Most people can, Hannah. Most people just choose not to. And when they do lose weight it is because of vanity issueas rather then realizing it is dangerous to be very heavy. My father is almost 400 lbs. But he won't do anything about it. He got that way from bad habits, but he just sits on his but all day not doing a dang thing. Now who's fault is it? I udnerstand it is hard, but you should at least try, yah know?
