William Wolcott is the one who wrote the book I have, and I believe hes the one who refined it.
its based on people unique body chemistry, and there are three seperate "types" most people fall into, protein type, carb type, and mixed type.
according to the test you take, I am a protein type, and my diet should consist of 40% high purine proteins 30% fats and oils, and 30% specific low starch carbs.
In a nutshell its based on the types of diets our ancestors ate before frying, processed grains etc. its similair to Dr Gerson diet which has been shown to cure cancer and adult onset diabetes although gersons didnt include meat.
