I read all of your posts before adding my 2 cents worth. I was doing WW Flex Plan prior to this. WW has a long established history and it seems that everyone on the planet (probably the moon too) knows about WW. However, I was allowing myself to eat too many "not-so-good-for-me" foods while following that. It's not WW's fault, it was mine. Having said that
initially I actually stumbled onto this forum within 3FC's. I followed it for about a month and I got the book, read it and decided to do a semi-Phase 2 for about 6 weeks between Thanksgiving and New Year's before actually doing Phase 1.
I decided to follow South Beach for two reasons
1) health- I had been beginning to show telltale signs of heart disease and diabetes for a couple of years which this food plan specifically addresses---the first of its kind that I am aware of.
2) I read the food list very carefully and it had enough of the foods that I already liked to eat to "convince" me that I could stick with it.
Granted, I did have to re-read the food list over to get some of the nuances like some things are portion-controlled and some are not. However, I would say that I feel better, I have more energy, I look better (some people say younger-bless 'em!

) and I am more and more convinced that this is the way for ME.
I have just decided that rather than try to defend South Beach or any other diet/food plan or whatever, I let my actions speak for themselves. My sister has commented about how healthy I eat. This past Sunday she "treated" me to an all you can eat buffet. I've been to better but a piece of pie comes free with the meal so she went ahead and picked one out for me. I had two bites, said I've had better and pushed it away. I thought the look on her face was "priceless". Only because of being on SB was I able to do that without exercising much willpower (something I had in short supply before when I was overloading on processed foods and getting the "carb crazies"). She said to me, boy, you sure eat healthy.
I am really sorry that some of you got entangled in those no-win debates. Again, I agree that the best thing to do is go where you know you are understood and the rest of the world can eat their pie, if that is what they want.
