As a result, his company's revenue (set to double this year, to $100 million) is fueled almost completely by CrossFit's rampant proliferation. Meanwhile, a burgeoning ecosystem of other businesses has risen up to cater to these squatting, thrusting fiefdoms. There are multiple apparel companies; food and beverage companies (serious CrossFitters are often serious about the Paleo Diet); businesses that cater specifically to box owners, with iPad apps that track workouts and manage membership rolls; business consultants who show box owners how to increase their revenue. A Web design firm specializes in CrossFit box sites. There are even two print magazines, The Box and WOD Talk.

1) During a CrossFit workout, you’re often told to complete a number of strength training or endurance exercises as fast as possible, or complete as many repetitions as possible in a certain amount of time. For that reason, it’s REALLY easy to sacrifice form in exchange for finishing the workout quicker. If you don’t have somebody spotting you or telling you to keep your form correct, then you’re in trouble.
But listen--we'd both been relatively inactive for years and each about 25 pounds overweight. Between the two of us we lost 34 lbs in 30 days and we are still going to keep up a serious commitment to Whole 30, with a few supplemental treats now and then. We feel better, we have new confidence about getting dressed in the morning, and we're more fit than in years, mostly because we have the energy to do more. The amazing thing is that you will NOT feel hungry if you hang in there and consistently prepare foods as per the cookbook/menus. There is also a very supportive and helpful forum online to supplement the book.
In William Calvin's The Ascent of Mind, Chapter 8 he discusses why he thinks that the Acheulian hand-ax (the oldest of the fancy stone tools of Homo erectus) was really a "killer frisbee." He argues that natural selection for throwing accuracy, which requires brain machinery, is the evolutionary scenario for bootstrapping higher intellectual functions. There are many more articles about evolution and human development throughout William's extensive site, though much of it these days is on climate change.
Food in Antiquity: A Survey of the Diet of Early Peoples (Expanded Edition) by Don R. Brothwell and Patricia Brothwell is a survey of what is known archaeologically about food and drink in pre-modern times. The chapter on insects includes their food value. In beverages it covers what happens to a neglected jar of fruit juice. Under cannibalism it shows evidence of this being done in paleo times, thought most of the work focuses on the classical and near-eastern civilizations, but occasional mention is made of the mesoamerican cultures as well. There is taxonomic and anatomical information.

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

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.
On 4 June 2014, CrossFit uploaded a "parody video to their Facebook page" of Jesus, featuring concepts such as the "Holy Trinity of exercise".[83] Yasmine Hafiz wrote in The Huffington Post that some "viewers are outraged at the disrespectful use of a Christian symbol", with one user asking "on what planet is it comical or encouraged to mock someones belief?"[84][83]
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.
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.
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.
Odd programming – As you’ll read in another critique later in this article, I don’t agree with some of the workouts that are prescribed at some CrossFit gyms. For example, some workouts might call for high reps of snatches; these are an Olympic lift that require perfect form in order to be done successfully. Doing 30 reps of them is a sure-fire way to sacrifice form and dramatically increase the risk for injury.
Legumes are members of a large family of plants that have a seed or pod. This category includes all beans, peas, lentils, tofu and other soyfoods, and peanuts. Legumes are not allowed on paleo because of their high content of lectins and phytic acid. Similar to grains, this is a point of controversy in the scientific community. In fact, lots of research supports eating legumes as part of a healthy diet because they are low in fat and high in fiber, protein and iron.
CrossFit is a strength and conditioning program consisting mainly of a mix of aerobic exercise, calisthenics (body weight exercises), and Olympic weightlifting.[19] CrossFit, Inc. describes its strength and conditioning program as "constantly varied functional movements executed at high intensity across broad time and modal domains,"[20] with the stated goal of improving fitness, which it defines as "work capacity across broad time and modal domains."[21] Hour-long classes at affiliated gyms, or "boxes", typically include a warm-up, a skill development segment, the high-intensity "workout of the day" (or WOD), and a period of individual or group stretching. Some gyms also often have a strength-focused movement prior to the WOD. Performance on each WOD is often scored and/or ranked to encourage competition and to track individual progress. Some affiliates offer additional classes, such as Olympic weightlifting, which are not centered around a WOD.[22]
