Level One (CF-L1) is the introduction level, where participants attend a group weekend class, talk about the basic methodology and fundamentals of CrossFit, and learn how to conduct their own classes. They go over techniques and how to adjust them for those who cannot perform them. After completing the Level One training course, one should be confident in conducting a class, scale workouts accordingly for athletes, and hold CrossFit to its standards.[50] In the second level, training goes deeper into the mechanics of the movements and how to be leaders and communicate with other students. In the Level Two course, participants learn about athletic capacity and are evaluated as a trainer in groups.[51] In order to earn the Level Three certificate, a coach one must complete 1,500 hours of active fitness coaching and become CPR certified. To earn the Level Four certificate, the highest level currently recognized by CrossFit, Inc., the coach must record several years as a Level Three and pass a test.[52]
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.
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?
The Open, introduced in 2011 and so-called because participation is open to anyone,[23] is held over five weeks in February–March; a new workout is released on each Thursday night (Pacific Time) and competitors complete the workout and submit their scores online by Monday evening, with either a video or validation by a CrossFit affiliate. Since 2013, Open workout announcements have been broadcast live, and featured two or more past CrossFit Games athletes competing head-to-head immediately following the workout description. Beginning with the 2019 Games, the top athlete from each country and the top 20 overall Open finishers qualify directly to the Games. The Open is also used for seeding purposes at the Games even if an athlete qualified through the sanctioned events; if an athlete qualifies through a sanctioned event but does not do the Open, they will be seeded at the bottom.
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.
The following links tend towards news reports of scientific studies that point out some positive aspect of the paleo diet. If you are looking for current news reports, I suggest signing up for Google Alerts for the Type: News. I have three set up, for: "caveman diet," "paleo diet," and "paleolithic diet." You can also set them up for blogs and/or websites.
These are great! Thanks. I was wondering what your budget is for all this food. I seem to spend much more money for groceries when we are on whole 30. I try to shop at Costco and discount stores as I can, but it still seems like a lot. My shopping list I created for week one on my previous w30 was like $350 for a family of 5 (including food for one vegan). Is this normal?
Thank you CFA coaches for always scaling the WOD for my medical needs, but still making the WOD fun and challenging. I may not be able to lift heavy or ever be a part of the CF games, but I do feel like a part of CFA family and with that I could never go back to a gym. It’s been a privilege meeting and working out with great people. I feel honored to be selected CFA Athlete of the Month. CROSSFIT PROUD!!!
You’ll be exposed to a ton of new, delicious recipes. If you know you’re not the cooking type, start simple. Instead of making the fancy egg-bake in a cast-iron pan, grab some eggs, veggies, sausage, and avocado then scramble your breakfast. Top it with (sugar-free) hot sauce, and you'll have yourself a solid meal in seven minutes. Don't be afraid to make that for breakfast five times a week; making similar meals over and over again is easier than trying to whip up (new) complicated ones.
For the wall-ball, the athlete must start with the ball at a dead stop on the ground. The athlete may then pick up the ball and stand tall before beginning a set, or squat clean the ball, before beginning their first repetition of any set. An athlete may not start in a squat, pick up the ball from this position, and toss the ball to the target. A repetition consists of an athlete holding the ball in the “front rack,” and performing a full squat, hip-crease passing below the top of the knee, and when vertically extending throwing the ball to a specific target height. If the athlete’s hip does not break parallel, or the target does not touch the wall, that rep will not be counted. The athlete may then catch the ball and perform multiple reps if they so choose. Finally, athletes may not catch the ball on the bounce, and head right into a wall-ball repetition. The ball must be settled on the floor before picking it up to begin another set.

That severe carb restriction is meant to keep your body in a state of ketosis, says Alyssa Cohen, R.D. “Ketosis refers to the state of relying on ketone bodies for fuel,” Cohen explains. “Fat is the source used to make ketone bodies, so this diet aims to use fuel from fat, rather than carbohydrates [what our bodies primarily use for energy].” So basically, the keto diet helps you speed up the weight-loss process through fat burning.
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!
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.
But critics argue that the unlimited amount of red meat the paleo diet allows may have an adverse effect on heart health in people with diabetes, as research links eating red meat in excess to poor heart health. (11)  If you have diabetes and don’t moderate your red-meat intake, this could be a big problem, as people with diabetes are 2 times as likely to die of heart disease as people who do not have diabetes.

The WHO trial (so named because the international team of principal investigators contained World Health Organization members) tested the potential of clofibrate, a “pre-statin” cholesterol-lowering agent, to reduce heart attack morbidity and mortality. The investigators ultimately concluded that clofibrate "cannot be recommended as a lipid-lowering drug for community-wide primary prevention of ischaemic heart disease.” Nevertheless, clofibrate remained in use until 2002, when it was pulled for increasing cancer rates. In their review of studies such as the WHO trial, Uffe Ravnskov and David Diamond observe, “Despite the largely disappointing findings from 50 years of cholesterol lower[ing] trials, the indictment and conviction of cholesterol as the causal agent in CVD [cardiovascular disease] has stood the test of time. … [Yet] the grand effort to reduce cholesterol as a strategy to improve health has failed.”
