Will Fish Oil Lower Your Blood Pressure?

omgega-3 and blood pressureIs there a relationship between omega-3 and blood pressure we should understand to for health benefits?

High blood pressure is a killer! It can kill you by causing heart attacks, strokes, congestive heart failure, kidney failure and much more.

High blood pressure is a serial killer. It doesn’t just kill a few people. It kills lots of people. The American Heart Association estimates that high blood pressure directly or indirectly caused 363,000 deaths in 2010. That is almost 1 person every second and represents a 41% increase from 2000. It’s because high blood pressure is not a rare disease.

  • 31% of Americans have high blood pressure, also called hypertension, (defined as a systolic blood pressure of 140 mm Hg or more or a diastolic blood pressure of 90 mm Hg or more).
  • Another 30% of Americans have prehypertension (systolic blood pressure of 120-139 mm Hg or diastolic blood pressure of 80-89 mm Hg).

That’s over 61% of Americans with abnormal blood pressure!

High blood pressure is a silent killer. That’s because it is a very insidious disease that sneaks up on you when you least expect it. Systolic blood pressure increases 0.6 mm Hg/year for most adults over 50. By age 75 or above 76-80% of American adults will have high blood pressure.  Even worse, many people with high blood pressure have no symptoms, so they don’t even know that their blood pressure is elevated. For them the first symptom of high blood pressure is often sudden death.

Blood pressure medications can harm your quality of life. Blood pressure medications save lives. However, like most drugs, blood pressure medications have a plethora of side effects – including weakness, dizziness, fainting, shortness of breath, chest pain, nausea, diarrhea or constipation, heartburn, depression, heart palpitations, and even memory loss . The many side effects associated with blood pressure medications lead to poor compliance, which is probably why only 47% of patients with high blood pressure are adequately controlled.

You do have natural options. By now you are probably wondering whether there are natural approaches for controlling your blood pressure that are both effective and lack side effects. The answer is a resounding YES! I’ll outline a holistic natural approach for keeping your blood pressure under control in a minute, but let me start with the good news about omega-3 fatty acids.

 

The Good News About Omega-3 and Blood Pressure

omega-3s lower blood pressureWhat’s the good news about omega-3 and blood pressure?  We’ve known for some time that omega-3 fatty acids helped lower blood pressure, but two recent studies have really highlighted just how strong the effect of omega-3s on lowering blood pressure is.

The first study (Miller et al, American Journal of Hypertension, 27: 885-896, 2014) was a meta-analysis of 70 randomized, placebo-controlled clinical trials of long chain omega-3 (EPA + DHA) supplementation and blood pressure.

Here are the results of this study:

  • In the group with normal blood pressure at the beginning of the study EPA + DHA supplementation decreased systolic blood pressure by 1.25 mm Hg.
  • Given that systolic blood pressure rises an average of 0.6 mm Hg/year in adults over 50, the authors estimated that omega-3 supplementation alone would delay the onset of age-related high blood pressure by 2 years.
  • In the group with elevated blood pressure not taking medication at the beginning of the study, EPA + DHA supplementation decreased systolic blood pressure by an impressive 4.51 mm Hg and diastolic blood pressure by 3.05 mm Hg.
  • The authors noted that this decrease in systolic blood pressure could “prevent an individual from requiring medication [with all its side effects] to control their hypertension” or decrease the amount of medication required.

However, the doses of omega-3s used in these studies ranged from 1 to over 4 grams/day (mean dose = 3.8 grams/day). That sparked a second study (Minihane et al, Journal of Nutrition, 146: 516-523, 2016) to see whether lower levels of omega-3s might be equally effective. This study was an 8 week double-blind, placebo-controlled study comparing the effects of 0.7 or 1.8 grams of EPA + DHA per day (versus an 8:2 ratio of palm and soybean oil as a placebo) on blood pressure.

Here are the results of this study:

  • In the group with normal blood pressure at the beginning of the study, EPA + DHA supplementation caused no significant decrease in blood pressure. This could be due to the smaller number of subjects or the lower doses of EPA + DHA used in this study.
  • In the group with elevated blood pressure not taking medication at the beginning of the study, EPA + DHA supplementation decreased systolic blood pressure by 5 mm Hg and, the effect was essentially identical at 0.7 grams/day and 1.8 grams/day.
  • The authors concluded “Our data suggest that increased EPA + DHA intakes of only 0.7 grams/day may be an effective strategy for blood pressure control.”

A Holistic Approach To Blood Pressure Control

 

lower blood pressure dietThe latest information about omega-3 and blood pressure is good news indeed, but that’s not the only natural approach that lowers blood pressure. You have lots of other arrows in your quiver. For example:

  • The DASH diet (A diet that has lots of fresh fruits and vegetables; includes whole grains, low fat dairy, poultry, fish, beans, nuts and oils; and is low in sugar and red meats) reduces systolic blood pressure by 5-6 mm Hg. [Low sodium, low sodium/high-potassium, low-sodium/low-calorie, low-calorie and Mediterranean diets also lower blood pressure, but not by as much as the DASH diet].
  • Reducing sodium by about 1,150 mg/day reduces systolic blood pressure by 3-4 mm Hg.
  • Reducing excess weight by 5% reduces systolic blood pressure by 3 points.
  • Doing at least 40 minutes of aerobic exercise 3-4 times/week reduces systolic blood pressure by 2-5 mm Hg.

benefits of nitratesIf you’ve been keeping track, you’ve probably figured out that a holistic lifestyle that included at least 0.7 grams/day of long chain omega-3s (EPA + DHA) plus everything else in the list above could reduce your systolic blood pressure by a whopping 18-22 mm Hg.

That’s significant because,as the graphic on the right shows, the CDC estimates that reducing high systolic blood pressure by only 12-13 mm Hg could substantially decrease your risk of disease.

 

A Word Of Caution

While holistic approaches have the potential to keep your blood pressure under control without the side effects of medications, it is important not to blindly rely on holistic approaches alone. There are also genetic and environmental risk factors involved in determining blood pressure. You could be doing everything right and still have high blood pressure. Plus, you need to remember that high blood pressure is a silent killer that often doesn’t have any detectable symptoms prior to that first heart attack or stroke.

My recommendations are:

  • Monitor your blood pressure on a regular basis.
  • If your blood pressure starts to become elevated, consult with your doctor about starting with natural approaches to bring your blood pressure back under control. Doctors are fully aware of the side effects of blood pressure medications, and most doctors are happy to encourage you to try natural approaches first.
  • Continue to monitor blood pressure as directed by your doctor. If natural approaches are insufficient to bring your blood pressure under control, they will prescribe the lowest dose of blood pressure medication possible to get your blood pressure where it needs to be.
  • Don’t stop making holistic lifestyle choices to reduce blood pressure just because you are on medication. The more you do to keep your blood pressure under control, the less medication your doctor will need to use (That means fewer side effects).

