The Stone Age Diet: Based on in-depth studies of human ecology and the diet of man by Walter L. Voegtlin. This was self-published back in 1975. Only a couple hundred copies were printed and distributed to friends and relatives. No one knew the book existed until some years later. In no way is he the father of the paleo diet. It is impossible to purchase. Apparently his descendents are planning a reprint, though the book is poorly written and not based upon factual anthropological information that even was available then. We have put up his Functional and Structural Comparison of Man's Digestive Tract with that of a Dog and Sheep. And a PDF can be found here.
CrossFit gyms use equipment from multiple disciplines, including barbells, dumbbells, gymnastics rings, pull-up bars, jump ropes, kettlebells, medicine balls, plyo boxes,[23] resistance bands, rowing machines, and various mats. CrossFit is focused on "constantly varied, high-intensity, functional movement,"[24] drawing on categories and exercises such as calisthenics,[25] Olympic-style weightlifting, powerlifting, Strongman-type events, plyometrics, body weight exercises, indoor rowing, aerobic exercise, running, and swimming.[26]

Oils are trickier. Loren Cordain, Ph.D., founder of The Paleo Diet Movement, breaks down which oils are healthy on the paleo diet: olive, walnut, flaxseed, macadamia, avocado and coconut oils are all allowed because they were gathered directly from the plant. While our hunter-gatherer ancestors probably did not consume flaxseed oil, it is allowed because of its content of high alpha-linolenic acid (ALA), a type of heart-healthy, anti-inflammatory omega-3 fatty acid.
So you can imagine that their stance on cheating in the program is very stringent. If you cheat, you’re supposed to start again at day one with no exceptions. As an intense perfectionist in life, this scared me more than any other rule or dietary restriction. And to be fair, I think that any dietary change is hard. Maybe it’s not like quitting heroin, but it’s also not like a spa massage. Did I mention that I also don’t like when people tell me what to do? As a really small child, I stabbed myself in the eye with a fork because my mom told me not to. Yeah … tough love isn’t my love language. Life is complicated.

This is not hard. Don’t you dare tell us this is hard. Fighting cancer is hard. Birthing a baby is hard. Losing a parent is hard. Drinking your coffee black. Is. Not. Hard. You’ve done harder things than this, and you have no excuse not to complete the program as written. It’s only thirty days, and it’s for the most important health cause on earth—the only physical body you will ever have in this lifetime.
This is a complete list of foods not allowed on the paleo diet. It’s a sad day when you first have to say goodbye to these foods but, once you start, it’s much easier and you find there are even better paleo substitutes for these foods. The first few weeks might be tough, but if you stick with it over time, it’ll be worth it. We promise. Here’s the ultimate list of foods not allowed on the paleo diet.

For most people the fact the Paleo diet delivers the best results is all they need. Improved blood lipids, weight loss, and reduced pain from autoimmunity is proof enough.  Many people however are not satisfied with blindly following any recommendations, be they nutrition or exercise related. Some folks like to know WHY they are doing something. Fortunately, the Paleo diet has stood not only the test of time, but also the rigors of scientific scrutiny.


