    What Are the Risks Linked to High Protein, Low-Carb Diets?
    High protein, low-carb diets can cause a number of health problems, including:

    Kidney failure. Consuming too much protein puts a strain on the kidneys, which can make a person susceptible to kidney disease.

    High cholesterol . It is well known that high protein diets (consisting of red meat, whole dairy products, and other high fat foods) are linked to high cholesterol. Studies have linked high cholesterol levels to an increased risk of developing heart disease, stroke, and cancer.

    Osteoporosis and kidney stones. High protein diets have also been shown to cause people to excrete more calcium than normal through their urine. Over a prolonged period of time, this can increase a person's risk of osteoporosis and kidney stones.

    Cancer. One of the reasons high protein diets increase the risks of certain health problems is because of the avoidance of carbohydrate-containing foods and the vitamins, minerals, fiber, and antioxidants they contain. It is therefore important to obtain your protein from a diet rich in whole grains, fruits, and vegetables. Not only are your needs for protein being met, but you are also helping to reduce your risk of developing cancer.

    Unhealthy metabolic state (ketosis). Low-carb diets can cause your body to go into a dangerous metabolic state called ketosis since your body burns fat instead of glucose for energy. During ketosis, the body forms substances known as ketones, which can cause organs to fail and result in gout, kidney stones, or kidney failure. Ketones can also dull a person's appetite, cause nausea and bad breath. Ketosis can be prevented by eating at least 100 grams of carbohydrates a day.

      Regarding various comments on high-protein diets -- these seem to assume we're staying in hyper-lowcarb ketosis forever, but standard-issue primal diet is not really low-carb in the Atkins Induction sense.

      Same for the "cancer" bullet -- this all presupposes that we're avoiding fruit and vegetables. A standard primal diet doesn't -- quite the opposite really, we end up eating more veggies than the average person who's chowing down on pasta and bread.

      So I'd sum up by saying "possibly true, but not actually relevant to primal"
      "Trust me, you will soon enter a magical land full of delicious steakflowers, with butterbacons fluttering around over the extremely rompable grass and hillsides."

        Read Dr. Eades' book "Protein Power." He puts the scientific lie to every one of those claims.
        Primal eating in a nutshell: If you are hungry, eat Primal food until you are satisfied (not stuffed). Then stop. Wait until you're hungry again. Repeat.

          Big thing to remember -this is not a high protein diet, it is a high FAT diet.

          Without a good amount of fat, it doesn't work. I personally believe that proper fat content is a lot more important than veggies/fruits. You see it on the forum all the time, people are 1 week or 3 months primal, and they complain about it not working, not loosing fat, feeling ill. As soon as they post up their diet, more often than not it is pointed out that their fat intake is too low.
          - If it was cute and cuddly at some point, eat it. Ignore everything else. -

          - Food is first, and foremost, nothing more than fuel. -

          - The body is animal. The mind, however, is not. -

            The article is talking about a high-protein diet, which Primal is NOT. This is an adequate-protein diet

            Cholesterol values have not been shown to be linked to disease in the absence of a carb-based diet .

            Also, ketosis is not dangerous in the least. It is here, as in many other places, confused with keto-acidosis, which is exactly the same as confusing "adequate glucose levels" with "hyperglycemia". And it's just plain hilarious that they think that the 'appetite blunting' effect of ketones are a BAD thing

              I am a on the high protein low carb (mostly) version of the primal diet and I would say that pretty much all of the is false.

                I would stipulate that one can vary the amount of fat vs protein on the primal diet to myself and other lifters around here. While I do not shun fat protein is where my dietary focus lies.

                  The last point was either written by someone ignorant enough that they don't know the difference between ketosis and ketoacidosis, or manipulative enough to purposely mix them up to scare people away from low carb diets (I bet it's the latter).

                  Ketoacidosis is dangerous and can lead to organ failure, but also generally only happens in type 1 diabetics (diabetic ketoacidosis) or people who consume a lot of alcohol for a prolonged period of time (alcoholic ketoacidosis). Ketosis can cause bad breath or smelly urine, and some people just don't feel so great when they're in ketosis, but there is nothing at all dangerous about it.

                    Actually, dietary cholesterol intake has hardly any impact on blood cholesterol. This is old news. And saying high cholesterol causes an increased risk of heart disease is so oversimplified it is meaningless. There are multiple forms of cholesterol, each serving different functions. The truth is triglyceride levels correlate far better with the risk of vascular disease, and triglycerides levels ARE clearly linked to dietary carbohydrate intake.

                    One of the fundamental reasons for eating paleo/primal/caveman is to reduce cancer risk. The anthropological record is filled with reports of primitive hunter gatherer societies who eat only plants and animals and have negligible rates of cancer. It is only when they are assimilated into the broader society and start eating a conventional diet with the attendant increase in grain/carb consumption that the various forms of cancer emerge. Along with the other well documented "diseases of civilization" (heart disease, diabetes, arthritis, hypertension, autoimmune illness, and likely many more).

                    The best source of all those vitamins, minerals, and antioxidants are plants and animals. Breads, pastas, potatoes, rice are nutritionally poor.

