Will I Gain Weight If I Stop Eating?

There's a persistent theory about something called starvation mode, and the thought that if you stop eating, you'll actually gain weight instead of losing it. This comes up when you talk about intermittent fasting (IF), metabolism, and on-and-off dieting, and it can (and has) cause much confusion. If you're trying IF, trying to curb overeating habits, or just shifting your overall calorie consumption, especially for weight loss, it's worrying to hear that it could actually work against you. POPSUGAR talked to three experts to see what's really going on.
