You're right, there's not much fatlogic in the post, except for the one that allows him to laugh at those fatter than him while being fat. He's perfect for r/fatlogic, which is full of fats like him, fats who are self-aware to recognize they are fat and unhealthy and it's their fault, but who think they are fine and immune from fatlogic. In that sense, they're the worst kind of fat.
