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.
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.
“I was drawn to CrossFit during my recovery from drug and alcohol abuse,” says Daniel Megson , a 32-year-old from Sydney, who founded WOD OUT to unite Australia’s gay CrossFitters.“I had lost so many friends from leaving the party scene behind; the hardest part was feeling isolated and lonely. CrossFit appeared to offer a new community of individuals living a healthier more active lifestyle. CrossFit saved my life!”
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.
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.
So what does the science say about the paleo diet? Some research suggests that the health claims hold truth. A review analyzed four randomized, controlled trials with 159 participants, and researchers found that the paleo diet led to more short-term improvements in some risk factors for chronic disease (including waist circumference and fasting blood sugar) compared with other control diets.

"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]
