I realized the same thing when I saw this and the x-ray comparison. I think this is a graphic artist's creation, based as closely as possible on a real person. It's amazing to think that every fat person has the same bone structure as a thin person. That skeleton must hold so much extra weight, hanging off at the worst angles. It's amazing that the stomach can be held in place at all, until it becomes a fupa. It's so clear that the body is not intended to be fat.
