I've never gone and ate at specific periods of time, I eat when I am hungry and it's not uncommon to go for big intervals between food. For example when there is nothing to eat, late at night, I just grab a small snack when it's available and leave eating for the next day. My question was mainly about big intakes of food, after the point you know that's a pretty good size of a dish for my body, then continue to eat, so I don't bother a longer period of time with food. Am I wasting food after that or with my fast metabolism it's still getting processed?
