If you don’t get enough sleep, you may also eat too much — and thus be more likely to become obese. That is the findings of researchers who presented their study at the American Heart Association’s Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2012 Scientific Sessions.
- The sleep deprived group, who slept one hour and 20 minutes less than the control group each day consumed an average 549 additional calories each day.
- The amount of energy used for activity didn’t significantly change between groups, suggesting that those who slept less didn’t burn additional calories.
- Lack of sleep was associated with increased leptin levels and decreasing ghrelin — changes that were more likely a consequence, rather than a cause, of over-eating.
