements are a waste of money. They don’t work. They just drain your wallet.

It’s so confusing. Who should you believe? Fortunately, a recent study (P An et al, Journal of the American College of Cardiology, 80: 2269-2285, 2022) has separated the hype from the hope and tells us which “heart-healthy” supplements work, and which don’t.

How Was This Study Done?

Clinical StudyThis was a major clinical study carried out by researchers from the China Agricultural University and Brown University in the US. It was a meta-analysis, which means it combined the data from many published clinical trials.

The investigators searched three major databases of clinical trials to identify:

  • 884 randomized, placebo-controlled clinical studies…
  • Of 27 types of micronutrients…
  • With a total of 883,627 patients…
  • Looking at the effectiveness of micronutrient supplementation lasting an average of 3 years on either…
    • Cardiovascular risk factors like blood pressure, total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides…or…
    • Cardiovascular outcomes such as coronary heart disease (CHD), heart attacks, strokes, and deaths due to cardiovascular disease (CVD) and all causes.

[Note: Coronary heart disease (CHD) refers to build up of plaque in the coronary arteries (the arteries leading to the heart). It is often referred to as heart disease and can lead to heart attacks (myocardial infarction). Cardiovascular disease (CVD) is a more inclusive term that includes coronary heart disease, stroke, congenital heart defects, and peripheral artery disease.]

The investigators also included an analysis of the quality of the data in each of the clinical studies and rated the evidence of each of their findings as high quality, moderate quality, or low quality.

Which Supplements Are Good For Your Heart?

The top 3 heart-healthy supplements in this study were:

Omega-3s And Heart DiseaseOmega-3 Fatty Acids:

  • Increased HDL cholesterol and decreased triglycerides, both favorable risk factors for heart health.
  • Deceased risk of heart attacks by 15%, all CHD events by 14%, and CVD deaths by 7% (see definitions of CHD and CVD above).
  • The median dose of omega-3 fatty acids in these studies was 1.8 g/day.
  • The evidence was moderate quality for all these findings.

Folic Acid:

  • Decreased LDL cholesterol (moderate quality evidence) and decreased blood pressure and total cholesterol (low quality evidence).
  • Decreased stroke risk by 16% (moderate quality evidence).

Coenzyme Q10:

  • Decreased triglycerides (high quality evidence) and reduced blood pressure (low quality evidence).
  • Decreased the risk of all-cause mortality by 32% (moderate quality evidence).
  • These studies were performed with patients diagnosed with heart failure. Coenzyme Q10 is often recommended for these patients, so the studies were likely performed to test the efficacy of this treatment.

There were three micronutrients (vitamin C, vitamin E, and vitamin D) that did not appear to affect heart disease outcomes.

Finally, as reported in previous studies, β-carotene increased the risk of stroke, CVD mortality, and all-cause mortality.

In terms of the question I asked at the beginning of this article, this study concluded that:

  • Omega-3, folic acid, and coenzyme Q10 supplements represent hope for a healthy heart.
  • Vitamin C, vitamin E, and vitamin D supplements represent hype for a healthy heart.
  • β-carotene supplements represent danger for a healthy heart.

But these conclusions just scratch the surface. To put them into perspective we need to dig a bit deeper.

How Should You Interpret This Study?

Question MarkIn evaluating the significance of these findings there are two things to keep in mind.

#1: This study is a meta-analysis and meta-analyses have both strengths and weaknesses.

The strength of meta-analyses is that by combining multiple clinical studies they can end up with a database containing 100s of thousands of subjects. This allows them to do two things:

  • It allows the meta-analysis to detect statistically significant effects that might be too small to detect in an individual study.
  • It allows the meta-analysis to detect the average effect of all the clinical studies it includes.

The weakness of meta-analyses is that the design of individual studies included in the analysis varies greatly. The individual studies vary in things like dose, duration, type of subjects included in the study, and much more.

This is why this study rated most of their conclusions as backed by moderate- or low-quality evidence. [Note: The fact that the authors evaluated the quality of evidence is a strength of this study. Most meta-analyses just report their conclusions without telling you how strong the evidence behind those conclusions is.]

#2: Most clinical studies of supplements (including those included in this meta-analysis) have two significant weaknesses.

  • Most studies do not measure the nutritional status of their subjects prior to adding the supplement. If their nutritional status for a particular nutrient was already optimal, there is no reason to expect more of that nutrient to provide any benefit.
  • Most studies measure the effect of a supplement on a cross-section of the population without asking who would be most likely to benefit.

You would almost never design a clinical study that way if you were evaluating the effectiveness of a potential drug. So, why would you design clinical studies of supplements that way?

With these considerations in mind, let me provide some perspective on the conclusions of this study.

Coenzyme Q10:

This meta-analysis found that coenzyme Q10 significantly reduced all-cause mortality in patients with heart failure. This is consistent with multiple clinical studies and a recent Cochrane Collaboration review.

Does coenzyme Q10 have any heart health benefits for people without congestive heart failure? There is no direct evidence that it does, but let me offer an analogy with statin drugs.

Statin drugs are very effective at reducing heart attacks in high-risk patients. But they have no detectable effect on heart attacks in low-risk patients. However, this has not stopped the medical profession from recommending statins for millions of low-risk patients. The rationale is that if they are so clearly beneficial in high-risk patients, they are “probably” beneficial in low-risk patients.

I would argue a similar rationale should apply to supplements like coenzyme Q10.

Omega-3s:

This study found that omega-3 reduced both heart attacks and the risk of dying from heart disease. Most previous meta-analyses of omega-3s and heart disease have come to the same conclusion. However, some meta-analyses have failed to find any heart health benefits of omega-3s. Unfortunately, this has allowed both proponents and opponents of omega-3 use for heart health to quote studies supporting their viewpoint.

However, there is one meta-analysis that stands out from all the others. A group of 17 scientists from across the globe collaborated in developing a “best practices” experimental design protocol for assessing the effect of omega-3 supplementation on heart health. They conducted their clinical studies independently, and when their data (from 42,000 subjects) were pooled, the results showed that omega-3 supplementation decreased:

  • Premature death from all causes by 16%.
  • Premature death from heart disease by 19%.
  • Premature death from cancer by 15%.
  • Premature death from causes other than heart disease and cancer by 18%.

This study eliminates the limitations of previous meta-analyses. That makes it much stronger than the other meta-analyses. And these results are consistent with the current meta-analysis.

Omega-3s have long been recognized as essential nutrients. It is past time to set Daily Value (DV) recommendations for omega-3s. Based on the recommendations of other experts in the field, I think the DV should be set at 500-1,000 mg/day. I take more than that, but this would represent a good minimum recommendation for heart health.

folic acidFolic acid:

As with omega-3s, this meta-analysis reported a positive effect of folic acid on heart health. But many other studies have come up empty. Why is that?

It may be because, between food fortification and multivitamin use, many Americans already have sufficient blood levels of folic acid. For example, one study reported that 70% of the subjects in their study had optimal levels of folates in their blood. And that study also reported:

  • Subjects with adequate levels of folates in their blood received no additional benefit from folic acid supplementation.
  • However, for subjects with inadequate blood folate levels, folic acid supplementation decreased their risk of heart disease by ~15%.

We see this pattern over and over in supplement studies. Supplement opponents interpret these studies as showing that supplements are worthless. But a better interpretation is that supplements benefit those who need them.

The problem is that we don’t know our blood levels of essential nutrients. We don’t know which nutrients we need, and which we don’t. That’s why I like to think of supplements as “insurance” against the effects of an imperfect diet.

