I totally rate SW over WW but it is years since I did WW and I think it has got better since then. Agree that SW large portions are great when you are on diet but if you fall off the wagon big time you take a huge appetite with you, which isn't so good. On the plus side though, if you really get into it, get the magazine etc there are some fabulous recipes. I have been through my second pregnancy and three months none dieting grace before taking it seriously again and despite not dieting for a year, still pretty much only cooked slimming world meals through that time - I can hardly believe it but nearly all my run of the mill weekly meals are slimming world ones, and my whole family is happy eating them. I think that says a lot about the flexibility of the plan and how it can be about long term lifestyle change - not losing weight then stopping the diet and piling it all back on again!
