Steer Clear of the HCG Diet


Based on the work of a British physician in the 1950s, the HCG diet combines daily injections or liquid supplements of a hormone, human chorionic gonadotropin (HCG), with severe calorie restriction (500 a day). Proponents claim HCG produces fast and hunger-free weight loss and that it targets “problem” fat areas (the belly, hips and thighs), while preserving, or even increasing, muscle mass. It has been called a miracle—and a scam.
HCG is produced in small amounts in both men and women; more is produced during pregnancy. Doctors use it, legitimately, to treat infertility. More dubiously, however, some doctors prescribe it as a weight-loss aid. A number of websites now sell nonprescription “homeopathic” formulas that you take as drops, pellets or sprays—a more “convenient” option.
What you need to know
• There’s no good evidence that the diet works. Controlled studies have shown that people lose the same amount of weight when they restrict calories to 500 a day, whether they get injections of HCG or a placebo. That is, the weight loss is due to the calorie deprivation (who wouldn’t lose weight eating so few calories?), not the injected hormone. An analysis of 24 studies in the British Journal of Clinical Pharmacology in 1995 concluded that HCG “does not bring about weight loss or fat redistribution, nor does it reduce hunger or induce a feeling of well-being.” There hasn’t been much research since then.
• Over-the-counter HCG products have not been tested in studies, and there’s no reason to think they would work, either. The Food and Drug Administration (FDA) considers them unapproved—and thus illegal—drugs. Be wary also of websites selling injectable HCG.
• In the large doses given for infertility, HCG can cause breast tenderness, depression, shortness of breath, blood clots and other side effects. Though smaller amounts are used for weight loss, hormones have physiological effects—good or bad—at any dose. You should not take hormones even at low doses unless they are clearly necessary.
• The calorie level of the diet is dangerously low—near starvation levels—and can’t be sustained. It can cause weakness, fatigue, protein malnutrition and loss of bone minerals over time.
• The “HCG protocol”—consultation, injections (that you do yourself), blood tests and follow-up—can run hundreds of dollars a month. Web-based diet programs sell “homeopathic” HCG products for $60 or more a month.
• Like other fad diets, it’s not a long-term solution. Once you stop, the weight will return unless you make lasting diet and lifestyle changes.
Bottom Line: The HCG diet is “complete quackery,” says John Swartzberg, M.D., chair of the editorial board of Berkeley Wellness. Save your money.

Adopting a Vegetarian Diet

Adopting a vegetarian diet has become a popular choice for individuals looking to improve their health, particularly as heart disease and obesity rates continue to rise in many parts of the world. Vegetarians tend to have lower cholesterol levels and consume fewer trans fats than those who consume meat and dairy products. However, to maintain good health, vegetarians must ensure they obtain the right amount of nutrients from their vegan diets. By taking care to plan their diets carefully, vegetarians can enjoy a satisfying and tasty way of life. While there is no established vegan diet, it is widely agreed that with so many vegetarian diets to choose from, the choice is ultimately up to the individual. However, vegetarians must be cautious not to make their diets too restrictive as this can lead to difficulties in meeting the body's daily nutritional requirements. Commonly deficient nutrients among vegetarians include protein, iron, vitamin B12, vitamin D, calcium, and zinc. Soy pr...

Is White Wine Good For Your Heart?

Is white wine as "heart healthy" as red wine? Here’s what you should know about the heart health benefits of white wine. The answer is  probably  -- though researchers continue to debate the question. Some studies have indicated that red wine is modestly better for the heart than white wine (or beer or spirits) because it contains resveratrol -- a polyphenol (plant chemical) associated with cardiovascular benefits, including reduced risk of heart attack. Resveratrol is found in the seeds and skin of grapes, which are crushed together with the pulp to make red wine. White wines, on the other hand, are made with just pulp and therefore contain very little resveratrol. But recent studies have shown that the pulp does contain other polyphenols that may be heart healthy. Moreover, although red and white wines differ in polyphenol composition, both contain similar amounts of alcohol -- which is known to increase level s of HDL ("good") cholesterol and prevent bl...

Does Your Family Encourage Your Obesity?

Anyone who has ever tried to lose weight knows how difficult it can be. Unfortunately, many times those who should support us the most, our family, make it even harder to succeed. No matter what the reason, family members can sabotage our weight loss goals without us even realizing it. They may sound like loving comments, but if you hear these lines, be aware and walk away. I Love You Just the Way You Are This line is killer. It implies that we don't love ourselves the way we are and that we are losing weight just to make them love us more. With health and self-esteem issues on the line, other people's opinions may be far down the list of reasons why you want to lose weight. The unspoken question behind this statement is, "Will you love me just as much if I change and get healthier?" You should have a frank discussion about this topic with your loved ones as soon as you begin your weight loss journey. You Deserve This One Treat This usually happens on holidays, ...
