Basically I no longer can. They took my stomach out when it perferated last June. My esophagas is now directly attached to my small intestine and so that limits how much I can eat.
Before that though…
I don’t overeat, and as someone else said, I usually end up undereating due to laziness/lack of time. Student here, so fitting in real meals while rushing from class to work and back again doesn’t happen very often. Plus, I’m kind of broke, so my food budget is quite strict. I know that that box of cereal has to last me a week, and that frozen pizza’s gotta be good for 4 or 5 meals, and beer isn’t free, y’know. So I don’t have the time or money to overeat.
As for holidays, I’m the only vegetarian in a family of major carnivores. So, there will be a few nice side dishes for me and I’ll make up a nice big salad, but I’ll eat an average size meal.
