The paleo diet is promoted as a way of improving health. There is some evidence that following this diet may lead to improvements in terms of body composition and metabolic effects compared with the typical Western diet or compared with diets recommended by national nutritional guidelines. There is no good evidence that the diet helps with weight loss, other than through the normal mechanisms of calorie restriction. Following the paleo diet can lead to nutritional deficiencies such as an inadequate calcium intake, and side effects can include weakness, diarrhea, and headaches.
While gorging on cheese and bread post–Whole30 sounds fun, it's not the way you're supposed to end the elimination diet. Instead, you want to slowly reintroduce certain food groups to see how each individually affects your body and mind. I decided to go this route because I was interested in discovering food sensitivities. And frankly, I was afraid of puking the second I came into contact with dairy or alcohol.
Paleo diets are based on a simple premise – if the cavemen didn’t eat it, you shouldn’t either. So long to refined sugar, dairy, legumes and grains (this is pre-agricultural revolution), and hello to meat, fish, poultry, fruits and veggies. The idea is that by eliminating modern-era foods like highly-processed carbs and dairy, you can avoid or control “diseases of civilization” like Type 2 diabetes and heart disease, and likely lose weight too. What you eat and how much depend on your goals or the specific program you’re on, if you choose to follow one. The high-protein diet is ranked poorly among U.S. News experts, who consider it too restrictive to be healthy or sustainable.
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.
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."
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.
In my first CrossFit experience three years ago, I almost made myself puke because I wanted so badly to finish with a good time. Last year, I did another CrossFit workout that I hadn’t properly prepared for and cranked out 100 pull ups quickly…and I ended up walking around with T-rex arms for a WEEK because I physically could not straighten them. Not kidding.
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.

This 2003 CrossFit Journal article captures an early conception of a universal, multi-event test of fitness that laid the foundation for CrossFit competition, including what would become the CrossFit Open and the CrossFit Games. The design requirements for such a test "included but were not limited to the following: quantifiable results; consistency with the CrossFit fitness concept; raising our commitment to improving absolute strength, relative strength, and gymnastic foundations; balancing intrinsic abilities of smaller and larger athletes; emphasizing exercises critical to and foundational to advanced training; mixing training demands within each test and, of course, over the total competition; a design that would identify an athlete’s weaknesses and possibly stand as a workout plan for improving overall fitness; and, finally, we wanted to design a competition that would be 'hard as hell.'"
