> Can you eat an entire pizza and still be hungry except it's physically painful to eat?

Same as the other poster, yes, but I can also still eat more without pain if it's a Large Domino's Pepperoni Pizza. If it's the Dominos "Deep Dish" though, that's my maximum. I can regularly put away a large Little Caesars pepperoni without trying, it's just a "normal meal".

The difference between me and people fatter than me is that after a large meal like this, my body stops "demanding" food for 1-2 days. Thats what keeps my weight in a +/- 3 lb range.

I know the difference because every once in a blue moon after I turned 30, my body's hunger signals will make me un-satiable. The experience of suddenly being unable to diet was jarring. I've managed to fix that somehow, thankfully. But it was very, very clear over several weeks that dieting was entirely beyond my control no matter how much willpower I had.