Vitamins E and D:

The situation with vitamins E and D is similar. This meta-analysis found no heart health benefit of either vitamin E or D. That is because the clinical studies included in the meta-analysis asked whether vitamin E or vitamin D improved heart health for everyone in the study.

Previous studies focusing on patients with low blood levels of these nutrients and/or at high risk of heart disease have shown some benefits of both vitamins at reducing heart disease risk.

So, for folic acid, vitamin E, and vitamin D (and possibly vitamin C) the take-home message should be:

  • Ignore all the Dr. Strangeloves telling you that these vitamins are “magic bullets” that will dramatically reduce your risk of heart disease.
  • Ignore the naysayers who tell you they are worthless.
  • Use supplementation wisely to make sure you have the recommended intake of these and other essential nutrients.

β-carotene:

This meta-analysis reported that β-carotene increased the risk of heart disease. This is not a new finding. Multiple previous studies have come to the same conclusion.

And we know why this is. There are many naturally occurring carotenoids, and they each have unique heart health benefits. A high dose β-carotene supplement interferes with the absorption of the other carotenoids. You are creating a deficiency of other heart-healthy carotenoids.

If you are not getting lots of colorful fruits and vegetables from your diet, my recommendation is to choose a supplement with all the naturally occurring carotenoids in balance – not a pure β-carotene supplement.

The Bottom Line 

The Dr. Strangeloves in the nutrition space all have their favorite heart health supplements. They claim their supplements will single-handedly abolish heart disease (and help you leap tall buildings in a single bound).

On the other hand, many doctors will tell you these supplements are a waste of money. They don’t work. They just drain your wallet.

It’s so confusing. Who should you believe? Fortunately, a recent study has separated the hype from the hope and tells us which “heart-healthy” supplements work, and which don’t.

This study was a meta-analysis of 884 clinical studies with 883,627 participants. It reported:

  • Omega-3 supplementation deceased risk of heart attacks by 15% and all cardiovascular deaths by 7%.
  • Folic acid supplementation decreased stroke risk by 16%.
  • Coenzyme Q10 supplementation decreased the risk of all-cause mortality in patients with heart failure by 32%.
  • Vitamin C, vitamin E, vitamin D did not appear to affect heart disease outcomes.
  • β-carotene increased the risk of stroke, CVD mortality, and all-cause mortality.

Can Lifestyle Overcome Bad Genes?

Lifestyle, Genetics, And Dementia Risk 

Author: Dr. Stephen Chaney 

Cognitive-DeclineAlzheimer’s disease and other forms of dementia are among the most feared diseases of aging. What use is it to have a healthy body, a loving family, and a successful career if you can’t remember any of it? You should be able to enjoy your Golden years, not see them slip through your fingers.

If you have a family history of dementia or have sent your DNA off for testing and learned you are genetically predisposed to dementia, you are probably worried.

Perhaps the scariest thing about Alzheimer’s is that the medical community has no answers. There are no drugs to prevent or cure Alzheimer’s and brain transplants are out of the question. Some medical professionals will tell you nothing can be done, but is that true?

Before I answer that question let me share a fictional story because it provides a clue. In 1997, when I was still a relatively young scientist, I saw a film called GAATACA. [If you are looking for an entertaining film to watch, it is still available on some streaming services.]

This film envisioned a future society in which parents had their sperm and eggs sequenced so that their children would be genetically perfect. In that society the term “love child” had been redefined as a child who had been conceived without prior DNA sequencing.

The hero of this film was, of course, a love child. He was born with a genetic predisposition for heart disease. He was considered inferior, a second-class citizen of this future world.

Without giving away the plot of the film (I don’t want to spoil the enjoyment for you if you are thinking of watching it), he overcame his genetic inferiority. With a strict regimen of diet and physical fitness he became stronger and healthier than many of his genetically perfect peers.

This is when I first began to realize that our genes do not have to determine our destiny. We have the power to overcome bad genetics. We also have the power to undermine good genetics.

With that in mind, let’s return to Alzheimer’s. Studies have suggested that a healthy lifestyle can help reduce your risk of developing Alzheimer’s and other forms of dementia. But what about genetics? Will a healthy lifestyle only reduce your risk of dementia if your genetic risk is low, or will it be equally effective when your genetic risk is high? Can lifestyle overcome genetics?

The current study (A Tin et al, Neurology, 99: e154-e163, 2022) was designed to answer these questions.

How Was This Study Done?

clinical studyThis study included 11,561 participants from the Atherosclerosis Risk In Communities (ARIC) study. The ARIC study recruited middle-aged adults (average age of 54) from both urban and rural areas of the United States and followed them for 26 years. The participants were 57% female and 53% white.

Simply put, the study was designed to look at the effect of a healthy lifestyle on the genetic risk of developing dementia.

A healthy lifestyle was defined based on something called “Life’s Simple 7” (LS7) score.

  • The LS7 score was developed by the American Heart Association to define the effect of lifestyle on the risk of developing heart disease. However, it works equally well for defining the effect of lifestyle on risk of developing dementia.
  • The LS7 score consists of 7 modifiable health factors.
    • The factors are diet, physical activity, BMI (a measure of obesity), smoking, total cholesterol, blood pressure, and fasting blood glucose.
  • The data for deriving the LS7 scores were derived from data gathered from each participant when they enrolled in the ARIC study.
    • Diet was assessed by a 66-item food frequency questionnaire.
    • Physical activity and smoking were assessed in separate questionnaires.
    • BMI, blood pressure, total cholesterol, and fasting blood glucose were measured during a visit to a designated clinic at the beginning of the study.
  • Each modifiable health factor was separated into 3 categories (ideal, intermediate, and poor) and the highest score was assigned to the ideal category. The LS7 score was the sum of the scores from all 7 modifiable health factors.

Genetic risk of developing dementia was defined based on something called “The Genetic Risk Score” (GRS).

  • We have known for years that individuals of European descent who have the APOE ɛ4 gene variant have a 2 to 5-fold increased lifetime risk of developing dementia.
  • In recent years scientists have discovered several additional gene variants that increase the risk of dementia.
  • These have been combined with APOE ɛ4 to create a Genetic Risk Score for dementia.
  • The Genetic Risk Score for each participant was determined by DNA sequencing at the beginning of the study, with the highest score indicating the greatest risk for developing dementia.

The onset and severity of dementia were determined based on 7 clinic visits during the study.

  • Questionnaires were administered at each visit to assess self-reported dementia symptoms.
  • Cognitive tests were administered at visits 2 and 4.
  • Detailed cognitive and functional assessments were conducted at visits 5, 6, and 7.
  • The data were reviewed by an expert committee of physicians and neuropsychologists to determine dementia status.

Lifestyle, Genetics, And Dementia Risk

DNA TestingAt the end of the 26-year study:

  • When participants with the highest Genetic Risk Scores were compared to those with the lowest Genetic Risk Scores:
    • European American participants were 2.7-fold more likely to develop dementia.
    • African American participants were 1.55-fold more likely to develop dementia.
  • When participants with the highest LS7 (healthy lifestyle) scores were compared to those with the lowest LS7 scores:
    • European American participants were 40% less likely to develop dementia.
    • African American participants were 17% less likely to develop dementia.
    • A healthy lifestyle decreased the risk of developing dementia to a comparable extent at all levels of genetic risk for dementia.

