The digestive abilities of anatomically modern humans, however, are different from those of Paleolithic humans, which undermines the diet's core premise. During the 2.6 million year-long Paleolithic era, the highly variable climate and worldwide spread of human populations meant that humans were, by necessity, nutritionally adaptable. Supporters of the diet mistakenly presuppose that human digestion has remained essentially unchanged over time.
"Every fad diet thinks it has discovered the root of all evil," says Dr. Ochner. But nutrients in legumes, whole grains, and dairy—all of which are forbidden on the paleo diet—can help to lower the risk of osteoporosis and cardiovascular disease, reduce blood pressure, and promote a healthy weight, he says. Cutting dairy, the primary source of calcium and vitamin D in modern diets, is especially worrisome for women who want to avoid osteoporosis.
Legumes are members of a large family of plants that have a seed or pod. This category includes all beans, peas, lentils, tofu and other soyfoods, and peanuts. Legumes are not allowed on paleo because of their high content of lectins and phytic acid. Similar to grains, this is a point of controversy in the scientific community. In fact, lots of research supports eating legumes as part of a healthy diet because they are low in fat and high in fiber, protein and iron.
Was I converted? Not really. I’ve always prefered to work out alone since I consider the gym “me” time. But having tried CrossFit once, I would try it again. Although I’ve never established any relationships at the gym, I’ve exhausted my patience with apps and bar culture. CrossFit, admittedly, seems like a good way to find someone who at least shares my interest in masochistic regimentation. I’m still pretty sure it’s a cult, though—just maybe one of the less harmful cults.
Nourishing Traditions: The Cookbook that Challenges Politically Correct Nutrition and the Diet Dictocrat by Mary G. Enig, Ph.D. and Sally Fallon. The premise is the culinary traditions of our ancestors, and the food choices and preparation techniques of healthy nonindustrialized peoples, should serve as the model for contemporary eating habits. However, they push whole grains and dairy, which aren't Paleolithic.
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. The Amazon reviews average to 5 stars.
You may lose weight on the Paleo Diet. If you build a “calorie deficit” into your Paleo plan – eating fewer calories than your daily recommended max or burning off extra by exercising – you should shed some pounds. How quickly and whether you keep them off is up to you. A 2015 review in the Journal of Gastrointestinal Liver Diseases concluded that a Paleo-esque diet “might be an acceptable antidote to the unhealthy Western diet, but only unequivocal results from randomized controlled trials or meta-analyses will support this hypothesis.” On that, we’re still waiting. In the meantime, here’s what has been found about the diet and others like it:
Participation and sponsorship have grown rapidly since the inception of the Games. The prize money awarded to each first-place male and female increased from $500 at the inaugural Games to $300,000 for 2019. The largest jump in prize money came from the first Games sponsored by Reebok in 2011 when first place went from $25,000 in 2010 to $250,000 in 2011. The total prize payout in 2016 was $2,200,000.
I personally struggle on a regular basis because I’m much more interested in heavy strength training than anything else – and I’m one of those people who really likes seeing very linear graphs and results to my training, and I do want to specialize. I have a very hard time creating workout plans because with CrossFit, you never know what’s coming next.
The Whole30 is not a diet, a weight-loss plan or quick fix – it’s designed to “change your life,” the founders say, by eliminating cravings, rebalancing hormones, curing digestive issues, improving medical conditions and boosting energy and immune function. The theory behind it is that all sorts of physical and mental health issues – ranging from acne to depression to allergies – could be due to your diet. But you can’t know which foods are to blame for what ails you unless you cut out all traces of sugar, alcohol, grains, dairy and legumes for 30 days. By day 31, you’ll be free from your food fog and may not even miss your nightly wine ritual or morning muffin fix. If and when you reintroduce food groups, your body’s reaction will tell you which foods you should continue to avoid – or at least limit.
Between 2009 and 2018, competitors qualified for the Games through participation at CrossFit Games regional events. For the 2019 Games, CrossFit, Inc. discontinued hosting the Regional qualifier and instead sanctioned independent fitness events as qualifiers separate from the Open. Most of the sanctioned events were already widely participated in by CrossFit Games athletes, often used as a part of off-season training, around the world. Each sanctioned event has its own rules for participation, but athletes that attend the sanctioned events are either by invite or through the event's qualification process.

