My doctor’s been on my back to lose a few pounds. That’s good, because it’s kept me from gaining any more. Otherwise, it hasn’t been very effective. But now I think I’ve figured out the secret:

After two weeks, the people who slept more lost more fat than the group who slept less. More than half of the weight loss during the 8.5 hours of sleep was fat versus only one quarter of the weight loss during the 5.5 hours of sleep. People literally burned fat while they slept.

I found this on the internet so it must be true. See the whole piece at Psychology Today.