The authors concluded, “Higher LS7 scores [a measure of a healthy lifestyle] are largely associated with a lower risk of incident dementia across strata of genetic risk [at all levels of genetic risk], supporting the use of LS7 [a healthy lifestyle] for maintaining brain health and offsetting genetic risk. More studies with larger study populations are needed…”

I should briefly comment on why African Americans were less responsive to both genetic risk and a healthy lifestyle than European Americans. The reasons for these discrepancies are not known, but:

  • There are socioeconomic factors and health disparities that increase the risk of dementia that are not included in the LS7 score.
  • A recent study has identified genetic risk factors for dementia that are unique to African Americans that are not included in the genetic risk score used in this study.

Can Lifestyle Overcome Bad Genes?

Dr. James Watson, who was co-discoverer of the DNA double helix and was heavily involved in the sequencing of the human genome, asked that he not be told about his risk of developing Alzheimer’s when his own DNA was sequenced in the early 2000’s. His reasoning was, “Why know the risk if you can’t change it?”

If the study I discussed today is true, you can modify the risk. Your genes don’t have to be your destiny. But is it true?

There is good reason to believe it might be true. Multiple studies have shown that each of the health factors included in LS7 score reduce the risk of developing dementia. However, most of those studies have not looked at the interaction between a healthy lifestyle and genetic risk.

Fortunately, there is another recent study that looked at the interaction between a healthy lifestyle and genetic risk of developing dementia.

  • This study used a different database (The UK Biobank study which enrolled 500,000 participants) and different criteria for defining a healthy lifestyle (diet, physical activity, smoking, and alcohol use).

However, the conclusions of this study were very similar:

  • People at high genetic risk were almost twice as likely to develop dementia as those at low genetic risk.
  • A healthy lifestyle decreased the risk of developing dementia by about 40% for both people at high genetic risk and for people at low genetic risk.

But this study went one step further than the study I discussed in this article. The British study reported that:

  • People at low genetic risk and an unhealthy lifestyle (the typical American) were just as likely to develop dementia as people at high genetic risk and a healthy lifestyle.

In other words, bad genetics does not doom you to Alzheimer’s and dementia. A healthy lifestyle can cut your risk almost in half. Conversely, good genetics is not a “Get Out of Jail Free” card. You can squander the advantage of good genetics with an unhealthy lifestyle.

And, just like the hero of the movie I discuss at the beginning of this article, a healthy lifestyle may be able to overcome bad genes and make you just as healthy (with respect to the risk of developing dementia) as people with good genes and an unhealthy lifestyle – which includes most Americans.

The Bottom Line 

Alzheimer’s disease and other forms of dementia are among the most feared diseases of aging. What use is it to have a healthy body, a loving family, and a successful career if you can’t remember any of it?

If you have a family history of dementia or have sent your DNA off for testing and learned you are genetically predisposed to dementia, you are probably worried.

Perhaps the scariest thing about Alzheimer’s is that the medical community has no answers. There are no drugs to prevent or cure Alzheimer’s and brain transplants are out of the question. Some medical professionals will tell you nothing can be done, but is that true?

Studies have suggested that a healthy lifestyle can help reduce your risk of developing Alzheimer’s and other forms of dementia. But what about genetics? Will a healthy lifestyle only reduce your risk of dementia if your genetic risk is low, or will it be equally effective when your genetic risk is high? Can lifestyle overcome genetics?

A recent study was designed to answer these questions. It found:

  • When participants with the highest Genetic Risk Scores were compared to those with the lowest Genetic Risk Scores:
    • They were 1.5 to 2.7-fold more likely to develop dementia.
  • When participants with the highest LS7 (healthy lifestyle) scores were compared to those with the lowest LS7 scores:
    • They were 17% to 40% less likely to develop dementia.
  • A healthy lifestyle decreased the risk of developing dementia to a comparable extent at all levels of genetic risk for dementia.

The authors concluded, “Higher LS7 scores [a measure of a healthy lifestyle] are largely associated with a lower risk of incident dementia across strata of genetic risk [at all levels of genetic risk], supporting the use of LS7 [a healthy lifestyle] for maintaining brain health and offsetting genetic risk. More studies with larger study populations are needed…”

This, and other studies discussed in this issue of “Health Tips For The Professor” suggest that your genes don’t have to determine your destiny. You can overcome bad genes with a healthy lifestyle.

Is Fast Food Fat Food?

by

Fat Metabolism Simplified 

Author: Dr. Stephen Chaney 

If you are like most Americans, you have vowed to lose weight and/or gain health in 2023. But how do you do that? There are hundreds of diets to choose from. And each diet has its “story” – a mixture of pseudo-science and testimonials – designed to convince you to try it.

Forget the pseudo-science. Forget the testimonials. Instead, focus on the one thing these diets have in common. They are all whole food diets. They all eliminate sodas, fast foods, and highly processed convenience foods.

In fact, that may be the simplest thing you can do to lose weight and become healthier. Many experts say that any time you eliminate sodas, fast foods, and convenience foods you will lose weight. If that statement is true, it could explain the American obesity epidemic. Between 1977 and 2017, a span of just 40 years, fast food consumption:

  • Increased from 6% to 35% (a 6-fold increase) in the 40-65 age group, and…
  • 11% to 46% (a 4-fold increase) in the 12-39 age group.

But is it true? There are certainly reasons to think it might be:

  • Fast foods are high in fat, sugar, and calories and are low in fiber – all of which are associated with obesity.
  • Big Food Inc has researched the ideal combination of taste, mouth feel, and effect on blood sugar to create an addiction to fast food.

However, the studies linking fast food consumption to obesity have been flawed.

  • People who consume fast foods tend to exercise less and have a poorer diet, even when they are eating at home. Previous studies have not distinguished between fast food consumption and other things (diet, exercise, lifestyle) that are also linked to obesity.
  • Previous studies have often only assessed diet and other lifestyle factors at the beginning or end of the study. There is no way of knowing whether these values are typical for the entire timespan of the study.
  • Previous studies have only shown associations, not cause and effect.

The current study (AO Odegaard et al, American Journal of Clinical Nutrition, 116: 255-262, 2022) was designed to eliminate many of the flaws in previous studies.

Fat Metabolism Simplified

You have probably heard that belly fat increases your risk of diabetes, heart disease, stroke, Alzheimer’s, and some cancers. This study looked at the effect of fast foods on belly fat, muscle fat, and fatty liver (liver fat).

However, belly fat is both simple and complicated:

  • It is simple in that it is easy to see. We talk about it as an “apple shape” and we measure it in waste circumference.
  • It is complicated because, anatomically, there are several subtypes of belly fat, and these authors chose to examine the effect of fast foods on each subtype.
  • However, the effect of fast foods on each subtype of belly fat, and the metabolic effects of each subtype, are similar. So, in the interest of simplicity, I will combine the subtypes and simply refer to the effect of fast foods on belly fat.

With that in mind, here is all you need to know about biology and metabolism of fat.

In addition to fat accumulation in the abdomen (belly fat), this study also looked fat accumulation in muscle (which I will refer to as muscle fat) and liver (which I will refer to as liver fat).

All three types of fat contribute to metabolic syndrome (prediabetes) characterized by:

  • Insulin resistance, which leads to an elevation of both glucose and insulin.
  • High LDL (bad cholesterol) and low HDL (good cholesterol).
  • High triglycerides.
  • High blood pressure.
  • Inflammation

These metabolic effects increase the risk of diabetes, heart disease, stroke, Alzheimer’s, inflammatory diseases, and some cancers.

In addition, liver fat can lead to non-alcoholic liver disease, fibrosis of the liver, and cirrhosis of the liver.

How Was This Study Done?

clinical studyThis study recruited 5115 participants from the Coronary Risk Development in Young Adults (CARDIA) study. This study recruited young adults (average age of 25) in 1985-1986 and followed them for 25 years. The participants were 57% female and 53% white.

