HCG Diet: Starving on Pregnancy Hormones?

ABC News(NEW YORK) -- 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 consumer 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.´╗┐

500-Calorie Hormone Diet 'Could Be Dangerous,' Critics Say 

Jeffrey Hamilton/Thinkstock(NEW YORK) -- A diet involving hormone injections that has been around for decades is gaining new traction after it was featured on a national talk show.

Dr. Oz featured the 500-calorie diet that relies on injections of the pregnancy hormone HCG on his show. Some critics of the diet are concerned because people are particularly responsive to an issue when they see a doctor on television speaking about it.

The problem, says dietitian Carla Wolper at Columbia University, is that the diet doesn't work and could be dangerous. Professionals that work with people dealing with obesity would never consider using anything like that, she added.

Five hundred calories a day is near starvation, and HCG injections, which Wolper calls an expensive scam, preys on vulnerable people.

The FDA, having approved three HCG products currently on the market, told ABC News in a statement that since the 1970s the "FDA has required labeling of HCG to state that HCG has not been demonstrated to be effective adjunctive therapy in the treatment of obesity. Numerous clinical trials have shown HCG to be ineffectual in producing weight loss."

The FDA also listed the potential health risks associated with HCG use including blood clots, depression, swelling, and the potentially life-threatening condition known as Ovarian hyperstimulation, a syndrome of sudden ovarian enlargement.
