No shit, if you regularly eat to the point of being near comatose - and are in such a visible state of physical distress because of it that people are alarmed - that's a fucking sign that you have a problem. And you probably do need insulin if you can't stop stuffing your face to the point of blood sugar overload.  And on top of this behavior being nasty and gluttonous,  can you imagine behaving like this at a work lunch? Like, eating yourself into a diabetic coma in front of your coworkers is something you really want to be doing? God, I know these animals don't have the capacity for human thought, but one hopes that some whisper of past humanity goes through their minds when it comes to not sabatoging their careers by porking out in public.