The scoring for this workout includes a tiebreak. At the end of each set of double-unders, time should bemarked. When you submit your nal result, your scorewill be the number of reps completed. There will beanother eld where you will enter the elapsed time atwhich you completed your last set of double-unders. In the case where two athletes have the same score (total number of reps), the athlete with the lower tiebreak will be ranked higher.
The China Study is frequently cited when criticizing the Paleo Diet – focusing on a vegetarian diet and consuming rice is healthier than the Paleo Diet. I respectfully disagree with that nutritional philosophy and strongly disagree with the conclusions drawn from that book [7], and will leave you to make your own conclusions based on your own self-experimentation.
Go heavy on the veggies. For example, at lunch and dinner, make them three quarters of your plate, with one quarter occupied by meat—instead of the other way around. If you’re okay with just Paleo-ish, you could even replace a few meat dishes each week with a plant-based meal that incorporates legumes or Greek yogurt (cue the fainting of Paleo purists).
Note: If you don’t have a grill, you can bake the chicken in the oven. Turn the oven to Broil (or 500°F), and place the raw chicken in a baking dish. Sear the chicken in the oven for 5 minutes. Reduce the oven temperature to 350°F. Brush the chicken with the curry sauce and finish cooking in the oven for 10 to 15 minutes (depending on thickness), until the internal temperature reaches 160°F.
If you're interested in the paleo plan but don't think you want to be so strict, you don't have to be all-or-nothing with your approach. Consider adopting some eating patterns from paleo and skipping the ones that don't work for you. For example, try just eating more fruits and vegetables and cutting down on added sugars. If you feel unsure about grains or dairy, talk to your doctor or a registered dietitian to determine what's best for your body.
To make the curry sauce, melt the cooking fat in a saucepan over medium heat and swirl to coat the bottom of the pan. When the fat is hot, add the onion and cook, stirring, until translucent, 2 to 3 minutes. Add the garlic and stir until it becomes aromatic, about 30 seconds. Add the curry powder and stir for 15 to 20 seconds, taking care that the garlic and curry powder don’t burn. Add the tomatoes and simmer until thickened, about 5 minutes. Transfer the contents of the pan to a food processor or blender and puree until smooth. Pour into a mixing bowl and let cool. Mix in the coconut cream, salt, and pepper.
CrossFit, Inc. founder Greg Glassman overhauled the format for the 2019 games, replacing the Regionals with CrossFit-sanctioned international qualifying events.[18] As part of the changes, the 2019 games athletes qualify through being the top individual and team finishers from the sanctioned events, the top athlete from each country in the CrossFit Open, the top 20 overall finishers in the CrossFit Open, and four at-large athletes as chosen by CrossFit, Inc. Teams also no longer need to be created from one CrossFit-affiliated gym and can be formed from any four competitors.[19]

Alcohol is a no-no if you are strict paleo. Beer is made from grains, and liquor also contains traces of gluten. But, good news for cider-lovers: most hard ciders are gluten-free, so they are allowed. Check the label to be sure. Red wine is more accepted in the paleo community because it contains the antioxidant resveratrol, but sorry chardonnay lovers, white wine is technically not allowed.

Nourishing Traditions: The Cookbook that Challenges Politically Correct Nutrition and the Diet Dictocrat by Mary G. Enig, Ph.D. and Sally Fallon. The premise is the culinary traditions of our ancestors, and the food choices and preparation techniques of healthy nonindustrialized peoples, should serve as the model for contemporary eating habits. However, they push whole grains and dairy, which aren't Paleolithic.

We also talked about our meals, our struggles, and the results we were seeing from Whole30. Mentally, I felt more clear-headed and emotionally stable. I slept deeper and remembered more of my dreams, something that tends to never happen. (In one dream, I accidentally ate a slice of pizza and cried about it because if you break your Whole30 diet, you're supposed to start again from Day 1.)

I cannot possibly put enough emphasis on this simple fact—the next 30 days will change your life. It will change the way you think about food. It will change your tastes. It will change your habits and your cravings. It will restore a healthy emotional relationship with food, and with your body. It has the potential to change the way you eat for the rest of your life. I know this because I did it, and millions of people have done it since, and it changed my life (and their lives) in a dramatic and permanent fashion.

