Editor's Take:

Jon Brower Minnoch's case changed how doctors understood extreme obesity. Much of his weight was fluid caused by heart failure, not fat alone. That showed how illness and weight can be bound together. His story was told in record books, often as a curiosity. Behind the numbers was a working man who struggled with severe health problems from childhood. Medical teams learned from his treatment for years afterwards. His record has never been broken.
