Answer 1

We don’t metabolize as much food while we are sleeping, because we are moving less. Just as you might be very hungry after a strenuous workout, the opposite is the case while we are sleeping.

Also, because the hunger would have to be strong enough to wake you up. We generally do wake up with more hunger than we went to bed with.
