    It's admirable to attempt to avoid all processed foods; but virtually impossible in our modern world, especially for those in large cities. It is also VERY expensive to consistently eat all organic produce, especially if you live in a large city. this is not an easy way to eat. I agree; eating processed foods in moderation or as little as possible is probably a good idea, though. PS: Cosmology, i.e. "The Big Bang Theory" is NOT how the universe formed :-)…and evolution is a farce. As our creator, it was God's idea for mankind to take care our world and our bodies. Why disease and breakdown in the universe? The result of sinful choices by people.

    Hi, i have 04 questions…

    1. Can i totally remove SALT…. will there be a side effect if we don't have sodium in our body? Can the sodium in fish and shellfish be enough in Paleo Diet..?

    2. How about spices like garlic, onion, ginger, pepper and the powder spices like turmeric, cinnamon, curry… are these spices allowed in Paleo Diet?

    3. I am drinking water with honey and apple cider vinegar every morning when i wake up one hour before i took my breakfast… Do honey and apple cider vinegar allowed in Paleo diet?

    4. Since Paleo diet is high in meat and egg, will this diet be safe to old people aged 50 and above. Will it not increase their cholesterol level and their blood pressure??? or Paleo diet is only for young people aged 30 below…?

    To all the people who say "he's not even fit" … That is because your idea of "fit" has been drastically skewed by the fitness industry who use genetic outliers to sell supplements, gym memberships, clothes etc. the human body has evolved to carry body fat for survival. It also has NOT evolved to carry massive amounts of muscle. That would have served as a survival disadvantage. So before you call this guy "unfit" please try to understand genetics and biological evolution first.

    Human milk is, interestingly, much higher in lactose than cow, goat, sheep, buffalo, or camel milk, which are all traditionally consumed milks.  Mare's milk, still consumed by the herders of Mongolia, is the only milk used by humans that compares in levels of lactose to human milk.Weston A. Price found cultures consuming diets high in dairy products with excellent physical development, superb dentition, and no cavities, including isolated Alpine villages in Switzerland, before roads were put in.  Their diet, he reported in 'Nutrition and Physical Degeneration', consisted almost entirely of milk and other dairy products such as cheese, and bread made from a fermented rye- which was always eaten with a thick slab of cheese.  These villages had neither police nor doctor because, they said, they had no need for either.  The men from these villages were well known for their outstanding performance in national athletic contests.  Interesting, eh?Many other cultures traditionally ferment milk (kefir, yogurt) and/or make it into cheese, which changes the milk and particularly the lactose via the action of friendly bacteria.

    The dairy issue is interesting.  Wild carnivores will consume the udder of prey to obtain the milk within before they consume any other part of the animal.  (This has led to speculation of aliens dissecting cattle when they were found dead and otherwise little or untouched except for the udders being entirely gone.)Milk is readily consumed by adult animals of every species I have ever seen offered the opportunity: cow, goats, chickens, turkeys, ducks, sheep, and of course, dogs and cats.  *There is a huge difference between pasturized industrially produced milk from cows on a grain based diet,, and fresh uncooked milk from healthy dairy animals on 100% pasture and forages, aka 'grassfed'.*Also, traditional cattle breeds produce much higher percentages of fat and other nutrients in their milk than the 'standardized' homogenized milk sold in stores.  For instance, the 100% grassfed Jersey milk we have access to runs from 6% to over 7% butterfat- compared to 3.25% in the standardized milk in stores.Sheep milk is much higher in fat content than commercial industrial cows' milk, at around 7% – but well managed traditional Jersey cows can reach that level of fat content in their milk, as can Devons and other traditional dairy cow breeds.

