Okay, Food heals, so what I'm thinking is that now it'll heal slower, taking from the hunger bar and giving to the health bar. If it's empty you won't heal, but with no other side effects.
I really hope you are wrong about this. If that were true then there would have to be some other way to get health besides food. It would be ridiculous if you were on the verge of death and you couldn't heal yourself so you have to wait 30 minutes for you to get hungry again.
