Men who stay awake all night tend to consume bigger portions of calorie-dense foods the next day, say researchers.
Researchers from Uppsala University in Sweden analysed the eating patterns of 16 normal-weight males under buffet-like conditions after they were deprived of sleep all night, following a night of a solid eight-hour rest.
AdvertisementRespondents were asked to select their portion sizes of seven meals and six snack items in both states.
Lead researcher Pleunie Hogenkamp said that after a night of total sleep loss, the sleep-deprived males chose greater portion sizes of the energy-dense foods.
He told the New York Daily News that males did so both before and after a breakfast, suggesting that sleep deprivation enhanced their food consumption regardless of satiety.
The study has been published online in the journal Psychoneuroendocrinology.
