~ Metabolic Syndrome: The Twenty-First Century Epidemic - Program

A Program for Averting Metabolic Syndrome

The following step-by-step program can help you avert the potentially deadly consequences of metabolic syndrome. Taking these simple steps can help you lead a long, healthy life and avoid succumbing to a multitude of life-threatening diseases.

Step 1: Assess Your Body Composition.

The first step involves knowing and understanding your body composition and its importance in helping to prevent metabolic syndrome. Surprisingly, stepping on a scale and seeing what you weigh does not tell very much about your risk of developing metabolic disease.

Body mass index (BMI) is a standard measure of overweight and obesity. BMI is obtained by dividing your body weight in kilograms by your height in meters squared (kg/m2). However, BMI fails to account for body composition. Your body composition is a measure of how much lean body mass (muscle) and adipose tissue (body fat) you have.

Compare two 40-year-old men, both of whom stand six feet tall and weigh 200 pounds. One man is very muscular (about 7% body fat) and has a waist circumference of 32 inches. By contrast, the other man is out of shape (about 30% body fat) and has a waist circumference of 40 inches. The key point is, both men have the same BMI.

Does this mean that both men have the same risk of developing insulin resistance and metabolic syndrome? No.

The man who has poor body composition (low level of lean body mass, high level of fat mass) and carries his body fat around his waist (central obesity) is at risk of developing insulin resistance and metabolic syndrome. The physically fit man with a low amount of body fat and a slim waist is at very, very low risk of insulin resistance and metabolic syndrome.

Unfortunately, many individuals pay more attention to body weight than to body composition. Scientists, however, know better.

The easiest surrogate assessment of body composition is central obesity, and the easiest way to determine central obesity is to measure waist circumference — if you have a big waist, your risk of metabolic disease is increased.

Step 2: Maintain Good Body Composition.

How do you obtain and maintain good body composition? Maintaining lean body mass and decreasing body fat is easier than you think.

First, do not fall for the latest fad diet. Maintaining a stable body weight is not magic. Ignore any diet “guru” who promises “magical” weight loss, vilifies “forbidden foods,” and promotes excluding certain food “types” based on the latest round of misunderstood and misinterpreted science. Do not buy into it!

Instead, simply eat more whole foods and fewer processed foods. Prioritize eating high-quality foods like salmon, vegetables, wild rice, berries, and citrus fruits. De-emphasize eating foods that are highly processed or of low nutritional value, such as cakes, cookies, bagels, fried chicken, and American cheese. In fact, studies show that diets that emphasize whole foods, such as the Mediterranean diet, help maintain lean body mass while also improving metabolic markers like insulin, cholesterol, fibrinogen, and uric acid.7 Other studies of people eating Mediterranean-type diets show a strong reduction in cholesterol levels, increased psychological and physical well-being, and a trend towards weight loss even without trying to diet.8

A great-tasting, healthy diet is abundant in whole foods, much like the traditional diets of Africa, Asia, and the Mediterranean. This style of eating is rich in whole grains, whole fruits, and green vegetables, incorporates low to modest amounts of protein, and is high in “good fats” from sources such as sesame seeds, walnuts, almonds, and olives. Moderate amounts of high-fiber carbohydrates and “good fats” predominate in traditional diets of the Mediterranean, Asia, and Africa.

Randomized clinical trials have shown that this type of diet may be best for people at risk for metabolic disease. For example, a trial in patients with type II diabetes mellitus showed better blood sugar control and cholesterol levels in people consuming a diet comprising 40% carbohydrates, 45% fat, and 15% protein compared to those who consumed a diet consisting of 55% carbohydrates, 30% fat, and 15% protein.9

In other studies, a diet moderate in carbohydrates and relatively high in monounsaturated fat from olive oil and polyunsaturated fat from fish—such as the Mediterranean diet—actually decreased insulin resistance and inflammation.10 Furthermore, this diet is better than the step I National Cholesterol Education Program (NCEP) diet in preventing heart disease and stroke.11

Second, if you are not physically active, start moving your body! Simply walking at a brisk pace three to five days each week for at least 20 minutes will help. If and when you get more ambitious, you can engage in more demanding physical activities at a higher level of exertion. In addition, consider weight training to build more muscle mass and to stimulate your metabolism.

Step 3: Improve Metabolic Function with Nutritional Supplements.

Smart supplementation can have a significant impact on metabolic health. A number of nutritional supplements hold great promise for normalizing blood sugar and metabolic control.

Chromium. Chromium is a critically essential cofactor for glucose control. Chromium helps insulin shuttle blood sugar (glucose) into cells. In fact, without chromium, insulin cannot work properly.

