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.
"Every fad diet thinks it has discovered the root of all evil," says Dr. Ochner. But nutrients in legumes, whole grains, and dairy—all of which are forbidden on the paleo diet—can help to lower the risk of osteoporosis and cardiovascular disease, reduce blood pressure, and promote a healthy weight, he says. Cutting dairy, the primary source of calcium and vitamin D in modern diets, is especially worrisome for women who want to avoid osteoporosis.
"CrossFit is not a specialized fitness program, but a deliberate attempt to optimize physical competence in each of 10 recognized fitness domains," says founder Greg Glassman in the Foundations document. Those domains are cardiovascular and respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy.[33]
The CrossFit Games is an athletic competition sponsored by Crossfit Inc.[1] and Reebok.[2] The competition has been held every summer since 2007. Athletes at the Games compete in workouts that they learn about hours or days beforehand, consisting mostly of an assortment of standard aerobic, weightlifting, and gymnastics movements, as well as some additional surprise elements that are not part of the typical CrossFit regimen such as obstacle courses, ocean swimming, softball throwing, or ascending a pegboard.[3][4] The CrossFit Games stylizes their individual winners as the "Fittest on Earth".[5]
In December 2005, The New York Times ran a story about the budding CrossFit craze. The reporter interviewed some of the original CrossFitters and chronicled their fitness accomplishments, which were considerable. But the part of the article that grabbed the most attention was the opening anecdote: A first-time CrossFitter named Brian Anderson had experienced a true mess-you-up moment--he had ended up in the emergency room after his baptismal WOD. Repeated kettlebell swings had torn up his lower back to the point that he could barely stand. In intensive care, he was told he had rhabdomyolysis, a condition wherein muscle tissue breaks down to the point that it starts poisoning the kidneys. Rhabdomyolysis is rare as a result of athletics; ultramarathoners sometimes get it, but ER doctors are much more accustomed to finding it in cases of crushed limbs or massive third-degree burns. Anderson didn't need dialysis, but he spent six days on an IV drip in intensive care, followed by two months of physical therapy for his back.
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]
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.
A great question to ask is “Does the Paleo diet work?” Here we have a head to head comparison between the Paleo diet and Mediterranean diet in insulin resistant Type 2 Diabetics. The results? The Paleo diet group REVERSED the signs and symptoms of insulin resistant, Type 2 diabetes. The Mediterranean diet showed little if any improvements. It is worth noting that the Mediterranean diet is generally held up by our government as “the diet to emulate” despite better alternatives. You can find an abstract and the complete paper here.
Paleo Pals: Jimmy and the Carrot Rocket Ship by Sarah Fragoso. Piper, Phoenix and Parker are not ordinary children–they are super heroes that travel the land helping other children learn about living the healthiest, most exciting, most super lives possible. They are known as The Paleo Pals, and this is a story about how they help out Jimmy, a little boy who is not sure if eating paleo food is even one tiny bit exciting or super. Published February 7, 2012.
It’s easy to find more guidance online, but a book also makes a handy reference. "The Paleo Diet," for example, outlines basic Paleo principles and offers three “levels” that allow for different degrees of cheating – three “open meals” per week on the “entry level” plan, two on “maintenance” and just one on “maximal.” Depending on the level, you might also get “transitional” condiments (low-fat dressing and salsa) and drinks (coffee, beer or wine in moderation) to wash down the meat and plants. You can use the levels as you like. Start with the first and move gradually to the more restrictive – or just stay put. For more dramatic changes, head right to the third.
People looking for support and community – This is the appeal to CrossFit for me: every CrossFit gym has a really tight-knit community feel to it. You’re not just a membership payment to them; you’re a person that needs support. When Nerd Fitness gyms start popping up (don’t think it won’t happen!), I’ll be drawing a lot of inspiration from CF as to how members are so supportive and inclusive of each other.
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.
Workout 4A & 4B has an 11 min time cap. It is a chipper that begins with the athlete standing tall behind their measured handstand-pushup box. At the start of the ascending clock, the athlete will kick up to a locked out handstand before performing their repetitions. They will then move onto the pull-ups and complete 50 repetitions before moving to the toes to bar to complete another 50 repetitions, and lastly onto the wall-balls, complete 50 repetitions. Athletes may take as many sets, breaking up the work as needed, to complete the required number of repetitions throughout the workout.
“I think there are a lot of positives about it,” Holley says. “It cuts out a lot of processed foods just naturally, like processed grains or added sugar through soft drinks or juice.” And because the diet promotes eating anti-inflammatory foods — like fruits, vegetables, and unsaturated fats in nuts and certain oils — your health could benefit, Holley explains. Cutting out processed foods and sugar will also help lower your risk of certain diseases, like type 2 diabetes and certain cancers, she says. (6)

Sugar is almost always manufactured and should be avoided on the paleo diet. This means you’ll need to cut out the delicious but destructive sweets and sugars that are standard in the Standard American Diet. The rule of thumb here is: if it contains a ton of sugar, it’s probably not on the paleo diet friendly. That said, here’s a specific lists of sweets that are not on the paleo diet food list. You might want to take a moment to say goodbye to them before you start your paleo diet journey.
