“I think there are a lot of positives about it,” Holley says. “It cuts out a lot of processed foods just naturally, like processed grains or added sugar through soft drinks or juice.” And because the diet promotes eating anti-inflammatory foods — like fruits, vegetables, and unsaturated fats in nuts and certain oils — your health could benefit, Holley explains. Cutting out processed foods and sugar will also help lower your risk of certain diseases, like type 2 diabetes and certain cancers, she says. (6)
Similarly, any foods that were not easily available to Paleolithic humans are off-limits in this diet, Holley explains. That means processed foods — many of which contain added butter, margarine, and sugar — should not be a part of the paleo diet. The same goes for dairy, which may not have been accessible to Paleolithic humans, and legumes, which many proponents of the diet believe are not easily digestible by the body.
This understanding, coupled with the explosive worldwide growth of the sport, demands that CrossFit, Inc. reduce its share of the competitive CrossFit season. The best athletes, sponsors, and media entrepreneurs in the sport of fitness have recognized that the new Sanctionals model doesn’t diminish their opportunities—it expands them. There are more athletes competing in more CrossFit competitions in more places around the globe than ever. CrossFit, Inc. hasn’t abandoned the sport of fitness, it’s stewarding its longevity. 
Cordain admits that meat leads to plaque and increases cholesterol where plants wouldn’t. And science establishes that plaque and cholesterol lead to heart attacks and strokes. But Cordain argues that plaque alone is insufficient to cause harm. Rather, it is plaque combined with inflammation that causes heart attacks and strokes. So avoid acid, salt, legumes, wheat, starchy vegetables, dairy, oil, fatty meats, and grains because they cause inflammation. But if both science and Cordain agree that plaque is a necessary part of the heart-disease equation—and that meat causes plaque—why should we follow Paleo rather than just forgo meat?
Food in Antiquity: A Survey of the Diet of Early Peoples (Expanded Edition) by Don R. Brothwell and Patricia Brothwell is a survey of what is known archaeologically about food and drink in pre-modern times. The chapter on insects includes their food value. In beverages it covers what happens to a neglected jar of fruit juice. Under cannibalism it shows evidence of this being done in paleo times, thought most of the work focuses on the classical and near-eastern civilizations, but occasional mention is made of the mesoamerican cultures as well. There is taxonomic and anatomical information.

A great question to ask is “Does the Paleo diet work?” Here we have a head to head comparison between the Paleo diet and Mediterranean diet in insulin resistant Type 2 Diabetics. The results? The Paleo diet group REVERSED the signs and symptoms of insulin resistant, Type 2 diabetes. The Mediterranean diet showed little if any improvements. It is worth noting that the Mediterranean diet is generally held up by our government as “the diet to emulate” despite better alternatives. You can find an abstract and the complete paper here.


I cannot possibly put enough emphasis on this simple fact—the next 30 days will change your life. It will change the way you think about food. It will change your tastes. It will change your habits and your cravings. It will restore a healthy emotional relationship with food, and with your body. It has the potential to change the way you eat for the rest of your life. I know this because I did it, and millions of people have done it since, and it changed my life (and their lives) in a dramatic and permanent fashion.

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.
"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.[33]