 

The Bottom Line

 

  • Recent studies have shown that supplementation with as little as 0.7 grams of long chain omega-3s (EPA + DHA) per day is sufficient to decrease systolic blood pressure by ~ 5 mm Hg in people with untreated hypertension (high blood pressure). If your blood pressure is currently in the normal range, it is not yet clear how much EPA + DHA you need to keep it there. That may require a higher dose.
  • When you combine that with other natural approaches such as the DASH diet, reducing sodium, losing weight, and increasing exercise you can decrease blood pressure by 18-22 mm Hg.
  • The CDC estimates that is enough to substantially decrease your risk of stroke, coronary heart disease, memory loss, kidney disease, erectile dysfunction, death from cardiovascular disease, and death from any cause.
  • The authors of these recent studies concluded that holistic lifestyle changes including substantially increasing omega-3 intake have the potential to significantly delay the onset of age-related hypertension and may allow people with elevated blood pressure to eliminate or substantially reduce the use of blood pressure medications – with their many side effects.
  • High blood pressure is a silent killer. It is important to monitor your blood pressure regularly. If it becomes elevated, work with your doctor to find the balance of natural approaches and medication that is right for you.

Chronic Thigh Muscle Pain Relief

by

A Tale Of Two Olympic Rowers

Author: Julie Donnelly, LMT –The Pain Relief Expert

Editor: Dr. Steve Chaney

This blog post came about because I’ve been working with two incredible athletes who were in Sarasota to train, and then compete, to represent the USA in rowing at the lightweight division. Their quads were like rocks that were on fire. They really needed chronic thigh muscle pain relief.  It really made a difference when I treated their quads, and it showed during their qualifying competition. I’m happy to say, they WON!  They are going to Rio.

However, you don’t need to be an Olympic class athlete or a rower to suffer from chronic thigh pain. This treatment will work for anyone with thigh pain.

Chronic Thigh Muscle Pain Hampers Rowers

Thigh muscle pain can hamper a rower’s ability to powerfully force his/her body back as a key part of the rowing pattern.

Movements are done simultaneously: as the thigh muscles are pushing the seat back, the rower’s arms are pulling back on the oars.

It is the smooth interaction of the two movements that enable the rower to glide smoothly toward the finish line.

Chronic thigh muscle pain is caused by repetitive strain injury to the quadriceps muscle fibers.  As the fibers are forcefully contracting while the rower is straightening out his/her legs, knots are formed in the muscle fibers.

It is vital to force the knots out of the thigh muscles in order to release the tension that is being placed on the pelvis and knees, and to stop the pain.

To complicate matters, because of the muscle attachments to the bones and joints, the thigh muscle will also cause pain to be felt in the hip, low back, and knees.

Chronic Thigh Muscle Pain – Treatment That Works

This is an easy treatment to do, and one that uses a strange “tool” – a 12″ length of PVC pipe.

Start by sitting and holding the PVC pipe easily in your hands. Don’t grip it too tightly or you’ll end up hurting your forearm muscles.

chronic thigh muscle pain Begin at the top of your thigh muscle and press, don’t roll, all the way down to your knee.

The most important thigh muscle is called the Rectus Femoris .  (Go to #13 on graphic shown in this link)

This chronic thigh muscle pain is not only has pain caused by its own repetitive strain, but also because muscles in your low back can be rotating your pelvis and causes a domino-effect that shortens the muscle.

After you do 2-3 passes along the length of the muscle, stay on top of one of the spasms (you’ll feel the bumps as you go down your leg), and just press while slightly rotating the PVC pipe to force the knots out of the muscle fibers.

This treatment, and MANY others, is demonstrated in my book Treat Yourself to Pain-Free Living .  Or you can get the eBook version and an excellent, unique, stretching program that incorporates self-treatment with Yoga stretches by purchasing Focused Flexibility Training .

Thigh muscle pain, or any other muscle-joint pains, won’t go away on their own!  If you have pain, you need to be proactive and force the knots out of the muscles, and then safely stretch the fibers back to their proper length. It’s easy-to-do, and you’ll be amazed at how good you’ll feel after getting chronic thigh muscle pain relief or other muscle pain relief.

Wishing you well,

Julie Donnelly

Does Exercise Reduce Cancer Risk?

Another Reason To Stop Using Your Exercise Bike As A Clothes Rack

Author: Dr. Stephen Chaney

does exercise reduce cancer riskOK guys; listen up. We need to have a heart to heart talk about exercise. Sometimes it seems as if exercise is the step child of a healthy lifestyle.

Taking supplements is easy, and most of us can manage a healthy diet – when we think of it…

…but exercise – who has time?  Does exercise reduce cancer risk?

The more we learn, the more it looks like we should really make the time to exercise on a regular basis.

Does Exercise Reduce Cancer Risk?

A study reported several years ago in the British Journal of Cancer (98: 1864-1869, 2008) showed that moderate intensity exercise significantly reduces cancer incidence and decreases cancer deaths in men.

This study followed 40,708 Swedish men, aged 45-79,from 1998 to 2004.

cancer preventionWhen men who walked or cycled an average of 30 minutes a day were compared to men who exercised very little, there was a 5% (non-significant) decrease in the incidence of new cancer and a 33% increase in 5-year survival after cancer diagnosis!

When they looked at men who walked or cycled an average of 60 minutes a day, the 5-year survival after cancer diagnosis was about the same as for the men who were exercising for 30 minutes a day, but there was a statistically significant 16% decrease in the incidence of new cancer diagnosis compared to men who exercised very little.

A 16% decrease in new cancer diagnosis and a 33% increase in 5-year cancer survival after a cancer diagnosis – now that’s pretty significant!

What Does This Mean For You and Me?

exerciseIf you are a man, this study shows that moderate intensity exercise has the potential to decrease both your chance of developing cancer and your survival if you do get cancer – and as little as 30 minutes of exercise a day can make a difference.

But the sad fact is that less than 50% of the men in this country exercise for 30 minutes even 5 days a week- and 15% are bona fide couch potatoes.

So it’s time to dust off that exercise cycle or lace up your walking shoes and get moving.

If you are a woman, don’t think you are off the hook. Other studies have shown that regular exercise is just as beneficial in reducing cancer risk and increasing cancer survival in women.

So, does exercise reduce cancer risk?  The evidence in this study seems to say “yes.”

 

The Bottom Line

A study of 40,708 Swedish men showed that:

  • As little as 30 minutes/day of moderate intensity exercise increases your 5-year survival rate after cancer diagnosis by 33%.
  • If you up that to 60 minutes/day of moderate intensity, you not only increase your 5-year survival rate, but you also decrease your risk of developing cancer in the first place by 16%

If you are a woman, don’t despair. Other studies have shown that exercise is equally effective at decreasing cancer risk and improving cancer survival in women.

