There is a book on it. Dozens, in fact - here is one

<<The book sets out to explain how even top level athletes can benefit from natural eating.Whilst not strictly adhering to everything Paleo, they are prepared to bend the rules slightly to optimise the athletes before, during and straight after training needs.>>
Plus lots of barking mad US websites. Here is a big list

Much of this stuff is based on misty-eyed romanticism and abysmal ignorance about anthropolgy. E.g.
<< It is argued that until the Paleolithic era came to an end and Neolithic and modern era foods were introduced by agriculture and industry virtually none of today’s chronic diseases existed.Coronary heart disease, type-two diabetes, hypertension, obesity, colon, breast and prostate cancer were not the killers they are today. Being eaten by a woolly mammoth was probably the number one back in those days.>>
Evidence? You could fit all the paleolithic skeletons ever found into a medium-sized room, with most of them just fragments. And mammoths were vegetarian, As Any Fule Kno.
