That's an interesting division, because I also think of "first" and "second" hunger, but differently.
What you describe as "actual hunger" is what I think of as "first hunger", which is just triggered by mealtime, and goes away after 30 minutes to an hour as you describe.
If you ignore that sensation of hunger for about a day, you start to feel a deeper sensation of hunger which doesn't go away, it just keeps growing.
