CrossFit Inc. reserves the right to send 4 athletes who have failed to qualify otherwise to the Games. This is a complete CYA move. If a fan favorite fails to qualify through the Open or through a sanctioned event, you can believe Dave Castro will send a quick text message saying, “I got you covered, boo. You've always had the capacity in my eyes <3”.
Advocates of the diet argue that the increase in diseases of affluence after the dawn of agriculture was caused by changes in diet, but others have countered that it may be that pre-agricultural hunter-gatherers did not suffer from the diseases of affluence because they did not live long enough to develop them. Based on the data from hunter-gatherer populations still in existence, it is estimated that at age 15, life expectancy was an additional 39 years, for a total expected age of 54 years. At age 45, it is estimated that average life expectancy was an additional 19 years, for a total expected age of 64 years. That is to say, in such societies, most deaths occurred in childhood or young adulthood; thus, the population of elderly – and the prevalence of diseases of affluence – was much reduced. Excessive food energy intake relative to energy expended, rather than the consumption of specific foods, is more likely to underlie the diseases of affluence. "The health concerns of the industrial world, where calorie-packed foods are readily available, stem not from deviations from a specific diet but from an imbalance between the energy humans consume and the energy humans spend."
For immediate weight loss, Paleo is a great and healthy solution. But after carefully reading and considering, I’m unconvinced that Paleo is optimal for long-term health. I think, in fact, it might lead to heart disease and other ills associated with heavy meat consumption. Although many of Cordain’s theories fall apart long-term, I thoroughly enjoyed the read and highly recommend the book. You should read critically and decide for yourself.
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.
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.
When it comes to humans, we’re all just victims of our own biochemistry. Our brains are controlled and ruled by chemicals - from what we eat; to how and when we sleep; even to who we choose as a life partner. Biochemistry - or ‘biological chemistry’ - is concerned with all of the biochemical reactions which take place within our bodies and brains. This means that the simple act of eating a meal is actually composed of thousands of tiny...
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.
The biggest downside of this diet is how restrictive it is. A month is a pretty long stretch to make it without taking bite of quinoa, popping a chickpea, or sneaking a sip of wine (especially if you’re a busy, social person), and the protocol does not allow for even the smallest of slip-ups. From the manual: “One bite of pizza, one spoonful of ice cream, one lick of the spoon mixing the batter within the 30-day period and you’ve broken the “reset” button, requiring you to start over again on Day 1.” (Yikes!)
The Whole30 book is the perfect thing to read while you’re visiting your in-laws or don’t feel like telling Aunt Sue for the 100th time what you do for a living. It’s helpful, it’s clear, and it will get you motivated. Want even more Whole30 recipes? Hartwig's latest Whole30 Cookbook may not have the nitty-gritty plan details, but the recipes are baller.
I LOVE Whole30. I preach it and I live it. The reason I am only posting 3 stars is because I am really disappointed in this cookbook, which I anticipated for months. I love crockpot meals and soups, and this didn't hardly have anything like that. Most of these meals did not look very appetizing. I don't want to have to purchase odd ingredients for that 1 meal and you'll be doing that with every one of these recipes. I hope they come out with another cookbook that focuses more on altering the more common meals that we are comfortable with.

Similarly, any foods that were not easily available to Paleolithic humans are off-limits in this diet, Holley explains. That means processed foods — many of which contain added butter, margarine, and sugar — should not be a part of the paleo diet. The same goes for dairy, which may not have been accessible to Paleolithic humans, and legumes, which many proponents of the diet believe are not easily digestible by the body.
Trying to devise an ideal diet by studying contemporary hunter-gatherers is difficult because of the great disparities that exist; for example, the animal-derived calorie percentage ranges from 25% for the Gwi people of southern Africa to 99% for the Alaskan Nunamiut. Descendants of populations with different diets have different genetic adaptations to those diets, such as the ability to digest sugars from starchy foods. Modern hunter-gatherers tend to exercise considerably more than modern office workers, protecting them from heart disease and diabetes, though highly processed modern foods also contribute to diabetes when those populations move into cities.
