It depends. I'm not a big eater but I've at times ordered a 45 cm pizza. While I wouldn't finish it all at once, I'd probably finish it in half a day or so. Usu

It depends. I'm not a big eater but I've at times ordered a 45 cm pizza. While I wouldn't finish it all at once, I'd probably finish it in half a day or so. Usually this was after not eating for at least 24 hours, or after enjoying a particular substance. It definitely did not leave me feeling happy in the longer term though.
