Where Do Metabolic Types Come From and What Are Their Implications?

Quite simply, metabolic types come from our human genetic "pools" or more accurately termed Genotypes and Phenotypes.

Genotypes reflect the entire genetic constitution of a person distinguished from his/her physical appearance.

Phenotypes reflect the entire physical, biochemical, and physiological make-up of an individual, a profile that is determined both environmentally and genetically.

in effect, we have groups of humans possessing similar genetic characteristics based on an originai genetic "set" (or pattern), which has been modified over time due to the influences of environment. Simply speaking, we all come from identifiable ancestrai, tribal origins. (See "Ancestral Typing" in the Glossary at the end of this book.) Due to environmental variations such as climate, diet, lifestyle, and socialization factors, our genetic set has been further differentiated from its primal origins into other races and body types with certain genetic characteristics indigenous to each race and still others found in all races.

That which has been genetically delivered to each of us—individually, here in modern times—is a body type variation based on a 40,000+ year chronology of environmentally affected evolution. Whether your ancestors were hunters, gatherers, farmers, fishermen, savage warriors, peaceful citizens; whether they lived in cold climates, warm climates, high altitudes, low altitudes, etc., all of those factors have had a pronounced effect on what you are, as an individual, and what you require from the environment to be your healthy best.
