"You don't want to go stuffing your face with food every five-and-twenty minutes!" said to my teenaged or 20-something father and and a small bunch of his mates after they'd spent a very long time - possibly a day and half a night - on some hunting/shooting/fishing mission, which involved some mishap of getting lost. On returning to civilisation they were hungry, but whoever it was they had arranged to meet that evening had been well-fed that day and didn't feel the need to dine. It was repeated by my late Daddy whenever we complained about being hungry.
