Another study linking diet and sleep. This article describes research with normal weight, healthy men after one night of sleep deprivation. Researchers gave the men about $50.00 to buy groceries the morning after a normal night's sleep or a night of sleep deprivation. After the night of sleep deprivation, the men bought more food and food that had more calories. The sleep-deprived men also had elevated levels of ghrelin, a hormone involved in appetite, but this did not correlate with food purchase behavior.
The take home message was to not go grocery shopping after a night of sleep loss. I wonder if the effect would taper for the many Americans who have chronic, partial sleep deprivation?