    Very good information overall.  Goats & sheep were providing milk (as well as meat, organ meats, fat, bone marrow, hides, etc)  to humans long before cattle.  Prof Cordain thinks 'outside the box' in many ways, but his world view has been shaped more than he is aware if he equates the domestication of cattle to the advent of dairy consumption.  It is generally agreed that sheep were domesticated +/- 10,000 years ago.  In addition to meat, fat, and hides, the milk from these animals was also used.  Like the Masai of Africa, early people knew they could harvest the milk (and in the case of the Masai, also the blood) and they still had the animal.  Obviously, this is not possible when harvesting the carcass.Goats were also domesticated and used for milk production around the same time.  Camels, yak, reindeer, and mares are among the other animals that were commonly used by some cultures to produce milk used for human food, in all likelihood going back farther than the 6,000 years generally quoted as the advent of dairying.

    At first, I though that this product was all hype because I took it for 2 weeks without any results. However, I am really glad that I decided to keep on taking it because when it finally worked, it worked wonders! I have lost 2 pounds every week since then ! have used Weight loss green store tea

    This guy's not fat! People are trying to say he's got a pot bellie? WTH? Loose skin around your neck is genetic, it's not fat. I'm sure this guy's BMI is right on target. Unless you have some obsessive/anorexic issues..


    BS diet.
    why exclude whole grains when they are super healthy?
    high in fiber, low GI, high in minerals and vitamins. gives steady energy and makes one feel full longer which is useful in weight control. oats esp boost the immune system.

    load of BS. whole grains are super healthy. they boost the immune system and decrease the chance of allergies and provide minerals and vitamins. meat should be eaten in moderation. eat 3 whole fruits a day and 2 servings of veggies daily.

    What a "World's #1 expert" on whatever subject… looking all healthy and vigorous.

    If followers of the paleo diet get their "scientific data" from this non-sense guy, I can see, why they themselves have no clue of what they are talking about.

    So many things in just one interview…

    To mention just a few of them:

    @ 27:58: "The behaviour of eating only plant foods – and not eating animal foods – is lethal… it'll eventually kill you… and it produces disease and, so… reproduction into adulthood… then is going to… be… impaired… so people that don't eat meat won't reproduce, so… that – if it's a genetic thing that is causing the behaviour – that'll be a problem…"

    What on earth is this non-sense man talking about?
    Where is the scientific data confirming this platitude?
    Please, don't go around making things up in your head – and tell them as being reliable data. There might be sensitive and naive people actually believing your words to be true.

    @29:00 you talk about studies done on mortality rate among vegetarians/vegans compared to non-vegetarians.
    That vegetarians/vegans are not "healthier" than non-vegetarians – though when it comes to at least ischemic heart disease, the 1999 study:,
    concludes that vegetarians/vegans have a 24-26% lower mortality rate – compared to meat-eaters (2009 study has 19% lower for vegetarians compared to meat-eaters).
    2009 study:,
    concludes that the study is not large enough to exclude small or moderate differences for specific causes of death, and more research on this topic is required.
    Your "most comprehensive studies" conclude that they are not large enough, and more research is required… pretty comprehensive indeed.

    @ 29:35 you are talking about cherry-picking.
    Who is the cherry-picker on this whole matter? All the hard scientific data that you just don't (or won't) see.

    @ 30:39 "So many nutrient deficiencies, that you are going to develop, if you stop eating animal products… including zinc".
    Conclusions concerning "zinc deficiency in vegetarian/vegan diet" again from the American Journal of Clinical Nutrition can be found here:
    Vegetarians/vegans can easily reach more than the daily recommended amount of zinc with just the smallest amount of effort, so don't go there, Mr. Cordain… you are creating an issue, where there is none.

    @ 35:23 you mention, that "B6… Vitamin B6 is another one"…
    By saying that, do you mean, that vegetarians/vegans will lack or be deficient in Vitamin B6?
    Where do you get that from?
    Again, don't go around making things up.
    Seeds, nuts, brown rice, whole grains, fruits and vegetables contain plenty of vitamin B6.

    @44:04 "Butter would be OK…"

    This is getting weird… I'll stop here.

    Smart fellow. This is not weird science folks, it is a simple truth. Low crab high protein, stay moderately active with bursts of high intensity.  Add it up, be healthier for longer.  lower disease risk.  Feel better, have more energy, actually, don't listen to this at all, you will sold be extinct anyway.
