(KWTX) A new medical study finds that getting a few extra hours of sleep on the weekend can help slim your waistline.
South Korean researchers surveyed more than 2,000 people between the ages of 19 and 82.
All participants got an average of seven hours of sleep each night.
The participants who slept an extra two hours on the weekend actually had a lower body mass index than the participants that woke up on the weekends after just seven hours of sleep.
Dr. Chris Matlock, the medical director of the Providence Sleep Center in Waco, said unhealthy eating habits can develop with lack of sleep.
"Hormones that control our desire to eat or cravings to eat and get out of whack when you don't sleep, you tend to be hungry and crave foods that are not healthy for you." Matlock said.
Matlock also warns that sleep shortage is linked to increased risks of heart disease, high blood pressure, Type 2 diabetes, depression, and anxiety.
