Latte31-I used to be a Weight Watcher member and I would love the motivational tools that they would use during the meetings to get you excited about weight loss.
They usually offer a bookmark for a 5 pound weight loss, and a key chain when you reach a 10% weight loss.
The nice thing about it is that they announce it to the entire group and everyone congratulates you. I think the accountability along with the support is what makes Weight Watchers work.
If you have a bad week, nobody chastises you and by going to the meetings you learn how to deal with temporary slip ups that happened to everyone.
