Recent studies have suggested an association between lack of sleep (or sleep duration) and weight gain. Sleeping less than five hours — or more than nine hours — a night appears to increase the likelihood of weight gain.

Sleep deprivation affects the brain in a way that makes you want to eat more and not process food efficiently. It sparks a vicious cycle where you are left feeling tired, slowing your metabolism and playing tricks with your hormones.

In one study, recurrent sleep deprivation in men increased their preferences for high-calorie foods and their overall calorie intake. In another study, women who slept less than six hours a night or more than nine hours were more likely to gain 11 pounds (5 kilograms) compared with women who slept seven hours a night. Other studies have found similar patterns in children and adolescents.

But Why?

Snacks: Your body has no energy and thinks you’re hungry. Science says getting less sleep than needed makes the body produce higher peaks of endocannabinoid, a lipid in the bloodstream that’s responsible for making eating feel so much more enjoyable.

Less exercise: The more sleep-deprived you are, the more lethargic you feel, and the less you will exercise. Going back to a sedentary lifestyle will inevitably result in weight gain, especially if you’re eating more.

More carb eating: Tired people tend to reach for foods that are high on bad carbs. After all, you are just looking for something to feel better.

Bottom Line

Sleep duration affects hormones regulating hunger — ghrelin and leptin — and stimulates the appetite. Another contributing factor is that lack of sleep leads to fatigue and results in less physical activity.
