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 following links tend towards news reports of scientific studies that point out some positive aspect of the paleo diet. If you are looking for current news reports, I suggest signing up for Google Alerts for the Type: News. I have three set up, for: "caveman diet," "paleo diet," and "paleolithic diet." You can also set them up for blogs and/or websites.


We have been lied to all our lives and told to eat plenty of whole grains and low fat. Grains have been genetically modified for so long and its effects on the human body have never been tested.

I didn't know the cravings could be stopped, I just assumed I had no will power. My Doctor recommended this diet and I can't thank him enough! If you follow this way of living you will never regret it so buy this book and improve you health now!

For the wall-ball, the athlete must start with the ball at a dead stop on the ground. The athlete may then pick up the ball and stand tall before beginning a set, or squat clean the ball, before beginning their first repetition of any set. An athlete may not start in a squat, pick up the ball from this position, and toss the ball to the target. A repetition consists of an athlete holding the ball in the “front rack,” and performing a full squat, hip-crease passing below the top of the knee, and when vertically extending throwing the ball to a specific target height. If the athlete’s hip does not break parallel, or the target does not touch the wall, that rep will not be counted. The athlete may then catch the ball and perform multiple reps if they so choose. Finally, athletes may not catch the ball on the bounce, and head right into a wall-ball repetition. The ball must be settled on the floor before picking it up to begin another set.
There is little argument over the health benefits of fruits and vegetables. They are chock-full of vitamins, minerals, fiber and antioxidants. The only caveat for paleo dieters is that some vegetables are starchy (e.g., potatoes) and some fruits are higher in sugar (e.g., bananas). So, if you are trying to lose weight or watch your blood sugar levels, eat these in moderation. In fact, potatoes are banned from some strict versions of the diet.

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)

Don’t even consider the possibility of a “slip.” Unless you physically tripped and your face landed in a pizza, there is no “slip.” You make a choice to eat something unhealthy. It is always a choice, so do not phrase it as if you had an accident. Commit to the program 100% for the full 30 days. Don’t give yourself an excuse to fail before you’ve even begun.
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]

Sweden's Staffan Lindeberg has a home page Paleolithic Diet in Medical Nutrition [archive.org]. A recent study of Staffan's has A Paleolithic diet improving glucose tolerance more than a Mediterranean-like diet in individuals with ischemic heart disease. Also see his first web page, an overview of his Kitava study: On the Benefits of Ancient Diets. Now he has a book Food and Western Disease: Health and nutrition from an evolutionary perspective. Here's a book review: Easy to Read, Informative, Packed with Footnotes on Studies.
Lutein/Zeaxanthin and Macular Health is an article discussing antioxidents and protection against the oxidizing ultraviolet radiation of the sun. The best dietary sources of antioxidants in general, and carotenoids specifically, are fruits and vegetables ­ and the more brightly colored, the better. Lutein and zeaxanthin are yellow pigments found in high concentrations in yellow fruits and vegetables as well as in dark green, leafy vegetables. In particular, spinach, kale and collard greens contain high levels of these two carotenoids.
The Great Cholesterol Con by Anthony Colpo. The definitive book on the non-dangers of dietary cholesterol and saturated fat was The Cholesterol Myths by Uffe Ravnskov, 2000. This book is six years newer. Its forward is by Uffe Ravnskov. To get a wonderful description of the book read the leading review at Amazon. The many reviews there average to 5 stars.
For example, although white potatoes were recorded as being available during the Paleolithic era, they are usually avoided on the Paleo diet because of their high glycemic index. Processed foods are also technically off limits due to an emphasis on fresh foods, but some Paleo diets allow frozen fruits and vegetables because the freezing process preserves most nutrients.
Greg Glassman has gone on record saying he wants the Games to reflect the international impact CrossFit is having. The current format doesn’t allow for that. If you remember the 2018 Games flag ceremony, only a handful of countries were represented. Even then, American flags (Canada included) were the overwhelming majority. BORING! Everyone knows CrossFit is an international sport and our main event should be represented as such. Good Job Glassman!
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?
Beginners to weight training – If you have NEVER weight trained before (or trained only on machines), CrossFit is a great place for you to start (provided you have a great coach, which I’ll cover shortly). You’ll learn how to do all of the important lifts in a super supportive and nonjudgmental environment. You might even find that…GASP…you love strength training!
The plan focuses on unprocessed foods and foods with very minimal, or, better yet, no added ingredients. Whole30 requires dieters to cut out a lot of items, including sugar, dairy and legumes, and then slowly reintroduce these food groups back into their diets after the 30 days. The purpose of the reintroduction phase is to see if any of the foods cut out are the culprit for any health issues.
Wheat Belly: Lose the Wheat, Lose the Weight, and Find Your Path Back to Health by William Davis, MD. A renowned cardiologist explains how eliminating wheat from our diets can prevent fat storage, shrink unsightly "wheat belly" bulges, and reverse myriad health problems, like minor rashes and high blood sugar. The author contends that every single human will experience health improvement by giving up modern wheat. The book provides readers with a user-friendly, step-by-step plan to navigate a new, wheat-free lifestyle. Informed by cutting-edge science and nutrition, along with case studies from men and women who have experienced life-changing transformations in their health after waving goodbye to wheat. The author's blog. Published August 30, 2011.
The theory is our bodies were designed, and still optimized, to eat what our Paleolithic ancestors ate. Like your hunger-gatherer forefathers, on Paleo you get all the meat from wild animals and unlimited fruits and vegetables you can eat. But no starchy vegetables (like potatoes), no legumes (like lentils or beans), no wheat, and no grains (like quinoa or corn) because those plants were invented by human beings during the agricultural revolution after our Paleolithic ancestors left the planet. You get one cheat day where you can eat whatever you want (“Occasional cheating and digressions may be just what you need to help you stick to the diet.”) No oil because it puts omega 6 and omega 3 ratios out of whack which should never exceed 2:1, except olive oil if you must. Dairy is also prohibited. And meat must come from animals that weren’t fed grains (like corn) because grains lead to inflammation and increased fat.

