I absolutely agree. I always went with light cheese so this might influence things a bit too. But I doubt by all that much. I think that as a general rule I just never found pizza very filling. Not to the point where I think I could finish off a medium sized pizza on my own. But pretty close to it. And that holds true for times in my life when I was fairly sedentary and at least somewhere around the middle of the healthy bmi range. As I focused more on fitness I never saw much change in it either.  The only exception is when I started making it at home. Very light on cheese, avoiding excess sugar in the dough/sauce, and with a heavy emphasis on filling vegetables as toppings so that they're the heaviest part of the crust/cheese/toppings ratio. That was usually filling while sitting at a reasonable caloric count.
