The CrossFit Games is an athletic competition sponsored by Crossfit Inc. and Reebok. The competition has been held every summer since 2007. Athletes at the Games compete in workouts that they learn about hours or days beforehand, consisting mostly of an assortment of standard aerobic, weightlifting, and gymnastics movements, as well as some additional surprise elements that are not part of the typical CrossFit regimen such as obstacle courses, ocean swimming, softball throwing, or ascending a pegboard. The CrossFit Games stylizes their individual winners as the "Fittest on Earth".
With a very simple shift we not only remove the foods that are at odds with our health (grains, legumes, and dairy) but we also increase our intake of vitamins, minerals, and antioxidants. Here is a great paper from Professor Loren Cordain exploring how to build a modern Paleo diet: The nutritional characteristics of a contemporary diet based upon Paleolithic food groups. This paper also offers significant insight as to the amounts and ratios of protein, carbohydrate and fat in the ancestral diet.
The Paleo concept is new for most people and this newness can spark many questions. We like people to not only read about and educate themselves on this topic but also to “get in and do it.” Experience is perhaps the best teacher and often cuts through any confusion surrounding this way of eating. Now, all that considered, there are still some common counter arguments to the Paleo diet that happen with sufficient frequency that a whole paper was written on it. Enjoy: Evolutionary Health Promotion. A consideration of common counter-arguments.
To get an idea of what that means, we turned to the experts, including Loren Cordain, PhD, a professor emeritus at Colorado State University in Fort Collins, Colorado, and the author of The Paleo Diet; Erin Holley, RD, of Ohio State University Wexner Medical Center in Columbus, Ohio; and Lona Sandon, PhD, RD, an assistant professor of clinical nutrition at the University of Texas Southwestern Medical Center in Dallas.
Grass-fed beef is often highlighted on the diet, which is promoted to contain more omega-3 fats than conventional beef (due to being fed grass instead of grain). It does contain small amounts of alpha-linolenic acid (ALA), a precursor to EPA and DHA. However, only a small proportion of ALA can be converted in the body to long-chain omega-3 fatty acids (EPA and DHA). The amount of omega-3 is also highly variable depending on the exact feeding regimen and differences in fat metabolism among cattle breeds.  In general, the amount of omega-3 in grass-fed beef is much lower than that in oily marine fish.  Cooked salmon contains 1000-2000 mg of EPA/DHA per 3-ounce portion, whereas 3 ounces of grass-fed beef contains about 20-200 mg of ALA.
Plus, I feel like the way I eat directly affects my mood. If I eat sugar, I almost always feel like garbage. If I eat protein and veggies and tons of avocado, I feel stable and much less like I am going to have a stage-four meltdown. Blood sugar swings are also real — no one wants to deal with me when I am hangry. It’s a nightmare. This program is supposed to help with all these things. I desperately wanted to feel better, so I dove in.
The burpee box over starts with the athlete facing the box, the athlete must be square and head forward to the box. NO lateral burpees allowed. The athletes chest and thighs must touch the ground on the bottom of the burpee. The athlete may jump or step onto the box and off the box. Whether jumping or stepping, BOTH feet must make contact with the top of the box at the same time. Coming off the box, the athlete must turn around and be face forward on to the box to perform their next burpee.
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!
Generally speaking, dieters are advised to eat between 20-30 grams of carbohydrates per day in order to maintain ketosis. To put this into perspective, a quarter cup of steel cut oats has 29 grams of carbs and a banana has roughly 27 grams of carbs. So if you have a few bites of oatmeal or a small piece of fruit, whoops! That's your carb intake for the day.
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.
It was in Glassman's own divorce case, though, that the CrossFit defense arsenal launched its full firepower. Lauren and Greg's marriage hit the rocks in 2009. Lauren became pregnant with twins and could no longer travel to the seminars.Greg, wrapped up with CrossFit, became more and more distant. Rumors of infidelity swirled. Soon the two were living in separate houses. In March 2010, Lauren officially filed for divorce. But the case didn't come to a head until July 2012, when Lauren filed a motion to sell her 50 percent stake in the company to Anthos Capital, a Menlo Park, California-based venture capital firm, for $20 million. Glassman, and in short order CrossFit, hit the ceiling.
In July 2016, a New York Times article on use of Instagram by dieters noted that participants in the Whole30 program had shared over one million Instagram posts using the #Whole30 hashtag, and noted that those sharing the tag were "one of seemingly endless like-minded communities," comparing it with the over 3.5 million posts under the #WeightWatchers hashtag.
The NY Times had a blog article on Good News on Saturated Fat which is reporting on Gary Taubes's interpretation of the new report in The New England Journal of Medicine on a two-year diet experiment in Israel. A followup is the post The Fat Fight Goes On where Gary rebuts the arguments against the study. And here's a good interview with Taubes (and includes a good summary): Gary Taubes on Cold Fusion, Good Nutrition and What Makes Bad (and Good) Science.
Greg Glassman and Lauren Jenai founded CrossFit, Inc. in 2000. The company was conceived a few years earlier, in 1996, as Cross-Fit. 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. Coaches associated with CrossFit include Louie Simmons, John Welbourn, Bob Harper, and Mike Burgener.
