I mean... hunger is controlled by your Hypothalamus in the brain for the most part, not by the volume of food in your stomach, it only makes you feel hungry when your body doesn't have enough energy to burn conveniently...

Though... it can also be because your full and your brain would sense this, making the sensation of hunger disappear, replaced with the feeling of fullness.
