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.
In the Rulebook CrossFit, Inc. writes,“Should the winner of a Sanctionals competition qualify for or receive an invitation to the Games by another means, the second-place athlete/ team from that Sanctionals competition will receive the invitation to compete at the Games. This backfill process will continue if the second-place athlete/team has already qualified, received an invitation, and so on.”
2) CrossFit attracts a certain type of person – namely folks who push themselves so hard they actually do bodily harm. Ask any CrossFitter if they’ve met “Pukey the Clown” and they’ll probably tell you yes. Due to the nature of competition, the motivating atmosphere, and people’s desire to do well, many people in CrossFit often push themselves beyond their personal limitations (which can be a good thing)…but oftentimes they push themselves too far.
My fiancee and I did this together. It takes teamwork (if you have a family, you probably need to get them on board). It also will help if you can begin (or even complete) this diet when you have a minimum of social obligations--having office mates who eat a lot of cake or friends who drink a lot of booze WILL NOT HELP while you are on this program. Don't try to start this the week before Christmas if your family gathers to eat until they pass out. Be realistic about when you begin this. You must prepare a little bit and read the book ahead of time so you aren't just floating at sea. And, be aware: you will not be able to sufficiently screen foods made by other people!
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.
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.
I believe the 2019 open is an epic fail. While I agree, CrossFit is a world wide sport, showcasing athletes from every country the new format leaves me confused and has deflated my motivation to compete this year. Like most professional sports, the media experience drives the interest of the fans for each competition. You don’t see other major sports get rid of their media teams in the hopes of attracting new fans in other countries. Those countries develop their own media teams for content, broadcasting etc. I’ve been a cross fit athlete before it was “cool” and have been a level 1 certified trainer. I looked forward to the open because it brought the “average” athlete into the world only few see. The announcements are weak, in another language and of poor content. Was this really your best option, scrap the entire media staff? Which in turn meant you took away all of usual vidoes, blogs, vlogs, articles etc. we’ve grown accustom to seeing each year. I’m disappointed because you’re better than that, smarter as a brand. Imagine the NFL, MLB, NBA (because that’s where Cross Fit was heading as a brand) get rid of all media content to boost global attention by taking away everything the fans used, looked forward to and relied on for information across each media domain. It’s virtual brand suicide. Just like your affiliates, which pop up at every available garage door….you develop media teams for each nation. You don’t scrap what’s working and alienate your core audience.
Re: “Too old masters’ age group”… I have zero insight as to whether or not this will happen, but I’m a betting man & I’m putting my money on yes. If CrossFit lasts, which I think it will, I believe they’ll continue to evolve as the sport grows in size and age. It’ll come down to how many “too old” athletes end up being serious competitors. You’ll lead the way.
The digestive abilities of anatomically modern humans, however, are different from those of Paleolithic humans, which undermines the diet's core premise. During the 2.6 million year-long Paleolithic era, the highly variable climate and worldwide spread of human populations meant that humans were, by necessity, nutritionally adaptable. Supporters of the diet mistakenly presuppose that human digestion has remained essentially unchanged over time.

Research into the weight loss effects of the paleolithic diet has generally been of poor quality. One trial of obese postmenopausal women found improvements in weight and fat loss after six months, but the benefits had ceased by 24 months; side effects among participants included "weakness, diarrhea, and headaches". Any weight loss caused by the diet was merely the result of calorie restriction, rather than a special feature of the diet itself.
CrossFit is a strength and conditioning program consisting mainly of a mix of aerobic exercise, calisthenics (body weight exercises), and Olympic weightlifting. CrossFit, Inc. describes its strength and conditioning program as "constantly varied functional movements executed at high intensity across broad time and modal domains," with the stated goal of improving fitness, which it defines as "work capacity across broad time and modal domains." 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.
