Many studies have found that people who are sleep-deprived report having an increased appetite. This is likely caused by the impact of sleep on two important hunger hormones, ghrelin and leptin.

Poor Sleep Can Increase Your Appetite

Ghrelin is a hormone released in the stomach that signals hunger in the brain. Levels are high before you eat, which is when the stomach is empty, and low after you eat.

Leptin is a hormone released from fat cells. It suppresses hunger and signals fullness in the brain.

When you do not get adequate sleep, the body makes more ghrelin and less leptin, leaving you hungry and increasing your appetite.

A study of over 1,000 people found that those who slept for short durations had 14.9% higher ghrelin levels and 15.5% lower leptin levels than those who got adequate sleep.

The short sleepers also had higher BMIs.

In addition, the hormone cortisol is higher when you do not get adequate sleep. Cortisol is a stress hormone that may also increase appetite.

Brief Summary:

Poor sleep can increase appetite, likely due to its effect on hormones that signal hunger and fullness.
