Personally, I think if other plans work for you, then...AWESOME! To be honest, I'd love to be able to do a low-fat diet and have tons of fruit and an occasional bagel. But I can't, so I don't! I love the feeling of self-control I get from low-carbing. I normally have really bad cravings and unstable blood sugar, so low-carbing is perfect for me. I do realize, however, that it's not for everyone, and for some people WW or others is better.