Teen Obesity and Heart Disease

by

Author: Dr. Stephen Chaney

teen obesity and heart diseaseI don’t need to tell you that we are in the midst of an obesity epidemic. Sadly, that obesity epidemic has even affected our children. Currently, one third of the adolescent population of the United States and other developed countries is overweight or obese, and those numbers are rapidly increasing.  Teen obesity and heart disease are not uncommon.

You probably also knew already that overweight and obesity in the early years increases the risk of death from cardiovascular disease and other causes among young adults, but a new study suggests that the consequences of overweight during the teen years may be much worse than we thought.

How Was This Study Done?

This study (Twig et al, The New England Journal of Medicine, DOI:10.1056/NEJMoa1503840, Published April 13, 2016) was based on a national database of 2.3 million Israeli adolescents ages 16-19 (average 17.1) for whom height and weight were measure between 1967 and 2010. Israel has such an extraordinarily large database because one year before military service all Israeli adolescents are required to undergo a medical evaluation. This is predominantly a male population because Orthodox women are excluded from service.

military studyIsrael also has a national health service that keeps a comprehensive database of deaths. Therefore, the investigators were able to record all deaths in this group that were attributable to coronary heart disease, stroke, sudden death from an unknown cause, or a combination of all three categories, which they classified as total cardiovascular deaths through June 30, 2011. That means that the median age at the end of the study was around 40.

The investigators divided the subjects into groups based on their BMI (weight (kg)/ height (m)2), a measure of the leanness or obesity of each individual and compared BMI with deaths due to various kinds of heart disease.

What sets this study apart from all previous studies was the size of the database (2.3 million). Because of the very large number of subjects in the study the investigators:

  1.  Were able to accurately measure the effect of BMI on cardiovascular deaths in people aged 30-40, an age at which the incidence of cardiovascular deaths is relatively low.
  2. Were able to divide the subjects into seven BMI groupings, rather than the two or three used in most previous studies.

For example, most previous studies have simply compared individuals who were obese (BMI > 95th percentile) or overweight (BMI in 85th to 94th percentile) with everyone in the normal range (BMI in the 5th to 84th percentile).

This study further separated individuals within the normal BMI range to high-normal (BMI in the 75th to 84th percentile), mid-normal (BMI in the 50th to 74thpercentile), and low normal (BMI in the 25th to 49th percentile) and compared each group to individuals with BMIs in the 5th to 24th percentile.

Teen Obesity and Heart Disease:  Will Your Teen Die Prematurely?

The results of the study were pretty sobering.

teen deaths from heart disease1)     For teens who are obese (210 pounds for a 6’ boy and 175 pounds for a 5’6” girl) at 17, their risk of dying prematurely from:

  • Heart attack increases 4.9 fold
  • Stroke increases 2.6 fold
  • All cardiovascular causes increases 3.5 fold
  • The increased risk of dying from all kinds of cardiovascular disease was 2-fold greater by age 27 and 4-fold greater by the time the subjects had reached age 37-47.

2)     For teens who are overweight (185-209 pounds for a 6’ boy and 155-174 pounds for a 5’6” girl) at 17, their risk of dying prematurely from:

  • Heart attack increases 3.0 fold
  • Stroke increases 1.8 fold
  • All cardiovascular causes increases 2.2 fold

3)     For teens who are at high-normal weight (175-184 pounds for a 6’ boy and 145-154 pounds for a 5’6” girl) at 17, their risk of dying prematurely from:

  • Heart attack increases 2.0 fold
  • Stroke increases 1.4 fold
  • All cardiovascular causes increases 1.8 fold

4)     Perhaps the most surprising finding was that even for teens who are at mid-normal weight (155-174 pounds for a 6’ boy and 130-144 pounds for a 5’6” girl) at 17, their risk of dying prematurely from:

  • Heart attack increase 1.5 fold
  • All cardiovascular causes increases 1.3 fold

5)     The number of teen girls in the study was much less, but they appeared to have similar increased risk of cardiovascular deaths with increased BMI compared to the boys in the study.

The message is clear on teen obesity and heart disease.

  • Obesity and overweight during the teen years are killers. They can lead to a significant increase in deaths due to heart attacks, strokes and all cause cardiovascular mortality long before those teens reach the age of 50.
  • Even teens who are in the higher end of what is considered a normal weight range are at increased risk of cardiovascular mortality long before they reach their golden years.

The Bottom Line

A recent study compared the BMI of 2.3 million Israeli teens (average age 17) with cardiovascular deaths over the next few decades

1)     Teens who were overweight or obese had a 2-fold greater risk of dying from cardiovascular disease by age 27 and 4-fold greater risk by the time they reached age 37-47.

2)     Even teens who were at the upper end of the normal weight range had a 1.8-fold increased risk of dying from cardiovascular disease.

The message is clear.

  • Obesity and overweight during the teen years are killers. They can lead to a significant increase in deaths due to heart attacks, strokes and all cause cardiovascular mortality long before those teens reach the age of 50.
  • Even teens who are in the higher end of what is considered a normal weight range are at increased risk of cardiovascular mortality before they reach their golden years.

The Benefits of Resveratrol

by

Author: Dr. Stephen Chaney

 

exerciseSome athletes, particularly Olympic athletes, are starting to use resveratrol to improve their workouts and their performance in events. Is their belief in the benefits of resveratrol justified, or is resveratrol just another of those “mythical” sports nutrition supplements? There have only been a few small studies on the subject, and those studies have been conflicting.

The study I am featuring this week (Polley et al, Appl. Physiol. Nutr. Metab. 41: 26-32, 2016) asked a more fundamental question. It asked whether resveratrol enhanced the effect of exercise on muscle mitochondrial capacity. For those of you who aren’t scientists that statement may require some interpretation.

What Are Mitochondria and Why Are They Important?

You can think of mitochondria as the power packs of the cell. They are tiny organelles that are found in most cells in our body. The foods that we eat contain a lot of energy (calories), but that energy is not in a form that our cells can use. Our cells metabolize those foods into small molecules that donate electrons to our mitochondria, and the mitochondria use those electrons to create energy in a form that our cells can utilize.

As you might imagine, mitochondria are particularly important for cells with high energy requirements, like our muscle cells. Those muscle cells responsible for endurance and high intensity (think gymnastics or weight lifting) exercise have the highest density of mitochondria and are the most dependent on those mitochondria for optimal performance.

Why Resveratrol Might Increase Muscle Mitochondrial Capacity?

mitochondriaMitochondria have a finite lifetime in our cells. As our cells age their mitochondria become less efficient and start doing bad things like releasing damaging free radicals into the cell. Exercise stress causes the mitochondria in our muscles to age more rapidly than the mitochondria in other cells. Fortunately, regular exercise also stimulates a pathway that causes production of new mitochondria and enhances their efficiency. Thus, the net effect of any exercise program is to increase both the number and efficiency of mitochondria, something referred to as mitochondrial capacity.

