Why do you snack more when you don't get enough sleep?

ANSWER

It makes sense that the longer you're awake, the more time you have to eat. This can lead to something called the "fourth meal." But even if you're not adding extra meals, more snacking throughout the day adds extra calories and can lead to weight gain.

Before you grab something to tide you over, ask yourself if you're truly hungry. If not, instead of eating, try to drink some water or go for a walk.