The CrossFit Games are the world’s premier test to find the Fittest on Earth™. They are world-renowned as a grueling test for the toughest athletes and a thrilling experience for spectators. Since its inception in 2007, the CrossFit Games have become “one of the fastest growing sports in America,” according to Forbes. The Games season is broken up into three stages. The first stage is the Open, the largest participatory sporting competition in the world. After the Open, top athletes from each of the 18 worldwide regions qualify for the second stage of competition—Regionals. Following Regionals, the top 40 men, 40 women and 40 teams move on to the final stage of competition: the CrossFit Games. The Games present the playing field where the fittest athletes are given a chance to distinguish themselves through consistently exceptional performances across broad time and modal domains. At the end of the competition, the Fittest on Earth are crowned™. To learn more, visit Games.CrossFit.com or Facebook.com/CrossFitGames.

Thank you for all of this. I’m going to give it a try. I’m trying to get rid of some added weight and more importantly I have GERD and can’t deal with the pain anymore. I’m completely overwhelmed by the side effects of the prescribed medication I was told to take. The cure sounds worse than the disease. You’ve taken all the stress of trying to figures all of this out off of me and that is truly appreciated. Thank you for all of your hard work. I look forward to starting week 1.
"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.
As with paleo, doing keto for more than a few weeks could lead to nutrient deficiencies according to Andy Yurechko, MS, RD, of Augusta University Medical Center in Georgia . He says lack of fiber is the biggest concern for keto fanatics, who may experience constipation. But it's possible to get fiber by eating lower-carb vegetables like broccoli and chia seeds.
Fresh fruits, fresh vegetables, fresh meat—the paleo diet is all about eating foods straight from the Earth just as our ancestors did. Those ancestors didn't have livestock or crops to call their own, so Cordain advises to go with grass-fed and organic varieties whenever possible to limit exposure to pesticides, antibiotics, and other chemicals that didn't exist back then. Research from Emory University suggests that Paleolithic people obtained about 35% of their calories from fats, 35% from carbohydrates, and 30% from protein.
I often get caught up in focusing on numbers and scales, so I decided not to officially weigh myself before or after Whole30. But I can attest that everything about my body just felt better. I know saying something like "I lost eleven pounds" would sound much more convincing, but I could see that my stomach was slimmer, as was my face (which is awkwardly the first place I gain weight).
A metaresearch group at Tilburg University in the Netherlands investigates scientists’ research methods and operations, scrutinizing questionable practices such as selective reporting of statistical tests and data massaging. The group instead advocates for practices such as preregistering studies and making experimental data immediately available for open external review and verification. Its members are optimistic that “the perverse incentives of careerist academia, to hoard data and sacrifice rigor for headline-generating findings, will ultimately be fixed.”