As stated above, this study looked at the effect of fast foods on belly fat, muscle fat, and fatty liver (liver fat).

This study had numerous strengths:

  1. Unlike many other studies, variables like diet, fast food intake, and lifestyle were measured at multiple times during the study.
    • All participants entered treatment centers for physical exams, bloodwork, and lifestyle questionnaires at entry into the study (year 0) and again at years 2, 5, 7, 10, 15, 20, and 25.
    • On years 0, 7, 10, 15, 20, and 25 the questionnaires included the question, “How many times in a week or month do you eat breakfast, lunch, or dinner out in a place such as McDonald’s, Burger King, Wendy’s, Arby’s, Pizza Hut, or Kentucky Fried Chicken?” This question was used to calculate the number of times per week that participants ate fast food meals.
    • On years 0, 7, and 10 the quality of the non-fast-food portion of their diet was assessed by asking the participants to complete a comprehensive questionnaire about their typical intake of foods over the past month.
      • Diet quality was calculated using something called an alternative Mediterranean diet score because this calculation excludes foods commonly consumed at fast food restaurants. Thus, this calculation specifically measures the quality of the non-fast-food portion of their diet.
    • Each of these variables was averaged over the entire timespan of the study and trends (either an increase or decrease over time) were noted.
    • The outcomes of the study (belly fat, muscle fat, and liver fat) were measured at the end of the study (year 25) using CT imaging techniques.

2) The authors identified other factors that may have caused fat accumulation and corrected for them. For example:

    • Participants with the highest fast food consumption had lower educational level, lower income, poorer non-fast-food diet quality, lower physical activity, lower alcohol intake, higher caloric intake, and were more likely to be male and black.
    • Consequently, the data comparing fast food intake with fat accumulation were corrected for age, sex, race, education, income, smoking, alcohol, diet quality, caloric intake, and physical activity.

Is Fast Food Fat Food?

Fast food intake was equally divided into quintiles ranging from “Never to once a month” to “≥ 3 times per week”. When participants with the highest fast food intake over the past 25 years were compared to those with the lowest:

  • Their belly fat was higher by 48%.
  • Their muscle fat was higher by 27%
  • Their liver fat was 5-fold higher.
  • Their waist circumference (another measure of belly fat) was 11% (4 inches) more.
  • Their BMI (a measure of obesity) was 15% higher.

The authors concluded, “The results of this analysis robustly demonstrate that middle-aged adults who ate fast food more frequently over the past 25 years have significantly higher odds of MAFLD [fatty liver disease] and IAAT [belly fat]…aligned with poorer current and future cardiometabolic health [heart disease and diabetes] and chronic disease risk.”

What Does This Study Mean For You?

Several previous studies have shown that fast food consumption leads to fat accumulation and/or obesity. However, this is perhaps the best designed study on the effect of fast foods on fat accumulation and obesity to date. This is because:

  • It measured fast food consumption, non-fast-food diet quality, exercise, and many other lifestyle factors at multiple times during the 25-year study. That way we can be assured we are looking at fast food consumption and other lifestyle choices over the entire 25-year timespan of the study, not just at the beginning or end of the study.
  • The authors corrected the data for other lifestyle factors known to influence fat accumulation and obesity. Statistical corrections are never perfect, but these authors did their best to make sure the study only measured the effects of fast food consumption on fat accumulation.

Of course, this kind of study shows associations. It does not prove cause and effect. However, since 25-year double blind, placebo-controlled studies are not possible, this is perhaps the best study we may ever have.

That brings me back to your New Year resolutions. If you are like most Americans, you have probably resolved to lose weight and get healthier in past years – only to end the year fatter and less healthy than you started it.

You have probably tried dozens of diets. They worked for a while, but they were difficult to follow long term, and eventually you abandoned them.

My suggestion this year is to forget the crazy diets. Just go for a simple change. Eliminate sodas, fast foods, and convenience foods from your diet. You will lose weight. And you will be healthier. Guaranteed.

Of course, it’s not that simple. Remember that Big Food Inc has designed these foods to be addictive. Unless you have an iron will, you probably won’t be able to go cold turkey.

You may need a gradual approach. Replace sodas, fast and convenience foods one at a time. Find healthier substitutes for each fast food you replace. Then explore more convenient ways to eat healthy. It will be a journey. But the end results will be worth it.

The Bottom Line 

If you are like most Americans, you have vowed to lose weight and/or gain health in 2023. But how do you do that? There are hundreds of diets to choose from. And each diet has its “story” – a mixture of pseudo-science and testimonials – designed to convince you to try it.

Forget the pseudo-science. Forget the testimonials. Instead, focus on the one thing these diets have in common. They are all whole food diets. They all eliminate sodas, fast foods, and highly processed convenience foods.

Many studies have implicated sodas, fast and convenience foods in obesity and fat accumulation in our bodies. But these studies have all had their flaws.

A recent study looked at the association between fast food intake and 3 kinds of fat (belly fat, muscle fat, liver fat) over 25 years. All 3 kinds of fat are highly associated with metabolic syndrome (prediabetes) and several chronic diseases. More importantly, this study was designed to eliminate many of the flaws in previous studies.

When participants with the highest fast food intake over the past 25 years were compared to those with the lowest:

  • Their belly fat was higher by 48%.
  • Their muscle fat was higher by 27%.
  • Their liver fat was 5-fold higher.
  • Their waist circumference (another measure of belly fat) was 11% (4 inches) more.
  • Their BMI (a measure of obesity) was 15% higher.

The authors concluded, “The results of this analysis robustly demonstrate that middle-aged adults who ate fast food more frequently over the past 25 years have significantly higher odds of MAFLD [fatty liver disease] and IAAT [belly fat]…aligned with poorer current and future cardiometabolic health [heart disease and diabetes] and chronic disease risk.”

Simply put, the best thing you can do for your weight and your health this year is to eliminate sodas, fast foods, and convenience foods from your diet. You will lose weight. And you will be healthier. Guaranteed.

Relief From Knee Pain

What Causes Knee Pain? 

Author: Julie Donnelly, LMT –The Pain Relief Expert

Editor: Dr. Steve Chaney 

Closing Out the Old Year And Starting A New One

Walking FastI hope that 2022 was kind to you and your family.  Covid seemed to come and go, with new strains popping up every time we turned around.  What a year!

In December the foods all seemed to be fattening – delicious for sure, but fattening.  Which brings me to the topic of the month.  Maybe you are trying to walk off some of the extra calories you put on last month.

Walking will help burn the calories, but it can also come with aches and pains from muscles getting used repetitively.

This month I want to focus on the pain you feel on the outside of your knee after several days of walking more than your body is used to. It can reduce your walks to a slow hobble at best. And that isn’t going to burn off any extra calories.

What Causes Knee Pain?

The muscle I want to talk about this month is Tensor Fascia Lata (called TFL for short).

If you make a fist with both hands and then put them on your hips, you are right on top of the TFL.  A small muscle, the TFL attaches to a very long tendon called the iliotibial band (ITB).

This tendon is blamed for pain on the outside of your knee, and while it does insert there so it causes pain when it is tight, it’s only tight because of the TFL.

Sounds like you’re going in circles but let me explain.

The TFL is responsible for stabilizing your knee when you are standing on one foot.  You don’t think about it, but you are on one foot with every step to take!

You can feel the muscle contract by pressing your fingertips into the muscle on each hip, and then move from one leg to the other. You’ll feel the muscle tighten.

