The Paleolithic Prescription: A Program of Diet & Exercise and a Design for Living by S. Boyd Eaton, M.D., Marjorie Shostak and Melvin Konner. This book, published in 1988, was the start of the Paleolithic diet movement. Its recommendations are not in line with what today is considered a paleo diet, as whole grain breads and pastas, legumes and some low fat dairy products are allowed. However, it is still a profoundly important book. Used books are available for a reasonable price.
Between 2009 and 2018, competitors qualified for the Games through participation at CrossFit Games regional events. For the 2019 Games, CrossFit, Inc. discontinued hosting the Regional qualifier and instead sanctioned independent fitness events as qualifiers separate from the Open. Most of the sanctioned events were already widely participated in by CrossFit Games athletes, often used as a part of off-season training, around the world. Each sanctioned event has its own rules for participation, but athletes that attend the sanctioned events are either by invite or through the event's qualification process.
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]
The barbell may be pre-loaded to a start weight. The athlete has to load their own bar. No pit crews or assistance is allowed. The barbell must start on the ground. The athlete may then lift the bar from the ground and get it to an overhead position in any variation detailed above. As long as they are locked out with hips and knees at full extension before starting each rep. However, you may squat snatch the first rep if you wish.

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.

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.


People who never had good social group experiences like it because, even if they are crazy, CF communities are always positive, supportive, and good-natured. CF brings people together and makes them compete every day in a society that shies away from competition. The challenge creates a heightened sense of self worth that develops into being an elitist..

ICYMI: Whole30 is an elimination-style diet that asks dieters to ban all soy, dairy, grains, alcohol, legumes, and added sugars from their diet for 30 days straight. The point is to flush your system, so when the 30 days are up, you can slowly add different food groups back and get a sense of which ones have been secretly affecting your physical and mental health. The creator, Melissa Hartwig, also says Whole30 will change your entire relationship with food.
A metaresearch group at Tilburg University in the Netherlands investigates scientists’ research methods and operations, scrutinizing questionable practices such as selective reporting of statistical tests and data massaging. The group instead advocates for practices such as preregistering studies and making experimental data immediately available for open external review and verification. Its members are optimistic that “the perverse incentives of careerist academia, to hoard data and sacrifice rigor for headline-generating findings, will ultimately be fixed.”
