Yo-Yo Dieting
You probably assumed that yo-yo dieting isn’t great for your mental health, but it’s also bad for your heart health on top of it. Research presented at the American Heart Association (AHA) convention in 2019 revealed that women who reported at least one incidence of yo-yo dieting—in which they lost 10 pounds and regained it within a year—were 65 percent less likely to have an overall “optimal” rating on AHA’s Life’s Simple 7, which measures how under control one’s heart disease risk factors are.
