LOREN CORDAIN, Ph.D., is one of the top global researchers in the area of evolutionary medicine. Generally acknowledged as the world's leading expert on the Paleolithic diet, he is a professor in the Health and Exercise Science Department at Colorado State University. Dr. Cordain and his research have been featured on Dateline NBC and in the New York Times, the Wall Street Journal, and other media. He is the author of The Paleo Diet and The Paleo Diet Cookbook, among other books, and makes regular media and speaking appearances worldwide.
I wrote a book called The Paleo Solution which went on to become a New York Times Bestseller. This book incorporates the latest, cutting edge research from genetics, biochemistry and anthropology to help you look, feel and perform your best. I am a research biochemist who traded in his lab coat and pocket protector for a whistle and a stopwatch to become one of the most sought after strength and conditioning coaches in the world. With my unique perspective as both scientist and coach you will learn how simple nutrition, exercise and lifestyle changes can radically change your appearance and health for the better.
The Paleo diet has been associated with many health benefits from better blood sugar levels to reduced inflammation. Considered one of the best diet plans for weight loss because it’s high in protein and fat and emphasizes nutrient-rich foods, it may also increase satiety and help correct nutrient deficiencies. Still, the diet has remained the subject of much controversy in recent years.

Vitamin D is the one supplement that would be paleo. At least it would be for those of us that don't live outside year round. You can have your D level measured. The low RDAs only prevent definable deficiences, not problems that take a long time to develop. Michael Holick, MD is a leading writer on this subject. This is a 10 page PDF: Vitamin D: importance in the prevention of cancers, type 1 diabetes, heart disease, and osteoporosis and its companion Sunlight and vitamin D for bone health and prevention of autoimmune diseases, cancers, and cardiovascular disease [change PDF to 100% to read]. Or if you prefer, there is an hour video on YouTube.
Interest and participation in the event continued to grow, and in 2010, the qualification was adjusted to include hosting multiple Sectionals, a series of events open to all athletes in order to qualify for the one of the 17 Regionals.[8] The 17 regions had Canada and the United States divided into 12 regions, with the remaining regions roughly corresponding the five other populated continents. The attendance at the Games also outgrew the ranch in Aromas and moved the Home Depot Center (later called the StubHub Center) in Carson, California.[9] The Games also expanded the Team Division to groups of six athletes and added a Masters Division for individual men and women 55-years-old and up.
You start to talk a language nobody understands – talking to a CrossFitter is like talking to somebody in a foreign language. CrossFit people oftentimes forget that nobody outside of CF understands what half the stuff they say means, so they shout out achievements or accomplishments and explain how quickly they did specific exercises…but they don’t realize nobody really cares!

Meetup has a growing number of paleo groups, now numbering in the dozens. Each has a local message board. They have a map of Paleo Diet Meetups around the world. Initially I tried listing them all here. The number grew and Meetup wasn't letting me find groups in newest order, except for my zip code. You now have to go there to find the one nearest you.
Catching Fire: How Cooking Made Us Human by Richard Wrangham. This book argues that the ease of digestion and the added nutritional value available in cooked food was the key behind the explosion of human intelligence. (Cooking gelatinizes starch, denatures protein, and softens all foods, permitting more complete digestion and energy extraction. As a result, the food processing apparatus shrinks, freeing energy to support a larger brain.) He then suggests that cooking led to what eventually became marriage and the sexual division of labor. The two most helpful reviews at Amazon get into great detail. The reviews average to 4+ stars.
Additionally, the Paleo diet puts a heavy emphasis on meat products. For this reason, the Paleo diet may not be suitable for everyone, and you’re unlikely to find a Paleo diet vegetarian or vegan modification out there. While meat in moderation is perfectly healthy, excessive meat consumption may not be. A high intake of red meat, for example, has been linked to an increased risk of mortality and colorectal cancer.

