Myth: Fasting amps up metabolism
Sure, you can lose weight by following any of the hundreds of fad diets out there but studies show the results will be short-lived. “Drastic diets don’t work and lead to weight gain, not loss, and can decrease your metabolism,” says Ellen Albertson, PhD, of South Burlington, Vermont. In addition, Albertson cautions that dieting increases stress and the hormone cortisol, which is associated with weight gain around the belly.
Myth: Metabolism slows down at night
Sounds logical. After all, your body isn’t doing much, right? Turns out there is no truth to the rumor, says Marc Leavey, MD, a primary care specialist in Lutherville, Maryland. “It turns out that the way your body handles the food and the calories contained within that food has a lot to do with what you’re eating, your body’s own unique physiology, and your level of activity,” says Dr. Leavey. Still, Leavey says chowing down on fatty food isn’t a good idea before bedtime. (Related: Not sure what to nosh on? Check out these healthy snack ideas.)
