I'm kinda hoping the reason you haven't done this yet is that you're planning on making a NOT AWFUL hunger system, but either way a nice stop-gap between now and then would be an option to eat food without it giving FEPs, hunger, or satiations. Most elegant way to do this would probably be it only giving FEPs if eaten at a table.
An almost as good, but definitely worse easier alternative would be to make certain foods (butter porridge, roast hoppers, everything from trees, honey gruel, grub-grub, mushroom spits, etc) never give FEPs or hunger.
Every time I leave my base I end up eating like 10 butter porridge not on a table, which is like 20% hunger. I like to leave my base and actually play the game a lot. Actually playing the game is noticeably making my character weaker.
