The plan focuses on unprocessed foods and foods with very minimal, or, better yet, no added ingredients. Whole30 requires dieters to cut out a lot of items, including sugar, dairy and legumes, and then slowly reintroduce these food groups back into their diets after the 30 days. The purpose of the reintroduction phase is to see if any of the foods cut out are the culprit for any health issues.

Don’t pour all the curry sauce over the chicken; once the mixture has come into contact with the raw meat, you have to throw it out. Instead, place your chicken in a shallow bowl, and pour a little of the sauce over the chicken. Brush or rub it evenly over the meat, then flip and repeat on the other side. Save the extra sauce to drizzle over the top of this dish before serving, or use it to top tomorrow night’s chicken, shrimp, or vegetables.
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.[39] Descendants of populations with different diets have different genetic adaptations to those diets, such as the ability to digest sugars from starchy foods.[39] 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.[39]

You start to talk a language nobody understands – talking to a CrossFitter is like talking to somebody in a foreign language. CrossFit people oftentimes forget that nobody outside of CF understands what half the stuff they say means, so they shout out achievements or accomplishments and explain how quickly they did specific exercises…but they don’t realize nobody really cares!
Sugar is almost always manufactured and should be avoided on the paleo diet. This means you’ll need to cut out the delicious but destructive sweets and sugars that are standard in the Standard American Diet. The rule of thumb here is: if it contains a ton of sugar, it’s probably not on the paleo diet friendly. That said, here’s a specific lists of sweets that are not on the paleo diet food list. You might want to take a moment to say goodbye to them before you start your paleo diet journey.
3) A lot of the recipes are what some would consider "exotic" and may need to be sold to kids. Sure, not everyone buying the book has kids but a lot of us do so let's keep it simple. I appreciate some exotic dishes (especially Indian and African foods) here and there and I encourage my kids to try variety but... really... I need more simple recipes that won't meet opposition. Simple, uncomplicated foods without a tons of strong spices. Complicated dishes are appreciated in moderation in cookbooks, not nearly every recipe.
CrossFit gyms use equipment from multiple disciplines, including barbells, dumbbells, gymnastics rings, pull-up bars, jump ropes, kettlebells, medicine balls, plyo boxes,[23] resistance bands, rowing machines, and various mats. CrossFit is focused on "constantly varied, high-intensity, functional movement,"[24] drawing on categories and exercises such as calisthenics,[25] Olympic-style weightlifting, powerlifting, Strongman-type events, plyometrics, body weight exercises, indoor rowing, aerobic exercise, running, and swimming.[26]
I often get caught up in focusing on numbers and scales, so I decided not to officially weigh myself before or after Whole30. But I can attest that everything about my body just felt better. I know saying something like "I lost eleven pounds" would sound much more convincing, but I could see that my stomach was slimmer, as was my face (which is awkwardly the first place I gain weight).

All this said, I still think it's worth buying if you are looking for more variety in your Whole 30 meals. I think the least complicated section is breakfast and lots of them look delicious. However, anticipate that this cookbook may surprise some people who were used to the recipes and format from the 30 Day Guide. This one is definitely more work. I would love to see one like the 30 Day Guide, with more one pot meals, "make it a meal" options, etc...

He also makes a concerted effort to avoid new streams of revenue. (See "CrossFit Doesn't Want Your Money.") CrossFit makes most of its money from training seminars: Every weekend, it certifies hundreds of people as trainers, at $1,000 a pop. It also collects registration fees for the CrossFit Games, royalties from Reebok for CrossFit apparel, and annual affiliate fees. The affiliate fees, which top out at $3,000 a year, are locked in at their original rates. Joshua Newman, who runs a big, successful box called CrossFit NYC, told me he pays just $500 a year.
Videos shot with a fisheye lens or similar lens may be rejected due to the visual distortion these lenses cause. If an athlete needs someone to adjust their camera during the WOD to capture all movements, this is acceptable, as long as the flow of the workout and the athlete is in view the whole time. It is the athletes responsibility to ensure their video meets the standard.
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.[29] 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.[30] At age 45, it is estimated that average life expectancy was an additional 19 years, for a total expected age of 64 years.[31][32] 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."[33]

In making the case for meat, Cordain presents anecdotal evidence of Eskimos who lived their full life without a heart attack. The Eskimo diet consists of 97% meat, which he concedes causes all Eskimos to develop atherosclerosis—a common precursor to heart disease. But Cordain says Eskimos never die of heart disease. He discusses one Eskimo who lived 45 years and another who lived 53 years, both without heart disease! He then jumps to the conclusion that because these Eskimos didn’t get heart attacks, even with severe atherosclerosis, meat must have protected them from heart disease. So Cordain’s best case for lots of meat is that you can live to the ripe age of 45 or even 53 without a heart attack. But do people—even unhealthy smokers or the obese—generally get heart attacks before age 53?

"CrossFit is not a specialized fitness program, but a deliberate attempt to optimize physical competence in each of 10 recognized fitness domains," says founder Greg Glassman in the Foundations document. Those domains are cardiovascular and respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy.[33]
