I tried WW a while back. I was doing regular exercise, only about 30mins 4-5 x a week as well as following the points system, no meetings or anything though. I did it for a month and I put on half a kg!
I have heard heaps of success stories though, and maybe I was doing wrong things since I didn't go to meetings etc.
Right now i'm doing DYI. Sensible eating and lots of exercise and its working for me so i'm sticking to it
If WW worked for you last time then go for it! I buy some WW stuff like low fat sauces, ice-cream etc.
Saying goodbye to calorie counting AND scales for a while.
Just enjoying the new and improved healthy me and embracing my new lifestyle!