Unfortunately, most Americans are deficient in this critical nutrient. Some experts believe that Americans ingest less than half the recom-mended daily amount of chromium.12 This may be partly due to the nation’s over-reliance on processed foods, which are generally rich in calories but poor in nutrients.

Another factor contributing to widespread chromium deficiency is food grown in soil containing a low content of minerals such as chromium. In fact, the 1992 Earth Summit report showed that North American soils have been depleted of 85% of their mineral content in the past 100 years—the highest rate of mineral depletion in the world.13 Thus, it should come as no surprise that the foods we consume are deficient in trace minerals such as chromium. Some scientists have postulated that rising rates of metabolic syndrome and diabetes in the US may result in part from declining levels of chromium in American soil and diets.

Many clinical studies of patients with and without metabolic disease have shown metabolic benefits—including improved blood sugar control, cholesterol, and insulin—with supplemental chromium doses from 200 to 1000 mcg daily.14-17

Recently, a bioavailable and biologically safe form of chromium called chromium 454™ has attracted the attention of nutritional scientists seeking ways to promote metabolic health. Derived from plant and biological extracts, this distinct form of chromium is water soluble, allowing for outstanding absorption. Insulin-deficient diabetic rats that received chromium 454™ for three weeks demonstrated an impressive 38% reduction in blood glucose levels. These findings led scientists to suggest that chromium may provide metabolic support for individuals seeking to optimize their blood glucose levels.18

DHEA. In both middle-aged and older men and women, suboptimal hormone profiles are not unusual. Dehydroepiandrosterone (DHEA) is a critical hormone that is involved in many metabolic processes, both directly and indirectly (through its conversion to testosterone and estrogen).

Low levels of DHEA are associated with an increased risk of developing metabolic syndrome. For example, a cross-sectional study of 400 men, aged 40-80, showed that the lower the DHEA level, the greater the risk of insulin resistance and metabolic syndrome.19

DHEA dosing should be individualized based on blood testing. A simple blood test known as DHEA-sulfate (DHEA-S) will provide important information about your DHEA levels. However, even relatively low doses can provide benefit. A study of elderly men and women showed that a daily dose of as little as 50 mg of DHEA for six months was associated with significant fat loss and improvements in insulin sensitivity.20

EPA/DHA. The long-chain omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) have a multitude of health benefits, including increased fat burning and improved glucose metabolism.21 In addition, EPA and DHA decrease the expression of genes involved in fat storage,22 down-regulate genes involved in inflammation,23 and lower levels of C-reactive protein, a marker of inflammation.24

Be careful, however, if you consume large amounts of fish, as you may be unwittingly ingesting large amounts of mercury, a kidney toxin that is found in high amounts in fish such as swordfish, shark, and even tuna.25,26 Supplementing with a high-quality omega-3 fatty acid product that has been tested and found to be free of contaminants and pollutants is a smart alternative to eating mercury-contaminated fish.

Bioflavonoids. Inflammation is an important factor in the development of insulin resistance and metabolic syndrome.27,28 Bioflavonoids like quercetin, resveratrol, and olive polyphenols have natural anti-inflammatory properties and may offer protection against metabolic syndrome.

Quercetin, a potent bioflavonoid found in vegetables, inhibits pro-inflammatory cytokines (proteins involved in immunity and inflammation).29 Resveratrol, found in the skin of red fruits like grapes, has been shown to inhibit the expression of genes involved in inflammation better than the potent prescription corticosteroid dexamethasone.30


Green tea is a super-nutrient. Life Extension members have long known about the anti-cancer benefits of green tea rich in epigallocatechin gallate (EGCG). Green tea also has valuable metabolic advantages.

Green tea promotes healthy blood sugar (glucose) metabolism in humans and obese, diabetic mice without increasing insulin levels.32 Life Extension has long warned about the dangers of excess insulin levels. Green tea rich in EGCG enhances insulin action instead of promoting insulin release.33 Furthermore, green tea and EGCG reduce fat cell creation and growth, as well as blood levels of triglycerides and cholesterol.34

As an added bonus, green tea protects against protein oxidation and glycation (the process by which tissues become damaged by high levels of circulating blood glucose).35

In addition to having potent anti-inflammatory effects,31 olive polyphenols have beneficial benefits on the cardiovascular system. Studies show that olive polyphenols dramatically increase the resistance of cholesterol to oxidation.36 This is very important, as oxidized cholesterol serves as a trigger for atherosclerosis (hardening of the arteries).37 Olive polyphenols also benefit the vascular endothelium, the lining of blood vessel walls. Hydroxytyrosol, a principal polyphenol in olives, reduces the “stickiness” of cells in the vascular endothelium.38 Cell “stickiness” may increase the tendency to form blood clots in the arteries.

