Disagree. I lost that much weight eating better and exercising. Fat people always have to make excuses (I can call people fat because I was one once....kinda like a black being able to call another black a n***er) as to why they can't lose weight. I'll never, ever go along with the notion that eating healthy and exercising is not the way to lose the weight.
I went on the Health Management Resources diet (HMR) (otherwise known as the Healthy Solutions Plan) and have never felt better. It's basically a healthy eating diet along with an exercise plan. Nobody can ever convince me that there's a good long-term way to lose weight other than eating healthy. NO WAY! And, btw, about half my class at HMR was comprised of very very fat people who had once lost alot of weight on the Atkins diet only to gain it back a short time later.