Fattening cattle with corn changes the lipid balance and is clearly not the natural diet for a grass eating cow. In Simple change in cattle diets could cut E. coli infection researchers have found that when cattle were fed hay or grass for just five days before slaughter, much less E. Coli cells were present in the animal's feces and virtually all surviving E. coli bacteria were not acid-resistant and were killed by human stomach acid.
So what does the science say about the paleo diet? Some research suggests that the health claims hold truth. A review analyzed four randomized, controlled trials with 159 participants, and researchers found that the paleo diet led to more short-term improvements in some risk factors for chronic disease (including waist circumference and fasting blood sugar) compared with other control diets. (4)

Paleo critics point out that not all grains are created equal—whole grains do not spike your blood sugar as much as refined grains. Even so, paleo dieters still steer clear of grains because they contain different compounds and proteins like gluten, lectins and phytates, which they claim cause inflammation in the body and block other nutrients from being absorbed. Paleo critics say these compounds are not a problem unless you have an allergy or sensitivity.
Sweden's Staffan Lindeberg has a home page Paleolithic Diet in Medical Nutrition [archive.org]. A recent study of Staffan's has A Paleolithic diet improving glucose tolerance more than a Mediterranean-like diet in individuals with ischemic heart disease. Also see his first web page, an overview of his Kitava study: On the Benefits of Ancient Diets. Now he has a book Food and Western Disease: Health and nutrition from an evolutionary perspective. Here's a book review: Easy to Read, Informative, Packed with Footnotes on Studies.
Evolution of the Human Diet: The Known, the Unknown, and the Unknowable by Peter S. Ungar. Diet is key to understanding the ecology and evolution of our distant ancestors and their kin, the early hominins. A study of the range of foods eaten by our progenitors underscores just how unhealthy many of our diets are today. This volume brings together authorities from disparate fields to offer new insights into the diets of our ancestors. Paleontologists, archaeologists, primatologists, nutritionists and other researchers all contribute pieces to the puzzle. The book has four sections: Reconstructed diets based on hominin fossils--tooth size, shape, structure, wear, and chemistry, mandibular biomechanics. Archaeological evidence of subsistence--stone tools and modified bones. Models of early hominin diets based on the diets of living primates--both human and non-human, paleoecology, and energetics. Nutritional analyses and their implications for evolutionary medicine.
2019 is already shaping up to be a phenomenal Games season, even in this transitional year. From Dubai to Miami to Australia, the Sanctionals to-date have been outstanding. Two weeks ago the competitive CrossFit season expanded into Cape Town, South Africa. And the competition will soon migrate to London. That’s the CrossFit affiliate community creating something valuable that no amount of money or central planning at CrossFit, Inc. could have pulled off in an authentic way. The Sanctionals season will continue to develop and reflect the extraordinary diversity and worldwide growth of the CrossFit affiliate community.
The paleo diet (also nicknamed the caveman diet, primal diet, Stone Age diet, and hunter-gatherer diet) is hugely popular these days, and goes by one simple question: What would a caveman eat? Here, we explain what the paleo diet involves, its pros and cons, and, ultimately, what a modern person needs to know to decide whether or not to take the paleo diet plunge.
A better idea is to reincorporate small amounts of non-Whole30 foods one at a time, waiting a few days before adding something else back in. For instance, after day 30, continue to follow the diet, but have yogurt for breakfast and add some cheese to your salad. Do this for a few days and see if any symptoms pop up. If they do, you know that dairy is problematic for you. Then, try the same thing with another food group, like gluten-free grains. Reintroducing gluten-free and gluten-containing grains separately can help you determine whether you have a gluten sensitivity.

Excluding foods. The exclusion of entire categories of commonly eaten foods like whole grains and dairy requires frequent label reading in the supermarket and in restaurants. It may also increase the risk of deficiencies such as calcium, vitamin D, and B vitamins, if these nutrients are not consistently eaten from the allowed foods or a vitamin supplement. For example, there are some nondairy calcium-rich foods that are absorbed well by the body such as collard and turnip greens or canned bone-in sardines and salmon, but you would have to eat five or more servings of these greens and fish bones daily to meet recommended calcium needs. (Note that some greens like spinach that are touted to be calcium-rich also contain oxalates and phytates that bind to calcium so very little is actually absorbed.) One small, short-term intervention study of healthy participants showed a 53% decrease from baseline in calcium intake after following a Paleo diet for three weeks. [8] Furthermore, the exclusion of whole grains can result in reduced consumption of beneficial nutrients such as fiber and thus may increase one’s risk for diabetes and heart disease.

