When you're tired and frazzled, your body cranks up the production of cortisol, the stress hormone that can cause carb cravings, Frutchey says. Not getting enough sleep also boosts your levels of ghrelin, a hormone associated with hunger, while suppressing leptin, a hormone that signals fullness and satiety. People on a diet who slept only five and a half hours a night for two weeks lost 55 percent less fat and were hungrier than those who slept eight and a half hours, according to a study in the Canadian Medical Association Journal.
Use it to lose it. Prioritize sleep, aiming for seven hours or more a night, which research shows helps lower stress. And make sure you're getting quality zzz's. If a snoring spouse or a fidgety cat wakes you up frequently throughout the night, you may end up getting the equivalent of just four hours of sleep, according to a study from Tel Aviv University. Keep pets out of the bedroom, and use a white-noise app to drown out snoring.
