The Human Body's Hybrid Metabolic System

The human body is adapted to an uncertain food supply. In particular to foods that change seasonally, and both feast and famine. Historically, years in which food was not short rationed at some time were unusual. The ability to carry a bit of extra fat was an advantage.

The in agricultural societies, the hybrid metabolism, burns glucose in times of plenty, and lipids in times of hardship. In herding or nomadic societies, lipid metabolism was normal, and only when they lost their livestock or when hunting failed, were they forced to buy food and rely on carbohydrates for sustenance.

For forty years efforts have been made to prove that then recommended low-fat diet was indeed healthy, with mixed results. It was the Women's Health Initiative (Published 2006) that finally demonstrated that at least for older women the recommended diet "has no health benefits."
