Insomnia
Without your recommended seven to eight hours of sleep every night, your body will find it harder to regulate the hormones that control your hunger levels when you wake up. The hunger hormone ghrelin will spike, making you reach for food, even when your body doesn’t need the calories. “Every day, you’re getting up and have metabolic demands,” says Dr. Levine. “It’s a form of stress when you deprive yourself of sleep and cause hormone dysregulation.”
