Chronic lack of sleep may contribute to obesity.<\/strong><\/em><\/span><\/p>\n

\"AmericanSan Diego, CA<\/strong> – If you don\u2019t get enough sleep, you may also eat too much \u2014 and thus be more likely to become obese.<\/p>\n

That is the findings of researchers who presented their study at the American Heart Association\u2019s Epidemiology and Prevention\/Nutrition, Physical Activity and Metabolism 2012 Scientific Sessions.\u201cWe tested whether lack of sleep altered the levels of the hormones leptin and ghrelin, increased the amount of food people ate, and affected energy burned through activity,\u201d said Virend Somers, M.D., Ph.D., study author and professor of medicine and cardiovascular disease at the Mayo Clinic, Rochester, MN. Leptin and ghrelin are associated with appetite.<\/p>\n

The researchers 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.<\/p>\n

Participants ate as much as they wanted during the study.<\/p>\n

Researchers found:<\/h3>\n
    \n
  • 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.<\/li>\n
  • The amount of energy used for activity didn\u2019t significantly change between groups, suggesting that those who slept less didn\u2019t burn additional calories.<\/li>\n
  • Lack of sleep was associated with increased leptin levels and decreasing ghrelin \u2014 changes that were more likely a consequence, rather than a cause, of over-eating.<\/li>\n<\/ul>\n

    \u201cSleep deprivation is a growing problem, with 28 percent of adults now reporting that they get six or fewer hours of sleep per night,\u201d said Andrew D. Calvin, M.D., M.P.H., co-investigator, cardiology fellow and assistant professor of medicine at the Mayo Clinic.<\/p>\n

    The researchers noted that while this study suggests sleep deprivation may be an important part and one preventable cause of weight gain and obesity, it was a small study conducted in a hospital\u2019s clinical research unit.<\/p>\n

    \u201cLarger studies of people in their home environments would help confirm our findings,\u201d Calvin said.<\/p>\n
