For immediate weight loss, Paleo is a great and healthy solution. But after carefully reading and considering, I’m unconvinced that Paleo is optimal for long-term health. I think, in fact, it might lead to heart disease and other ills associated with heavy meat consumption. Although many of Cordain’s theories fall apart long-term, I thoroughly enjoyed the read and highly recommend the book. You should read critically and decide for yourself.

We also talked about our meals, our struggles, and the results we were seeing from Whole30. Mentally, I felt more clear-headed and emotionally stable. I slept deeper and remembered more of my dreams, something that tends to never happen. (In one dream, I accidentally ate a slice of pizza and cried about it because if you break your Whole30 diet, you're supposed to start again from Day 1.)
There’s been a lot of speculation around how the 2019 Games will pan out with the increased number of participants and elimination rounds. Details remain scarce at this time. The Alliant Energy Center confirmed those dates in an email as accurate. CrossFit HQ also said that is the correct weekend but that the actual start date has not been confirmed yet. Presumably because they’re still working out how the new format will affect timing.
The program was created by wife and husband Melissa Hartwig and Dallas Hartwig in 2009.[6] 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.[7] They co-authored It Starts With Food (2012) and The Whole30: The 30-Day Guide to Total Health and Food Freedom (2015).[8] They separated in 2015.[9] Melissa Hartwig took over the business,[7] and published Food Freedom Forever: Letting Go of Bad Habits, Guilt, and Anxiety Around Food in 2016.[10]
Both feeling hungry all the time and never feeling hungry are common on the Whole30 diet, especially during the first two weeks as your body adjusts to new sources of energy. Eventually, though, you shouldn’t feel those pangs since protein and fiber are filling, and you’ll get plenty of both. Plus, you’re allowed to eat as much as you want and add Whole30-compliant snacks to your meal plan, provided you truly are hungry. One small study of 29 participants published in Nutrition and Metabolism in 2010 found Paleo eaters (who have relatively similar diets to Whole30 followers) felt just as full but consumed fewer calories than their Mediterranean counterparts.
That's a lot of tension--doing everything possible to make CrossFit a mainstream sport while legally or digitally body slamming anyone who refers to the CrossFit name to cater to its athletes or fans. Glassman has always thrived on doing the opposite of what anyone has ever figured was sensible or possible. But now Glassman's own intentions, of doing what he wants and letting others do what they want, are pressing up against each other more every day. In CrossFit, Glassman is hoisting two massive, contending ideas at once: CrossFit is an open-source workout for everyone to enjoy; CrossFit is a trademarked brand protected as viciously as a Hells Angels jacket. If it comes clattering down, it will be painful as all hell to watch. But if it succeeds? It won't be the first time a CrossFitter shocks people with how much weight he put above his head. You can bet Glassman's gonna try for another rep.

Book-lovin’ Whole30 eaters should also pick up a copy of my New York Times bestselling cookbook, Nom Nom Paleo: Food for Humans, and my follow-up recipe book, Ready or Not! Both are packed with new and classic recipes—many of which can’t be found anywhere else. Plus, the vast majority of them are Whole30-compliant! Here’s a downloadable list of the 100+ Whole30 recipes in my first book, and here’s the Recipe Index in my second book, which identifies the 120+ Whole30 friendly dishes contained in its pages.

