Just visited his website, his main focus seems to be pushing his own supplements, which for me is a bit of a red flag. But I will grant you that a lot of what's behind obesity is mental/emotional/behavioral, so the behavior modification exercises are probably well worth it. Unfortunately couldn't see a lot of "real" info, a lot of pseudoscience or things that look well-researched but don't really hold up to scrutiny for me. You can find a research study to back whatever you want. If it were my money, I'd probably start with buying a book before I chip in for the dvd's or supplements.
If I keep starting over, eventually it will stick, right?
