Prevention's revolutionary Belly Melt Diet explains the science behind why getting a good night's sleep will help you lose while you snooze and how eating the right foods at the right times can satisfy your body's need for fuel and taste. What's more: Certain flat belly foods can actually help you sleep better and help you lose weight on their own. Research shows that our bodies' inner eat-and-sleep clocks have been thrown completely out of whack, thanks to cues we send it all day with the wrong foods—and too much artificial light at night. The result: You're caught in a "fat cycle": a constant flow of hunger hormones that makes your cravings all but impossible to resist. But if you tune into your body's natural eat and sleep schedules, you can actually—finally—say good-bye to your belly. Sounds good, right?
