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.
I’m not going to say I didn’t have some pretty difficult moments. For example, don’t purchase an ice cream maker the day you start your Whole30 and let it sit in your entryway for 30 days to taunt you. I did that; it was dumb. Also, there were points in the program on those days when I felt off that I broke down or wanted to throw in the towel. Feeling bad on top of the normal Lyme symptoms wasn’t great, but I’m glad that I stuck it out.
Ideally one should eat a wide variety of proteins from as many animal sources as possible. One need not and should not avoid fatty cuts of meat, particularly if consuming pastured sources. An often overlooked piece of the paleo diet in popular culture is an over-reliance on standard cuts of meat, at the expense of organ meats, bone broth and other collagen sources. For more information on the historical and practical aspects of consuming a more balanced protein intake, check out the Weston A. Price Foundation. If weight-loss is a goal, protein makes you feel satisfied between meals.
The aspects of the paleo diet that advise eating fewer processed foods and less sugar and salt are consistent with mainstream advice about diet. Diets with a paleo nutrition pattern have some similarities to traditional ethnic diets such as the Mediterranean diet that have been found to be healthier than the Western diet. Following the paleo diet, however, can lead to nutritional deficiencies such as those of vitamin D and calcium, which in turn could lead to compromised bone health; it can also lead to an increased risk of ingesting toxins from high fish consumption.
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.
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.
A study published in the European Journal of Clinical Nutrition compared the benefits of following a Paleo diet versus a diet recommended by the American Diabetes Association in 24 participants with diabetes. After two weeks, researchers found that the Paleo diet led to greater improvements in blood sugar levels and insulin sensitivity than the conventional diabetes diet. (4)
The program was created by wife and husband Melissa Hartwig and Dallas Hartwig in 2009. They both became certified sports nutritionists; he worked as a physical therapist, and she was working at an insurance company during the day and doing nutritional consulting in her spare time. She quit her job to run the Whole30 business in 2010. They co-authored It Starts With Food (2012) and The Whole30: The 30-Day Guide to Total Health and Food Freedom (2015). They separated in 2015. Melissa Hartwig took over the business, and published Food Freedom Forever: Letting Go of Bad Habits, Guilt, and Anxiety Around Food in 2016.
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.
Deadly Harvest: The Intimate Relationship Between Our Health and Our Food by Geoff Bond. The author is a nutritional anthropologist who has for years investigated both foods of the past and our prehistoric eating habits. Using the latest scientific research and studies of primitive tribal lifestyles, Bond first explains the actual diet that our ancestors followed--a diet that was and still is in harmony with the human species. He then describes how the foods in today's diets disrupt our biochemistry and digestive system, leading to health disorders such as allergies, arthritis, cancer, diabetes, heart disease, osteoporosis, obesity, and more. Most important, he explains the appropriate measures we can take to avoid these diseases--and even beat them back--through healthy eating. The conclusions of Deadly Harvest are that disease control happens by eating a strict low-glycemic diet, lowering the percentage of body fat you carry around, eat a diet consisting of mostly non-starchy plant-based foods, eat a low-fat diet with ample amounts of omega-3 fats, maintain good colon health, engage in regular physical activity, get some daily sunshine, and reduce chronic stress. If you do this, then diseases like cancer, heart disease, digestive problems, allergies, autoimmune diseases, brain diseases, diabetes, and obesity can be avoided.

In 1995, as Glassman was burning the last of his bridges at local gyms, he got a call from a friend who worked at the sheriff's department in Santa Cruz. The department had heard about him and wanted him to train officers. Glassman, who was in the middle of a breakup with a longtime girlfriend, decided to go. He set up shop in a health center called Spa Fitness and taught his own brand of fitness training, which he had begun calling CrossFit, to officers and anyone else looking to buy 60 minutes of sweat.
The idea is that these are the foods that our bodies were designed to eat while many of the heavily processed modern foods that fill our diets today contribute to chronic disease and health problems. Proponents of the diet suggest that a well-planned Paleo diet could lead to improvements in many aspects of health, such as enhanced weight loss and reduced inflammation.
CrossFit gyms use equipment from multiple disciplines, including barbells, dumbbells, gymnastics rings, pull-up bars, jump ropes, kettlebells, medicine balls, plyo boxes, resistance bands, rowing machines, and various mats. CrossFit is focused on "constantly varied, high-intensity, functional movement," drawing on categories and exercises such as calisthenics, Olympic-style weightlifting, powerlifting, Strongman-type events, plyometrics, body weight exercises, indoor rowing, aerobic exercise, running, and swimming.
