Opportunity: There are multiple ways. First, at night while watching tv and being bored, you're more likely to snack and take in extra calories. In addition, sleep triggers a hormone, leptin, that gives the feeling of satiety and decreased hunger. So getting less sleep makes you chronically more hungry.

A 16-year-old female asked:

Can lack of sleep cause stress and weight gain?

Dr. Joyce Pastore
Internal Medicine 29 years experience
Sleep: If the body does not get adequate sleep over time, the cortisol level will rise and weight gain can occur. This doesn't happen after one sleepless night - usually due to cumulative fatigue over days to weeks. Adults should get 7-8 hours of sleep per night, teens 9-10.