Carotenoids and retinoids. Carotenoids (found in foods like carrots, squash, and tomatoes) and retinoids, which are beneficial to eye health, also play an important role in preventing metabolic disease.

Interestingly, experiments in early growth and development show that low vitamin A intake decreases insulin-producing cells,39 pointing to the importance of adequate vitamin A intake for development of the insulin-producing cells of the pancreas.

The National Health and Nutrition Examination Survey found that even after adjusting for confounding factors like age, sex, ethnicity, education, smoking status, and physical activity, people with metabolic syndrome had significantly lower concentrations of carotenoids and retinyl esters (a type of vitamin A).40

Evidence suggests that there may be a threshold for vitamin A consumption in terms of metabolic benefit. In one study, daily vitamin A intake of more than 10,000 IU significantly lowered blood sugar and insulin levels in healthy human volunteers, while daily intake of less than 8000 IU was associated with higher blood sugar levels.41

Water-soluble cinnamon extracts. Exciting data show that a special extract from cinnamon holds tremendous promise for normalizing blood sugar levels naturally.

A 2003 study of patients with type II diabetes examined the effects of cinnamon on blood sugar. Participants received one, three, or six grams per day of cinnamon or placebo. After 40 days, the three groups receiving cinnamon demonstrated significant reductions in blood sugar of up to 29%, in triglycerides of up to 30%, and in cholesterol of up to 26%.42

So, all you need to do to prevent metabolic disease is consume large amounts of cinnamon, right? Wrong!

Whole cinnamon contains volatile oils, which are well-known irritants that may trigger allergic reactions. Even more worrisome is that toxicology studies in mice show that consuming raw cinnamon rich in these oils can cause tumors, including squamous cell papillomas.43 Therefore, the best strategy is to avoid the danger of cinnamon’s volatile oils while still obtaining the remarkable benefits of cinnamon.

Fortunately, these oils are not responsible for cinnamon’s impressive effects in stabilizing blood sugar. Instead, cinnamon’s water-soluble polyphenol polymers are the key components responsible for its beneficial metabolic effects.44

The polyphenol type-A polymers from cinnamon up-regulate genes involved in blood sugar control.45 Other cinnamon polyphenol polymers such as methylhydroxychalcone have additional beneficial effects on blood sugar control.46 Recent studies consistently show the anti-diabetic effects of cin-namon extracts in validated animal models of metabolic disease.47,48

Cinnamon extract not only supports healthy blood sugar levels, but also has excellent antioxidant properties. The natural water-soluble cinnamon extract inhibits oxidation even better than the powerful synthetic antioxidant butylated hydroxytoluene, or BHT.49

Coffee polyphenols. Who would have ever thought that a water-soluble extract of coffee acts to boost the key target hormone that multi-billion-dollar pharmaceutical companies are targeting as the next breakthrough treatment for meta-bolic disease?

A very large study (14,629 men and women) published in the Journal of the American Medical Association in 2004 showed that the greater your coffee consumption, the lower your risk of metabolic disease, including type II diabetes mellitus.50 Another very large study that followed 41,934 men showed a similarly powerful association between increased coffee intake and decreased risk of type II diabetes, even after adjusting for age, body mass index, and other risk factors.53


A traditional folk remedy from Southeast Asia, banaba leaf extract may offer powerful support for people seeking to maintain healthy blood sugar levels. Banaba (Lagerstroemia speciosa L.) contains an active ingredient called corosolic acid. Laboratory, animal, and human studies show that corosolic acid effectively helps to support optimal glucose metabolism.51

Adults with diabetes or impaired glucose metabolism who received corosolic acid prior to an oral glucose tolerance test demonstrated significantly lower post-challenge glucose levels than people who did not take corosolic acid.51

A randomized clinical trial showed that banaba leaf extract rich in corosolic acid benefited adults with type II diabetes. When the diabetic individuals took a standardized corosolic acid supplement each day for two weeks, their blood glucose levels decreased by 20-30%.52

These findings suggest that banaba leaf extract standardized for corosolic acid content may benefit the millions of Americans who seek support for optimal blood sugar levels.

Before you decide to drink a pot of coffee a day or open your own Starbucks, be advised that drinking large amounts of coffee is not the best strategy for preventing meta-bolic disease.

Coffee can cause insomnia and may induce high blood pressure in some people, largely due to its caffeine content. Morever, results of the 2004 ATTICA study showed that coffee consumption dramatically increases markers of inflammation like C-reactive protein, interleukin-6, and tumor necrosis factor-alpha.54

A smart strategy is to identify and isolate the components of coffee that are responsible for its beneficial effects on metabolism, including blood sugar control. Scientists have found that water extracts of roasted coffee residues, including the primary coffee polyphenols caffeic acid and chlorogenic acid, are key components responsible for coffee’s beneficial metabolic effects.

