ICYMI: Whole30 is an elimination-style diet that asks dieters to ban all soy, dairy, grains, alcohol, legumes, and added sugars from their diet for 30 days straight. The point is to flush your system, so when the 30 days are up, you can slowly add different food groups back and get a sense of which ones have been secretly affecting your physical and mental health. The creator, Melissa Hartwig, also says Whole30 will change your entire relationship with food.
Glassman is proud of his role in all this, but the system puts him and CrossFit at a very real risk. As the world of CrossFit grows, as more businesses enter and profit, and his share of it becomes smaller, CrossFit's greatest success--gaining mainstream acceptance as exercise and a sport--could turn it generic, like baseball or skiing. "One of our greatest fears is becoming escalator," says Dale Saran, CrossFit's general counsel, referring to what was once a trademarked name brand of Otis Elevator. So, although Glassman keeps the CrossFit business model radically loose and open, he protects the brand name with an iron fist.
Primal Blueprint Quick and Easy Meals: Delicious, Primal-approved meals you can make in under 30 minutes by Mark Sisson and Jennifer Meier. Every recipe is accompanied by an ingredient list, a nutrient list, clearly written instructions, and a picture of the ingredients and a picture of the finished product. Note that this is a primal book and many recipes include dairy. Published March 25, 2011.
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].
Excluding foods. The exclusion of entire categories of commonly eaten foods like whole grains and dairy requires frequent label reading in the supermarket and in restaurants. It may also increase the risk of deficiencies such as calcium, vitamin D, and B vitamins, if these nutrients are not consistently eaten from the allowed foods or a vitamin supplement. For example, there are some nondairy calcium-rich foods that are absorbed well by the body such as collard and turnip greens or canned bone-in sardines and salmon, but you would have to eat five or more servings of these greens and fish bones daily to meet recommended calcium needs. (Note that some greens like spinach that are touted to be calcium-rich also contain oxalates and phytates that bind to calcium so very little is actually absorbed.) One small, short-term intervention study of healthy participants showed a 53% decrease from baseline in calcium intake after following a Paleo diet for three weeks.  Furthermore, the exclusion of whole grains can result in reduced consumption of beneficial nutrients such as fiber and thus may increase one’s risk for diabetes and heart disease.
Paleonutrition by Mark Q. Sutton, Kristin D. Sobolik, and Jill K. Gardner is the analysis of prehistoric human diets and the interpretation of dietary intake in relation to health and nutrition. This is a substantial text that combines background to paleonutrition, an extensive bibliography, a discussion on methods, and case studies. Published February 23, 2010.
It should be noted that U.S. News & World Report just released its annual ranking of diets, and Whole30 ranked dead last. Why? Essentially, the expert panel of over 20 registered dietitians, academics, and medical doctors found the program unsustainable and potentially unhealthy, since, among other issues, it restricts certain food groups and is high in sodium and cholesterol. But, Whole30's co-creator Melissa Hartwig stands behind the program, telling Cosmopolitan.com that its animal protein recommendations are in line with government recommendations, and that there are no nutrients in temporarily restricted foods, like grains and legumes, that you can't find in fruits and vegetables.
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.
The Games include age-based divisions for younger and older competitors. Masters divisions were introduced at the 2010 Games. There are currently six divisions each for women and men: 35–39, 40–44, 45–49, 50–54, 55–59, and 60+. Divisions for teenagers were introduced in 2015: the age ranges are 14–15 and 16–17, for both boys and girls. Rather than regional events, masters and teen athletes qualify for the games by a second online competition following the Open. The top 200 athletes in each division worldwide are invited to compete in this qualifier, of which the top 20 (top 10 as of 2019) advance to the Games. Prior to the introduction of these secondary online qualifiers, masters and teens competitors qualified for the Games directly from the Open.
Similarly, any foods that were not easily available to Paleolithic humans are off-limits in this diet, Holley explains. That means processed foods — many of which contain added butter, margarine, and sugar — should not be a part of the paleo diet. The same goes for dairy, which may not have been accessible to Paleolithic humans, and legumes, which many proponents of the diet believe are not easily digestible by the body.
As with paleo, doing keto for more than a few weeks could lead to nutrient deficiencies according to Andy Yurechko, MS, RD, of Augusta University Medical Center in Georgia . He says lack of fiber is the biggest concern for keto fanatics, who may experience constipation. But it's possible to get fiber by eating lower-carb vegetables like broccoli and chia seeds.
In his gruff way, Glassman recounted his story for the faithful: how a novel, exquisitely punishing system of exercise he had designed, centered on the WOD (workout of the day; it's pronounced "wad"), had started in his backwater Santa Cruz gym, then turned into an online phenomenon, then paved the way for 6,775 CrossFit locations (soon to be 10,000), and now was fast becoming its own sport. (This month, the finals of the CrossFit Games will be broadcast live on ESPN2.) He explained the contrarian way he thinks about the CrossFit business (he shuns most new sources of revenue) and how he goes about protecting its brand (viciously).
The final workout of the 2019 Open featured a descending ladder of thrusters and chest-to-bar pull-ups, totaling 105 reps of each movement, with a 20-minute time cap. Last year, 18.5 presented athletes with an ascending ladder of the same two movements, so it’s no surprise that nearly the same percentage of Open participants decided to tackle the final Open workout as prescribed in 2018 and 2019. Read on to see how the community fared with this year's rep scheme.
