First of all, it’s unclear if it can really live up to its claim to improve overall health by following the diet of our ancestors. While we can all benefit from reducing our intake of processed foods and increasing fruit and vegetable consumption, many dispute whether our ancestors were really all that much healthier than we are today given their significantly shorter life span. In fact, one study even demonstrated that they may have had increased rates of atherosclerosis, or hardened arteries. (5)
It was within this context that Glassman began ramping up his affiliation program. This was growth without a safety net: Anyone who passed his two-day seminar could apply to open a box, call it CrossFit, and then rush paying customers through squats and snatches or whatever crazy WOD they dreamed up. To Glassman, himself a passionate libertarian, this was the right thing to do: He wants his affiliates to be free to open up a box in a garage or a warehouse or wherever else, and train how they want, and charge what they want. They should have the opportunity he had. He detests supposed experts who say their certification or education makes them better than him or his people. At the end of the day, he believes, the free market will provide all the necessary quality control.

The Whole30 program is only 30 days, but it’s a very restrictive 30 days. You’re urged to eat real, whole foods, including lots of veggies, while carving out things like sugar, grains and dairy. There is no “cheating” – even a chew of sugar-free gum or splash of skim milk in your coffee sends you right back to day one so the body can completely heal from inflammatory foods, diet co-creators Melissa Hartwig and Dallas Hartwig say.A couple things you don’t have to worry about on the Whole30 plan are counting calories and weighing or measuring yourself. In fact, the plan forbids the latter in order to bring participants’ attention to the benefits of healthy eating outside of weight loss. If you usually go out to eat or order take-out, you’ll need to learn to meal prep, grocery shop (with a plan!) and cook. If you’re a social butterfly, you’ll need to strategize how to order water and carrot sticks at the bar instead of beer and wings – or stay home. Fortunately, the program’s resources suggest solutions to these and other conundrums that may pop up. What’s more, the program’s strong emphasis on social – much of it virtual – support can keep participants inspired and accountable.The Whole30 program is outlined neatly online, where followers can read FAQs, lists of foods that are and aren’t off-limits and download a program guide. Melissa Hartwig’s latest book, “Food Freedom Forever: Letting Go of Bad Habits, Guilt, and Anxiety Around Food,” details how to stay in control of food, rather than allowing it to control you, for a lifetime.
LOREN CORDAIN, Ph.D., is one of the top global researchers in the area of evolutionary medicine. Generally acknowledged as the world's leading expert on the Paleolithic diet, he is a professor in the Health and Exercise Science Department at Colorado State University. Dr. Cordain and his research have been featured on Dateline NBC and in the New York Times, the Wall Street Journal, and other media. He is the author of The Paleo Diet and The Paleo Diet Cookbook, among other books, and makes regular media and speaking appearances worldwide.
CrossFit, Inc. licenses the CrossFit name to gyms for an annual fee and certifies trainers.[37] Besides the standard two-day[38] "Level 1 Trainer Course",[39] 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.[40] 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.[41] In addition to performing prescribed workouts, they follow CrossFit's nutrition recommendations, adopting a paleo and/or zone diet.[42]
On Day 4, I reached for a beef jerky stick from Epic. I simultaneously took a big bite while turning over the packaging to read the label. When I saw it on the ingredients list, I stopped mid-chew: "honey." I immediately spit the partially chewed jerky in my garbage can. Close one. After that, I always read the labels on my food twice before eating a morsel.
Paleo critics point out that not all grains are created equal—whole grains do not spike your blood sugar as much as refined grains. Even so, paleo dieters still steer clear of grains because they contain different compounds and proteins like gluten, lectins and phytates, which they claim cause inflammation in the body and block other nutrients from being absorbed. Paleo critics say these compounds are not a problem unless you have an allergy or sensitivity.

According to the model from the evolutionary discordance hypothesis, "many chronic diseases and degenerative conditions evident in modern Western populations have arisen because of a mismatch between Stone Age genes and modern lifestyles."[25] Advocates of the modern paleo diet have formed their dietary recommendations based on this hypothesis. They argue that modern humans should follow a diet that is nutritionally closer to that of their Paleolithic ancestors.

In Defense of Food: An Eater's Manifesto by Michael Pollan gives a guided tour of 20th century food science, a history of "nutritionism" in America and a look at the marriage of government and the food industry. Then the book presents a commonsense shopping-and-eating guide, which like the paleo diet focuses on shopping the perimeter of the supermarket. He also now has a much shorter Food Rules: An Eater's Manual.


As far as food goes, you’re simply going to eat a lot of fresh, good-quality eats and ditch the processed stuff. Beyond that, you’re removing all grains, dairy, soy, legumes, sugar, artificial sweeteners, and alcohol from your diet. All of these foods (especially in excess), according to the authors, have been linked to systemic inflammation, hormonal imbalance, gut issues, and more. The idea is to remove the stressors from your body and give it the nourishment and time to heal itself it needs. This means less inflammation, a healthy metabolism, hormonal harmony, a happy gut, clearer skin, and improved energy! Sounds good to me. (Although if we’re honest, I panicked a bit when I realized no cheese would hit my lips for a full month.)
Do not eat grains. This includes (but is not limited to) wheat, rye, barley, oats, corn, rice, millet, bulgur, sorghum, sprouted grains, and all gluten-free pseudo-cereals like quinoa, amaranth, and buckwheat. This also includes all the ways we add wheat, corn, and rice into our foods in the form of bran, germ, starch, and so on. Again, read your labels.

Cordain argues that chimpanzees and horses avoid meat, and they have big bellies that we would have if we didn’t ditch plants for meat. He also says meat increased human brain size, and decreased stomach size so we can have the six-pack abs that chimps can’t. But I looked at his endnotes with citations to research and couldn’t find the source for these theories. I also couldn’t find research showing that legumes and grains were invented by humans.


Peel/slice/dice all vegetables and store them in food storage containers in the refrigerator. Carrots, peppers, and potatoes should be stored in water to keep them from drying out and browning. Brussels sprouts should be stored in a dry container. This will drastically cut down on meal prep time each evening and will allow you to have fresh veggies on hand if you need a quick snack between meals.
Greg Glassman and Lauren Jenai founded CrossFit, Inc. in 2000.[14][15] The company was conceived a few years earlier, in 1996, as Cross-Fit.[16] The original CrossFit gym is in Santa Cruz, California, and the first affiliated gym was CrossFit North in Seattle, Washington; there were 13 by 2005, and today there are more than 13,000.[6] Coaches associated with CrossFit include Louie Simmons, John Welbourn, Bob Harper, and Mike Burgener.[17]
