Hungry effect despite eating

Note: I don't know if this is a bug or an intended design change, but it is game breaking either way.

Short description: In Offline mode, eating Roasted Meat causes a Hungry effect within less than a minute.

Long description: The Hungry effect causes health to tick down constantly even without taking any kind of damage. By the time there is a minute left on the countdown and it is time to eat again, the health is below 60. This means an invariable one shot kill in any boss fight and little to no chance, if standard encounters overlap. The Hungry effect occurs regardless of the meat or fish used to create the food, at least on starter level. And no, I do not have the means to work around the malfunction by eating several food items yet, since I just started a new toon. Thank you in advance.