It turns out that resveratrol and a small group of related polyphenols also stimulate the same pathway. Animal and cell culture studies show that resveratrol can increase muscle mitochondrial capacity. However, since resveratrol and exercise increase mitochondrial capacity by the same mechanism, the question is whether resveratrol has any added benefit over exercise alone. That is the question this study was designed to answer.

The Benefits of Resveratrol on Muscle Mitochondrial Capacity?

Previous studies had suggested that one of the benefits of resveratrol might be increasing muscle mitochondrial capacity for people who have engaged in relatively little physical activity in the past. For examples, studies have shown that resveratrol activates the pathway leading to increased mitochondrial capacity in obese and diabetic populations, both groups that may not have been involved in regular exercise. In contrast, other studies found no enhancement of those same pathways compared to exercise alone in more highly trained populations involved in high intensity training.

benefits of resveratrolBased on those results, the present study (Polley et al, Appl. Physiol. Nutr. Metab. 41: 26-32, 2016) was specifically designed to assess the effect of resveratrol supplementation along with low-intensity exercise in an untrained muscle group. The authors recruited healthy young adults with approximately equal numbers of men and women. To assure that the muscle group was relatively untrained, they asked the subjects to perform wrist flexor exercises in their non-dominant arm. They excluded from the study anyone whose exercise regimen involved regular use of the non-dominant forearm such as rowing, rock climbing or CrossFit.

This was a double-blind, placebo-controlled study. Half of the group received 500 mg of resveratrol and the other half received the placebo. The placebo group served as a control for the effect of exercise alone. The dominant arm was not exercised, so it served as a control for the effect of resveratrol alone. The participants took resveratrol or placebo upon wakening each morning. The wrist flexor exercises were performed 3 times per week for 4 weeks. Mitochondrial capacity measurements were made using near infrared spectroscopy on a weekly basis.

The results were pretty straight-forward.

  • Low-intensity training alone (placebo group) for 4 weeks resulted in a 10% increase in mitochondrial capacity.
  • Low-intensity training plus resveratrol for 4 weeks resulted in a 40% increase in mitochondrial capacity. This represented a highly significant difference between the resveratrol and placebo groups.
  • Neither the resveratrol group or the placebo group exhibited changes in the untrained arm, which suggests that resveratrol without exercise has little or no effect on mitochondrial capacity in young, healthy subjects.

The authors concluded: “Taken together, these findings indicate that [the] combination of exercise and resveratrol is needed for eliciting maximal muscle mitochondrial adaptations to low-intensity training programs.”

What Are the Strengths and Weaknesses of This Study?

Strengths:Because previous studies had suggested that the effects of resveratrol might be masked in highly trained individuals or by high intensity exercise, this study was specifically designed to look at the effects of resveratrol on mitochondrial capacity when administered along with low-intensity exercise in untrained muscles. In that sense this study breaks new ground and suggests that, under the right conditions, resveratrol can enhance exercise training.

Weaknesses:The weaknesses of this study were many:

  • It was a very small study. That is not unusual in this area of research, but clearly much more research is needed.
  • It used a higher dose of resveratrol than previous studies. However, plasma levels of resveratrol were not determined and the effect of lower doses was also not determined, so we have no idea how much resveratrol is actually needed to elicit this response.
  • While increased mitochondrial capacity is a probable predictor of improved exercise efficiency, no performance outcomes were actually measured. Most people probably don’t care how well their mitochondria work. They care about how well their muscles perform.

What Does This Mean For You?

We are in the very early stages of research into the benefits of resveratrol on exercise. Many more studies are needed before we will be in a position to fully understand the effects of resveratrol on exercise efficiency and performance outcomes. This and previous studies suggest that resveratrol is likely to be most effective at enhancing exercise efficiency with low intensity exercise in relatively untrained muscles.

If true, that would mean resveratrol might be helpful for the millions of Americans who are “weekend warriors” or exercise sporadically. It may even be beneficial for those of us who exercise regularly at a low to moderate intensity level.

However, because resveratrol and exercise improve mitochondrial capacity by the same mechanism, previous studies suggest that resveratrol might be a less effective addition for highly trained athletes engaged in high-intensity exercise.If true, this would put resveratrol in the same category as several other popular exercise supplements such as arginine and citrulline that also appear to be more effective for untrained individuals than they are for highly trained athletes.

However, I am aware of many Olympic athletes who use and swear by a resveratrol polyphenol blend. It could be placebo, but it could also suggest that resveratrol does enhance performance for highly trained athletes engaged in high-intensity exercise. As I said at the beginning of this section, there is much more research to do. That’s what makes science so much fun. There are always new things to learn.

 

The Bottom Line 

We are in the very early stages of research into the benefits of resveratrol on exercise. Many studies will be needed before we will be in a position to fully understand the effects of resveratrol on exercise efficiency and performance outcomes. However, a recent study is of interest because it introduces a new perspective to our understanding of the possible effects of resveratrol on exercise efficiency.

  • Thisstudy reports that resveratrol significantly enhances the increase in mitochondrial capacity caused by low-intensity exercise in untrained muscles
  • If true, that would mean resveratrol might increase exercise efficiency for the millions of Americans who are “weekend warriors” or exercise sporadically. It may even be beneficial for those of us who exercise regularly at a low to moderate intensity level.
  • However, because resveratrol and exercise improve mitochondrial capacity by the same mechanism, previous studies suggest that resveratrol might be a less effective addition for highly trained athletes engaged in high-intensity exercise.
  • If true, this would put resveratrol in the same category as several other popular exercise supplements such as arginine and citrulline that also appear to be more effective for untrained individuals than they are for highly trained athletes.
  • However, I am aware of many Olympic athletes who use and swear by a resveratrol polyphenol blend. It could be placebo, but it could also suggest that resveratrol does enhance performance for highly trained athletes engaged in high-intensity exercise.

As I said before, there is much more research to do. That’s what makes science so much fun. There are always new things to learn.

Chronic Neck Pain and Headache Relief

Chronic Neck Pain and Headaches Can Ruin Your Day

neck pain and headacheActually, chronic neck pain and headaches will do more than ruin your day.It can interfere with your daily activities and cause you to stop doing the things you enjoy. If you are an athlete, it can cause you to slow down so much that you stop doing all the sports you enjoy, and can have a serious impact on your career.

Yet, when the medical profession is searching for solutions to chronic neck pain and headaches, muscles are rarely considered.  This is a major oversight.  In fact, muscles cause a high percentage of chronic headaches, and almost all neck pains.  The good news is, they are relatively simple to self-treat successfully!

First let’s take a look at your neck so it will be clear why muscles can cause chronic headaches.

Your cervical vertebrae start at the base of your skull. C1 is called “the Atlas” because it holds up your skull just as Atlas held up the world.

spineC2 has a bone in it that comes through the center of C1. The bone is called the “dens” and your skull sits on the point of it.  It is because of this arrangement that you can turn your head left and right.