This list is going to be a little longer than the last. You cut out all sugar (both real and all substitutes whether natural or artificial, like honey, maple syrup, Splenda, etc.). No grains, legumes (including all forms of soy), dairy, or alcohol. You’re also told to avoid additives like MSG and carrageenan, although that should happen naturally if you’re sticking to whole foods.
For the 2019 CrossFit Games season, there will be 15 events taking place that are being called Sanctionals. These are sanctioned CrossFit competitions that are taking place in multiple countries across the globe. In the 2019 CrossFit Games Rulebook, CrossFit, Inc. states that the Santional events are not connected to the CrossFit Games, although, the male, female, and teams that win the elite division will receive an invite to the Games.
I recognize these drawbacks. But I still kick off the first month of each year by waving goodbye to alcohol, sugar, and yes, the aforementioned healthy food groups. While I've kept the majority of the weight off, I'm still guilty of putting on those extra 4 to 5 pounds throughout the year. But while that would've caused me anxiety before, I'm now okay with it. I enjoy some frozen drinks by the pool during my summer vacation and loosen the reigns a bit during the holidays. Come January 1st, my body desperately wants a break from the late-night holiday parties that cram my calendar from Thanksgiving until New Year's Eve, which is why I do another round of the Whole30. Starting the new year this way helps to reset the habits that I tend to lose track of towards the end of year (moderation and meal-prepping) and it reminds me how good my body feels when I'm treating it right.
According to Adrienne Rose Johnson, the idea that the primitive diet was superior to current dietary habits dates back to the 1890s with such writers as Dr. Emmet Densmore and Dr. John Harvey Kellogg. Densmore proclaimed that "bread is the staff of death", while Kellogg supported a diet of starchy and grain-based foods.[11] The idea of a Paleolithic diet can be traced to a 1975 book by gastroenterologist Walter Voegtlin,[7]:41 which in 1985 was further developed by Stanley Boyd Eaton and Melvin Konner, and popularized by Loren Cordain in his 2002 book The Paleo Diet.[8] The terms caveman diet and stone-age diet are also used,[12] as is Paleo Diet, trademarked by Cordain.[13]
Another 2014 study in the European Journal of Clinical Nutrition compared the effects of the Paleo plan to those of a standard low-fat diet on 70 obese, postmenopausal women. After six months, the Paleo group lost 14 pounds on average, while the other group lost nearly 6 pounds. After a year, the Paleo group had lost 19 pounds on average, and the low-fat dieters had dropped 10 pounds. A year later, both groups had regained some weight: The Paleo group was still down 10 pounds, while the low-fat group had dropped an average of more than 6 pounds.
Paul Burke's Neo-Dieter's Handbook: When We Lost Our Nutritional Roots; Where to Find These Foods Today by Paul Burke M. Ed. The book focuses on nutrition, the right nutrition to enhance health, exercise, weight training, and fitness. The diet consists of lean protein, vegetables, nuts, and fruit. He is opposed to grains. He wants you to stay away from grain-fed meat. The single review at Amazon.com gives the book 5 stars. Published August 21, 2009.
We have been lied to all our lives and told to eat plenty of whole grains and low fat. Grains have been genetically modified for so long and its effects on the human body have never been tested. Following the Paleo Diet principles have changed my life and helped me lose 37 pounds effortlessly. My health has vastly improved and I no longer have uncontrollable junk food cravings. I didn't know the cravings could be stopped, I just assumed I had no will power. My Doctor recommended this diet and I can't thank him enough! If you follow this way of living you will never regret it so buy this book and improve you health now!
The Dietitian's Guide to Eating Bugs by Daniel Calder is a comprehensive guide to the nutritional content of insects. He believes insect breeding and consumption are important elements sustainable living, particularly when it comes to complementing foraged plant material with meat products. Numerous insects contain nutrients similar to those found in more conventional livestock, except the feed to conversion ratio is much higher and they're much cheaper to breed. You can find the book at scribd. Also available in e-book format for $35.
Primal Blueprint Quick and Easy Meals: Delicious, Primal-approved meals you can make in under 30 minutes by Mark Sisson and Jennifer Meier. Every recipe is accompanied by an ingredient list, a nutrient list, clearly written instructions, and a picture of the ingredients and a picture of the finished product. Note that this is a primal book and many recipes include dairy. Published March 25, 2011.

