VitaminsAll Fat Loss Supplements Are Not Created Equal

By Anthony Colpo

Many people trying to lose weight try supplements to help burn fat and calories. And there are some legitimate, scientifically proven products out there that do just that. But all supplements are not created equal. Indeed, many weight loss supplement manufacturers will hate me for saying this, but it has to be said: Most of their products are worthless junk.

And even when their products do produce fat loss, the effect is typically so small that most people simply wouldn't notice any difference. Nor would most folks part with their hard-earned cash if they truly knew the tiny results they could expect.

To illustrate my point, let's take a quick look at three supplements currently being hyped for their alleged fat-burning properties.

CLA. A recent and widely publicized paper published in the American Journal of Clinical Nutrition concluded that conjugated linoleic acid (CLA), "does have a beneficial effect on human body composition." Sounds great, until you look closely at the results. After averaging the results from various CLA trials, the authors concluded that CLA resulted in an average reduction in fat mass of 90 grams a week. At that snail-like pace, it will take you three months to shed a kilo (2.2 pounds)!

The longest-running double-blind trial compared the effects of two different CLA supplements with a placebo. After 12 months, the average body fat changes in the CLA groups were -1.7 and -2.4 kilograms, compared to +0.2 kilograms in the placebo group. For a trial that lasted a full year, these results are miniscule. Most people sticking to an intelligently structured diet and exercise program can easily lose this amount of fat in less than two weeks.

If you think the piddling fat loss effects of CLA are worth parting with hundreds of dollars, then go for it. If not, leave the CLA supplements on the shelf and get your intake of this fatty acid the way nature intended -- from animal fats. Fat from grass-fed animals, by the way, has a higher CLA content than that from grain-fed animals.

Green tea. Green tea has received a lot of press over the last decade. Deservedly so. An increasing volume of research suggests that this antioxidant-packed beverage has a whole host of important health benefits, including protection against cancer.

But don't let anyone convince you that drinking tea is the answer to your fat loss dreams.

Consider a study published in the American Journal of Clinical Nutrition. It reported increased fat loss in men taking a high-potency tea extract. Those who bothered to read the study for themselves quickly realized the results were little to be excited about.

For 12 weeks a group of Japanese men consumed, in double-blind fashion, one bottle daily of a "high-strength" oolong tea mixture or a bottle of low-strength oolong tea. After 12 weeks, the men drinking the high-potency oolong tea shed 1.4 kg of fat, compared to 700 g in the control group. Waist circumference decreased 3.4 cm in the treatment group and 1.1 cm in the control group. It goes without saying, but to lose an extra 700 grams of fat over three months is hardly an earth-shattering result. Folks, we're not exactly talking a dud-to-stud transformation here.

It should also be mentioned this study was conducted by the same company that produced and marketed the tea extract. Other trials, conducted by Dutch researchers, have failed to confirm a fat loss effect from green tea.

Green tea is a pleasant and potentially healthful beverage. Just don't expect it to help you lose a whole lot of weight. Current clinical evidence suggests the results will range from minimal to none.

Hoodia. Hoodia is being vigorously marketed as an appetite suppressant. I went looking for supportive data. I could only find research showing that rats injected or tube-fed with a glycoside extracted from Hoodia reduced their caloric intake and lost weight. What this means for humans taking oral Hoodia supplements is anyone's guess; I couldn't find any studies examining its use in real live humans. In other words, all the Hoodia hype is predicated entirely on rodent research.

Readers should be very careful when extrapolating the results of animal research onto humans. Calcium and DHEA, for example, produce significant weight loss in rodents but have no such effect in healthy Homo sapiens.

When presented with wild fat loss claims from marketers and media outlets, you should always ask the following question:

"Where's the tightly controlled clinical research with real, live humans to support these claims?"

If these sources cannot provide you with any such research, then keep your money in your pocket. And treat any future claims these folks make with the utmost suspicion. If these sources can provide you with concrete research citations, seek them out and read them yourself. See whether the results truly justify the fuss being made. With online resources such as PubMed and nutritional/medical journal web sites, this is actually a lot easier than it sounds. The few minutes you take to do this could easily save you hundreds of dollars.

Alternative Eating:
Can a Low-Fat Diet Really Prevent Ovarian Cancer?

By Dr. Jonny Bowden

Girls with fruit and breadA new study has been touted as showing that a low-fat diet can reduce the risk for ovarian cancer. But the results are a lot iffier than you might believe.

The data came from the Women's Health Initiative Dietary Modification trial. Women who decreased the amount of dietary fat they ate were 40 percent less likely to develop ovarian cancer than women who followed "normal dietary patterns."

Here's the problem. When people follow what they think is "healthy" advice (like eat less fat), they are also more likely to do other things that can have health benefits (like stop smoking or eat more vegetables or exercise more). There's no way to account for how much the results are due to outside factors (what researchers call "confounding variables") like these.

In addition, a lot of research has shown that even when people are counseled to "eat less fat," eventually their fat intake starts to creep up. In this study the women were counseled to eat a diet containing 20 percent fat. By the end of the first year they were in fact up to 24 percent. By the end of the study, it was 29 percent.

Most important, the "fat reducing" women also increased their consumption of fruits and vegetables. There's absolutely no way to know whether their lower rate of ovarian cancer had to do with the reduced fat or the increased anti-cancer compounds, anti-inflammatories and anti-oxidants from the plant foods.

There's no doubt that obesity puts you at increased risk for a host of diseases, including some cancers. But fat on the body isn't the same as fat in the diet. We need to we get over the idea that "fat makes you fat." Insulin makes you fat, and carbohydrates, especially processed carbs, drive up insulin. The real culprits in our diet are sugar, processed carbs and junk food.

Healthy Aging:
Aspirin Can Boost Your Risk of Stroke

By Dr. Al Sears

Girls with fruit and breadYesterday, my neighbor asked me if it was a good idea to take aspirin to avoid heart attacks and stroke. I responded with a question of my own: "Would you take a painkiller if you weren't in pain?"

TV commercials make it sound logical, but taking aspirin regularly just causes a new set of problems. What I call "the law of unintended consequences."

A new study published in Lancet Neurology found that older people who are taking aspirin "preventively" may be seven times more likely to have a stroke. The same researchers estimated that if the misuse of drugs like aspirin continues to increase, it may soon overtake high blood pressure as the leading cause of stroke in those over 75.

Instead of taking aspirin, take steps to lower your homocysteine levels. Your cells dump this "toxic waste" product into your bloodstream as they burn energy. Too much homocysteine is a serious health risk. In fact, homocysteine levels are a better predictor of heart disease -- and stroke, by the way -- than anything else, including cholesterol.

You can lower your homocysteine levels simply by supplementing with B vitamin. No harsh drugs are necessary. Here's what I recommend:
• Vitamin B6 - 75 mg daily
• Vitamin B12 - 400 mcg daily
• Folic Acid - 800 mcg daily
