Scientists say that not getting a good night's rest could lead to obesity, the Daily Mail reported.
The researchers from the Mayo Clinic in Rochester, Minnesota, studied 17 normal, healthy young men and women for eight nights, with half of the participants sleeping normally and half sleeping only two-thirds their normal time.
The sleep deprived group, who slept one hour and 20 minutes less than the other group each day, consumed an average 549 additional calories daily. Meanwhile, the amount of energy used for activity didn't significantly change between groups, suggesting that those who slept less didn't burn additional calories and sleep deprivation may be a cause of weight gain and obesity.
