CrossFit is a strength and conditioning program consisting mainly of a mix of aerobic exercise, calisthenics (body weight exercises), and Olympic weightlifting.[19] CrossFit, Inc. describes its strength and conditioning program as "constantly varied functional movements executed at high intensity across broad time and modal domains,"[20] with the stated goal of improving fitness, which it defines as "work capacity across broad time and modal domains."[21] Hour-long classes at affiliated gyms, or "boxes", typically include a warm-up, a skill development segment, the high-intensity "workout of the day" (or WOD), and a period of individual or group stretching. Some gyms also often have a strength-focused movement prior to the WOD. Performance on each WOD is often scored and/or ranked to encourage competition and to track individual progress. Some affiliates offer additional classes, such as Olympic weightlifting, which are not centered around a WOD.[22]
"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.
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?
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.
In William Calvin's The Ascent of Mind, Chapter 8 he discusses why he thinks that the Acheulian hand-ax (the oldest of the fancy stone tools of Homo erectus) was really a "killer frisbee." He argues that natural selection for throwing accuracy, which requires brain machinery, is the evolutionary scenario for bootstrapping higher intellectual functions. There are many more articles about evolution and human development throughout William's extensive site, though much of it these days is on climate change.

If you have more questions on specific foods, we’ve included a comprehensive list of paleo diet foods below. We’ve provided a list of the foods that are allowed on the paleo diet. We’ve also broken this list down into the specific food groups, so you can see which meats, vegetables, fruits, nuts, and fats are on the paleo diet. In addition to all of that, we’ve also included a comprehensive list of foods not allowed on the paleo diet.

Due to CrossFit's official partnership with Reebok, competitors at the 2015 Games were banned from wearing Nike footwear.[32] Nike arranged for several trucks to be parked near the main entrance to the arena, which served as mobile billboards with the slogan "Don't ban our shoe, beat our shoe".[33] The partnership also prohibits Nike from labeling its Metcon shoes as intended for CrossFit – the brand uses the term "high intensity training" instead.[32]

Your only job during the Whole30 is to focus on making good food choices. You don’t need to weigh or measure, you don’t need to count calories, you don’t need to purchase everything organic, grass-fed, pastured, or local. Just figure out how to stick to the Whole30 rules in any setting, around every special circumstance, under any amount of stress… for 30 straight days. Your only job? Eat. Good. Food.

So rather than a food-related reward for working so hard the last 30 days, why not reward yourself with something you’ve been wanting. This doesn’t have to be something tangible, just whatever you want. Personally, I would love to get some new clothes, food props, or go out on a (kidless) date with my husband. You get the idea, something that appeals to you but that isn’t food. We’re not dogs, we don’t need treats for good behavior.

Do not eat grains. This includes (but is not limited to) wheat, rye, barley, oats, corn, rice, millet, bulgur, sorghum, sprouted grains, and all gluten-free pseudo-cereals like quinoa, amaranth, and buckwheat. This also includes all the ways we add wheat, corn, and rice into our foods in the form of bran, germ, starch, and so on. Again, read your labels.
Still, many scientists have expressed concern that we do not yet have enough evidence to make any strong claims about the paleo diet’s health benefits, especially its long-term effects. In fact, in an article in response to the first review, authors Tanis R. Fenton and Carol J. Fenton, from the Cumming School of Medicine in Canada, wrote a letter to the editor in which they expressed their disappointment with the review. (5)
You’ll lose weight because any time you restrict entire food groups, your calorie intake tends to be lower, Sandon says. And whenever you burn more calories than you consume, you'll have weight loss, she says. (2) The focus on lean protein, fruits, and vegetables over calorie- and sodium-rich processed foods can also contribute to weight loss, though she also points out that the paleo diet wasn’t created to be a weight loss diet. (3)
The digestive abilities of anatomically modern humans, however, are different from those of Paleolithic humans, which undermines the diet's core premise.[4] 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.[4][5]
The premise behind "eating paleo" is that the current Western diet is contributing to the rise of chronic diseases such as obesity, heart disease and cancer. Paleo diet proponents claim, eating this way can reduce inflammation, improve workouts, increase energy, help with weight loss, stabilize blood sugar and even reduce the risk of chronic diseases.
Nourishing Traditions: The Cookbook that Challenges Politically Correct Nutrition and the Diet Dictocrat by Mary G. Enig, Ph.D. and Sally Fallon. The premise is the culinary traditions of our ancestors, and the food choices and preparation techniques of healthy nonindustrialized peoples, should serve as the model for contemporary eating habits. However, they push whole grains and dairy, which aren't Paleolithic.
"We settled, because I don't want to spent 50 to 75 grand getting sued," says Jason Janke. "I covered up the sign." Saran, CrossFit's general counsel, says it's all part of the fight against "the road to genericization." If people can sell "CrossFit equipment" the way they sell "baseball equipment," says Saran, then it becomes crossfit. Soon anyone will be able to coach crossfit or promote a crossfit tournament--effectively killing the value of being an official affiliate, or being CrossFit, for that matter.

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].
Most of these recipes give us enough dinner for our family and then leftovers for my husband and I (I make a separate lunch for the kids most times). If you both eat normal-sized portions, you would probably be fine to cut it in half and have enough for leftovers. But if you tend to eat larger portions, I’d err on the side of caution and just go with the full amount.
A homemade fixing for enchiladas, taco salad, tacos, or even burritos, this Whole30 recipe can be Bulletproof, too. Replace chicken broth with bone broth, then double-check your spices. It’s best to use fresh, high-quality spices and flavorings as much as possible so you can steer clear of any toxic mold. As always with Bulletproof, grass-fed beef is key.
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.”
