This is my friend Doug. Doug recently went "paleo," paleolithic that is. This is a diet that recommends we go back to eating like cavemen- meat, seeds, nuts, berries, and vegetables. Carbohydrates are merely an invention of agriculture and are something that we did not evolve to eat. Check out the website: http://www.livingpaleo.com/
Sorry, Doug, but you're a primitivist if I've ever seen one.
