From my own history with disordered eating, I can tell you that ignored hunger goes away after a while. For me, it's at about the 36-hr point. After that, my stomach no longer hurts and I no longer feel hungry. But my vision starts to get blurry, I get dizzy, I lose muscle coordination, etc.
So even if you're not hungry at that point, you still need to eat. Eating fixes it. You should know about what kind of portion is normal for you. Keep eating those sized portions at the right times for a while even if you don't feel hungry.
