That's only half the adaptation though. You can decrease the volume, but also decrease the frequency by sticking to a strict schedule. Don't _ever_ eat outside of the normal times that you should eat and your appetite at all other times will decrease. Your body learns. The next part is just my own made-up opinion but: I think this is also why you shouldn't under-eat because then maybe your body won't learn because it actually thinks its starving and so it won't adapt to the smaller volume and lower frequency.
