                                An average adult human stomach can hold up to 1-1.5 liters of food, which directly influences how much pizza can you eat in one sitting before feeling uncomfortably full. Your personal record will depend on more than just stomach capacity, though, including the type of crust, toppings, and your personal appetite.