However, placing certain food groups on your "do not eat" list does have the potential work against you. "When a person sees the foods as 'off limits,' and consuming them is somehow breaking a rule and therefore sees themselves as a 'bad person,' mental damage is what is going to ensue long term versus the 30-day health benefits that you will receive," Smith cautions.
Another downside: If you have had chronic health issues (especially gut related), you may find that reintroduction actually teaches you that you're sensitive to most foods. It turns out peanut butter, gluten, and most dairy are now off limits. That rots!! But I'll live. I feel so, so much better without them, as I learned. And wouldn't you rather know why you feel crappy all the time?
This does require effort. Grocery shopping, meal planning, dining out, explaining the program to friends and family, and dealing with stress will all prove challenging at some point during your program. We’ve given you a huge number of tools, advice, and resources, but take responsibility for your own plan. Improved health, fitness, and quality of life doesn’t happen automatically just because you’re now taking a pass on bread.
Get takeout flavor without the mystery additives: This Whole30 recipe recreates a comfort food classic with clean ingredients like fresh ginger, steak, and broccoli. Stay more Bulletproof and use grass-fed beef, arrowroot starch, coconut aminos, and coconut oil to cook. Plus, avoid enjoying black pepper and garlic too often, and consider steaming broccoli instead of stir frying.
The CrossFit Games are the world’s premier test to find the Fittest on Earth™. They are world-renowned as a grueling test for the toughest athletes and a thrilling experience for spectators. Since its inception in 2007, the CrossFit Games have become “one of the fastest growing sports in America,” according to Forbes. The Games season is broken up into three stages. The first stage is the Open, the largest participatory sporting competition in the world. After the Open, top athletes from each of the 18 worldwide regions qualify for the second stage of competition—Regionals. Following Regionals, the top 40 men, 40 women and 40 teams move on to the final stage of competition: the CrossFit Games. The Games present the playing field where the fittest athletes are given a chance to distinguish themselves through consistently exceptional performances across broad time and modal domains. At the end of the competition, the Fittest on Earth are crowned™. To learn more, visit Games.CrossFit.com or Facebook.com/CrossFitGames.
Jan Engvald has studied food and health thoroughly in the literature. In Unexpected facts on... food he shows that today's health advice (more or less unchanged for more than 30 years) is a direct cause to the increase in national diseases like coronary heart disease, stroke, cancer, obesity, adult-onset diabetes, allergy, eye diseases, etc. His findings are low-carb and high-fat, close to paleo, though he allows high fat dairy.

The first week was the hardest. I quickly learned that meal prep was essential to survive this program. Since everything you’re eating isn’t processed, there’s a lot of planning that goes into being able to have an easy week. If I prepped on Sunday nights for the whole week by filling my fridge with things I could easily eat, and doing things like pre-slicing veggies for those hunger emergencies, I did great.
is something you have to experience to truly understand and appreciate. CFHP is a fitness community of committed and focused individuals who are determined, dedicated and constantly setting and achieving new goals. Our brand new state of the art facility has no fancy equipment or machinery; just the basic tools of a true training program that delivers proven, measurable results.
All involve eating whole foods (as opposed to packaged and processed) and filling your plate with quality sources of protein, healthy fats, complex carbohydrates, and vitamin-, mineral-, and fiber-rich vegetables. (Again, we’re talking about the ones that fall somewhere on the healthy spectrum, not unhealthy fad diets like, ahem, the Grapefruit Diet.)
Annie Thorisdottir will become only the third athlete in history to reach 10 individual CrossFit Games appearances, joining Ben Smith and Becca Voigt. The current streak is 10 consecutive individual appearances held by Ben Smith. He had surgery earlier this year and still has a chance to qualify through a Sanctional. Camille Leblanc-Bazinet holds the second longest streak at nine and has the opportunity to tie Smith if she wins a Sanctional.
For example, although white potatoes were recorded as being available during the Paleolithic era, they are usually avoided on the Paleo diet because of their high glycemic index. Processed foods are also technically off limits due to an emphasis on fresh foods, but some Paleo diets allow frozen fruits and vegetables because the freezing process preserves most nutrients.