A few days ago I was delighted to learn that Dr. Oz was going to again feature The Paleo Diet on his nationally syndicated television show along with one of my co-authors, Nell Stephenson, of The Paleo Diet Cookbook. I tuned into the Dr. Oz show and was happy about most of what I saw except for Chris Kresser, expounding upon the health virtues of a food group, beans and legumes, that definitely are not Paleo. Please read the following...
For most people the fact the Paleo diet delivers the best results is all they need. Improved blood lipids, weight loss, and reduced pain from autoimmunity is proof enough. Many people however are not satisfied with blindly following any recommendations, be they nutrition or exercise related. Some folks like to know WHY they are doing something. Fortunately, the Paleo diet has stood not only the test of time, but also the rigors of scientific scrutiny.
The Paleo Solution: The Original Human Diet by Robb Wolf, a research biochemist. Readers will understand digestion, how protein, carbohydrate and fat influence hormones, and how this plays into fat loss, health or disease. They'll understand the significance of dietary fats whether the concern is performance, health, longevity, or making your fanny look good in a bikini. The book goes into how lifestyle factors such as sleep and stress influence the hormone cortisol. It gets into basic blood work and what things people should ask their doctor to include to better assess inflammation and health. It also includes a detailed 30-day meal plan and a beginner exercise program. The exercise program is geared to the beginner or someone who is quite de-conditioned but the nutritional info would be helpful for anyone regardless of background. The author's website is Robb Wolf. He likes to pass out the information via weekly podcasts. Here's a video Introduction to the book. And here is an excerpt from the book: How to Keep Feces Out of Your Bloodstream (or Lose 10 Pounds in 14 Days). The many Amazon reviews all rave about the book. Published September 14, 2010.
The diet ranked last among 38 popular diets evaluated by U.S. News & World Report in its 2016 Best Diets Rankings; one of the raters, dietitian Meridan Zerner said: "We want behavioral changes and dietary changes that are slow and progressive and meaningful." David L. Katz said of the diet: "The grouping [of banned foods] is both random, and rather bizarre from a nutrition perspective. If the idea is good nutrition, cutting out whole grains and legumes is at odds with a boatload of evidence." It was selected as one of the worst health trends for 2013 by Health Magazine.
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.
Paleo Comfort Foods: Homestyle Cooking in a Gluten-Free Kitchen by Julie Sullivan Mayfield and Charles Mayfield.

Origins and Evolution of Human Diet was an academic web site at the University of Arkansas devoted to discussion of evolution and the human diet. They had good articles on the conferences link. Here is one from the archives: Boyd Eaton's Evolution, Diet and Health which argues that current w-6 : w-3 imbalance together with absolute dietary DHA intake quite low in human evolutionary perspective may be relevant to the frequency of unipolar depression.
You know that "no-makeup" makeup trend that requires TONS of makeup to make you look natural? Expect the same effect, but with no makeup whatsoever required, during and after Whole30. My skin was glowing the entire time I was on it. Strangers commented on my skin. While I still did have a hormonal breakout on my chin, it wasn't the spotty blemished mess it usually is. I feel like the tone, texture, and overall look of my skin was tip top.
“After recently moving to a new city, CrossFit has been by far the easiest place to meet people and make connections,” adds Jeff Lecky, a 39-year-old in finance and analytics from New Brunswick, Canada. “You’re surrounded by like-minded individuals with a passion for fitness and self-improvement, who typically have a similar lifestyle focused around health and fitness.”
Jan Engvald has studied food and health thoroughly in the literature. In Unexpected facts on... food he shows that today's health advice (more or less unchanged for more than 30 years) is a direct cause to the increase in national diseases like coronary heart disease, stroke, cancer, obesity, adult-onset diabetes, allergy, eye diseases, etc. His findings are low-carb and high-fat, close to paleo, though he allows high fat dairy.
Following seven years in Carson, the Games moved to the Alliant Energy Center in Madison, Wisconsin, in 2017. The next year, the qualifying Regionals were once again realigned due to increased competitiveness and popularity outside of Canada and the US. In 2018, there were nine Regionals hosted among 18 redefined regions with Europe increasing to three regions, Central America split from South America, while eliminating the Northern and Southern California regions.

Yet unlike other exercise trends, CrossFit exists as an entity unto itself. CrossFit is a lifestyle, a state of mind, and a reason for being. In an age of soul-sucking hookup apps and the waning popularity of gay bars, CrossFit provides a sense of community and kinship for gay men who feel deprived of it. Whether in small towns, big cities or traveling on the road, CrossFit is almost universally an LGBT “safe space.”
Go heavy on the veggies. For example, at lunch and dinner, make them three quarters of your plate, with one quarter occupied by meat—instead of the other way around. If you’re okay with just Paleo-ish, you could even replace a few meat dishes each week with a plant-based meal that incorporates legumes or Greek yogurt (cue the fainting of Paleo purists).