These two vertebrae are key to chronic headaches that are so severe they can be blinding.

Take a look at the muscle that is labeled “levator scapulae.”  Nicknamed “the shrug muscle,” because it lifts up your shoulders, it originates on C1-4, although the greatest problem is with the C1-2 points.  As your levator scapulae muscle gets tight, it pulls the two vertebrae to the side and down.  This causes the bone to press into your spinal cord at the very base of your skull where it exits from your brain and begins its journey down to your tailbone.

The bone pressing into your spinal cord will cause horrific chronic headaches.  And, as the muscle is also putting a strain on your shoulder, you will feel pain and tension right where your neck meets the top of your shoulder.

Chronic Headaches Can Be Caused By Poor Posture

Chronic headaches are often caused by a posture that is common lately because of looking down at our cell phones and computers.

Notice the graphics on the left, and then imagine the 42 lb head on the right not only putting a strain on the entire cervical spine, but since you are looking down, it is also having the heavy skull putting a twist onto the first two cervical vertebrae.

You can imagine what is happening to your spinal cord under these circumstances. The pressure is severe, and a chronic headache will result.

Chronic Neck Pain and Headache Treatment That Works

Here is a two-step Julstro self-treatment method that works. First lean your head back and grasp the muscle at the back of your neck.

neck pain treatmentThis is easier to do when you have a headache as it will be thick and tight, but if you want to work at preventing a chronic headache, you’ll need to move your head around so the muscle can be felt.

If you don’t have a headache, just take your flat fingertips and press directly into the muscle fiber.  Hold the pressure for 30 seconds, let go, and then press again.

Next take the three middle fingers of your opposite hand (ie: If you are treating the left side of your neck, use the three fingers on your right hand and press directly into your tight muscle.)

Hold the pressure for 30 seconds and then just move 1-finger width down the muscle and start over again.

chronic neck pain and headache reliefGo from the base of your skull all the way to the top of your shoulder.  If you have a chronic headache, the muscle will stand out and you’ll have no problem finding it.

Work on both sides of your neck, even if the chronic headache pain is only on one side of your head.

Stretch the muscles by holding the pressure on the muscle and then bringing your head down toward your chest.

Follow these steps for chronic neck pain and headache relief.

Wishing you well,

PAHs Contaminate Supplements?

by

Do Your Supplements Contain Carcinogens?

Author: Dr. Stephen Chaney

 

pahs in supplementsMost of us take supplements to improve our health. We count on those supplements being pure and effective. We don’t expect the supplements we take to contain carcinogenic (cancer causing) contaminants. However, that expectation appears to be unfounded. A recent study found that 72% of supplements tested were contaminated with a particularly dangerous class of cancer causing chemicals called polycyclic aromatic hydrocarbons (PAHs)

Where Do PAHs Come From  andWhy Are TheyDeadly?

Polycyclic aromatic hydrocarbons (PAHs) are produced by incomplete combustion of organic materials. Major environmental sources of PAHs are incomplete burning of gasoline, coal and other fuels. Unfortunately, automobile exhaust, coal burning power plants, and exhaust from factories are almost ubiquitous in today’s world, resulting in significant PAH contamination of our air, water, and soil. The unfortunate truth is that we all live in an increasingly dirty and toxic environment.

pahs can come from highwayAs you might imagine, cigarette smoke is the #1 source of PAHs in humans. However, foods are a major route for PAH exposure in humans as well. There are many food sources of PAHs. For example,

  • Grilling, roasting and frying foods, especially meats, at high temperatures creates PAHs.
  • Smoking fish or meats creates PAHs.
  • Barbecuing meats creates PAHs.
  • Even plant-based foods can contain PAHs if the soil, air or water they were grown in was contaminated.
  • PAHs can be introduced into supplements if any of their ingredients are dried at high temperatures as part of the processing procedure.

By now you are probably realizing that it is not just our environment that is increasingly being contaminated with PAHs. We are all becoming contaminated with PAHs as well. Our bodies are becoming toxic waste dumps.

Unfortunately, PAHs are not innocuous chemicals. Perhaps the best studied and deadliest of the PAHs is a compound called benzo[a]pyrene. It is classified as a class 1 carcinogen and mutagen by the IARC (International Agency for Research on Cancer). Perhaps some explanation is in order:

  • The IARC is an international organization that is charged with evaluating the scientific evidence for the carcinogenicity of various chemicals. It also sets upper limits for safe exposure to those chemicals.
  • Class 1 carcinogens are compounds that the IARC has classified as definitely carcinogenic to humans. Simply put, the IARC considers the scientific evidence to be overwhelming that those compounds are carcinogens.

To date only 118 compounds have been blacklisted by the IARC as class 1 carcinogens and benzo[a]pyrene is one of them. However, many of the other, less studied, PAHs are classified as probable carcinogens by the IARC.

Unfortunately, in most countries of the world (including the United States), PAH limits in food and supplements are unregulated. Because they are unregulated, many supplement companies don’t even test for them. That is unfortunate because a recent study shows that many supplements are contaminated with high levels of PAHs, and their manufacturers didn’t even know it.

Do Your Supplements Contain PAHs or Other Carcinogens?

carcinogens in supplementsThe European Union has taken the lead in regulating PAH levels. They have used the IARC guidelines to create upper allowable limits for PAHs in food and supplements. Separate standards were set for benzo[a]pyrene and the total of the four most common PAH contaminants (benzo[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthrene, and chrysene). Those new regulations just went into effect April 1st 2016.

To gauge the impact of these new regulations on the supplement industry, the EU asked the European Union Reference Laboratory to measure the levels of PAH contamination in supplements sold in the EU prior to the implementation of the new regulations. Because vitamin and mineral supplements are seldom contaminated with PAHs, they were excluded from the study.

The EU Reference Laboratory started collecting a wide range of herbal and botanical supplements, fish and edible oil food supplements, and propolis and other bee supplements sold in the EU in 2013. The Reference Laboratory analyzed 94 different supplements for PAH contamination, and the results of these analyses were published in October 2015 (Z. Zelinkova and T. Wenzyl, Food Additives & Contaminants: Part A, 32: 1914-1926, 2015).

[In case you, like me, were wondering what propolis is, it is a resin like substance that bees use as a glue to hold their hives together. WebMD states that it may have some use as a topical agent for cold sores, genital herpes, and after mouth surgery, but that any other uses are unproven. However, if you visit websites for propolis products you find it in capsules and liquids for internal consumption. You are told that it cures bacterial and fungal infections, cures viral infections like AIDs, cures cancer, and removes warts.]

