I have always done the points diet. I don't think i could be limited by what I can eat like the core does. I love the freedom of being able to save up points for treat like a takeaway.
I much prefer the points system. I prefer the discipline of knowing that when my points are done, theyre done. I KNOW the core does work but I never see how ones that allow you unlimited food can work lol If I was on that Id take it to extremes Im sure lol
Like Dreaming I like to save points and be able to have a treat, or eat a bar of chocolate if I feel so inclined
