I tend to argue that it absolutely requires effort to keep eating that much. Left to my every whim, there is no way I could consistently overeat to the point of their size. Case in point, I've just come off a couple of high calories days and I am very, very ready to stop eating so much. For me to gain weight from this point would mean actively pushing through a lack of hunger.  More to the point, treating the brake pedal as a footrest sounds just like the kind of ignorant and oblivious thing fats do. Point taken, though. Just imagine it's the hand brake, then?
