Hunger in H&H is a bit confusing. In most games and in real life it's a bad thing to be hungry, but in Haven you want your hunger bar to be as low as possible so that you get as much FEPs as you can from your food. At the same time we have "energy" that is regained by eating, and a low energy bar can really hurt you.
So I suggest renaming Hunger to Appetite or something similar. It is much more intuitive that having great appetite will give you more benefits from eating, and that your appetite isn't going to directly hurt you no matter if it is high or low.
