Various studies suggest that people who sleep less tend to be overweight compared with people who sleep well. When a person has a sleep disorder, it affects the hormone that regulates the body's metabolism and appetite control, the leptin hormone.
Leptin hormone serves to produce hunger and help regulate one's appetite. Well when one's leptin hormone is too high, then the body will experience a disruption to the perception of satiety. Their bodies will continue to feel hungry despite having eaten a lot. As a result, you become often snacking, especially at night before bed.
