If you need to somehow limit the food intake of each dwarf then you need to make more food.
I'm not limiting the food intake, rather I'm limiting how much food get moved around. Plenty of food, I just want them contained separately from rest of fort.
You should probably be clearer about the mechanism you used and the purpose of transferring food. Why is it necessary that one of the food areas be locked off from all dwarves completely?
Alternately, put wells and beds in any larders where dwarves might get trapped so they don't die, even if they go without alcohol for a while.
Purpose is to have dedicated rooms/workshops to limit how much they runs around, with how much bad luck I have with forgotten beasts, hahaha. I'm also experimenting with material transfers and barrows aren't good enough, the spam of inaccessible material's too frequent if they're not sealed in somehow. The layout is pretty much a few work shops, a few stockpiles and the workers' bedrooms and dining room (with food and drink stocks for a few months ) sealed off from rest of fortress, with only raw material, food, drink and finished product being transferred in/out with as little creature movement in/out as possible, including dorfs.
Originally I just used levers and doors with mechanisms, and manually had them switched up while watching to make sure they're out of the rooms. I want something more automatic, and need less attention. The only issues I've ran in with what I'm running now is is that sometimes the workers get trapped in the 'transfer rooms', and I don't see any obvious ways to keep them from getting trapped for the season or so.
