I haven't heard of it but I think it is a lot of money to spend. How is Atkins working for you ? I , personally refuse to spend a lot of money to have someone prepare food for me, when I can do it myself, so much cheaper.
I know of a couple of people who have been on it and they did lose a lot of weight but I think you have to be really dedicated to do it. Its a lot of money to waste if you aren't and a long time to go without eating real food.
