Now you can stop feeling guilty when you go to bed early and skip your daily workout because proper sleeping habits can help control your body weight. When you sleep, the hormones that regulate your appetite are placed back in control, possibly ridding your thoughts of those nasty cravings. When you deprive your body of sleep, your body naturally craves sugar and carbohydrates as a defense mechanism to jolt you awake. For those of you who can’t seem to shed those last five pounds, try hitting the hay an hour early.