The repetitive movement causes the muscle to shorten, and it pulls up on the ITB.  This will cause tension to be put on the insertion point at your knee and causes pain. It will also limit range-of-motion when you are walking.

It’s interesting that most people don’t feel the pain in their hip, but they definitely feel it on the outside of their knee.

Relief From Knee Pain 

If you are experiencing pain on the outside of your knee while walking, your Tensor Fascia Lata muscle is probably too tight. Here is how to treat your TFL muscle.

Place the ball as shown in this picture.

Move around a little bit until you find the tight spot.  It will be painful.

Only add enough pressure that it “hurts so good,” and then stay there for 30 seconds.  Release the pressure. Repeat 2-3 times until it doesn’t hurt.

Zoom Consultations 

Almost every month I have been showing you how to do a self-treatment that I’ve developed.  And, as you know, I’ve written books that have all the self-treatments, including many that I don’t put into this newsletter.

However, your specific situation my require more than just the basics that I show here in the newsletter.

You can still get help!

I’ve been doing Zoom consultations for several years, and they really work well.

In fact, you get instruction that is specific to your needs, and often I’ll demonstrate the movement, and I always make sure you are doing it correctly.

Work directly with me by going to https://julstromethod.com/product/private-consultation/.

A picture is worth 1000 words – and a Zoom consultation is priceless!

Next Month: Bunion Relief 

We’ll be looking at how muscles can pull on the bones that protrude at the base of your big toe and become a bunion.

Wishing you and your family a Healthy and Happy New Year!

Which Diet Is Best For Diabetics?

by

What Did This Study Show? 

Author: Dr. Stephen Chaney 

High Blood SugarWhen you were first diagnosed with diabetes, your doctor probably told you that your life will forever be changed. Among other things he or she probably told you that you would need to make some radical changes to your diet.

But what changes? Both the American Diabetes Association (ADA) and Diabetes UK (the British version of ADA) recommend:

  • An individualized approach. This recognizes that we are all different. What works for some diabetics may not work for others.
  • A diet that incorporates more non-starchy vegetables and minimizes added sugars and refined grains.

But these recommendations are vague. Most people want a specific diet to follow. It’s here that Diabetes UK and the ADA part ways.

  • Diabetes UK gives its highest recommendation to the Mediterranean diet.
  • The ADA gives equal recommendations to the Mediterranean diet and both low-carbohydrate and very-low carbohydrate diets.

But which diet is best? It’s hard to know because most studies compare one of these diets to the standard American diet (SAD), and anything is better than the standard American diet.

Fortunately, one recent study (CD Gardner et al, American Journal of Clinical Nutrition, 116: 640-652, 2022) directly compares the two extremes of ADA-recommended diets, the Mediterranean diet and the Keto diet.

How Was This Study Done?

clinical studyThis study recruited 33 participants with diabetes or prediabetes from the San Francisco Bay area. The participants in the study:

  • Were between 41 and 77 years old (average age = 60.5).
  • Were 61% male, 45% non-Hispanic white, and mostly (85%) college educated.
  • Had either prediabetes (61%) or diabetes (39%).
  • Had BMIs ranging from 22.7 (normal) to 39.7 (obese) (average BMI = 30 (borderline obese).
  • Had elevated levels of HbA1c (hemoglobin A1c, a measure of long-term blood sugar control).

People were excluded from the study if they were:

  • Underweight (<110 pounds) or morbidly obese (BMI ≥40).
  • Had extremely high cholesterol (LDL cholesterol >190 mg/dL) or blood pressure (>169 mmHg).
  • On insulin or certain medications to lower blood sugar levels.

This was a randomized, crossover, interventional study. Simply put, that means:

  • The study started with participants eating a typical American diet. The intervention was either a Keto diet or a Mediterranean diet.
  • Each patient was randomly assigned to one of the diets for 12 weeks. Then they “crossed over” to the other diet for 12 weeks. In this type of study each patient serves as their own control.
  • Finally, there was a 12-week follow-up period in which they could choose which of the two diets to follow.

It was a very well-controlled study:

  • Participants were given detailed guidelines to follow and received weekly individual education sessions by a registered dietitian and certified diabetes educator.
  • During the first 4 weeks of each diet, participants were provided at no cost all meals and snacks from a local food delivery service.
  • During the next 8 weeks of each diet, the participants purchased their own foods using the same guidelines they had been given during the first 4 weeks.
    • They were also provided with a recipe booklet and suggestions for diet-compliant menu items at local restaurants for each diet.
  • This was not designed as a weight loss diet. The participants were provided with 2,800 calories of food per day and instructed to eat until they were full.
  • Compliance with the diet was assessed in three ways:
    • During week 4 and week 12 of each diet phase, 3 unannounced 24-hour dietary recalls (2 on weekdays and 1 on a weekend day) were administered over the phone by a trained nutritionist.
    • Participants were also given an app to log in their food intake daily.
    • Participants on the Keto diet were given blood ketone monitors and strips.
  • Finally, at the beginning and end of the study and during weeks 4 and 12 of each diet phase participants went to a medical facility for blood work and weight measurements.

The primary focus of this study was measuring the effect of each diet on HbA1c. HbA1c measures blood sugar control over the previous 12 weeks (which is why each diet phase was 12 weeks long). But the study also measured the effect of each diet on LDL cholesterol, HDL cholesterol, and triglycerides.

What Were The Diets Like?

Vegetarian DietThese were not ordinary versions of the Mediterranean and Keto diets:

  • Sugar and refined flour are often part of the diet in Mediterranean regions. So, this study used the “Mediterranean Plus (Med-Plus)” diet which restricts both sugar and refined grains.
  • Keto convenience foods are often a witch’s brew of artificial ingredients. So, this study used the “Well-Formulated Keto Diet (WFKD)” which is composed of whole, unprocessed foods. In fact, both diets were whole food diets.

In summary, the two diets were:

  • Alike in that both emphasized non-starchy vegetables and minimized sugar and refined grains.
  • Alike in that they were both whole food diets.
  • Different in that the Keto diet eliminated legumes, fruits, and whole grains while the Mediterranean diet included them.

The macronutrient composition of the two diets was about what you would expect.

  • The baseline diet was typical of the American diet. It was higher than recommended for fat. While carbohydrate intake appeared to be moderate, it was high in sugar and refined grains.
  • The Keto and Mediterranean diet interventions were separated into 2 phases. In phase 1 (weeks 1-4) every meal and snack were provided to the participants. In phase 2 (weeks 5-12) they purchased their own food.
  • As expected, carbohydrate intake was much lower, fat intake much higher, and protein intake slightly higher than baseline for the Keto diet. And this pattern was maintained during the 8 weeks the participants purchased their own food.

  • The Keto diet was significantly lower in percent polyunsaturated fat and slightly higher in percent monounsaturated and saturated fat than baseline (the typical American diet) in weeks 1-4. However, remember that the Keto diet was 50% higher in total fat than the other diets. This makes it significantly higher in saturated fat than either the baseline or Mediterranean diets.
  • As expected, the Mediterranean diet was significantly higher in percent monounsaturated fat and lower in percent saturated fat than baseline in weeks 1-4.
  • Not surprisingly, both diets trended towards the baseline diet in the 8 weeks participants were buying their own food.

Other interesting differences between the two diets:

  • The Keto diet contained around 12% plant protein and 88% animal protein, while the Mediterranean diet contained about 50% of each.
  • Fiber intake decreased by 33% compared to baseline on the Keto diet, while fiber intake increased by 50% on the Mediterranean diet.
  • In terms of nutritional adequacy, the Keto diet was significantly lower in fiber, vitamin C, folate, and magnesium than the Mediterranean diet.

