Lose weight while you sleep. It sounds like
something you'd hear on a late night infomercial -- just around the time you
are reaching for that bag of cookies because, well, you can't sleep.
But as wild as the idea sounds, substantial medical evidence
suggests some fascinating links between sleep and weight. Researchers say that
how much you sleep and quite possibility the quality of your sleep may silently
orchestrate a symphony of hormonal activity tied to your appetite.
