Is it normal to feel hungry after four hours?
Yep.Totally normal
Yes, feeling hungry after four hours is completely normal. How soon you get hungry depends on what you ate, how active you’ve been, and your own appetite.
Four hours is a very ordinary gap between meals or snacks. A meal that was small or low in filling foods may leave you hungry sooner, and exercise or a busy day can work up an appetite too.
People’s hunger rhythms vary, so there’s no magic number of hours you’re supposed to last. If you’re hungry, it’s fine to eat something.