The results of their analysis were pretty scary:

  • 72% of the supplements tested exceeded EU limits for the four most common PAH contaminants, and 52% exceeded EU limits for benzo[a]pyrene.
  • Propolis and spirulina were the most heavily contaminated supplements. Valerian and St. John’s Wort had moderately high levels of contamination, and some samples of bee pollen, sea buckthorn oil, barley greens, Echinacea, and Ginko far exceeded EU standards.
  • If consumers took the recommended dosage of the two most contaminated products (Premium Spirulina and Propolis Intense) they would more than double their daily intake of PAHs and far exceed what the IARC considers safe.
  • Fish oils generally had low levels of PAH contamination. The authors speculated this may be because fish have the ability to metabolize PAHs. However, other edible oils, particularly sea buckthorn oil and a mixture of garlic oil with soybean and sunflower oils did exhibit significant PAH contamination. The authors speculated that this PAH contamination may have been introduced during the processing of these oils.

Why The PAH and Contamination Problem Is Worse Than You Thought

worseYou might be thinking what could be worse than 72% of supplements being contaminated with cancer causing PAHs? Here is some food for thought.

  • PAHs are just the tip of the iceberg. Many supplements are also contaminated with PCBs and heavy metals. For example:
  • Fish oil is often contaminated PCBs.
  • Rice protein and other rice-derived ingredients are often contaminated with lead and/or mercury.
  • The US regulates PAHs in our water supply, but does not currently regulate PAHs in our supplements. That means that manufacturers that make products primarily for consumption in the US have no incentive to test their products for PAH contamination. Most of them have no idea whether their products are safe or not.
  • There is no guarantee that even products labeled Certified Organic and Non-GMO are free of PAH contamination. For example:
  • Organic certification just means that the crop was raised using organic methods. No analysis of purity is required to assure that the crop had not been inadvertently contaminated. The same is true of non-GMO certification. No analysis of purity is required.
  • Organically grown, non-GMOcrops that are used as ingredients for supplements can still be contaminated if the air, soil or water is contaminated from any nearby pollution source. For example, ground water pollution is the major source of the heavy metal contamination often seen in rice-derived ingredients.
  • Organically grown, non-GMO crops can even become contaminated by PAHs if they are grown next to a busy highway.
  • Even if the ingredients are pure to begin with, PAH contamination can be introduced during processing.

What does all of this mean to us? It means that it is absolutely imperative that we do our due diligence and only choose supplement manufacturers whose quality control standards far exceed what is required of the industry. Our health just may depend on it.

 

The Bottom Line

 

  • A recent study has reported that 72% of herbal and botanical supplements, fish and edible oil food supplements, and supplements derived from bees sold in the EU were contaminated with high levels of cancer causing polycyclic aromatic hydrocarbons (PAHs).
  • The levels of PAHs in many of these products far exceeded standards recently enacted by the EU. If those supplements were taken as recommended, the daily intake of PAHs by people consuming them would also far exceed the safe limits of exposure to these toxic chemicals set in place by the International Agency for Research on Cancer.
  • While all of this sounds bad enough, the news is even worse for most of us living in the US.
  • PAHs are just the tip of the iceberg. Many supplements are also contaminated with PCBs and heavy metals.
  • The US regulates PAHs in our water supply, but does not currently regulate PAHs in our supplements. That means that manufacturers that make products primarily for consumption in the US have no incentive to test their products for PAH contamination. Most of them have no idea whether their products are safe or not.
  • There is no guarantee that even products labeled Certified Organic and Non-GMO are free of PAH contamination.
  • What does all of this mean to us? It means that it is absolutely imperative that we do our due diligence and only choose supplements manufacturers whose quality control standards far exceed what is required of the industry. Our health just may depend on it.  Remember, PAHs are not the only potential problem.

Can Supplementation Improve Teen Behavior?

by

Author: Dr. Stephen Chaney

 

can supplementation improve teen behaviorAll teenagers can be a handful at times. Experts tell us that their raging hormones are to blame, but could their junk food diets play a role as well? If so, would something as simple as supplementation improve teen behavior?

This has been a controversial issue, with some studies saying yes and other studies saying no. With that in mind I thought I would share a recent study that concludes supplementation may improve behavior in teens. While this one study will not resolve the controversy, it does provide some insight into why the results of previous studies have been so contradictory.

Can Supplementation Improve Teen Behavior?

This study (Tammam et al, British Journal of Nutrition, 115: 361-373, 2016) enrolled 196 healthy teens aged 13-16 from a large public school in London. The school was located in an economically depressed area of London where a large proportion of the adults were out of work and had no formal education. Many of the children attending that school had adverse home environments and poor nutrition.

This is an important point. The scientists running the study had specifically chosen a teenage school population that was likely to have poor nutritional status. This poor nutritional status was confirmed by blood samples taken at the beginning of the study which showed the teens were low in iron, folate, vitamin D, vitamin C and omega-3 fatty acids – all of which are important for brain health.

teen behvaviorThe students were given either a comprehensive multivitamin plus 541 mg of omega-3 fatty acids (containing 165 mg EPA and 116 mg DHA) or matched placebos for one school term (12 weeks). The study was fully blinded in that neither the students nor their teachers knew who had received the supplements and who had received the placebo.

Blood test taken at the end of the study showed that students taking the supplements had significantly higher blood levels of folate, vitamin C, vitamin D, and omega-3 fatty acids (iron levels remained unchanged) while those nutrient levels were unchanged in the placebo group.

Teachers rated the student’s behavior using the Connors Clinical Index Teacher Rating Scale before the study began and again during the last week of the study. The results were clear cut. Behavior improved in the group receiving the supplements and worsened in the group receiving the placebo.

The researchers also looked at disciplinary infringement logs (you can think of those as disciplinary problems severe enough to send the kids to the principal’s office), but the number of disciplinary incidents per child were too low to draw any statistically significant conclusions.

Why Are Supplementation and Teen Behavior Studies So Contradictory?

diet and behaviorAs I said at the beginning of this article, previous nutritional intervention trials looking at teen behavior problems have been conflicting. Some, like this study, have shown a clear benefit of supplementation on teenage behavior. Others have shown no benefit at all.

Most experts tend to treat all studies on a particular topic as equal. They throw all of the studies into a statistical pot and look at the average effect. When studies are contradictory, as is the case for studies looking at the effect of supplementation on teenage behavior, the positive and negative studies cancel each other out and the net effect is often close to zero. When that happens experts generally consider the intervention as “unproven”.

That is a valid approach, but I also like to look for patterns. I like to ask why the studies have come to such contradictory conclusions.

When you evaluate the studies on supplementation and teenage behavior carefully, a pattern starts to emerge. If most of the teenagers in the study have poor nutritional status or have severe behavior problems (such as teenagers in prison), the studies generally show a benefit of supplementation. If most of the teens in the study have good nutritional status at the beginning of the study, the results of supplementation are very difficult to detect. Similarly, if most of the teens in the study are well behaved to begin with, supplementation appears to have little effect.

What Does This Mean For Your Teenager(s)?

The causes of teenage behavior problems are many. Poor nutrition may play a significant role, but genetics, hormones, home environment and school environment are important as well. However, teen eating habits are often less than ideal. If you have a teenager with behavior problems and poor eating habits, supplementation is an inexpensive intervention that may just contribute to better behavior.   So, can supplementation improve teen behavior?  Maybe.

