I think its hog wash.. I lost 43 pounds once all while drinking 4-6 cans of diet soda the whole way.. Its your diet and amount of excerise you get that counts.. Some people say they worked out for 1 Hr at the gym.. Did they actually work out or did the pace around the gym talking to other people and really not apply them selves?? Its all about calories.. Burn more than you consume and you will loose weight..
