A lot of people seem to cite a bad upbringing for their weight, but I was the complete opposite. I was soooo skinny all through high school while my mom continued to cook nothing but extreme health food for me, and while I was a hardcore gymnast. Once college came, it was bad news. I think having it all done for me growing up, I hadn't learned what food can do to the body, I just stayed really skinny (and muscular), with no effort. It took me a long time to realize that I had gained weight, why I had gained weight, and what I should do about it.
