Want less food to spawn

[Emton]

I started a new sandbox game with food set to "extremely rare" yet every house I went in I would find at least 3 or 4 cans of food. Well to me that's just not rare enough, does anyone know what I could modify to get less food to spawn, I want to try something like 75% less food cause I want to actually be worried about finding enough food, maybe even once in a while starving to death if I venture too far from the town or be forced once in a while to have to forage and make setting up gardens actually important.

 

Edit: Oh I found out that the amount of food is also controlled by how many months after the apocalypse, so setting to 5 months after seems to give a better balance.
