The current system of running out of food cannot be named friendly, all troops are fed until food is out, then all that cannot be fed from production starve.
The way starving troops are moved to the hospital make you defender go first to be replaced by offensive troops.
There would be a relief when the hospital finally would have an option to treat or not treat certain troops.

It would be nicer if in the last say 5 hours every 30 minutes 10% of troops would starve.
you can discuss 10% of all troops or 5% defender + 5% offensive or or 10 % of troops that are above the food supply.
This are two questions in one
1 change treatment in hospital
2 change running out of food problem.
and of course wasso is right, don't run out of food, but real live comes distracts sometimes to long from the game and it is hard when you are 5 minutes late and obstructed by loads of adds making you see your troops starve without control to solve it. You have to wait until the game lets you take control again.
