Go heavy on the veggies. For example, at lunch and dinner, make them three quarters of your plate, with one quarter occupied by meat—instead of the other way around. If you’re okay with just Paleo-ish, you could even replace a few meat dishes each week with a plant-based meal that incorporates legumes or Greek yogurt (cue the fainting of Paleo purists).
Excluding foods. The exclusion of entire categories of commonly eaten foods like whole grains and dairy requires frequent label reading in the supermarket and in restaurants. It may also increase the risk of deficiencies such as calcium, vitamin D, and B vitamins, if these nutrients are not consistently eaten from the allowed foods or a vitamin supplement. For example, there are some nondairy calcium-rich foods that are absorbed well by the body such as collard and turnip greens or canned bone-in sardines and salmon, but you would have to eat five or more servings of these greens and fish bones daily to meet recommended calcium needs. (Note that some greens like spinach that are touted to be calcium-rich also contain oxalates and phytates that bind to calcium so very little is actually absorbed.) One small, short-term intervention study of healthy participants showed a 53% decrease from baseline in calcium intake after following a Paleo diet for three weeks.  Furthermore, the exclusion of whole grains can result in reduced consumption of beneficial nutrients such as fiber and thus may increase one’s risk for diabetes and heart disease.
CrossFit programming is decentralized, but its general methodology is used by thousands of private affiliated gyms, fire departments, law-enforcement agencies, and military organizations, including the Royal Danish Life Guards, as well as by some U.S. and Canadian high-school physical-education teachers, high-school and college sports teams, and the Miami Marlins.
Breakfast: My favorite breakfast during this program was leftovers from the night before — it was easy and usually had all the elements I needed to feel full and jumpstart my day. If there was leftover protein, I might throw it over some greens and make a salad. If there was soup, that was always perfect too. When I was feeling breakfast-y, eggs did the trick with some roasted veggies.
Paleo Pals: Jimmy and the Carrot Rocket Ship by Sarah Fragoso. Piper, Phoenix and Parker are not ordinary children–they are super heroes that travel the land helping other children learn about living the healthiest, most exciting, most super lives possible. They are known as The Paleo Pals, and this is a story about how they help out Jimmy, a little boy who is not sure if eating paleo food is even one tiny bit exciting or super.

“A CrossFit class can be the most extreme, strenuous, and mentally/physically exhausting workout you’ve ever done,” says Rick Palmisano a 30-year-old project manager from Orlando, Fla. “You build a lot of strong connections with the other athletes because you have to get through this grueling workout, together; the other CrossFitters not only become your opponents, but your family.” When Palmisano recently ruptured his Achilles tendon, for instance, he received gifts and get-well cards from his teammates.
At CrossFit, some coaches refer to this as “Uncle Rahbdo,” though it’s not something funny or enjoyable. You can read all about the condition and issues it can cause here. This typically occurs with (primarily male) ex-athletes who have not exercised for a while and come back trying to prove something, and end up working at a higher intensity than their body can handle.
Dr. Georgia Ede reviews the EAT-Lancet’s global nutrition study, “Food in the Anthropocene—the EAT-Lancet Commission on healthy diets from sustainable food systems,” which envisions a “Great Food Transformation” based on minimizing consumption of animal foods. She concludes, “the report fails to provide us with the clarity, transparency and responsible representation of the facts we need to place our trust in its authors. Instead, the Commission’s arguments are vague, inconsistent, unscientific, and downplay the serious risks to life and health posed by vegan diets.”