 

The Bottom Line

  • The study was performed in an economically depressed school district where many children suffered from poor nutritional status. Blood test taken at the beginning of the study showed that the students were low in iron, folate, vitamin C, vitamin D, and omega-3 fatty acids. Blood tests taken at the end of the study showed improved nutritional status for every nutrient except iron in the group taking supplements.
  • When you combine this study with previous studies, a pattern emerges.  If most of the teenagers in the study have poor nutritional status or have severe behavior problems (such as teenagers in prison), the studies generally show a benefit of supplementation. If most of the teens in the study have good nutritional status at the beginning of the study, the results of supplementation are difficult to detect. Similarly, if most of the teens in the study are well behaved to begin with, supplementation appears to have little effect.
  • What does all of this mean to the general public? Nutritional status is just one component of teenage behavior. Hormones, genetics, home environment and school environment are important as well. However, teen eating habits are often less than ideal. If you have a teenager with behavior problems and poor eating habits, supplementation is an inexpensive intervention that may just contribute to better behavior.

Are Seniors Taking Too Many Medications?

The Dangers of Polypharmacy

Author: Dr. Stephen Chaney

 

seniors taking too much medicationModern medicines are truly miraculous. They control the  symptoms associated with many major diseases. At their best they  save lives. But have we become too reliant on medications to cure  everything that ails us?

Every medication has side effects, and many medications interact  with each other in harmful ways. That has become a major concern for our senior citizens because many of them end up on 5 or more medications, something the  medical profession refers to as polypharmacy.

Why Are Seniors Taking So Many Medications?

It starts innocently enough:

  • antioxidant aging Your cholesterol edges up a bit, and your physician recommends  that you go on a statin to reduce your risk of a heart attack. This  is in spite of the fact that it has been almost impossible to prove  that statins actually decrease heart attack risk in people who  have not yet had a heart attack (See “Do Statins Really Work?”  (https://www.chaneyhealth.com/healthtips/cholesterol‐lowering‐ drugs‐right/) and “Does An Apple A Day Keep Statins Away?”  (https://www.chaneyhealth.com/healthtips/apple‐day‐keep‐statins‐ away/))
  •  Sometimes your cholesterol may not even be elevated. In today’s world statins are often recommended if you are over a certain  age, are overweight, and have some other risk factor such as pre‐ diabetes or high blood pressure.
  •  Your blood pressure starts to inch up (something that happens to most people as they get  older), and your physician recommends one or two blood pressure medications.
  •  Your blood sugar gets a bit high, and your physician recommends a drug to control your  blood sugar to prevent your pre‐diabetes from turning into diabetes.
  •  Perhaps you develop a minor arrhythmia (something else that often happens as we get  older), and your physician recommends one drug to control your heart’s rhythm and  another drug to thin your blood.

Before you know it you are on several medications. As if that weren’t bad enough, each of these  medications has side effects, so you often need to add other medications to control the side effects  of the original medications. For example:

  •  Perhaps you develop heartburn, gas, and/or bloating from the statin, so your physician recommends a drug to control those side effects.
  •  Perhaps you develop headaches, depression, or g.i. symptoms from your blood pressure medication, and your physician gives you one or more drugs to control those symptoms.

I could go on, but I think you get the point. It is easy for senior citizens to end up on multiple  medications. The question is whether that is a good thing or a bad thing.

Are Seniors Taking Too Many Medications?

are supplements dangerousA recent study (Qato et al, JAMA Internal Medicine,  doi:10.1001/jamainternmed.2015.8581, published online March 21, 2016) shows just how big a problem this has  become. The authors conducted a longitudinal, nationally  representative sampling of community‐dwelling adults  aged 62 to 85 years old. They conducted in‐home  interviews that included medication inspections with  2351 participants in 2005‐2006 and again with another  2206 participants 5 years later in 2010‐2011.  The results were startling:

  •  Simultaneous use of at least 5 prescription medications increased from 30.6% in 2005‐ 2006 to 35.8% in 2010‐2011.   That is a 17% increase in just 5 years!
  •  The percentage of adults using medication combinations with the potential for major drug‐ drug interactions increased from 8.4% in 2005‐2006 to 15.1% in 2010‐2011.   That’s almost double in just the last 5 years! To put that into perspective, it means that almost 1 out of every 6 seniors in this  country is at risk of major drug‐drug interactions.
  •  Most of those dangerous interactions were due to physician prescribed medications,  although interactions with over the counter medications also contributed to the total.

The authors of the study concluded “These findings suggest that unsafe use of multiple  medications is a growing public health problem.”

The Most Dangerous Drug­-Drug Interactions

The problem is that these drug‐drug interactions aren’t minor  inconveniences. They can kill you. Here are some of the more  dangerous drug‐drug interactions the authors listed:  Let’s start with those drug‐drug interactions for physician‐ prescribed medication.

  •  Statins used in combination with some blood pressure  medications or with Coumadin can lead to excessive  bleeding, muscle damage and kidney failure.
  •  The combination of those same blood pressure medications with anti‐platelet blood  thinning medications like Plavix dramatically increases the risk of a heart attack and death.

DangerAnd, it’s not just interactions of physician‐prescribed drugs that are of concern. Interactions  between physician‐prescribed drugs and over the counter medications can be equally dangerous.

These interactions are particularly insidious because patients often don’t tell their doctors about  over the counter medications they are using. For example:

  •  The combination of blood thinners with pain relievers such as aspirin or Aleve generally  leads to excessive bleeding.
  •  However, the combination of certain anti‐platelet blood thinning medications such as  Plavix and either pain medications like Aleve or acid reflux medications like Prilosec can  have the opposite effect – causing blot clot formation (such as deep vein thrombosis)  which can lead to heart attacks and cardiovascular death.

Is There a Better Way?

age-related muscle lossIn an editorial that accompanied this study (JAMA Internal  Medicine, doi:10.1001/jamainternalmedicine.2015.8597)  Dr. Michael A, Steinman said “There are many older adults  who would be healthier if they threw away half of their  medications. Yet, there are people with multiple chronic  diseases who can benefit from multidrug therapy…We  [currently] do not have methods that allow us to reliably  evaluate medication therapy…for the outcomes that really  matter, namely whether a drug is actually helping the  patient, causing adverse effects, or is necessary at all.”

If your doctor doesn’t really know for sure whether the medications you are taking help you, hurt you, or have no effect, you might be wondering whether  there is a better way. The answer is a clear YES!