Trick And Treat - how 'healthy eating' is making us ill by Barry Groves. The author is one of the world's most outspoken proponents of a high-fat, low-carbohydrate diet. This book is an account of how and why the health-care establishment has got the concept of 'healthy eating' so wrong. Whereas Taubes work (see above) is a fairly straight forward review of the existing science, Groves expands into the politics of medical research and treatment to a much greater extent. "Trick and Treat" is divided into two parts. Part One describes the corruption in the health industry, points out the problems inherent in a high-carb, low-fat diet, and then prescribes a diet that leads to good health. The prescribed diet is high in fat - specifically animal fat, not polyunsaturated vegetable fat - and low in carbohydrates, with 60-70% of calories from fat, 15-25% of calories from protein, and a mere 10-15% of calories from carbohydrates. Part Two describes numerous diseases the author claims are the result of high carbohydrate consumption. These range from life-threatening disorders such as cardiovascular disease, diabetes, and cancer to less serious problems such as acne, near-sightedness and dental problems. The Amazon reviews average to 4+ stars.
This is one of the best cookbooks I have ever purchased and I have nearly 100! Most cookbooks I might find 3-4 good recipes out of dozens. Out of the 150 recipes in this book there are maybe 10 that I wouldn't make but 140 I would! The pictures are great! The recipes are delicious. I don't really even feel like I'm eating healthy because the food just tastes so great!

Glassman was already familiar with the Anderson case. In May 2005, the owner of the garage gym where the incident took place wrote about it in the CrossFit Journal, the company's online publication. In October, Glassman wrote an article himself, "CrossFit-Induced Rhabdo," in which he soberly explained the circumstances of the six CrossFit-related cases he knew about, outlined ways affiliates could lower the likelihood of injury, and announced he would add a rhabdomyolysis discussion to his weekend seminars and to the website.
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.
After spending a week fine-tuning my new eating plan, I decided to add workouts back into my routine. On a typical week, I'll go to a cardio or strength class (I like boxing) once or twice and do some yoga or stretching at home another night. I dove right in and hit up my favorite boxing studio, Rumble. But I was really nervous. What if I didn't have enough energy? What if I passed out during class? What if I got so hungry I caved and bought a slice of pizza on the walk home from class?
Of course Wikipedia has a page on the Paleolithic Diet. It is quite thorough. It also isn't clear about the lean/fatty meat debate between the followers of Loren Cordain and a slew of others, and pushes lean meat. It is weak on the variations of the diet. Then it restricts fermented beverages. Even butterflies eat fermented fruit. Why wouldn't our paleo ancestors also?
If you've been on the Whole30 and counting down the days until February 1st, step away from the cheese! Before you transition back to your normal diet, here are five solid lessons that I learned from the eating plan that I stuck with even after the 30 days were up. Not only did following them beyond the 30 days prevent me from rebounding back to my higher weight, but they also help keep me on the straight and narrow the rest of the year when I’m not following the program.
Grass-fed beef is often highlighted on the diet, which is promoted to contain more omega-3 fats than conventional beef (due to being fed grass instead of grain). It does contain small amounts of alpha-linolenic acid (ALA), a precursor to EPA and DHA. However, only a small proportion of ALA can be converted in the body to long-chain omega-3 fatty acids (EPA and DHA). The amount of omega-3 is also highly variable depending on the exact feeding regimen and differences in fat metabolism among cattle breeds.  In general, the amount of omega-3 in grass-fed beef is much lower than that in oily marine fish.  Cooked salmon contains 1000-2000 mg of EPA/DHA per 3-ounce portion, whereas 3 ounces of grass-fed beef contains about 20-200 mg of ALA.
This 2003 CrossFit Journal article captures an early conception of a universal, multi-event test of fitness that laid the foundation for CrossFit competition, including what would become the CrossFit Open and the CrossFit Games. The design requirements for such a test "included but were not limited to the following: quantifiable results; consistency with the CrossFit fitness concept; raising our commitment to improving absolute strength, relative strength, and gymnastic foundations; balancing intrinsic abilities of smaller and larger athletes; emphasizing exercises critical to and foundational to advanced training; mixing training demands within each test and, of course, over the total competition; a design that would identify an athlete’s weaknesses and possibly stand as a workout plan for improving overall fitness; and, finally, we wanted to design a competition that would be 'hard as hell.'"
