Yep. I lost 2 stones with ww, and I'm still maintaining my weight, only fluctuating up and down a few pounds. I'd highly recommend it as it's easy to follow and it works!
I do it online mostly as I wrk shifts so its difficult to go to regular meetings. If you join online u can go to the meetings anyway. I go to as many as i can, to get weighed and motivated. I went last sat, but didnt go for 11 weeks before that, n luckily i managed to stay the same weight!
