I didn`t go to meetings but I did join WW online, and use the online tools for tracking food etc. It`s a great program for teaching you about portion sizes and making better choices. What I didn`t like was the cost. There are many free websites that provide basically the same service. I am currently using www.sparkpeople.com to track my food and weight and I like it better than WW.
I didn`t like the idea of having to go to meetings and be weighed in so this works for me. It`s much easier to be accountable for what goes in your mouth when you`re keeping track of it.
