I have joined Weight Watchers on two seperate occasions, the first when I was younger, I found the points system easy to follow, and the meetings very inspirational and motivating. THe second time I joined, (about 8 months ago) was a different story. My leader was a doofus lol he would stand in front of the group and say oh, i gained 2 kgs this week because I pigged out and drank with my sons..... i thought, you are supposed to be inspiring me to be like you?
aaarrgh lol I also found that the price had gone up, and found it expensive, when you look at membership, weekly fees, food etc. I also found with the points system that I had too much freedom (dont know if that makes sense lol) It was like because their motto is you can eat ANYTHING so long as its within your points, it made me justify that i had just had 2 icecreams and a bag of chips, cos it was "in my points" the last few months I had been continuing ww, but at home, and weighing myself once a week, which does take a lot of willpower and self control, but I feel really proud that I have been able to continue alone.
So good luck whatever you choose (sorry so long xx)
