For example, fasting is taking from my fat and glycogen stores 9200 kilojoules of energy to use for consumption and production, while if I had eaten that much beans today instead, I would have paid about 10,000 sats plus an additional 900 or so sats sales tax to California so they could keep stealing from and killing people and mismanaging healthcare.
This is the bare minimum if using the cheapest decently healthy food available. Using this info and other health parameters, I can calculate how to bulk and trim my body tax efficiently to reduce my support of the state longterm. Fasting makes more efficient use of protein, so I may be able to get away with saving money by eating cheap vegetarian sometimes and still gaining muscle, and reducing the sales tax I pay, all at the same time.
