Answer 1

You do not feel hungry when you need to eat, tired when you need to sleep, bladderful when you need to urinate, etc.

Your body does not wait until you need to do something to trigger you to do it. It wants you to do things regularly and conveniently to avoid a crisis.

Humans evolved as hunter/gatherers who needed a long time to get the food they needed to survive. So we feel hungry when we do not need to eat but an eat, so that we have time to get the food to eat.

Imagine it took 8 hours to get a meal together instead of just going to your kitchen and eating in 5 minutes. You would want to feel hungry 8 hours before you needed to eat (at least).
