Primal Body-Primal Mind: Beyond the Paleo Diet for Total Health and a Longer Life by Nora Gedgaudas advocates a diet that our paleo ancestors ate. Meat, lots of fat, and seasonal fruits and berries when available. Basically, sugar and starchy carbs are discouraged. You can download a chapter from the author's site. She has a Primal Body, Primal Mind Radio weekly show on Voice of America. It started May 20, 2009, so there are many shows you can listen to. Published June 30, 2011.
I started Week 1 feeling optimistic. This isn't hard at all! I told myself. Wrong. Days 2 and 3 hit, and the sugar withdrawal was so real. In my company's kitchen, I stared at the free M&Ms longingly. "All I can think about are gummy worms," I texted my work friends. Instead of eating candy, I scarfed down a banana with sunflower seed butter and felt slightly better.
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.
Update: So I just finished my first whole30 round and I have to say that I'm super excited by the results. When I hopped on the scale today, I noticed that I had lost 26.6 pounds. I then measured myself and noted that I lost a total of 31.5 inches (-5" from chest, -2" from right arm, -3.5" from left arm, -8" from waist, -5" from hips, -4" from right thigh, and -4" from left thigh). I am really excited by my results!
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.
The 2019 CrossFit Open reflects the growth of the international CrossFit community. National champions will be crowned through the Open and will qualify to compete in Madison. In the first few weeks of Open registrations, athletes from nearly 12,000 CrossFit affiliates worldwide have already signed up, the majority of which reside outside of the United States.
Richard Nikoley has the blog Free The Animal. He loves meat eating. His diet is near paleo, with the addition of some gray-area foods that he likes. These days most of his posts are on food. One recent trend in the paleo community is trying to optimize the proportions of the foods eaten. If you've read my definition you'll know that I simply define the diet as foods in and out. One of Richard's posts: Optimality: A Fool's Errand? has produced a long discussion of this trend.
But critics argue that the unlimited amount of red meat the paleo diet allows may have an adverse effect on heart health in people with diabetes, as research links eating red meat in excess to poor heart health. (11) If you have diabetes and don’t moderate your red-meat intake, this could be a big problem, as people with diabetes are 2 times as likely to die of heart disease as people who do not have diabetes.

The Paleo diet, also referred to as the caveman or Stone-Age diet, includes lean meats, fish, fruits, vegetables, nuts, and seeds. Proponents of the diet emphasize choosing low-glycemic fruits and vegetables. There is debate about several aspects of the Paleo diet: what foods actually existed at the time, the variation in diets depending on region (e.g., tropical vs. Arctic), how modern-day fruits and vegetables bear little resemblance to prehistoric wild versions, and disagreement among Paleo diet enthusiasts on what is included/excluded from the diet. Because of these differences, there is not one “true” Paleo diet.
“I can show up in workout tights and leg warmers (a-la Olivia Newton John), and all that the ‘bros’ I would normally be intimidated by care about is that my form is good and that I push myself as hard as I can,” adds Omar Sharif, Jr., grandson of the legendary film actor and a leading LGBT rights activist. “In other regular gyms, I felt a lot of body shame; I was constantly comparing myself to other more in-shape men. In CrossFit I don’t look in the mirror (there often aren’t any); I don’t care what I look like. None of us are there to look good, we’re there to encourage each other to get fit.”
Cordain explains that high intake of fruits and vegetables is one of best ways to reduce chances of cancer and heart disease. He notes that protein has twice the calorie burning effect of fat and carbs and is more satiating than both. He explains that starch, fats, sugars, and salts together cause us to keep eating. So if we limit our diet to fruits and vegetables and/or meat, we’ll stop eating when we’re full. And if you stop eating when you’re full, you’ll lose weight and won’t get fat. And as you lose weight, your cholesterol will improve (regardless of what you eat). This all makes sense and can’t really be disputed. If you want to lose weight, the Paleo diet will get you there and probably quickly. But Cordain’s hypothesis applied to long-term health falls short.
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.
During this program there is no calorie counting, no measuring, and no weighing yourself for the entire 30 days. I know that can be hard — especially if you’re feeling totally bloated (which can happen in the beginning) or particularly svelte in the later weeks. Just don’t do it. Even though a lot of people’s weight begins to normalize during the 30 days, the program focuses a lot on the “non-scale victories,” as in how you’re feeling. Is your sleep better? How’s your skin? Do you feel like doing cartwheels with that extra energy? Cool.
Exercise is a vital part of the live-by-your-genetic-code equation. Surviving in the Stone Age meant a constant on-the-go lifestyle that probably required 4,000-plus calories a day, according to David L. Katz, MD, director of the Yale University Prevention Research Center. Even most people who hit the gym regularly won't need to eat that many calories, but the principle of using food as fuel to exercise still stands.
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.
The paleo diet runs on the same foods our hunter-gather ancestors supposedly ate: fruits, vegetables, meats, seafood, and nuts. "By following these nutritional guidelines, we put our diet more in line with the evolutionary pressures that shaped our current genetics, which in turn positively influences health and well being," says Loren Cordain, PhD, professor of health and exercise science at Colorado State University and author of The Paleo Diet. He says the diet lessens the body's glycemic load, has a healthy ratio of saturated-to-unsaturated fatty acids, increases vitamin and nutrient consumption, and contains an optimal balance of protein, fat, and carbohydrates.
Diana Schwarzbein is another M.D. that has come to realize that low carb is what works. See reviews at The Schwarzbein Principle. The book is based on her work with insulin-resistant patients with Type II diabetes. She concludes that low-fat diets cause heart attacks, eating fat makes you lose body fat, and it's important to eat high-cholesterol foods every day.
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.
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.
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.
Eat generous amounts of saturated fats like coconut oil and butter or clarified butter. Beef tallow, lard and duck fat are also good, but only if they come from healthy and well-treated animals. Beef or lamb tallow is a better choice than lamb or duck fat. Olive, avocado and macadamia oil are also good fats to use in salads and to drizzle over food, but not for cooking. For more information, have a look at our beginner’s guide to Paleo and fat.
CrossFit, Inc. has also been criticized for having a "cavalier" attitude towards rhabdomyolysis by promoting a character known as "Uncle Rhabdo" (a cartoon clown dying in a dramatic fashion—hooked up to a dialysis machine, with his kidneys and intestines falling on the floor). In response to this criticism, Greg Glassman stated "We introduced (Uncle) Rhabdo because we're honest and believe that full disclosure of risk is the only ethical thing to do."
