More research linking obesity to sleep deprivation

Here is an article that reviews a paper that summarizes research studies done on obesity and sleep deprivation over the past 15 years. The study authors concluded that partial sleep deprivation, defined as sleeping less than 6 hours per night can contribute to weight gain. It could be that sleep loss affect certain hormones that can regulate appetite. I'm still not convinced that if Americans slept longer, the pounds would drop off - that's too easy. To me, diet is so much more important than sleep quantity for controlling obesity.
