I once saw a study on like a 20/20 show where they had test subjects who were allowed to eat certain things but were also forced to stay awake and get sleep deprived. Over the course of the days, the ppl ate worse and worse food. Apparently your body craves junk when your sleep deprived, probably for the quick sugar boost. Thus leading to obesity. I have to say that when I am tired I eat what is quick and cooking is not quick for the most part. Plus when your tired you don't want to exercise you want to sit and watch TV. SO this makes sense to me.
