This is a pretty extensive amount of research on the subject, if anyone's thought about trying it:
I've got a friend that's a coach who said "90% of the top athletes I have talked to that are concerned about leanness practice intermittent fasting". He doesn't at this point subscribe to it, but is currently experimenting on himself to see the effects. So far he's not a fan of the release of stress hormones. The above article shows several successful examples, so I think it's worth a shot for anyone interested.
I'm on the fence just because last time I tried something like this I went 18 hours and then was scarfing fast food.
My buddy's doing 4 days to a week of 16 hour intermittent fasting. Seems reasonable.
