CrossFit is promoted as both a physical exercise philosophy and a competitive fitness sport, incorporating elements from high-intensity interval training, Olympic weightlifting, plyometrics, powerlifting, gymnastics, girevoy sport, calisthenics, strongman, and other exercises. It is practiced by members of over 13,000 affiliated gyms, roughly half of which are located in the United States, and by individuals who complete daily workouts (otherwise known as "WODs" or "workouts of the day"). CrossFit has been criticized for allegedly causing people to suffer from unnecessary injuries and exertional rhabdomyolysis.
Lastly, HAVE FUN. I believe strongly that the lifestyle changes that really “stick” are the ones that are fun and exciting. Continue to foster your culinary curiosity, and play around in the kitchen. Not only will you eat healthier, but you’ll develop skills and gain knowledge that’ll make you even more awesome than you are right now (as if that’s even possible).
Alcohol is a no-no if you are strict paleo. Beer is made from grains, and liquor also contains traces of gluten. But, good news for cider-lovers: most hard ciders are gluten-free, so they are allowed. Check the label to be sure. Red wine is more accepted in the paleo community because it contains the antioxidant resveratrol, but sorry chardonnay lovers, white wine is technically not allowed.
Overall, the diet is high in protein, moderate in fat (mainly from unsaturated fats), low-moderate in carbohydrate (specifically restricting high glycemic index carbohydrates), high in fiber, and low in sodium and refined sugars.  The monounsaturated and polyunsaturated fats (including the omega-3 fats EPA and DHA) come from marine fish, avocado, olive oil, and nuts and seeds.
Cordain argues that chimpanzees and horses avoid meat, and they have big bellies that we would have if we didn’t ditch plants for meat. He also says meat increased human brain size, and decreased stomach size so we can have the six-pack abs that chimps can’t. But I looked at his endnotes with citations to research and couldn’t find the source for these theories. I also couldn’t find research showing that legumes and grains were invented by humans.
We want you to be a part of our community. We want you to take this seriously, and see amazing results in unexpected areas.

Even if you don’t believe this will actually change your life, if you’re willing to give it 30 short days, DO IT. It is that important. We believe in it that much. It changed our lives, and we want it to change yours too.
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].
But then again, when have you found a program that is ENTIRELY ONLINE AND MOSTLY FREE that changes your life? When you are in line at the checkout with your meat and chicken thighs and raw almonds, remember the money you are going to save by NOT joining another weight-loss program or hiring a life coach or drinking booze or going to the doctor for that blood pressure you really ought to monitor which is quite possibly linked to your diet. Dallas and Melissa, the authors, say that a craving usually lasts about ten seconds. Count and breathe through the french fries someone raved about at the office. Skip out for a tiny walk while everyone is hoarding that cake at work. Eat a little roast turkey and some oven-baked potatoes. Read more books with the newfound energies. If I--a bon vivant of the kitchen, believe me, hoarder of butter, lover of booze, cream, sugar--can give these things up for thirty days, anyone can.
When the clock struck midnight, I couldn't wait any longer: I helped myself to a serving of plain white rice. I sat on my couch cross-legged, eating each spoonful with my eyes closed like one of the yogurt commercial ladies. I even smiled. The next day, I ate more gluten-free carbs, like rice and paleo pancakes. I also had wine and tequila, a grain-free liquor option. I didn't get bombed like I was worried about, but I did have a worse-than-usual hangover the next day. The fun night out was worth it, though.
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.
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.
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.
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.
Videos shot with a fisheye lens or similar lens may be rejected due to the visual distortion these lenses cause. If an athlete needs someone to adjust their camera during the WOD to capture all movements, this is acceptable, as long as the flow of the workout and the athlete is in view the whole time. It is the athletes responsibility to ensure their video meets the standard.
The Santa Cruz mornings and evenings became packed with fitness clients. The stretch of day in between grew into a time of study and reflection. He had a friend bring in printouts of fitness articles the friend had found using his newfangled Internet connection. "I went through thousands of pages like that," says Glassman. "When I finally got a computer, there was nothing on the Web on fitness I hadn't already seen."
Prior to starting, athletes should state their name, and show and state the weights and equipment to be used. All video submissions must be uncut and unedited in order to accurately display the performance. A clock or timer, with the running workout time clearly visible should be in the frame throughout the entire workout. Shoot the video from an angle so ALL exercises can be clearly seen meeting the movement standards. Videos shot with a fisheye lens or similar lens may be rejected due to the visual distortion these lenses cause. If an athlete needs someone to adjust their camera during the WOD to capture all movements, this is acceptable, as long as the flow of the workout and the athlete is in view the whole time.
On 4 June 2014, CrossFit uploaded a "parody video to their Facebook page" of Jesus, featuring concepts such as the "Holy Trinity of exercise". Yasmine Hafiz wrote in The Huffington Post that some "viewers are outraged at the disrespectful use of a Christian symbol", with one user asking "on what planet is it comical or encouraged to mock someones belief?"
If you're interested in the paleo plan but don't think you want to be so strict, you don't have to be all-or-nothing with your approach. Consider adopting some eating patterns from paleo and skipping the ones that don't work for you. For example, try just eating more fruits and vegetables and cutting down on added sugars. If you feel unsure about grains or dairy, talk to your doctor or a registered dietitian to determine what's best for your body.
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.
This list is going to be a little longer than the last. You cut out all sugar (both real and all substitutes whether natural or artificial, like honey, maple syrup, Splenda, etc.). No grains, legumes (including all forms of soy), dairy, or alcohol. You’re also told to avoid additives like MSG and carrageenan, although that should happen naturally if you’re sticking to whole foods.
Additionally, the Paleo diet puts a heavy emphasis on meat products. For this reason, the Paleo diet may not be suitable for everyone, and you’re unlikely to find a Paleo diet vegetarian or vegan modification out there. While meat in moderation is perfectly healthy, excessive meat consumption may not be. A high intake of red meat, for example, has been linked to an increased risk of mortality and colorectal cancer.

In one example, CrossFit, Inc.'s Twitter account posted a doctored illustration of a Coke advertisement, with "Open Happiness" replaced by "Open Diabetes". The image was paired with a quote from CrossFit CEO Greg Glassman that read "Make sure you pour out some for your dead homies." Controversy followed after singer Nick Jonas responded to the tweet, calling CrossFit, Inc.'s comments "ignorant". The company defended its tweet, stating that "Compelling statistical evidence supports CrossFit, Inc.'s campaign to prevent diabetes by raising awareness about its causes." When ABC News asked Greg Glassman to comment on the exchange, he replied "Fuck Nick Jonas. This is about the scourge of Type 2 Diabetes and its underlying causes. His sponsor, Coca-Cola, is a significant contributor to the diabetes epidemic both with product and 'marketing' spend."
