I have done weight watchers a couple times during my life. Every time I followed it, I lost weight. This last time, two years ago, I think I had a change in mindset, that I was tired of going up and down. I lost 30 lbs and have kept it off. It took me about 8 months total to lose it, but I kept dropping weight. The most important thing is to write down and track your points. Once I stop doing that, I fall off the wagon and can gain a pound or two. No more!!! I track. Follow it, it works. It's a lifestyle change. And it feels great to weigh what I did when I got married, again. :)
