UO is a realistic MMORPG. Food and cooking are being neglected in most shards. We are trying to make it more funny and realistic. We relate the hunger level to player's strength.
When player didn't eat for a period of time. He/she will receive a "You feel hungry!!" message above his/her head. 80% of strength would be left. If player doesn't eat immediately, he/she will get a "You are empty!!" after some time, and 60% strength would be left. But if the player still don't eat anything, he/she will finally receive a "You are starving and losing your mind!!" message, only 40% of his/her strength would be left.
