I use to wrestle (highschool level, and trained with university level). I've heard of people who've dropped and gained 10-15% of their pre-cutting body mass like that. His claim is definately on the top end of things. The rehydration process is every bit as dangerous as the dehydration. You don't do it right, you just end up puking all over the place, which is no good when you're already dehydrated. I'm REALLY suspect one pound of muscle per day. If you want an idea of what that means... look at a 1 pound steak. You're adding that much to your body every day. I'll give him that there are probably genetic freaks of nature out there who can pull this stuff off (maybe he is one), but it's simply not a realistic goal.
