Lack of sleep has been shown to have a direct link to hunger, overeating, and weight gain. Two hormones in your body regulate normal feelings of hunger and fullness. Ghrelin stimulates appetite, while leptin sends signals to the brain when you are full. However, when you’re short on sleep, your ghrelin levels go up, stimulating your appetite so you want more food than normal, and your leptin levels go down, meaning you don’t feel satisfied and want to keep eating. This can lead to overeating and, ultimately, weight gain.
To keep your diet on track, try to get about eight hours of quality sleep a night.
