"CrossFit is not a specialized fitness program, but a deliberate attempt to optimize physical competence in each of 10 recognized fitness domains," says founder Greg Glassman in the Foundations document. Those domains are cardiovascular and respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy.
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.
And again, there’s no concrete scientific proof that the paleo diet wards off disease, Sandon says. Any evidence of its benefits is anecdotal. Although some studies seem to support the benefits of the paleo diet, many scientists still believe we don’t yet have enough evidence to know whether the eating approach is totally healthy and without risk. “Nobody knows the long-term effects of this diet because no one has researched it to any degree,” Sandon says. It’s not really a new concept; instead it’s one that’s been recycled through the years, she adds.
We’re in a position to understand more of the benefits of the Paleo diet now that we have a basic understanding of which food sources are emphasized. One major benefit of the Paleo diet is an increased consumption of vitamins, minerals, antioxidants, and plant phytochemicals. Whole grains are not a good substitute for grass-produced or free-ranging meats, fruits, and veggies, as they contain no vitamin C, vitamin A, or vitamin B12. Many of the minerals and some of the B vitamins whole grains do contain are not absorbed efficiently by the body. The Paleo diet cuts out whole grains and replaces them with unprocessed, fresh foods.
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.
I wanted to love this book but it was a bit boring. There was too much detail on the athlete/event testing. "Well, I wanted them to do this, they did it. I liked the result, but I'll probably change it." I understand that the book was supposed to be like a daily journal but it didn't make for great reading. Obviously, putting the games together is a huge undertaking but the day to day pre-games testing of athletes and the results wasn't all that interesting. I did enjoy some of the behind the scenes stuff on the actual games.
We love nuts and they are decidedly paleo diet friendly. Be careful though, as cashews are high in fat and, for some reason, it’s incredibly easy to eat an entire jar of them in one sitting (that’s not just us, is it?). If you’re trying to lose weight, limit the amount of nuts you’re consuming. Otherwise, have at it. I mean, you can’t beat a good almond/pecan/walnut mix, can you?
Following seven years in Carson, the Games moved to the Alliant Energy Center in Madison, Wisconsin, in 2017. The next year, the qualifying Regionals were once again realigned due to increased competitiveness and popularity outside of Canada and the US. 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.
An early client of Glassman's described the CrossFit experience as "agony coupled with laughter." Glassman liked that. It was as if his increasingly fit posse had a subversive secret: combinations of exercises that seemed strange and reckless and maybe dangerous to the ignorant. When Elizer, who volunteered to build the website, asked Glassman if he had a logo in mind, Glassman thought about the idea of agony mixed with laughter, then thought about thumbing his nose at all the ho-hum personal trainers he had ever endured. He came up with a vomiting clown. He called it Uncle Pukie.
But the Paleo diet bans more than just highly processed junk foods—in its most traditional form, it prohibits any kind of food unavailable to stone age hunter–gatherers, including dairy rich in calcium, grains replete with fiber, and vitamins and legumes packed with protein. The rationale for such constraint—in fact the entire premise of the Paleo diet—is, at best, only half correct. Because the human body adapted to life in the stone age, Paleo dieters argue—and because our genetics and anatomy have changed very little since then, they say—we should emulate the diets of our Paleo predecessors as closely as possible in order to be healthy. Obesity, heart disease, diabetes, cancer and many other "modern" diseases, the reasoning goes, result primarily from the incompatibility of our stone age anatomy with our contemporary way of eating.
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.

