CrossFit, Inc. licenses the CrossFit name to gyms for an annual fee and certifies trainers. Besides the standard two-day "Level 1 Trainer Course", specialty seminars include gymnastics, Olympic weightlifting, powerlifting, strongman, running and endurance, rowing, kettlebells, mobility and recovery, CrossFit Kids, CrossFit Football, and self-defense and striking. Other specialized adaptations include programs for pregnant women, seniors, and military special operations candidates. Affiliates develop their own programming, pricing, and instructional methods. Many athletes and trainers see themselves as part of a contrarian, insurgent movement that questions conventional fitness wisdom. In addition to performing prescribed workouts, they follow CrossFit's nutrition recommendations, adopting a paleo and/or zone diet.
This does require effort. Grocery shopping, meal planning, dining out, explaining the program to friends and family, and dealing with stress will all prove challenging at some point during your program. We’ve given you a huge number of tools, advice, and resources, but take responsibility for your own plan. Improved health, fitness, and quality of life doesn’t happen automatically just because you’re now taking a pass on bread.
Diana Schwarzbein is another M.D. that has come to realize that low carb is what works. See reviews at The Schwarzbein Principle. The book is based on her work with insulin-resistant patients with Type II diabetes. She concludes that low-fat diets cause heart attacks, eating fat makes you lose body fat, and it's important to eat high-cholesterol foods every day.

Lutein/Zeaxanthin and Macular Health is an article discussing antioxidents and protection against the oxidizing ultraviolet radiation of the sun. The best dietary sources of antioxidants in general, and carotenoids specifically, are fruits and vegetables and the more brightly colored, the better. Lutein and zeaxanthin are yellow pigments found in high concentrations in yellow fruits and vegetables as well as in dark green, leafy vegetables. In particular, spinach, kale and collard greens contain high levels of these two carotenoids.
For many years Arthur De Vany Ph.D. has been writing a book called Evolutionary Fitness on "What Evolution Teaches Us About How to Live and Stay Healthy." The diet he follows fits into my core diet definition. He may have been the first one to use the paleo diet to maximize fitness. His current site is Art's Blog on Fitness, Health, Aging, Nutrition and Exercise [archive.org].
If you have more questions on specific foods, we’ve included a comprehensive list of paleo diet foods below. We’ve provided a list of the foods that are allowed on the paleo diet.

In addition to all of that, we’ve also included a comprehensive list of foods not allowed on the paleo diet.
Whether you’re brand new to the program or returning after a long break, this track will take you from contemplation to action in just eight easy steps. Take as much time as you need to explore each step before moving on to the next, but we encourage you to review each step in order—even if you’re impatient to get started. As you’ll hear over and over again, when it comes to the Whole30, planning and preparation are key!
We love nuts and they are decidedly paleo diet friendly. Be careful though, as cashews are high in fat and, for some reason, it’s incredibly easy to eat an entire jar of them in one sitting (that’s not just us, is it?). If you’re trying to lose weight, limit the amount of nuts you’re consuming. Otherwise, have at it. I mean, you can’t beat a good almond/pecan/walnut mix, can you?
Fattening cattle with corn changes the lipid balance and is clearly not the natural diet for a grass eating cow. In Simple change in cattle diets could cut E. coli infection researchers have found that when cattle were fed hay or grass for just five days before slaughter, much less E. Coli cells were present in the animal's feces and virtually all surviving E. coli bacteria were not acid-resistant and were killed by human stomach acid.
