Racking up eight full hours of sleep isn’t going to result in losing the lbs. by itself, but itcan helpyour body from packing on the pounds. If you don’t get enough sleep, your body produces ghrelin, a hormone that boosts appetite. Your body also decreases the production of leptin, a hormone that tells you you’re full. Put ’em both together and that’s one dangerous combo for late-night snacking, my friend. Plus, when you don’t sleep enough you get more stressed and don’t have the energy to fight off junk food cravings. We’re exhausted just thinking about it.