The evolutionary discordance is incomplete, since it is based mainly on the genetic understanding of the human diet and a unique model of human ancestral diets, without taking into account the flexibility and variability of the human dietary behaviors over time. Studies of a variety of populations around the world show that humans can live healthily with a wide variety of diets, and that in fact, humans have evolved to be flexible eaters. Lactose tolerance is an example of how some humans have adapted to the introduction of dairy into their diet. While the introduction of grains, dairy, and legumes during the Neolithic revolution may have had some adverse effects on modern humans, if humans had not been nutritionally adaptable, these technological developments would have been dropped.
This episode of Inquiring Minds, a podcast hosted by best-selling author Chris Mooney and neuroscientist and musician Indre Viskontas, is guest-hosted by Cynthia Graber. It also features a discussion of the new popular physics book Trespassing on Einstein’s Lawn, by Amanda Gefter, and new research suggesting that the purpose of sleep is to clean cellular waste substances out of your brain.
CrossFit has been a full-on addiction for me. My lifestyle is so much better because of it. I eat better, feel better and look better. Every day I look forward to that hour or two after work where I can just hang out with my friends and let off some steam in a workout. The best part of this is that I get to have friendly competition with others, and most importantly myself.
According to the CDC, cardiovascular disease is the number one cause of death in the United States. Interestingly however, our Paleolithic ancestors and contemporarily studied hunter-gatherers showed virtually no heart attack or stroke while eating ancestral diets. The references below will explore these facts to better help you understand the heart-healthy benefits of a Paleo diet.
It's that time of year again, when all of your friends and family members are making resolutions to be healthier in 2019. Expect to see lots of the following on Instagram in the next month: #DryJanuary, #NewYearNewYou, #Whole30. And for anyone looking to try the latter, I applaud you — and I encourage you to do it. I decided to give the much-buzzed-about Whole30 diet a try last November.

That's the amount of time it takes for your body to reset and start the healing process, the authors say. It's also enough time to change your tastes and improve your relationship with food, so you naturally begin to prefer whole foods over their highly processed counterparts. After the 30 days are up, you're encouraged to slowly reintroduce the off-limits foods to see what works for you and what doesn't.
The trouble with that view, however, is that what they’re eating is probably nothing like the diet of hunter-gatherers, says Michael Pollan, author of a number of best-selling books on food and agriculture, including Cooked: A Natural History of Transformation. “I don’t think we really understand…well the proportions in the ancient diet,” argues Pollan on the latest episode of the Inquiring Minds podcast (stream below). “Most people who tell you with great confidence that this is what our ancestors ate—I think they’re kind of blowing smoke.”
The Dietitian's Guide to Eating Bugs by Daniel Calder is a comprehensive guide to the nutritional content of insects. He believes insect breeding and consumption are important elements sustainable living, particularly when it comes to complementing foraged plant material with meat products. Numerous insects contain nutrients similar to those found in more conventional livestock, except the feed to conversion ratio is much higher and they're much cheaper to breed. You can find the book at scribd. Also available in e-book format for $35.

The Amazon reviews average to 4+ stars.
A strict paleo diet does not allow dairy products because hunter-gatherers did not milk cows. Some paleo dieters say dairy is OK, especially if it is grass-fed because grass-fed butter, for example, has more omega-3s. Fermented dairy products are also OK for some paleo eaters because they have a lower content of lactose and casein, the two concerns paleo dieters have with dairy.
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.
One of the most straightforward ways to lose weight is to eat a bit less. Remembering that American portion sizes have ballooned as much as 138% in the past 50 years, cut down on your daily dose of food just a little, and whatever meal plan you choose can be a winner. A cut of chicken should fit in an imaginary deck of cards, and your serving of cheese should be about as big as three stacked dice.
Some Paleo dieters emphasize that they never believed in one true caveman lifestyle or diet and that—in the fashion of Sisson's Blueprint—they use our evolutionary past to form guidelines, not scripture. That strategy seems reasonably solid at first, but quickly disintegrates. Even though researchers know enough to make some generalizations about human diets in the Paleolithic with reasonable certainty, the details remain murky. Exactly what proportions of meat and vegetables did different hominid species eat in the Paleolithic? It's not clear. Just how far back were our ancestors eating grains and dairy? Perhaps far earlier than we initially thought. What we can say for certain is that in the Paleolithic, the human diet varied immensely by geography, season and opportunity. "We now know that humans have evolved not to subsist on a single, Paleolithic diet but to be flexible eaters, an insight that has important implications for the current debate over what people today should eat in order to be healthy," anthropologist William Leonard of Northwestern University wrote in Scientific American in 2002.
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.
I understand the concept of what they’re trying to say, but I feel awkward likening a lackluster cauliflower pizza to dry humping. We’re going to be practicing abstinence for those 30 days. In short, keep your pants on and don’t try to make pancakes. It’s too sexy. It might tempt you to take your pants off eventually and go full-pancake. I’m going to stop talking about taking my pants off now. Perfect.
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."