Vitamin D is the one supplement that would be paleo. At least it would be for those of us that don't live outside year round. You can have your D level measured. The low RDAs only prevent definable deficiences, not problems that take a long time to develop. Michael Holick, MD is a leading writer on this subject. This is a 10 page PDF: Vitamin D: importance in the prevention of cancers, type 1 diabetes, heart disease, and osteoporosis and its companion Sunlight and vitamin D for bone health and prevention of autoimmune diseases, cancers, and cardiovascular disease [change PDF to 100% to read]. Or if you prefer, there is an hour video on YouTube.
These are great! Thanks. I was wondering what your budget is for all this food. I seem to spend much more money for groceries when we are on whole 30. I try to shop at Costco and discount stores as I can, but it still seems like a lot. My shopping list I created for week one on my previous w30 was like $350 for a family of 5 (including food for one vegan). Is this normal?
Then I had my "aha!" moment. This was the perfect time to attempt Whole30, which I had always been interested in trying. My sister-in-law, Lisa, tried it a few years ago and she claims it changed her life. She ended up going off of the strict diet after 30 days, but stayed on the Paleo Diet. I asked her to be my "Whole30 advisor" throughout the entire process. (Side note: If you know someone who has done Whole30 before, ask them if they can be your guide!) Lisa was so helpful, I feel like I probably should have paid her.
A study published in the Journal of Strength and Conditioning Research entitled "Crossfit-based high intensity power training improves maximal aerobic fitness and body composition" followed 54 participants for 10 weeks of CrossFit training. The study said that "...a notable percentage of our subjects (16%) did not complete the training program and return for follow-up testing." The authors said "This may call into question the risk-benefit ratio for such extreme training programs..."[62] In 2014, CrossFit, Inc. filed a lawsuit against the National Strength and Conditioning Association for publishing this study, alleging that the data were false and were "intended to scare participants away from CrossFit."[63] The NSCA denies CrossFit, Inc.'s allegations[63] but has issued an erratum acknowledging that the injury data were incorrect.[64] In September 2016, the District Court ruled in favor of CrossFit Inc.'s claims that the injury data were found to be false, but not that the NSCA was commercially motivated or that the publishing of the study was defamatory as the NSCA no longer stood behind the study.[65] In February 2017, CrossFit filed for sanctions against the NSCA after one of the NSCA's witnesses admitted to falsifying statements during deposition.[66] In May 2017, the Court issued 17 issues sanctions against the NSCA, writing that the organization did have a commercial motive to falsify the data, had published the false data knowingly to disparage CrossFit, and had misled the public with their erratum.[66] CrossFit was awarded $74,000 in legal fees and allowed to continue investigating the NSCA. If the neutral-party analysis of the NSCA servers turns up any further misconduct, CrossFit may file an amended complaint for further sanctioning and compensation for lost revenue.[67]
In the long term, you have to be sure you’re getting calcium and other nutrients you’re missing by not having dairy products and certain grains. Some paleo-approved foods, such as salmon and spinach, contain calcium, so you have to be sure you’re including them in your diet. It would be a good idea to check with a registered dietitian, too, to make sure you’re meeting your calcium and other nutrient needs.
Fattening cattle with corn changes the lipid balance and is clearly not the natural diet for a grass eating cow. In Simple change in cattle diets could cut E. coli infection researchers have found that when cattle were fed hay or grass for just five days before slaughter, much less E. Coli cells were present in the animal's feces and virtually all surviving E. coli bacteria were not acid-resistant and were killed by human stomach acid.
As far as food goes, you’re simply going to eat a lot of fresh, good-quality eats and ditch the processed stuff. Beyond that, you’re removing all grains, dairy, soy, legumes, sugar, artificial sweeteners, and alcohol from your diet. All of these foods (especially in excess), according to the authors, have been linked to systemic inflammation, hormonal imbalance, gut issues, and more. The idea is to remove the stressors from your body and give it the nourishment and time to heal itself it needs. This means less inflammation, a healthy metabolism, hormonal harmony, a happy gut, clearer skin, and improved energy! Sounds good to me. (Although if we’re honest, I panicked a bit when I realized no cheese would hit my lips for a full month.)

The aspects of the paleo diet that advise eating fewer processed foods and less sugar and salt are consistent with mainstream advice about diet.[1] 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.[3][6] 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;[1][20] it can also lead to an increased risk of ingesting toxins from high fish consumption.[3]

After the Internet fitness community began talking about an Ohio State University study that described relatively high injury rates among CrossFitters, the Russes mobilized. They had Glassman's father, Jeffrey Glassman (now "chief scientist" at CrossFit), write a comprehensive rebuttal to the study for the CrossFit website. Berger called each and every research subject who had been reported as injured, to conclude that none actually were hurt, and then added an entire stammering Q&A with one of the paper's authors, kinesiology professor Steven Devor. Here's the kicker: The actual subject of the study was the great improvements in fitness the researchers found in CrossFit athletes. Aside from a handful of sentences, it was all positive.

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].
The data for Cordain's book only came from six contemporary hunter-gatherer groups, mainly living in marginal habitats.[36] One of the studies was on the !Kung, whose diet was recorded for a single month, and one was on the Inuit.[36][37][38] Due to these limitations, the book has been criticized as painting an incomplete picture of the diets of Paleolithic humans.[36] It has been noted that the rationale for the diet does not adequately account for the fact that, due to the pressures of artificial selection, most modern domesticated plants and animals differ drastically from their Paleolithic ancestors; likewise, their nutritional profiles are very different from their ancient counterparts. For example, wild almonds produce potentially fatal levels of cyanide, but this trait has been bred out of domesticated varieties using artificial selection. Many vegetables, such as broccoli, did not exist in the Paleolithic period; broccoli, cabbage, cauliflower, and kale are modern cultivars of the ancient species Brassica oleracea.[28]
An Interview with Ward Nicholson now has three parts on the web. Good overview of man's diet over the past 65 million years. Long but highly recommended reading. First published in Chet Day's "Health & Beyond" newsletter. Now part of a very comprehensive Beyond Vegetarianism site. Every argument that your vegetarian friends use to avoid meat for health reasons is debunked here.
A 2015 study in the Journal of the American College of Cardiology found that 76 people who followed the Paleo diet for 60 days (as well as those who followed vegan, Mediterranean and DASH plans for the same length of time) lost an average of 9 pounds and showed improvement in their blood pressure levels. The effects were greatest and most sustained among people who also attended regular diet support group meetings.
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. (12)
Certain food groups (like sugar, grains, dairy and legumes) could be having a negative impact on your health and fitness without you even realizing it. Are your energy levels inconsistent or non-existent? Do you have aches and pains that can’t be explained by over-use or injury? Are you having a hard time losing weight no matter how hard you try? Do you have some sort of condition, like skin issues, digestive ailments, seasonal allergies, or chronic pain, that medication hasn’t helped? These symptoms are often directly related to the foods you eat—even the “healthy” stuff. So how do you know if (and how) these foods are affecting you?

