Forgive me for not understanding, but why is hunger level not tied to your current energy?
To get the most out of food you want to keep your hunger level low; however as it is not tied to your energy level you are forced to eat, as your energy level naturally goes down whilst playing the game and doing things (to replenish your energy you need to eat or face death as you start to lose health from having a low energy). Your hunger level seems to go down ONLY via RT minutes, this systems current implementation just seems to punish actually playing the game and reward being logged off or just afking, as by playing the game and eating (to avoid death) means your hunger level will continuously rise, meaning you will get less and less benefit towards FEPs the more you actually play the game.
