OK, this is too all the girls in here talking about eating lots of bad food and still being skinny.

You seem to be almost proud of it, but if I were you I would start making changes for a healthier diet. Just because you aren't overweight, doesn't mean that you are particularly healthy and have free reign to sit on your butts all day eating junk. I would start taking care of my health before my physical appearance took a change for the worse.