After the Internet fitness community began talking about an Ohio State University study that described relatively high injury rates among CrossFitters, the Russes mobilized. They had Glassman's father, Jeffrey Glassman (now "chief scientist" at CrossFit), write a comprehensive rebuttal to the study for the CrossFit website. Berger called each and every research subject who had been reported as injured, to conclude that none actually were hurt, and then added an entire stammering Q&A with one of the paper's authors, kinesiology professor Steven Devor. Here's the kicker: The actual subject of the study was the great improvements in fitness the researchers found in CrossFit athletes. Aside from a handful of sentences, it was all positive.
Peel/slice/dice all vegetables and store them in food storage containers in the refrigerator. Carrots, peppers, and potatoes should be stored in water to keep them from drying out and browning. Brussels sprouts should be stored in a dry container. This will drastically cut down on meal prep time each evening and will allow you to have fresh veggies on hand if you need a quick snack between meals.
Sex With Your Pants On (SWYPO) is a term used to describe the idea of recreating treats such as pancakes, brownies, or pizza with Whole30 ingredients, and is strongly cautioned against. The Hartwigs feel that if you’re trying to recreate a pizza made out of cauliflower crust in order to scratch a craving itch, then you’re kind of missing the point. To quote the Whole30 website, “You can tell yourself it’s okay, it’s still pretty good, you’re totally satisfied … but that’s kind of a lie. Because you know exactly how good pants-less sex feels.”
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.
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.

In the Rulebook CrossFit, Inc. writes,“Should the winner of a Sanctionals competition qualify for or receive an invitation to the Games by another means, the second-place athlete/ team from that Sanctionals competition will receive the invitation to compete at the Games. This backfill process will continue if the second-place athlete/team has already qualified, received an invitation, and so on.”
The New Evolution Diet: What Our Paleolithic Ancestors Can Teach Us about Weight Loss, Fitness, and Aging by Arthur De Vany. Art is the grandfather of the "Paleo Lifestyle" movement. The plan is built on three principles: (1) eat three meals a day made up of nonstarchy vegetables, fruits, and lean proteins; (2) skip meals occasionally to promote a low fasting blood insulin level; and (3) exercise less, not more, in shorter, high-intensity bursts. Note that the book is anti-fat. All oils are to be avoided, though canola is considered okay for higher temperatures. Egg yolks are to be skipped now and then. Published December 21, 2010.
The idea is that these are the foods that our bodies were designed to eat while many of the heavily processed modern foods that fill our diets today contribute to chronic disease and health problems. Proponents of the diet suggest that a well-planned Paleo diet could lead to improvements in many aspects of health, such as enhanced weight loss and reduced inflammation.
Re: “Too old masters’ age group”… I have zero insight as to whether or not this will happen, but I’m a betting man & I’m putting my money on yes. If CrossFit lasts, which I think it will, I believe they’ll continue to evolve as the sport grows in size and age. It’ll come down to how many “too old” athletes end up being serious competitors. You’ll lead the way.

Two years ago, I dropped 30 pounds (and kept it off) by doing the Whole30 and continuing to eat well in the months that followed. During the 30 days on the program, I lost 11 pounds. And for me, completing it helped me form healthy habits (like reading labels and not smothering everything in cheese), taught me how to cook an arsenal of healthy recipes I actually enjoyed eating and most importantly (and the reason why I do it every January), showed me how incredible my body feels when I'm not pumping it full of sugar and alcohol. These lessons stuck with me well past the 30 days, allowing me to drop an additional 19 pounds by April of that year and finally reach my goal weight.