What Did The Study Show?

Question Mark1. Participants consumed around 300 fewer calories/day and lost about 15 pounds on both diets.

    • The authors speculated this was because both diets were more filling than the baseline diet, presumably because both diets were whole food diets while the baseline diet contained lots of processed foods high in sugar and refined grains.

2) Both diets reduced HbA1c (a cumulative measure of how much the diets improved blood sugar control compared to the baseline diet) by about the same extent.

3) LDL cholesterol (bad cholesterol) increased by about 10% on the Keto diet, while it decreased by about 9% on the Mediterranean diet. This difference was highly significant.

4) HDL cholesterol increased by about the same extent on both diets.

5) Triglycerides decreased by around 20% on the Keto diet and by 10% on the Mediterranean diet. This difference was also highly significant.

6) Finally, adherence to the Keto diet was less than for the Mediterranean diet. Plus, more people chose the Mediterranean diet during the follow-up phase when they were allowed to choose their own diet.

The authors concluded, “HbA1c values…improved from baseline on both diets, likely due to several shared dietary aspects. The WFKT [Keto diet] led to a greater decrease in triglycerides, but also had untoward risks from elevated LDL cholesterol and lower nutrient intakes from avoiding legumes, fruits, and whole, intact grains, as well as being less sustainable [easy to follow long-term].

Once again, I have covered lots of information in this blog. But if you are diabetic, you are probably wondering, “What does this mean for me?” Let me start by reviewing the purpose of this study.

  • This study was designed to compare the two extremes of recommended diets (Mediterranean and Keto) with respect to their effectiveness at keeping blood sugar under control.
  • These were both more restrictive versions of the two diets than most people follow. In this study, both diets:
    • Were whole food diets. No sodas, processed, or convenience foods were allowed.
    • Minimized the consumption of sugars and refined grains.

Now let me divide the discussion into two sections:

  1. Which diet is best for diabetics in the short term (in this case, 12 weeks)?
    • Participants consumed 300 fewer calories and lost about 15 pounds on both diets in spite of being given more than they could eat and not being encouraged to lose weight.
      • The authors attributed this to whole food diets being more filling.
      • However, it is also consistent with my contention that any restrictive diet will lead to short-term weight loss and improvement in blood sugar control. I summarize the 5 reasons for this phenomenon in last week’s “Health Tips From the Professor” article
    • Blood sugar control over 12 weeks, as measured by HbA1c, improved by the same amount on both diets.
      • That is consistent with the American Diabetes Association’s position that a variety of diets, ranging from Mediterranean to Keto, are suitable for diabetics.
      • This also means that you can forget the advice that diabetics need to follow a low carb diet and give up fruits, whole grains, and legumes to keep their blood sugar under control.
      • However, this is not a “get out of jail free card”. Diabetics do need to avoid sodas, processed, and convenience foods and minimize sugar and refined grains.
    • There was considerable individual variability. Some people did better on the Mediterranean diet. Others did better on the Keto diet.
    • This is consistent with the American Diabetes Association’s recommendation that diabetic diets should be individualized.

In short, this study suggests that in the short term (12 weeks) the Med-Plus and WFKD Keto diets are equally effective at promoting weight loss and improved blood sugar control for both diabetics and prediabetics.

However, there is considerable individual variability, meaning that diabetics can chose the diet that works best for them.

2) Which diet is best for diabetics in the long term?

If both diets are equally effective short term, the important question becomes whether they are equally successful and equally healthy long term.

As noted in the author’s conclusion, this study raised several “red flags” which suggest the Keto diet might be less successful and less healthy long term. But this is a short-term study.

You may be wondering, “What do long-term studies show?” Unfortunately, there are very few long-term studies to guide us. But here is what we do know.

    • There are multiple studies showing that the Mediterranean diet reduces the risk of diabetes, heart disease, and some cancers long term. There is no evidence that meat-based low carb diets are healthy long term. This includes the Atkins diet, which has been around more than 50 years.
    • A 6-year study reported that the group with the lowest carbohydrate intake had an increased risk of premature death – 32% for overall mortality, 50% for cardiovascular mortality, 51% for cerebrovascular mortality, and 36% for cancer mortality.
    • A 20-year study reported that women consuming a meat-based low carb diet for 20 years gained just as much weight and had just as high risk of diabetes and heart disease as women consuming a high carbohydrate, low fat diet.

In short, the few long-term studies we do have suggest that the Mediterranean diet is a better choice for long-term health and reduced risk of diabetes than low-carb diets.

The Bottom Line 

If you are diabetic or prediabetic, the American Diabetes association recommends a diet that is individualized and ranges from Mediterranean to low carb and very low carb (Keto).

However, low carb and Keto enthusiasts insist that diabetics need to follow a low carb or very low carb diet. And that seems to make sense. After all, aren’t carbs the problem for diabetics?

To resolve this question, a recent study was designed to compare the two extremes of the ADA-recommended diets (Mediterranean and Keto) with respect to their effectiveness at keeping blood sugar under control.

These were not ordinary versions of the Mediterranean and Keto diets:

  • Sugar and refined flour are often part of the diet in Mediterranean regions. So, this study used the “Mediterranean Plus (Med-Plus)” diet which restricts both sugar and refined grains.
  • Keto convenience foods are often a witch’s brew of artificial ingredients. So, this study used the “Well-Formulated Keto Diet (WFKD)” which is composed of whole, unprocessed foods. In fact, both diets were whole food diets.

In short, this study found that in the short term (12 weeks) the Med-Plus and WFKD Keto diets are equally effective at promoting weight loss and improved blood sugar control for both diabetics and prediabetics.

The authors concluded, “HbA1c values…improved from baseline on both diets, likely due to several shared dietary aspects. The WFKT [Keto diet] led to a greater decrease in triglycerides, but also had untoward risks from elevated LDL cholesterol and lower nutrient intakes from avoiding legumes, fruits, and whole, intact grains, as well as being less sustainable [easy to follow long-term].

If both diets are equally effective short term, the important question becomes whether they are equally successful and equally healthy long term.

As noted in the author’s conclusion, this study raised several “red flags” suggesting that the WFKD Keto diet may be less successful and less healthy long term than the Med-Plus diet. However, this was a short-term study.

So, the question becomes, “What do long-term studies show?” There are few long-term studies of low-carb diets, but the few long-term studies we do have suggest that the Mediterranean diet is a better choice for both long-term health and reduced risk of diabetes than most low-carb diets.

Which Diet Is Best?

Author: Dr. Stephen Chaney

It’s the beginning of January. Weight loss season has just launched again. Like millions of Americans, you have probably set 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 mistakes to avoid and…
  • 6 tips on what to look for…
  • 7 tips for making weight loss permanent…

…when you are choosing the best diet for you.

Mistakes To Avoid When Choosing The Best Diet

Avoid1. Endorsements

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 for 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.

Magic4) “Magic” Diets.

I 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.

Tips For Successful Weight Loss

SkepticWhat should you look for in choosing a healthy weight loss diet? Here are my top 6 tips.

1. 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.

When we 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 Keeping The Weight 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 at least 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, whole food 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 lower-carb version of the Mediterranean diet called Med-Plus. It is a whole food version of the Mediterranean diet that minimizes added sugar and refined grains (I will be talking more about it in next week’s “Health Tips From the Professor”).
    • 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 this year, you are probably asking, “Which Diet Is Best?” In this issue of “Health Tips From The Professor” I give you:

  • 4 tips on mistakes 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.

How Much Should You Walk? 

