I found a book with a fat main character and it's hilariously bad. There was a discussion some time ago about how no one really wants a fat main character as a protagonist in media (movies/TV shows) because it's impossible to make them be active and realistic at the same time. I just read a book which attempted to make a fat man a hero, and it's a glorious trainwreck. The main character is a former NFL player (of course) turned detective, weighing in at 350 pounds. A brain injury miraculously gave him the ability to never forget anything, which is basically his only saving grace. He's rude to everyone, he breaks several laws, and several times he's an inconvenience cause he can't fit into spaces (like cars). But he discovers his solutions like he's House MD. He's also apparently the most emotionally stable person in the book, because the supporting characters are bi-polar.  But I literally could not stop laughing at the ending. Do you want to know how the great fat action hero defeats the villain? He breaks the chair he's tied to and falls on him, literally suffocating him with his fat. I'm not even joking about this. There are no great fistfights, no running around, not even a simple gun fight. No, some angry words are exchanged and then he 'tackles' (i.e. tips over the chair) the guy and smothers him with his fat.  Isn't he the best hero ever?