  •  Multiple studies have shown that lifestyle change is more effective than medications for  keeping blood pressure under control (for example: Guzman‐Castillo et al, BMJ Open,  doi:10.1136/bmjopen‐2014‐006070).
  •  Studies have also shown that lifestyle change is more effective than medications for  controlling diabetes (for example: Knowler et al, New England Journal of Medicine, 346:  393‐403, 2002).
  •  The evidence for heart disease is so strong that both the National Institutes of Health and  the American Heart Association recommend that a little TLC (Therapeutic Lifestyle  Change) be tried before resorting to statins and other medications to lower cholesterol and reduce heart attack risk (http://www.nhlbi.nih.gov/health/resources/heart/cholesterol‐ tlc).

Fortunately, you don’t need different lifestyle changes for different diseases. One size fits all!  I  have talked about a healthy lifestyle in great detail in past issues of “Health Tips From the  Professor.”  In brief, a healthy lifestyle consists of a  mostly plant‐based diet with healthy fats, healthy carbohydrates, and healthy proteins. Then add  in exercise, weight control, and appropriate supplementation and you have a winning  combination.

Why risk the dangers of multiple medications when there is a better way?

The Bottom Line

  1.  A recent study has clearly demonstrated that the use of multiple medications in senior  citizens aged 62 and older is starting to reach dangerous levels. Between 2005 and 2010:
    •  The percentage of seniors using 5 or more medications has increased from 30.6% to  35.8%. That’s a 17% increase in just 5 years.
    •  The percentage of seniors using medication combinations with the potential for  major drug‐drug interactions has increased from 8.4% to 15.1%. That’s almost  double and represents 1 out of every 6 senior citizens.
  2. These dangerous drug interactions aren’t trivial. They include excessive bleeding, heart  attack and stroke, renal failure and death, just to name a few.
  3.  There is a better way. Studies have shown that lifestyle change is more effective than  medication at controlling many chronic diseases such as heart disease, high blood pressure,  and diabetes. Lifestyle change has no side effects and no dangerous interactions. More  importantly, you don’t need different lifestyle changes for different diseases. One size fits  all! I have talked about a healthy lifestyle in great detail in past issues of “Health Tips From  the Professor” (https://www.chaneyhealth.com/healthtips). In brief, a healthy lifestyle  consists of:
    •  A mostly plant based diet that includes healthy fats, healthy carbohydrates, and  healthy proteins.
    •  Exercise, weight control, and appropriate supplementation.
  4.  So if you or someone you love are taking multiple medications, talk with your doctor about  the lifestyle changes that you are willing to make. Most doctors would be delighted to  reduce the medications you are taking if you are willing to do your part.

Exercise and Weight Loss

by

Author: Dr. Stephen Chaney

exercise and weight lossAre you confused yet?  Just as you were starting to wrap your mind around the current consensus recommendations that we engage in 30 minutes of moderate intensity exercise 5 days/week, news stories are starting to appear saying that might not be enough exercise if you want to lose weight!

So how much exercise DO you need, and why is there so much confusion with exercise and weight loss?

Let me start by reviewing a couple of studies that appeared a few years ago on weight loss in middle aged, overweight women.

 

Exercise and Fat Loss

The first study looked at the effect of exercise intensity on abdominal fat loss over a 16-week period(Irving et al, Medicine & Science In Sports & Exercise,40: 1863-1872, 2008).

The women in this study were divided into three groups:the control group that just continued their normal exercise pattern (little or none), a group that engaged in supervised moderate intensity exercise 5 days per week, and a group that engaged in supervised, high intensity exercise 3 days per week and moderate intensity exercise the other two days.

The diet was identical for all three groups and the calories expended by exercise were also identical (the high intensity exercise was performed for shorter periods of time so that the calories expended were the same).

The results were striking. Weight loss was similar in the two exercise groups (calories do count). However, the women in the high intensity exercise group lost a significant amount of abdominal fat while the other two groups did not! As you may know, abdominal fat appears to be much more damaging metabolically than fat stores in other parts of our bodies.

 

Exercise and Weight Loss

woman runningThe second study looked at the effect of exercise duration on weight loss over a 24-month period (Jackcicet al, Archives of Internal Medicine, 168: 1550-1559,2008).

In this case the diet and the intensity of the exercise(moderate intensity) were the same. The difference was in the duration of the exercise. In this case the calories expended by exercise was not kept the same. The group that exercised for longer burned significantly more calories than those who exercise for a shorter time.

Again the results were striking. Only those study participants who exercised for at least 275 minutes/week (an average of almost 60 minutes a day for 5 days) were able to lose 10% or more of their weight and keep the weight off over a 24-month period.

 

How Much Exercise is Enough?

So what does all of this mean to you?

how much exercise is enoughWhen most Americans decide to shed a few pounds, one of the first things they think of is getting more exercise. After all, it’s much easier to walk around the block during lunch hour than to actually change what you are eating.

The question then becomes how much exercise is enough? Is the recommended 30 minutes a day of moderate intensity exercise 5 days per week enough?

If you actually work through the math, it is pretty easy to guess that it might not be enough. For example, a recent study looked at how much moderate intensity exercise would be required for a 155-pound woman to burn off the calories in same popular fast foods. For example, to burn off the calories:

  • In a MacDonald’s Big Mac, she would need to cycle at a moderate pace for 1 hour.
  • In an Arby’s Reuben, she would need to walk at a moderate pace for 3 hours.
  • In a Super Sonic Double Cheeseburger with Mayo, she would need to do low impact aerobics for 3 hours.

Of course, if she had fries and a soda with any of those meals she would need to do even more exercise.

weight loss and dietThese estimates are not just hypothetical. The studies described above clearly show that if you are relying on exercise alone to shed your excess pounds and/or excess fat, you are going to need higher intensity exercise and/or longer duration moderate intensity exercise than the current consensus recommendations suggest.

In other words, the current recommendations of 30 minutes of moderate intensity exercise 5 days per week probably won’t make much of a dent in your weight unless the exercise is coupled with a very good weight loss program.

But, if you have ever relied on exercise alone for weight loss, you have probably guessed that already!

Of course, the consensus recommendations are still valid for what they were designed to accomplish. 30 minutes a day of moderate intensity exercise 5 days per week is sufficient to improve fitness and reduce cardiovascular risk factors.  And fitness reduces your risk of disease even if you are still overweight.

Furthermore, since many Americans probably don’t get even 30 minutes of exercise in a week, 30 minutes 5 days per week is a great starting goal.

 

The Bottom Line 

Recent studies show that the current recommendations of 30 minutes of moderate intensity exercise 5 days per week probably won’t make much of a dent in your weight unless the exercise is coupled with a very good weight loss program.

Don’t freak out about all of the conflicting exercise recommendations. Here’s what I suggest:

1) Consult with your physician before you start any exercise program.

2) Get active. Start slowly and start by choosing activities that are fun and accessible to you.

3) Set your goal of 30 minutes of moderate intensity exercise 5 days per week. If you want to lose weight, couple that with a well-designed weight loss program.

4) If your combination of exercise and diet isn’t putting a dent in your weight and weight loss is important to you, pick up the pace or increase the duration of exercise.
