THE MYTH: Yo-yo dieting wrecks your metabolism
It's become common wisdom that depriving yourself of food — a.k.a. dieting — puts you into "starvation mode," in which you burn fewer calories because your body needs to hold on to what little nutrition it's getting; over time, the theory goes, your metabolism slows down for good. But "while extreme low-calorie diets do temporarily lower your metabolism, the effects don't last," Snyderman says. Researchers in Canada compared the resting metabolic rates of women who'd yo-yo dieted for an average of 18 years with what their metabolism should be for their height, weight, and age — and found no difference in 92 percent of the subjects. "Yo-yo diets don't hurt you, but they do frustrate you because they mean you haven't found the right way to keep the weight off," says Snyderman.
