Weight Watchers works very well for a lot of people, as long as you commit to it! The first time I did it I lost 24 pounds in about 3 months. When I stopped counting my points, I slowly gained back about 5-7 pounds, and maintained there for awhile. Then I started taking a certain medication and rapidly gained back the remainder of the weight I had lost plus another 10 pounds, in less than two months, and have continued to gain. I have tried to go back on WW twice, but I haven't been able to stick with it. And that's no one's fault but my own.
When I last attemped to get back on the program, they had changed it so you could do counting points (easy, you'll learn quickly to estimate portion sizes and how many points a food has and won't need to rely on books or internet to count your points) or another program, which I thin kwas based on eating certain foods? I don't quite remember.
Anyway, WW is more of a lifestyle than a diet. To be successful, I had to relearn how to eat. For the first week or so I felt like I was starving, because I was used to eating until I was "stuffed". After that first week, my body became used to me eating smaller (more appropriate!) portions, and I no longer felt hungry. AND I felt incredible, because I wasn't having that weighed-down, rock-in-my-tummy/I ate too much! feeling I got from eating too much. Learning to eat slowly and savor my meals was great!
I really need to get back on the WW bandwagon!