                    The Inuit, Masai, and many other primitive societies eat a diet almost exclusively of meat, and spend virtually their entire life in ketosis. The enjoy tremendous health, don't become decrepit as they age, and could break us in two with their eyelashes. Prolonged ketosis was studied under controlled conditions in the 1930s (achieved by the subjects eating a diet of meat alone) with no adverse health consequences (on the contrary, several health benefits were seen). So it is absurd that 80 years later people are still being scared away from it.

                    While webMD is a good source for a lot of medical information, it is a terrible place for nutritional advice. Their advice above, if followed, will lead to progressive sickliness and untimely death.

                    To better understand why, read Good Calories, Bad Calories by Gary Taubes. Then go read the Primal Blueprint by Mark Sisson.

                      As post number 6 says, Mark never told anyone to overeat protein.

                      Let's take this one instead, as I don't think anyone touched on it yet.

                      The assertion seems to be that "carbohydrate-containing foods" are a source of "vitamins, minerals, fiber, and antioxidants".

                      First off, "carbohydrate-containing foods" is a nonsense. Almost all foods contain some. Secondly, some high-carb foods contain some vitamins and minerals. However, that glosses over the fact that many don't contain much at all - and have been responsible for some horrific deficiency diseases across the globe. It also hides the fact that fat-soluble vitamins are extremely important, and you're not going to get those from high-carb plant foods - in fact, you can't get vitamin A at all from plant foods (only it's precursors, which some individuals can convert and some can't). Thirdly, there's nothing in fruit, which is generally fairly high-carb that isn't in vegetables - and that includes "fiber" ... although the theory that one needs a lot of that is just that: a highly questionable theory.

                      Lastly, cancer? Are they serious?

                      Lights Out has some interesting commentary on the notion that a low-fat diet would guard against cancer. The authors, including a biochemist with three degrees from a prestigious university, asked someone at the Harvard School of Health what they had to say in response to the rate of cancer (and several other ailments) not having fallen despite people eating - as told - lower and lower fat diets. The individual in question replied "It was only an hypothesis". As they remark, not much of an apology, is it? Now, I think Lights Out was published ten years ago (?) Are people still asserting that a low-fat diet will protect against cancer when there's now even more evidence that it won't?

                      The authors of Lights Out consider there's quite a lot of evidence now pointing to the role of lack of sleep (and over-consumption of carbohydrates) in cancer. Interestingly, they say that the only animals apart from man that, in the normal way of things, suffer from cancer are our pets. Notice our pets have their sleep-patterns disrupted by us, and are subject to our light-pollution as they sleep. If you don't sleep enough, and you don't sleep in the dark, your hormones get screwed up and your immune system gets compromised.

                      In short, I think there's nothing to see here. it's just people repeating the same tired old mantras yet again. None of theses assertions really holds water, it's just a load of assumptions that people keep repeating - as if that would make them true.

                        Ate - past tense. Mostly, they don't any more.

                        Also, this was not just the people who now often refer to themselves as Inuit, but also the Yup'ik, Inupiat, and Inuvialuit*. IOW, all the Eskimo peoples.

                            Actually, I'll add something from my own food today. I put it in Fitday just to see.

                            So here's what I had:

                            1 teaspoon natural fermented cod liver oil
                            1 sausage,
                            2 eggs fried in butter
                            2 oz. blueberries

                            2 oz. biltong (African raw dried grass-fed beef)
                            1 tablespoon butter
                            2 raw tomatoes
                            1 oz. pecans


                            8 oz. Welsh hill lamb (fat and lean eaten)
                            10 spears asparagus with butter
                            1 cup coconut milk
                            1 cup chunks of fresh pineapple
                            1.5 oz. Manchego cheese

                            Ok, so not to blame what I happened to eat on Mark or anything. (He might not agree with all those food choices. And he'd probably have had a big salad for lunch - and so might I on another day.) I'm just giving it as a sample.

                            That's about 2, 500 calories and the proportions are about 73% fat, 19% protein, 9% carbs. So that's a low-carb diet. In fact, according to Fitday, there's only 59 g of carbs there (even though I happened to have two servings of fruit). So that's definitively low-carb (lower, in fact, than Mark's "maintenance" recommendation).

                            Now according to Fitday's nutrition calculator, I'm at or over the RDA on almost every nutrient listed. In some cases I've had twice the RDA or more. The only things I'm (a little) low on are calcium, magnesium, and Vitamin E.

                            If I'd happened to choose almonds instead of pecans I'd probably be over on the vitamin E. A load of bread and pasta isn't going to help on the calcium front. However, if I'd had seafood, some leafy green vegetables, or a little more cheese - as I might well have done - I might not have been under. As for Magnesium - everyone's low on that, and I take a supplement because of that.

                            On every over vitamin and mineral I'm better than the RDA.

                            So much for I need to eat high-carb or I'll be low on vitamins and minerals. The figures show otherwise.

                              Looks tasty, Lewis!

                              So, I'm really wondering what mythical "low carb diet" these types of articles and studies are referring to, where participants apparently don't eat any vegetables. I have a feeling it isn't a carnivorous diet either, but is actually some pop-Atkins frankenfood diet. Does anyone know?

                              In my house, we go through produce like it's going out of style. Today, I've already eaten a pear, 4 cups of spinach, 1/2 of a tomato, a bell pepper, 1/4 of an onion, half an avocado, a clove of garlic, and about 1" of ginger root, and I haven't even had dinner yet. Low carb does not mean low veggie!
