If you don’t get enough sleep, you also may end up eating too much, according to new research at Mayo Clinic.
Researchers studied 17 healthy young men and women between 18 years old and 40 years old for eight nights; half of the subjects slept for their usual time, and the other half slept two-thirds their normal time. All participants were allowed to eat as much as they wanted.
The research was presented March 14 at the American Heart Association’s Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2012 Scientific Sessions in San Diego.
– The group that slept one hour and 20 minutes less than the control group each day consumed an average 549 extra calories a day.
– The amount of energy used didn’t change significantly between the two groups. The researchers say this suggests that the group that slept less didn’t burn more calories.
– Less sleep was associated with increased levels of leptin and decreased levels of ghrelin — hormones associated with appetite. The authors say these changes were more likely a consequence, not a cause, of over-eating.
