The answer is clear: live as though you are a free-ranging, adaptive human
being, not like some animal being fattened in a pen for the kill.

Live as though you are in the world that existed before the invention of agri-
culture. There was no grain or cereal or manufactured food in the ancestral envi-
ronment. Our ancestors ate fresh fruits and vegetables and meat. They got no milk
beyond the age of 4. They ate no cereals and consumed no vegetable oils. Their
diets were not particularly low on fats; indeed, for a few million years prehuman
hominids may have lived on the fatty bone marrow and brains of scavenged kills
more than on fresh meat. Even when they became premier big game hunters, hu-
mans preferred the fatty cuts of meat because the wild animals they hunted were
very lean. Modern meat contains around 33% fat as opposed to 4% fat in wild
game.
