Repeatedly losing and gaining extra pounds — yo-yo dieting, also called weight cycling — is linked to a number of negative health effects and a higher risk of death, according to a study published in the Journal of Clinical Endocrinology & Metabolism.

The 16-year study was conducted by researchers at Seoul National University College of Medicine and Bundang Hospital in Seongnam, Korea, who analyzed data on 3,678 men and women involved in the Korean Genome and Epidemiology Study. Interestingly, they found that in people with obesity, weight cycling was associated with a lower risk for developing type 2 diabetes. In these study participants, the health benefits of weight loss outweighed the adverse effects of yo-yo dieting.

In a scientific statement on the causes of obesity, the Endocrine Society indicates that about 80 percent of people who lose weight will eventually gain it back, because once you lose weight, your body reduces the amount of energy it expends and you feel hungrier. It’s this combination that typically leads to weight gain.