By the end of my first Whole30, I had an entire document full of recipes I still wanted to try, which motivated me to keep going. Yes, you can stay compliant by eating steamed chicken and lettuce every day, but why would you do that to yourself? "Find foods that are easy to make and that you enjoy eating," Cohn says. "If you eat foods that you don’t like just to follow the diet, you are not going to continue to eat those foods once you are done with the 30 days." Pro tip: Google the Whole30 version of your favorite meal, there's probably a recipe out there for it. (Unless that meal is cake.) This really helped reignite my love for cooking and encouraged me to continue preparing my own meals, instead of relying on Seamless delivery.


The first thing you should make from this book? Red Curry Roasted Cauliflower (pg. 242). We've made it FIVE TIMES since we got the book. Super easy and so delicious. If you follow us @gneissspice on instagram, you’ll see dozens of posts of the meals I made from this book. I highly recommend this book, especially if you are debating a Whole30. Nothing is worse than trying to stick to the strict rules, and then have no idea what to eat for dinner. My only complaint about the book would be no mention of portion sizes. I had to head over to their website to find suggestions (they have a cool graphic for this, not sure why they didn’t include it in the book).

In terms of food, I kicked up my creativity up a notch in the kitchen. I tried experimenting with recipes that were a little more complex than my usual, like making pesto out of cashews and avocados and serving it over a plate of zoodles. I made blueberry energy bites in my food processor to snack on during a movie marathon and grab for a quick breakfast. I also tried new snacks, like bottled tomatillo jalapeno soup from ZÜPA NOMA and chia pudding from Daily Harvest to mix things up.
Optimal Diet is a dietary model of human nutrition devised and implemented by Dr. Jan Kwasniewski. Lots of fat and low in carbs. Lots and lots of articles collected from various places. He has an out-of-print book: Optimal Nutrition. The book is explained at the Australian Homo Optimus Association website. A thorough analysis is the first post here: Dr. Kwasniewski's Optimal Diet: Sanity, Clarity, Facts.
The Paleo diet is the healthiest way you can eat because it is the ONLY nutritional approach that works with your genetics to help you stay lean, strong and energetic! Research in biology, biochemistry, Ophthalmology, Dermatology and many other disciplines indicate it is our modern diet, full of refined foods, trans fats and sugar, that is at the root of degenerative diseases such as obesity, cancer, diabetes, heart disease, Parkinson’s, Alzheimer’s, depression and infertility. – Robb Wolf

But in the Times article--headlined "Getting Fit, Even If It Kills You"--Glassman used the kind of tough-guy talk he used to shout at CrossFitters during their WODs. "It can kill you...I've always been completely honest about that," he said. "If you find the notion of falling off the rings and breaking your neck so foreign to you, then we don't want you in our ranks." Punctuating his blunt attitude, he had led his October journal article with a cartoon of a new clown, Uncle Rhabdo, who stands exhausted before a dialysis machine, his kidneys splattered in a pool of blood. The Times mentioned that, too.
He was in Seattle on business. The calendar that morning said Thursday, but Glassman's gut said the mall, and the day had meandered from there. He had bought himself and his pilot new blaze-orange parkas at Mountain Hardwear, and taken his girlfriend to Tiffany's to buy her a diamond pendant for her birthday. At first, the Tiffany's staff had eyed him suspiciously: With his faded jeans, his parka, and the backward red baseball cap over his scraggly wisps of gray hair, the 56-year-old looked as if he had wandered in from a tailgate party somewhere or might whip out a hammer for a smash-and-grab. But then, it turned out the saleswoman was one of them. Her sinewy body should have been a giveaway. "Greg Glassman!" she said, looking at his credit card. "My husband was with you last night!"
