I would suggest starting with walking first and building up to running and walking and eventually running, if that's you're goal. What about those devices that deliver electric shocks to your muscles. No magic pill yet. Chromium does not do that. It was advertised to increase LBM in people who did resistance training, but all the studies did NOT support this claim.
Competitive athletes are generally the ones who have huge food needs.
I heard on T.V. the other day that there is some pill called the Fat Trapper. It is said that you can eat whatever you like and by taking this pill all you got to do is exercise. No, that pill does not do that. Take a look at my message board for excess weight. I believe what you are talking about is Chitosan and I have posted a paragraph about that product and others have posted their experiences as well.
