Mark, and other caveman diet experts, believe that grains contain a protein that is unfamiliar to our biology, making it inappropriate for human consumption. This flies in the face of everything we have been taught about the essential need for whole grains as a staple in our modern diet.
My advice: Do what a true caveman would do – decide for yourself. Take a week away from grains and see how you feel. If you are losing weight and gaining energy then stick with it.
From what I have experienced with thousands of people around the world, you will most likely find that you do not function well with the added grains after you remove them and add them back in.
