Actually, in one of the first episodes of Secret Eaters, there was a fatass who only ate after midnight. But his "meal" would be two cheeseburgers with lots of fries and MAYONNAISE over it. That's right, fries with mayonnaise, I get sick just remembering it. Of course, some more beers to wash it down. It was estimated that he was shoveling 3000-3500 calories in just that meal. He'd even fall asleep and still keep eating!  NEVER doubt the ability of fatasses to eat.
