I'm doing WW and have lost 6kgs so far. I love it purely because it's a long term life style change and not just a quick fix. I dont feel like im on a diet, i feel like im being healthy. Definitely worth the money. I actually signed up after I had ds, then cancelled my membership because i couldn't really afford it (it was the one where you attend meetings) but I still have all the stuff and it's easy as to follow on your own
