Sleep takes all that hard work you’re doing in the kitchen and the gym, and fast tracks those results. A good night’s sleep helps your body recover from activity and also regulates hormones responsible for hunger cues. “Sleep is essential [for fat loss and overall health]. It’s recommended that adults get 7-8 hours per night. There are a lot of studies on [sleep and fat loss], showing that good sleep can help us eat better and help us to lose weight,” says White. The two specific hormones sleep has an influence over are leptin and ghrelin. Leptin works to keep your energy steady and appetite low. Alternatively, ghrelin increases feelings of hunger. When you fail to get adequate sleep, ghrelin is increased and leptin is decreased, which messes with your hunger signals and can cause you to eat more. By getting your 7-8 hours a night you’ll avoid any wacky cravings and emotional eating, which will make your fat-loss goals that much easier to achieve.
Which means, sadly, the more glasses of rose and chocolate-coated pretzels you eat, the longer it will take to reach your flatter belly goals. “When you digest large amounts of calories, your body allocates some of these to functional systems which work to keep you alive (think the brain, muscles and organs),” says Belalij. “It also uses it to fill up energy stores. Any excess is then stored in fat cells around the body – typically being those of the belly.”
