hCG Diet just a rerun from the 1970s



With one-third of Americans obese and many more overweight, the nation is desperate for a weight-loss miracle. But the return of the hCG diet -- a fad popular in the 1970s that combines daily injections of "human chorionic gonadotropin" and extreme
caloric restriction -- has some weight-loss experts worried.

"We're so desperate to have good solutions for weight control that a lot of people with good common sense literally suspend it when it they confront weight-loss
claims," Dr. David Katz, director of the Yale University Prevention Research Center, said. "This diet is appalling. It takes irresponsible diets to new heights."

HCG is a hormone first produced by the developing embryo and then the placenta during pregnancy to help nourish the womb. Because calories are re-routed from mother to fetus during pregnancy, hCG diet promoters say, injecting the hormone will help curb appetite and allow dieters to get through a day on the energy equivalent of a turkey sandwich.

"A 500-calorie-a-day diet is just plain dangerous," Katz said. "When you restrict calories to that level, there's a real risk for not providing your body with
enough essential amino acids, so it scavenges itself. In some instances, it can cause the body to scavenge from critical places, like the heart."

The danger of very low-calorie diets has been well documented since their rise in popularity in the '70s. A 1981 study published in the American Journal of
Clinical Nutrition described 17 people, all of whom were initially obese and had significant and rapid weight loss, who died suddenly of ventricular arrhythmia after a median five months of dieting.

The lowest recommended caloric intake per day is 1,200 calories for women and 1,500 for men,according to the National Institutes of Health.Restricting calories beyond those limits should only be done under doctor supervision because of the health risks.

Some milder versions of the hCG diet allow dieters to consume 800 calories per day, and use hormone creams or drops instead of injections. "Frankly, it's all variations of the same nonsense," Katz said, calling hCG injections an expensive placebo effect.

  1. With the problem in health, particularly in obesity, I think there should be extensive campaigns to prevent obesity from health institutions and the government itself. We cannot really blame people for trying the HCG diet protocol and other weight loss methods that are being presented to them.