Author: Dr. Stephen Chaney 

Overweight People ExercisingThe new year is almost here. If you are like millions of Americans, you may already be making plans to join a gym, get a personal trainer, or join a spin class.

The problem is these are all expensive options. And a good portion of that money is wasted. To put it into perspective, let’s look at some statistics

  • Around 6 million Americans buy gym memberships every January.
  • 67% of those memberships are never used.
  • For those memberships used in January, another 50% are not in use 6 months later.
  • Americans spend about 1.6 billion dollars on unused gym memberships every year.
  • And that doesn’t include those gym memberships that are only occasionally used.

If you want to get fit and healthy in the new year, perhaps you should consider a less expensive option – like walking. Your only investments are a good pair of walking shoes and a device that keeps track of the number of steps you take (eg, Fitbit, smart watch, or smart phone).

You still may give up on your New Year’s goal of getting fitter at some point. But you won’t have wasted so much money.

Of course, you probably have some questions about the benefits of walking, such as:

  1. Is walking enough to significantly improve my fitness and health?

2) How far (how many steps) should I walk?

3) How fast should I walk?

Fortunately, two recent studies (B del Pozo-Cruz et al, JAMA Internal Medicine, 182: 1139-1148, 2022; J del Pozo-Cruz et al, Diabetes Care, 45: 2156-2158, 2022) have answered all three questions.

How Were These Studies Done?

clinical studyThe first study (B del Pozo-Cruz et al, JAMA Internal Medicine, 182: 1139-1148, 2022) followed 78,500 participants (average age 61, 55% female, 97% white) enrolled in the UK Biobank study for an average of 7 years.

At the time of enrollment, each participant was given an accelerometer (a device that measures the number and frequency of steps) to wear on their dominant wrist for 24 hours/day for 7 days. The investigators used the accelerometer data to categorize several types of physical activity.

  • Daily step counts (the average number of steps per day for 7 days). These step counts were further subdivided into two categories:
  • Incidental steps (It was assumed that ˂40 steps/min represented steps taken that were incidental to normal daily activities).
  • Purposeful steps (It was assumed that ≥40 steps/min represented steps taken as part of planned exercise).
  • Stepping intensity (the highest frequency of steps/min averaged over 30 min intervals for all 7 days).

At the end of the study, each of these variables was correlated with the risk of premature deaths due to all causes, cancer, and heart disease.

The second study (J del Pozo-Cruz et al, Diabetes Care, 45: 2156-2158, 2022) was similar except that it:

  • Used data from 1687 adults (average age = 55, 56% male, with diabetes or prediabetes when the study began) in the 2005-2006 National Health and Nutrition Examination Survey in the US.
  • Followed participants for 9 years instead of 7.
  • Only measured total steps/day
  • Correlated total steps/day with premature death for participants who already had prediabetes or diabetes when they entered the study.

Walking Your Way To Health

Study 1 looked at the effect of walking on health outcomes in multiple ways.

woman walking dog#1: Increase in number of steps/day:

  • On average study participants took an average of 7200 steps per day, but this ranged from a low of 3,200 steps/day to a high of 12,200 steps/day.
  • Each increase of 2,000 steps/day was associated with a:
    • 8% decrease in all-cause mortality.
    • 11% decrease in cancer mortality.
    • 10% decrease in heart disease mortality.
  • Overall, increasing from 3,200 steps/day to 10,000 steps/day decreased all-cause, cancer, and heart disease mortality by around 36%.
  • There was no minimum threshold to this beneficial effect of walking on the risk of premature death.
  • The benefits of walking appeared to plateau at 10,000 steps/day.

#2: Increase in number of incidental steps/day (steps taken that are incidental to normal daily activities):

  • On average study participants took 3240 incidental steps/day, but this ranged from a low of 2,100 steps/day to a high of 4,400 steps/day.
  • Each 10% increase in incremental steps/day was associated with a:
    • 6% decrease in all-cause mortality.
    • 6% decrease in cancer mortality.
    • 10% decrease in heart disease mortality.

#3: Increase in number of purposeful steps/day (steps taken as part of planned exercise):

  • On average study participants took 4,600 purposeful steps/day, but this ranged from a low of 1,600 steps/day to a high of 8,600 steps/day.
  • Each 10% increase in purposeful steps/day was associated with a:
    • 7% decrease in all-cause mortality.
    • 8% decrease in cancer mortality.
    • 10% decrease in heart disease mortality.

#4: Increase in speed of walking or cadence. The measurement they used was “peak-30 cadence” – the Walking Fasthighest average steps/min during a 30-minute interval within a day:

  • On average study participants had a “peak-30 cadence” of 76 steps/min, but this ranged from a low of 47 steps/min to a high of 109 steps/min.
  • Each 10% increase in “peak-30 cadence” was associated with a:
    • 8% decrease in all-cause mortality.
    • 9% decrease in cancer mortality.
    • 14% decrease in heart disease mortality.
  • The benefits of walking rapidly (increase in “peak-30 cadence”) were in addition to the benefits seen by increasing the number of steps per day.
  • Overall, increasing from a “peak-30 cadence” of 47 steps/min to 109 steps/min decreased all-cause, cancer, and heart disease mortality by an additional 34%.
  • There was no minimum threshold to this beneficial effect of increasing “peak-30 cadence” (the speed of walking) on the risk of premature death.
  • The benefits of increasing “peak-30 cadence” appeared to plateau at 100 steps/min.

#5 Effect of walking on the prevention of heart disease and cancer: The investigators measured this by strong heartlooking at the effect of walking on the “incidence” of heart disease and cancer (defined as new diagnoses of heart disease and cancer) during the study. They found.

  • Each 2,000-step increase in the total number of steps/day decreased the risk of developing heart disease and cancer by 4% during this 7-year study.
  • Each 10% increase in the number of purposeful steps/day decreased the risk of developing heart disease and cancer by 4% during this study.
  • Each 10% increase in “peak-30 cadence” decreased the risk of developing heart disease and cancer by 7% during this study.

The authors concluded, “The findings of this population-based…study of 78,500 individuals suggest that up to 10,000 steps/day may be associated with a lower risk of mortality and cancer and CVD incidence. Steps performed at a higher cadence may be associated with additional risk reduction, particularly for incident disease.”

Study 2 extended these findings to diabetes. They started with participants that had either prediabetes or diabetesdiabetes and followed them for 9 years. They found that:

  • Study participants with prediabetes ranged from a low of 3,800 steps/day to a high of 10,700 steps/day.
    • Prediabetic participants walking 10,700 steps/day were 25% less likely to die during the study than participants walking only 3,800 steps/day.
  • Study participants with diabetes ranged from a low of 2,500 steps/day to a high of 10,200 steps/day.
    • Diabetic participants walking 10,200 steps/day were also 25% less likely to die during the study than participants walking only 2,500 steps/day.
  • Even small increases in the number of steps per day decreased the risk of premature death for both prediabetic and diabetic participants.
  • Once again, 10,000 steps/day appeared to be the optimal dose to lower the risk of premature death for both diabetic and prediabetic patients.

The authors of this study concluded, “Accumulating more steps/day up to ~10,000 steps/day may lower the risk of all-cause mortality of adults with prediabetes and diabetes.”

How Much Should You Walk?

Walking CoupleThat was a lot of information. You are probably wondering what it means for you. Let’s start with the big picture:

  • Going from couch potato to 10,000 steps per day may reduce your risk of premature death due to all causes, cancer, and heart disease by 36% (24% if you are already prediabetic or diabetic).
  • Increasing the speed with which you walk from 47 steps/min to 109 steps/min sustained for 30 minutes may reduce your risk of premature death by an additional 34%.

