I have been following WW for 5 weeks now and have lost a total of 12 pounds. I do not attend meetings because for the time being I live in Italy and there are none available to me. I have the material from the old 1,2,3 Success program that I am using, I belonged to WW when I lived in the US and attended the meetings, but I guess I wasn't really committed because I never lost more than 8 pounds. My material is well worn so I am thinking about buying the current 2003 material, there are lots up for auction on eBay. My sister is a member of WW, she has lost 32 pounds in 7 months and she is sending me some info and a points calculator as well. I think different things work for different people, I am at a point in my life that I want to get healthy so I am motivated to stay on program, but some people need that weekly meeting, I think it all depends on the individual.
Good luck!
