I'm going to be a little late to the thread.
Pros for me:
- look good in a pair of underwear
- not get nearly as winded when I am sparring and performing kata in my karate class
- be a sexy-looking black belt (and make the other guys pay more attention to me as a woman, but not in the attraction-sense; I guess to just have them aware of what I am, coz right now I'm just one of the guys)
- confidence
- ability to wear boots over my calves (I got fat calves) and nice skirts
- get more flexible than what I am now (I can do a full side split, but my tummy's preventing my head reaching the floor on other stretches)
- look like I have curves, rather than spare tyres
- feel as sexy as I look
- to show my family that I'm NOT going to be fat forever (everyone has their time, and my time is now)
and last but not least
- to set a good example for other girls and women who want to lose weight.
