interesting. energy use during sleep seems to be a sort of arbitrage opportunity, since we spend so much time sleeping, and are unconscious so we can't get hungry. dieters used energy "more efficiently" while asleep than did the control group. less energy wasted (?), slower metabolism. potentially a positive feedback loop -- waking up with more stored energy left? perhaps one of the things that causes people to adjust to dietary changes over time.