At CrossFit, some coaches refer to this as “Uncle Rahbdo,” though it’s not something funny or enjoyable. You can read all about the condition and issues it can cause here. This typically occurs with (primarily male) ex-athletes who have not exercised for a while and come back trying to prove something, and end up working at a higher intensity than their body can handle.


The Paleo Diet focuses on foods that are high in protein, low in carbs, and rich with fiber. There's a strong emphasis on meat, fruits, and vegetables — basically, anything our ancestors would have consumed more than 10,000 years ago during the Paleolithic era. (There's actually some truth to this: in July 2018, when researchers identified the stomach contents of the 5,300-year-old mummy Otzi, they found that his last meal was high-fat and contained "animal and plant remains," making it pretty Paleo-friendly.)

Trick And Treat - how 'healthy eating' is making us ill by Barry Groves. The author is one of the world's most outspoken proponents of a high-fat, low-carbohydrate diet. This book is an account of how and why the health-care establishment has got the concept of 'healthy eating' so wrong. Whereas Taubes work (see above) is a fairly straight forward review of the existing science, Groves expands into the politics of medical research and treatment to a much greater extent. "Trick and Treat" is divided into two parts. Part One describes the corruption in the health industry, points out the problems inherent in a high-carb, low-fat diet, and then prescribes a diet that leads to good health. The prescribed diet is high in fat - specifically animal fat, not polyunsaturated vegetable fat - and low in carbohydrates, with 60-70% of calories from fat, 15-25% of calories from protein, and a mere 10-15% of calories from carbohydrates. Part Two describes numerous diseases the author claims are the result of high carbohydrate consumption. These range from life-threatening disorders such as cardiovascular disease, diabetes, and cancer to less serious problems such as acne, near-sightedness and dental problems. The Amazon reviews average to 4+ stars.

Advocates of the diet argue that the increase in diseases of affluence after the dawn of agriculture was caused by changes in diet, but others have countered that it may be that pre-agricultural hunter-gatherers did not suffer from the diseases of affluence because they did not live long enough to develop them.[29] Based on the data from hunter-gatherer populations still in existence, it is estimated that at age 15, life expectancy was an additional 39 years, for a total expected age of 54 years.[30] At age 45, it is estimated that average life expectancy was an additional 19 years, for a total expected age of 64 years.[31][32] That is to say, in such societies, most deaths occurred in childhood or young adulthood; thus, the population of elderly – and the prevalence of diseases of affluence – was much reduced. Excessive food energy intake relative to energy expended, rather than the consumption of specific foods, is more likely to underlie the diseases of affluence. "The health concerns of the industrial world, where calorie-packed foods are readily available, stem not from deviations from a specific diet but from an imbalance between the energy humans consume and the energy humans spend."[33]

Obesity, heart disease, and diabetes: These are just a few of the health conditions that proponents of thePaleolithic diet, or caveman diet, blame on our sedentary lifestyles and modern diets, which are loaded with sugar, fat, and processed foods. Their proposed solution? Cut modern foods from our diet and return to the way our early hunter-gatherer ancestors ate.
The Stone Age Diet: Based on in-depth studies of human ecology and the diet of man by Walter L. Voegtlin. This was self-published back in 1975. Only a couple hundred copies were printed and distributed to friends and relatives. No one knew the book existed until some years later. In no way is he the father of the paleo diet. It is impossible to purchase. Apparently his descendents are planning a reprint, though the book is poorly written and not based upon factual anthropological information that even was available then. We have put up his Functional and Structural Comparison of Man's Digestive Tract with that of a Dog and Sheep. And a PDF can be found here.
The Paleo Answer: 7 Days to Lose Weight, Feel Great, Stay Young by Loren Cordain. The author shows you how to supercharge the Paleo diet for optimal lifelong health and weight loss. Featuring a new prescriptive 7-day plan and surprising revelations from the author's original research, it's the most powerful Paleo guide yet. Published December 20, 2011.
As of 2016 there are limited data on the metabolic effects on humans eating a paleo diet, but the data are based on clinical trials that have been too small to have a statistical significance sufficient to allow the drawing of generalizations.[3][6][20][not in citation given] These preliminary trials have found that participants eating a paleo nutrition pattern had better measures of cardiovascular and metabolic health than people eating a standard diet,[3][9] though the evidence is not strong enough to recommend the paleo diet for treatment of metabolic syndrome.[9] As of 2014 there was no evidence the paleo diet is effective in treating inflammatory bowel disease.[21]
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.

