Principles of biological scalability, especially the principle of the minimum https://en.wikipedia.org/wiki/Liebig%27s_law_of_the_minimum … along with principles of social scalability https://unenumerated.blogspot.com/2008/07/hampton-sides-sheds-light-on-mancur.html … https://unenumerated.blogspot.com/2017/02/money-blockchains-and-social-scalability.html … explain some of the most important patterns of history. /1
Applying the Sprengel/Liebig principle of the minimum to human food production & nutrition, a society can be protein-rich, and thus limited by its carbohydrate & fat intake (i.e. calorie-limited), or it can be rich in carbohydrates or fats, thus limited by its protein intake. /2
Our hunter-gatherer ancestors had poor social scalability because they were roving bandits, frequently at war with each other. Their typical diets, compared to ours, were heavier in meat, & thus more limited in energy (carbohydrates & fats) and less limited in proteins. /3
Stationary agriculture was carbohydrate heavy -- abundant in energy but relatively scarce in protein. Permanent food sources enabled stationary bandits, an innovation that allowed social scaling to far greater population sizes and densities than roving banditry. /4
The downside to stationary agriculture: the protein-limited grain diets of typical farmers were unnatural & poor compared to the protein-rich diets of their hunter-gatherer forebears. Genetic adaptation was only partial. /5
Alongside the stationary carbohydrate-rich (and thus protein-limited) cultures were the nomadic protein-rich cultures, far more limited in social scale, except when, as with Mongols, Arabs, etc. they conquered & led the social scaling institutions of stationary societies. /6
The frequency with which sparsely populated nomads conquered populous stationary societies seems paradoxical until we realize that nomads diets were much closer to our foraging forebears', giving more muscle & brain power, offsetting the poor scaling of roving societies. /7
Stationary pastoralism https://unenumerated.blogspot.com/2011/05/lactase-persistence-and-quasi.html … combines the social scalability of stationary ag with a diet much closer to the protein-rich diet of nomads & hunter-gatherers. The ag & industrial revolutions happened first in regions most advanced towards stationary pastoralism.
When you say “fat” do you mean animal fat or vegetable fat? When meat is consumed in the traditional way (the whole animal is eaten), one obtains protein (tissue building) *and* fat (energy).
I mean a plant-heavy diet (e.g. traditional stationary ag) is protein-limited, due to excess of catbs and oils, whereas an animal diet (pastoral or most hunter-gatherers), despite having some fat, is protein-limited.
I’m not sure if I understand, both are protein-limited?
Sorry, the animal part should read calorie-limited.
From an evolutionary point of view an animal diet would not have been calorie-limited. The body can obtain plenty of energy by burning fat, which would have been in plenty supply in a traditional animal diet. People would have eaten the *whole* animal - plenty of fat on a pig :)