In other words, simply walking more and walking faster can have a significant on your health. I am not recommending walking as your only form of exercise. I’m just saying not to consider it inferior to other forms of exercise.

  • There is no lower limit to the benefits of walking. Even small increases in the number of steps/day you take and the speed with which you walk may have a beneficial effect on your health.

In other words, you don’t need to speed walk 10,000 steps/day to reap a benefit from walking. Even small increases are beneficial. That’s good news for those of you who may not be able to speed walk long distances. It also means that if you are a couch potato, you don’t need to attempt 10,000 steps at high speed from day 1. You can work up to it gradually.

  • Incidental walking (walking that is incidental to your daily activities) is almost as beneficial as purposeful walking (walking as part of a planned exercise).

That’s good news for those of you who may not have time for long walks. It also means that advice like “park your car at the far end of the parking lot and walk” or “take the stairs rather than the elevator” can have a meaningful impact on your health.

  • The benefits of walking appear to max out at around 10,000 steps per day and a cadence of 100 steps/min sustained for 30 minutes.

That means once you get to those levels, it’s time to consider adding other kinds of exercise to your regimen. More and faster walking may offer little additional benefit.

Finally, in the words of the authors, “This information could be used to motivate the least active individuals to increase their steps and the more-active individuals to reach the 10,000-step target.”

The Bottom Line 

The new year is almost here. If you are like millions of Americans, you may already be making plans to join a gym, get a personal trainer, or join a spin class.

If you want to get fit and healthy in the new year, perhaps you should also consider a less expensive option – like walking.

Of course, you probably have some questions about the benefits of walking, such as:

1) Is walking enough to significantly improve my fitness and health?

2) How far (how many steps) should I walk?

3) How fast should I walk?

Fortunately, two recent studies have answered all three questions. They found:

  • Going from couch potato to 10,000 steps per day may reduce your risk of premature death due to all causes, cancer, and heart disease by 36% (24% if you are already prediabetic or diabetic).
  • Increasing the speed with which you walk from 47 steps/min to 109 steps/min sustained for 30 minutes may reduce your risk of premature death by an additional 34%.
  • There is no lower limit to the benefits of walking. Even small increases in the number of steps/day you take and the speed with which you walk may have a beneficial effect on your health.
  • Incidental walking (walking that is incidental to your daily activities) is almost as beneficial as purposeful walking (walking as part of a planned exercise).
  • The benefits of walking appear to max out at around 10,000 steps per day and a cadence of 100 steps/min sustained for 30 minutes.

In the words of the authors of these studies, “This information could be used to motivate the least active individuals to increase their steps and the more-active individuals to reach the 10,000-step target.”

Merry Christmas

Christmas GiftI love the Christmas season. The colors, the smells, the sounds of music. I’m a vegan so turkey isn’t happening for me, but the array of deliciously prepared vegetables, and the variety of desserts always make me excited for this month to get underway!

We give so much to others, especially during this season, that I want to remind you to take care of yourself too.  Like they say on the airplane, ”Put on your own oxygen mask first!”  One of the best gifts you can give to those you love, is a healthy and happy you!

Eliminate the aches and pains that can make you feel grumpy, and if you have someone who could benefit from eliminating pain, please feel free to send them my way.  That includes people who don’t live near me. I will give you information on how to set up Zoom consultations below. I’ll be happy to help you.

I hope you have a wonderful, blessed Christmas!

What Causes Plantar Fasciitis Pain?

It has been a beautiful time for being outdoors the past couple of months, whether you live here in Florida, or any of the northern states. With the cooler, dryer weather, runners are back out on the road, which can lead to our topic of the month.  Plantar fasciitis is a condition that is felt in the arch of the foot and can hamper, or even stop, runners from enjoying their sport.

The good news is I’ve found that there are four muscles that are key to releasing the pain in your arch. And they are easy to self-treat with just a little direction.  These muscles are:

The calf muscles:

 

 

Gastrocenmius & Soleus. These muscles both merge into your Achilles tendon and pull up on your heel bone so you can stand on your toes.

 

 

 

The Tibialis Anterior Muscle:

 

 

This muscle is on the outside of your shin bone.  It inserts into the inside of your arch and rolls your foot out toward your little toe.

 

 

 

The Peroneal Muscles: 

Actually  TWO muscles that are on top of each other with both of them going along the outside of your shin bone,and  behind your ankle.  One inserts into the long bone on the outside of your foot, and the other goes across your arch, inserting into the long bone on the inside of your arch.

That may sound a little confusing, but if it does, take a look at the muscle by doing an internet search and it will be clear.

Together these insertion points pull the outside of your foot UP so your roll in toward your arch.

The important point to consider is that all four of these muscles insert into the bones that form your arch.

When your calf muscles are tight they are pulling back on your heel bone, but since your arch muscles originate on your heel bone, they are being stretched backward.

When the Tibialis Anterior muscle is pulling on the long bone on the inside of your arch, it’s causing pain on that bone so you feel pain in your arch.

When the Peroneals are pulling toward the outside of your foot, you again feel pain along that bone.

This all sounds confusing but just think about your  arch being pulled in three different directions: to the outside, to the inside, and back toward your heel.  Of course you’re going to have pain in your arch!

It would take the length of a long article to go into the details of how to treat each of these muscles so I’m only going to show pictures of how to treat the muscles on the front of, and next to your shin.

Use either the Perfect Ball that I sell on my website: www.flexibleathlete.com, or a used tennis ball.

Kneel on the floor as shown in the picture to the left and place the ball to the outside of your shin bone.

Move your leg forward so the ball rolls down toward your ankle.  If you start to feel a cramp in your arch, just curl your toes as shown in this picture.

You’ll find a tender spot about midway down the muscle.  This is the muscle spasm that is putting pressure on the inside of your arch.

Repeat until it no longer hurts.

To treat your Peroneals, sit as shown in the picture on the right. Place the ball as shown in the picture and put your hand so it presses your leg directly into the ball.

Move your leg so the ball rolls down the outside of your leg toward your ankle.

 

Be sure to always move your hand so it stays on top of the ball.

 

You’ll find a tender spot about midway down your leg.  Stay on the point for about 15 seconds and continue to roll down your leg.

 

Repeat until the muscle no longer hurts.

Next month I’ll be talking about Achille’s Tendonitis.  The treatment for the calf muscles is the same as you would use for Plantar Fasciitis, so stay tuned…

Zoom Consultations 

This past month I worked with two people via Zoom.  Both were successful at getting a total resolution to their issue.  I’ll tell you about them next month, but in one case it was a sudden attach of severe back pain at prevented the man from even getting out of bed.  In the other case, it was a young woman who is a sub-elite runner who had been in pain for three years, preventing her from running.

I’m happy to say in both cases the individual was able to be up and about in one case instantly, and in the other case it took 3 days for a complete reversal of the painful problem.

If you know anyone, anywhere in the world, who is in pain, please let them know that they can find a solution that isn’t offered by traditional pain-relief practitioners.  They can read more about it by going to www.FlexibleAthlete.com and searching on the shopping cart for Zoom Consultations.

Here’s To Your Health 

There is a tremendous amount of information on two of my websites: www.FlexibleAthlete.com and www.JulstroMethod.com.  I believe you’ll find a lot of answers by going through those sites, and by looking at the books and video programs that I’ve developed over the years.

There is a saying “God helps those who help themselves.”  These websites and my books are the tools you can use to help yourself to Treat Yourself to Pain-Free Living.

Wishing you well,

Julie Donnelly
