The software is a tool (and there are a variety out there) but the motivation has to come from within. Congratulations on meeting your goals.

I'll bet you feel a lot better as well as look better. There is, indeed, a health benefit to what you are doing.

My tool: I was introduced to the "Lose It" app for iPhone (loseit.com) last year by a friend who has subsequently lost 40 pounds. (His wife lost nearly 50.) It took me a few months of watching his success before I "got serious." The result is that I have lost 32 pounds in the last year. I am continuing on track for another 13-15 pounds. I am looking at my goal of 175# by late winter/early spring.
