I've eaten whole pizzas before, but the difference between these fat people who constantly proclaim about 'listening to your body' and us, is that they have fucked their body up so much they'll eat another whole pizza three hours later, while you and I wouldn't eat for a day (give or take).  It's like telling a methhead to 'listen to your body, it knows when it needs meth or not.' I mean, who the hell is stupid enough to think that is good advice?