Preclinical studies show that chlorogenic acid improves blood sugar control and decreases cholesterol and triglycerides.55

In human studies, chlorogenic acid, a major polyphenol in water extracts of coffee, has improved the release of hormones critical to blood sugar control. For example, in healthy human volunteers, consuming coffee polyphenols like chlorogenic acid dramatically increased glucagon-like peptide 1 (GLP-1) secretion.56 This finding is remarkable because several GLP-1-related pharmaceutical agents are targeting this hormone as a treatment for metabolic disease, including the recently FDA-approved GLP-1 analog BYETTA™ (exenatide). Chlorogenic acid acts to increase GLP-1.57

Coffee extracts offer other benefits as well. Water-soluble coffee polyphenols like chlorogenic acid scavenge free radicals and provide powerful protection against lipid peroxidation and oxidative damage by proteins.58


  • DHEA: 10-50 mg daily to start (men); 10-30 mg daily to start (women). Assess the effects of supplementation via repeat blood tests.
  • EPA: 1400 mg daily; DHA: 1,000 mg daily. Take with meals. Double these doses to combat high triglyceride levels.
  • Mixed bioflavonoids: 1400 mg twice daily.
  • Vitamin A: 4000 IU daily; mixed carotenoids (for example, lutein: 15-20 mg daily; lycopene: 3-30 mg daily; zeaxanthin: 3-10 mg daily)
  • Water-soluble cinnamon extract: 125 mg three times daily, 30 minutes before meals.
  • Chromium: 400-800 mcg daily.


With so much focus on cholesterol, little attention has been paid to the critical role of insulin resistance in the development of cardiovascular disease. Insulin resistance is the root cause of metabolic syndrome, a serious risk factor for heart disease and stroke that has received little attention until recently.

Identifying your risk for metabolic syndrome involves only a series of very simple tests. If you are found to be at risk, decreasing your body fat—particularly around your waist—is critically important. Avoid fad diets, eat a whole-food diet like those consumed by Mediterranean cultures, and get some physical exercise—your body will thank you for it!

Nutritional supplements can help improve blood sugar control and metabolic health naturally, without danger or stress to your body. Particularly compelling are polyphenol-rich, water-soluble extracts of cinnamon and coffee, along with green tea extract, chromium, and banaba leaf-derived corosolic acid. Documented evidence demonstrates the ability of these agents to help normalize blood sugar levels.

Avoiding the perils of metabolic syndrome is simple. First, get tested to see whether you are at risk. If laboratory testing and a physical examination reveal that you are at risk, immediately take the necessary steps—including exercise, a healthy diet, and targeted nutritional strategies—to prevent the dire cardiovascular consequences of insulin resistance and metabolic syndrome.


Drug companies are keenly interested in developing new drug treatments for people with metabolic syndrome. Unfortunately, due to the overwhelming drive by multibillion-dollar pharmaceutical companies to continually make profits, one of the very best drugs to help increase insulin sensitivity and improve blood sugar control (without promoting weight gain) is rarely mentioned. This drug, metformin, is currently off patent and very cost-effective.

Metformin, which belongs to a class of drugs called biguanides, works in several different ways to improve insulin’s ability to work at the cellular level in tissues such as muscle and the liver. Metformin is not associated with weight gain—a major advantage over all other drugs used to treat diabetes. Of additional interest is that gene-chip research funded by Life Extension showed that metformin influences gene expression in ways similar to those of caloric restriction. This suggests that metformin may have potential anti-aging benefits in addition to its documented effects on blood sugar control.

Other currently available drugs that may be useful in treating metabolic syndrome include the thiazolidinediones, a class of drugs approved for the treatment of diabetes.

Thiazolidinediones include GlaxoSmithKline’s rosiglitazone (Avandia®) and Takeda/Eli Lilly’s pioglitazone (Actos®). Thiazolidinediones work by targeting PPARs (peroxisome proliferator-activated receptors), which are attractive drug targets for treating metabolic disease.

PPARs help regulate the expression of genes involved in the storage and use of dietary fats. Two subtypes, PPAR alpha and PPAR gamma, have insulin-sensitizing effects.

Among the new drugs in development for metabolic syndrome are AstraZeneca’s tesaglitazar, and Bristol-Myers Squibb’s muraglitazar.

Individuals with kidney disease should not use metformin. Rosiglitazone (Avandia®) and pioglitazone (Actos®) should not be used by people with a history of congestive heart failure or liver disease. Please consult your doctor before using any pharmaceutical drug to treat metabolic syndrome.
