Obesity doesn't always equate to someone having a terrible diet or being lazy, just as not all thin people are uber-healthy. I know a girl who can eat crap all day long and still be thin as your average stick. Admittedly, there will always be lazy people, or people who are simply beyond the old diet and exercise.
I have an incredibly slow metabolism, which means despite eating maybe an apple or two and some coffee during the day followed by a dinner usually made of red meat and veges, I am overweight. If I so much as consider eating junk, I put on weight like THAT. I managed to get rid of the pudge for a year or so by spending an hour and a half on a treadmill every day and having all my meals planned. I don't have time to spend an hour and a half on a treadmill any more. It's a colossal annoyance.