While founders Dallas Hartwig and Melissa Hartwig are adamant in their book and on their website that “you’ve done harder things than this, and you have no excuse not to complete the program as written,” the Whole30 is not for the lazy or noncommittal. Without careful planning, a strong support system and dogged dedication, a business lunch, flight delay or date night can throw you off and send you back to the start. By nature, diets that eliminate entire food groups are tough to follow. On the other hand, it’s only 30 days.
Origins and Evolution of Human Diet was an academic web site at the University of Arkansas devoted to discussion of evolution and the human diet. They had good articles on the conferences link. Here is one from the archives: Boyd Eaton's Evolution, Diet and Health which argues that current w-6 : w-3 imbalance together with absolute dietary DHA intake quite low in human evolutionary perspective may be relevant to the frequency of unipolar depression.
CrossFit, Inc. has also been criticized for having a "cavalier"[77] attitude towards rhabdomyolysis by promoting a character known as "Uncle Rhabdo" (a cartoon clown dying in a dramatic fashion—hooked up to a dialysis machine, with his kidneys and intestines falling on the floor).[73] In response to this criticism, Greg Glassman stated "We introduced (Uncle) Rhabdo because we're honest and believe that full disclosure of risk is the only ethical thing to do."[71]
Like the Paleo Diet, the Keto Diet is low in carbs. But the primary goal of the Keto Diet is to put your body into a state of ketosis, which is when your body uses fat instead of carbohydrates as its primary energy source. When your body enters ketosis, fat travels to the liver and makes an acid called ketones, which enter your bloodstream and are converted into energy.
One of the most interesting experiments comes after you finish Whole30 and slowly start adding foods back into your diet. You get to test how foods you stopped eating during the month affected you after you added them back in. The most shocking for me? Legumes make me feel bloated (they just do!). When I added gluten back, the next day I broke out in a rash. And now that I've curbed my "sugar dragon" (that's what they call sugar cravings on Whole30), I try to avoid sugar as much as humanly possible. In fact, December came after my Whole30 experience, so of course I indulged in a few glasses of wine at a holiday party, and BOOM — my skin broke out. Now I have a better idea of what to avoid altogether, and what to watch if I do decide to indulge.
"Loren Cordain's extensive research demonstrates how modern westernized diets drastically depart from the original diet humans consumed for millions of years. In The Paleo Diet and The Paleo Diet Cookbook, Dr. Cordain shows how diets high in grains, dairy, vegetable oils, salt, and refined sugars are at odds with our genetic legacy and then shares his uncomplicated strategy for losing weight and getting healthy."
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.
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.
It’s also worth noting that athletes who receive a CrossFit Games invitation from a Sanctional event win do not necessarily need to compete in the Open to make it to the Games. Additionally, athletes that place high enough in the Open to receive a bid to the Games, and athletes who are deemed National Champion for their country, will receive no additional benefit (in respects to the Games seeding directly) with a win at a Sanctional event.
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.
In Defense of Food: An Eater's Manifesto by Michael Pollan gives a guided tour of 20th century food science, a history of "nutritionism" in America and a look at the marriage of government and the food industry. Then the book presents a commonsense shopping-and-eating guide, which like the paleo diet focuses on shopping the perimeter of the supermarket. He also now has a much shorter Food Rules: An Eater's Manual.

Autoimmunity is a process in which our bodies own immune system attacks “us.” Normally the immune system protects us from bacterial, viral, and parasitic infections. The immune system identifies a foreign invader, attacks it, and ideally clears the infection. A good analogy for autoimmunity is the case of tissue rejection after organ donation. If someone requires a new heart, lung kidney or liver due to disease or injury, a donor organ may be an option. The first step in this process is trying to find a tissue “match”. All of us have molecules in our tissues that our immune system uses to recognize self from non-self. If a donated organ is not close enough to the recipient in tissue type the immune system will attack and destroy the organ. In autoimmunity, a similar process occurs in that an individuals own tissue is confused as something foreign and the immune system attacks this “mislabeled” tissue. Common forms of autoimmunity include Multiple Sclerosis, Rheumatoid Arthritis, Lupus, and Vitiligo to name only a tiny fraction of autoimmune diseases. Elements of autoimmunity are likely at play in conditions as seemingly unrelated as Schizophrenia, infertility, and various forms of cancer.
The aspects of the paleo diet that advise eating fewer processed foods and less sugar and salt are consistent with mainstream advice about diet.[1] Diets with a paleo nutrition pattern have some similarities to traditional ethnic diets such as the Mediterranean diet that have been found to be healthier than the Western diet.[3][6] Following the paleo diet, however, can lead to nutritional deficiencies such as those of vitamin D and calcium, which in turn could lead to compromised bone health;[1][20] it can also lead to an increased risk of ingesting toxins from high fish consumption.[3]
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.
Sport-specific athletes – Like the specialists, if you are an athlete training for a sport, you’d be better off finding a coach that is trained in getting great performances out of athletes in your specific sport. Every sport has special movements that require certain types of power in specific muscles. CrossFit prepares you for everything, but won’t improve your specific sport skills unless you are training for those specific sport skills! Many athletes choose to combine CrossFit with sport-specific workouts (see things like CrossFit Football) in their off-season for conditioning, but that’s up to each sport’s coach.
