I have tried Slimming World and Weightwatchers at various times em, and if you stick to their plan you will lose weight but when you stop going to their meetings you will put it all back on again (well I did). Sqad said the most sensible thing in answer to one of my questions and that was to eat the same food but reduce the portions. If you can gradually get used to eating smaller portions you will be able to keep it up and keep the weight off. I am trying to count calories, but it comes to the same thing, reducing the portions.
