The Weight Watchers program is one of the first diet programs to have major nationwide success. Followers can eat anything they want in moderation. The diet uses a point system, with each portion of food being equivalent to a certain number of points.
Points are limited each day until the diet weight goal is met; followers are also encouraged to attend group meetings to find support with others participating in the program.
Jennifer Hudson and Jenny McCarthy had a phenomenal amount of success with the diet program.
