Sleep deprivation and food purchases

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?
