I have just done a week on it and have lost 4lbs..considering its my * week, Im impressed with it.
To be honest I didnt find it as restrictive as others do...you just cant have the unlimited quantities of fruit and veg etc...everything is limited.
I stick to plan 100% and must admit that it annoys me when people think that you must be cheating if you either gain weight or stay the same each week. If I have cheated I will say, as the only person that I am cheating is myself and after paying a lot of money out for a gastric band...why would I want this to fail????
Anyway, Im not going to get into this, but wanted to add that FF is an option that is given by your Consultant if you are stuck, but can only be offered by your Consultant after they can see the efforts that you are going to.
