Like everything else in this world, there's probably a work around to this. A person could probably go to a doctor and get a note saying despite being obese, there are no other health concerns. For example, I didn't get my wisdom teeth removed before I went. My dentist said they would probably never be an issue. I still have them all these years later (I'm 35) and have never had an issue. Despite being an "extremely large person", I have no other health risks. No heart issues, no blood pressure issues, no diabeetus concerns, nothing to worry about at all. But I have always been active. I have a physically demanding job, I've always played sports, I'm constantly out playing with my kids and wrestling with them, etc.
