Loadsa reasons here too - to list but a few...

I will soon be able to go to the theme park and go on the rides without thinking I might get my a$$ stuck!

I am able to boast that my rings are swimming on my fingers to anyone who cares to listen!!

I am able to go to a store and chose the next size down

I can feel riteous when someone I know is stuffing crisps/bread/past and think - well you're making yourself fat and I'm making myself thin!
