Taking care of yourself makes a much bigger difference than people like to admit. There's a woman at my gym who is sadly not at all gifted with a pretty face but she's damn near perfect everywhere else due to hard work in the gym.  I'd put her as a 9 easily.  On the flip side, I want to slap fat girls with pretty faces, especially if they revel in said pretty face.  If you just wouldn't eat so much you would be model hot, but apparently Twinkies are just too yummy.
