Lack of ZZZs May Fuel Appetite

From Health­Day News

Get­ting too lit­tle sleep can make you hun­grier than nor­mal and may lead to weight gain, a small study suggests.

The team at Upp­sala Uni­ver­sity in Swe­den used func­tional MRI to observe the brains of 12 nor­mal weight males while they looked at images of food. This was done on two occa­sions — after a night of nor­mal sleep and after a night with­out sleep.

The results showed that a spe­cific brain region that plays a role in appetite shows more acti­va­tion in response to food images after a night with­out sleep than after a night of nor­mal sleep.

This sug­gests that poor sleep habits can affect a person’s risk of becom­ing over­weight in the long run, accord­ing to the study pub­lished online Jan. 18 in the Jour­nal of Clin­i­cal Endocrinol­ogy and Metabolism.

After a night of total sleep loss, these males showed a high level of acti­va­tion in an area of the brain that is involved in a desire to eat,” researcher Chris­t­ian Bene­dict said in a uni­ver­sity news release.

Bear­ing in mind that insuf­fi­cient sleep is a grow­ing prob­lem in mod­ern soci­ety, our results may explain why poor sleep habits can affect people’s risk to gain weight in the long run. It may there­fore be impor­tant to sleep about eight hours every night to main­tain a sta­ble and healthy body weight,” Bene­dict added.
