But why do they eat too much? Two things to consider: higher fat meals can make you feel sated sooner, so you eat fewer calories. Also, there is evidence that carbohydrates trigger an insulin release which activates a hunger response.

I never understood the satiety argument. Fat also packs more than twice the calories of carbs. It needs to fill you up twice as fast or keep you full twice as long for this argument to work.

Besides, the body takes about 20 minutes to send the first "I am full" signal anyway. I can go through the majority of a large pizza within that time with my "normal" eating pace.
