I noticed that in a LAN world (I was a client, not the server) hunger will sometimes lower then regenerate a few times and act as if full. I then attempted to eat something, and I couldn't eat it. After switching to another item within the hotbar, followed by a few seconds, the "eat" noise was played and the amount I attempted to eat was subtracted from the food stack.
