I am not disputing or addressing any of the benefits of your dietary regime to your health or well being. Personally, I think if it works for you, then do it. The ONLY thing I am going to address is some of the comments I have snipped below. That is because I am a paleoanthroplogist and what you have written here does not, in any way, agree with morphological, physiological, anatomical or genetic data.

This is not true. By the way are you referring to Upper, Middle or Lower Paleolithic? There were huge cultural changes between these. At any rate, there has been evidence that may push cereal and grains back 10,000 years in the human diet. I am not saying this is good or bad, just that they are finding things:

In Kalambo Falls, a site dated 200000 BP-they found nuts and seeds along with evidence of fire usage.

Our intestinal structure and length is that of a carnivore- like a big cat, and nothing like an omnivore like the rat or pig.

Our teeth are pure carnivore, they have a continuous enamel coat, are quite sharp, erupt once and do not grow or get replaced just as is the norm for animal of insectivore lineage. They are utterly unlike the complex teeth of herbivores and omnivores- whose teeth grow throughout life.


While it is very true that speech has helped shape our brains, larynx position and even not being able to eat and breathe at the same time, our teeth are not at all like carnivores.

We have spatulate incisors, small canines and low grinding molars. Nothing at all like carnivores who have small incisors, sharp long canines and often carnassial premolars. and I don't know what a "continuous enamel coat" means. However, the thickness of our enamel has shifted from thicker to thinner. A thicker enamel indicates a diet is or evolved from hard to chew foods that would wear down enamel-like nuts, seeds and grasses. THe earliest apes are like this as.

Our intenstinal structure has a reduced cecum and is, indeed, evolutionarily adapted to digest meats. Our cecum reduced, partially, to free up calories that would have gone to a more specialized digestion to allow for bigger brain development. However, that did not mean that we gave up being dietary generalists in order to become pure carnivore. It does mean that we expanded our diets to include more high quality meat foods that were easier to digest. Gave us big brains. Very cool.

The gorillas are completely vegetarian, up to 90% of the chimpanzee diet is fruit and pith. However, there seems to be an increase in hunting with chimpanzees during certain months of the year-at least with one observer

Again, I am not arguing your results, nor am I making a case for any type of diet. I am just trying to correct some errors I noted.