Following seven years in Carson, the Games moved to the Alliant Energy Center in Madison, Wisconsin, in 2017.[16] The next year, the qualifying Regionals were once again realigned due to increased competitiveness and popularity outside of Canada and the US.[17] 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.
Two years ago, I dropped 30 pounds (and kept it off) by doing the Whole30 and continuing to eat well in the months that followed. During the 30 days on the program, I lost 11 pounds. And for me, completing it helped me form healthy habits (like reading labels and not smothering everything in cheese), taught me how to cook an arsenal of healthy recipes I actually enjoyed eating and most importantly (and the reason why I do it every January), showed me how incredible my body feels when I'm not pumping it full of sugar and alcohol. These lessons stuck with me well past the 30 days, allowing me to drop an additional 19 pounds by April of that year and finally reach my goal weight.
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. [8] 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.

In 2007, the first annual CrossFit Games were contested in Aromas, California, on a small ranch owned by the family of Games director Dave Castro.[6] For the initial Games in 2007 and 2008, participation was open to anyone who made it to Aromas. The Games would also award an Affiliate Cup to the group from one CrossFit gym that had the best combined individual standings. In 2009, competitors had to qualify after over a hundred athletes had shown up in 2008. The athletes earned an invitation through either placing high enough in the previous year or through placing in the top worldwide in a set of qualifying events called Regionals hosted at a few CrossFit gyms. The CrossFit Games also added a separate set of team-based events for the Affiliate Cup, marking the first use of a designated Team Division, with teams of four (two men and two women).[7]
Eat WELL Feel GOOD: Practical Paleo Living by Diane Frampton has over 200 recipes that makes paleo eating simple, delicious, and ultimately, intuitive. So they claim. There are only a few reviews at Amazon. They all like the book, but their lack of details makes it appear that they are not truly independent reviews. The recipes have a Crossfit appeal to them. Chef Rachel Albert has made some of the recipes and posted here [archive.org].
A number of randomized clinical trials have compared the paleo diet to other eating plans, such as the Mediterranean Diet or the Diabetes Diet. Overall, these trials suggest that a paleo diet may provide some benefits when compared with diets of fruits, vegetables, lean meats, whole grains, legumes and low-fat dairy products. These benefits may include:
NeanderThin: Eat Like a Caveman to Achieve a Lean, Strong, Healthy Body (Hardcover) by Ray Audette, with Troy Gilchrist, was one of the early paleo diet authors. His home page NeanderThin [now restored from archive.org] has a diet based on the ideas of paleolithic nutrition. The diet can be followed as a low-carb, moderate or high carb diet, depending upon whether and how much fruit is used. You can read up through page 19 of the book at Google Books. The original press release from 1999. [The webmaster has an extra copy with the author's signature for sale. It has the original lime-purple cover. Pristine new condition. $60 (shipping included).

Adoption of the Paleolithic diet assumes that modern humans can reproduce the hunter-gatherer diet. Molecular biologist Marion Nestle argues that "knowledge of the relative proportions of animal and plant foods in the diets of early humans is circumstantial, incomplete, and debatable and that there are insufficient data to identify the composition of a genetically determined optimal diet. The evidence related to Paleolithic diets is best interpreted as supporting the idea that diets based largely on plant foods promote health and longevity, at least under conditions of food abundance and physical activity."[34] Ideas about Paleolithic diet and nutrition are at best hypothetical.[35]
Sugar is almost always manufactured and should be avoided on the paleo diet. This means you’ll need to cut out the delicious but destructive sweets and sugars that are standard in the Standard American Diet. The rule of thumb here is: if it contains a ton of sugar, it’s probably not on the paleo diet friendly. That said, here’s a specific lists of sweets that are not on the paleo diet food list. You might want to take a moment to say goodbye to them before you start your paleo diet journey.
Transformed cells adapt metabolism to support tumor initiation and progression. Specific metabolic activities can participate directly in the process of transformation or support the biological processes that enable tumor growth. Exploiting cancer metabolism for clinical benefit requires defining the pathways that are limiting for cancer progression and understanding the context specificity of metabolic preferences and liabilities in malignant cells. Progress toward answering these questions is providing new insight into cancer biology and can guide the more effective targeting of metabolism to help patients.
