Yo-Yo Dieting Linked With Dying Early, Study Suggests

There is no doubt that losing a few pounds if you are overweight or obese is a boon to your health. Doing so may help reduce your risk of developing type 2 diabetes, heart disease, and other chronic health conditions, according to the Centers for Disease Control and Prevention (CDC). But there is new evidence to support the notion that frequent re-weighting – a phenomenon called weight cycling or “yo-yo dieting” – is associated with a shorter lifespan.

Says one of the study’s authors, Tae Jong Oh, assistant professor in the department of endocrinology and metabolism in the department of internal medicine at Bundang Hospital at Seoul National University in South Korea.

Oh and his team analyzed health information for 3,678 men and women, ages 40 to 96, from the Korean Genome and Epidemiology Study. The researchers measured the participants’ weight and body mass index (BMI) twice a year, and considered the overweight to be a BMI of 25, which corresponds to The National Heart, Lung, and Blood Institute (NHLBI) definition of overweight in the United States.
