I would still eat like a little birdie. I've never had much of an appetite. I do love mushrooms though, I go through whole packages of 'em. They taste great with a little lemon juice sprinkled on.
I doubt I would eat a ton. I mean, part of the appeal of eating is the satisfaction of being full. If you were never full, it'd be a hollow pursuit. Plus I don't want to be going to the bathroom that much... :P
