I was able to get food and retain it. Thanks for looking into the matter, for now it seems to be resolved. I hope it stays that way haha.

On the UK server my character did retain his hydration. I have no food to test hunger and it seems I am very close to death from starvation already. I Will try to get someone to bring me food.

I was able to drink some when I logged in today. Still starving and waiting for someone to bring food to my location. Also On the US-1 server for DayZ Colony I had the same issue about 30 minutes into a new spawn. Tried to eat human steaks and my hunger would not update, re-logged and was starving/thirsty.