You never, ever, ever have to eat anything you don’t want to eat. You’re all big boys and girls. Toughen up. Learn to say no, or make your mom proud and say, “No, thank you.” Learn to stick up for yourself. Just because it’s your sister’s birthday, or your best friend’s wedding, or your company picnic does not mean you have to eat anything. It’s always a choice, and we would hope that you stopped succumbing to peer pressure in 7th grade.

Why so strict? According to the diet's founders, Melissa and Dallas Hartwig, these are the foods that are most likely to cause inflammation and gut damage. They're also the foods that the founders say destabilize blood sugar levels and lead to cravings. But it's hard to say whether that's true for everyone. In general, limiting sugar and alcohol is always a good idea. But dairy, grains, and legumes? They don't trigger an inflammatory response in everyone, Haas says.


Update: So I just finished Day 23 of my Whole30 Journey and I feel good, aside from the fact that I caught a cold. Weighing myself today, I discovered that I lost 19.5 pounds so far! I measured myself and immediately noted that I lost 19 inches over all (I measure my chest, both arms, both legs, waist, and hips). I think when I am done with my first round, I'll take a day off then start a second round. I just feel that great overall.
Following seven years in Carson, the Games moved to the Alliant Energy Center in Madison, Wisconsin, in 2017.[16] The next year, the qualifying Regionals were once again realigned due to increased competitiveness and popularity outside of Canada and the US.[17] In 2018, there were nine Regionals hosted among 18 redefined regions with Europe increasing to three regions, Central America split from South America, while eliminating the Northern and Southern California regions.
Overall, the diet is high in protein, moderate in fat (mainly from unsaturated fats), low-moderate in carbohydrate (specifically restricting high glycemic index carbohydrates), high in fiber, and low in sodium and refined sugars. [2] The monounsaturated and polyunsaturated fats (including the omega-3 fats EPA and DHA) come from marine fish, avocado, olive oil, and nuts and seeds.
I thought Week 1 was hell on earth, but boy was I wrong. Week 4 tested my patience and willpower like never before. Eating Whole30 staples like avocado and eggs became a chore. I choked down so many hard-boiled eggs during my last week, but all I could think about was how I wished they were freshly baked bagels—or even just a bowl of plain white rice. Anything but eggs.

With a very simple shift we not only remove the foods that are at odds with our health (grains, legumes, and dairy) but we also increase our intake of vitamins, minerals, and antioxidants. Here is a great paper from Professor Loren Cordain exploring how to build a modern Paleo diet: The nutritional characteristics of a contemporary diet based upon Paleolithic food groups. This paper also offers significant insight as to the amounts and ratios of protein, carbohydrate and fat in the ancestral diet.
If you've been reading about the latest diet trends, then you've definitely heard about Whole30. When you have to say sayonara to pasta, alcohol, dessert, and dairy for a month, it can reveal things about your diet you probably want to change. From uncovering food sensitivities to combating sugar addictions, the Whole30 diet can transform the way you eat—promoting a cleaner eating approach.
In one example, CrossFit, Inc.'s Twitter account posted a doctored illustration of a Coke advertisement, with "Open Happiness" replaced by "Open Diabetes". The image was paired with a quote from CrossFit CEO Greg Glassman that read "Make sure you pour out some for your dead homies."[85][86] Controversy followed after singer Nick Jonas responded to the tweet, calling CrossFit, Inc.'s comments "ignorant".[87] The company defended its tweet, stating that "Compelling statistical evidence supports CrossFit, Inc.'s campaign to prevent diabetes by raising awareness about its causes."[88] When ABC News asked Greg Glassman to comment on the exchange, he replied "Fuck Nick Jonas. This is about the scourge of Type 2 Diabetes and its underlying causes. His sponsor, Coca-Cola, is a significant contributor to the diabetes epidemic both with product and 'marketing' spend."[1][88]
