So, it's simply impossible to starve currently in B42, anyone who do, is genuine retard.
One brown-white cow can give you about 5L+ of milk per day when pregnant. Which already insane and remove need to look for water, as, you have milk that both give colories and quench thirst. But, you can turn 5L of milk into butter that you can eat, if you brainroted redditor, or add in your cooking as seasoning if you are human. If you have some chickens as well, then you can endlessly make stir-fries with eggs and butter, and your colories will be always positive. And if you star to getting too much weight, you will simply stop adding butter for a bit.
Farming = endless food, which is realistic, beside part where milk don't spoil currently, and neither does butter, which wouldn't matter anyway, as long as you keep your cows healty and alive.
