Yo-yo dieting or yo-yo effect, also known as weight cycling, is a term coined by Kelly D. Brownell at Yale University, in reference to the cyclical loss and gain of weight, resembling the up-down motion of a yo-yo. In this process, the dieter is initially successful in the pursuit of weight loss but is unsuccessful in maintaining the loss long-term and begins to gain the weight back. The dieter then seeks to lose the regained weight, and the cycle begins again.
Let’s take a look at this article by Ana Sandoiu
New research reveals worrying associations between yo-yo dieting and seven well-established markers of cardiovascular health.
New research looks into how yo-yo dieting may affect a woman's cardiovascular health.
As if losing weight wasn't hard enough, up to 80 percent of people who manage to lose more than 10 percent of their body weight end up regaining the weight within a year.
Losing weight for a short period and then regaining it bears the name of yo-yo dieting, which some people refer to as "weight cycling."
Previous research has pointed out the potentially damaging effects of these repeated cycles of weight loss and weight gain
Some studies have suggested that yo-yo dieting raises the risk of mortality from any cause, while others have pointed to an increased risk of death from heart disease in particular.
Another study suggested that yo-yo dieting can lead to a cardiometabolic "roller coaster" in which cardiovascular health remarkably improves with just a few weeks of healthful dieting, but the negative cardiovascular effects are immediate once the individual abandons the diet.
Now, scientists have turned their attention to the cardiovascular effects of yo-yo dieting in women.
Dr. Brooke Aggarwal, who is an assistant professor of medical sciences at Columbia University Vagelos College of Physicians and Surgeons in New York, led a team examining the effects of weight cycling on seven heart disease risk factors.
Dr. Aggarwal and her colleagues presented their findings at the American Heart Association's (AHA) Epidemiology and Prevention | Lifestyle and Cardiometabolic Health 2019 Scientific Sessions, which took place in Houston, TX.
