Report: Yo-yo dieting not that harmful

Yo-yo dieting _ repeatedly losing and gaining weight _ does not appear to carry significant health risks, researchers reported Wednesday.

Previous studies have indicated that yo-yo dieting may disrupt the body's metabolism, increase body fat and lead to heart problems and other health risks.

But in reviewing nearly 30 years of medical data on the subject, including studies on animals and humans, the National Task Force on the Prevention and Treatment of Obesity determined that health risks associated with obesity are far more conclusive.

"There is no convincing evidence that weight cycling in humans has adverse effects on body composition, energy expenditure, risk factors for cardiovascular disease or the effectiveness of future efforts at weight loss," the researchers wrote in Wednesday's Journal of the American Medical Association.

Health risks associated with obesity include heart disease, high blood pressure, diabetes and some types of cancer.
