Another downside: If you have had chronic health issues (especially gut related), you may find that reintroduction actually teaches you that you're sensitive to most foods. It turns out peanut butter, gluten, and most dairy are now off limits. That rots!! But I'll live. I feel so, so much better without them, as I learned. And wouldn't you rather know why you feel crappy all the time?
Of course Wikipedia has a page on the Paleolithic Diet. It is quite thorough. It also isn't clear about the lean/fatty meat debate between the followers of Loren Cordain and a slew of others, and pushes lean meat. It is weak on the variations of the diet. Then it restricts fermented beverages. Even butterflies eat fermented fruit. Why wouldn't our paleo ancestors also?
I wrote a book called The Paleo Solution which went on to become a New York Times Bestseller. This book incorporates the latest, cutting edge research from genetics, biochemistry and anthropology to help you look, feel and perform your best. I am a research biochemist who traded in his lab coat and pocket protector for a whistle and a stopwatch to become one of the most sought after strength and conditioning coaches in the world. With my unique perspective as both scientist and coach you will learn how simple nutrition, exercise and lifestyle changes can radically change your appearance and health for the better.
Here comes the tough love. This is for those of you who are considering taking on this life-changing month, but aren’t sure you can actually pull it off, cheat free, for a full 30 days. This is for the people who have tried this before, but who “slipped” or “fell off the wagon” or “just HAD to eat (fill in food here) because of this (fill in event here).” This is for you.
The biggest downside of this diet is how restrictive it is. A month is a pretty long stretch to make it without taking bite of quinoa, popping a chickpea, or sneaking a sip of wine (especially if you’re a busy, social person), and the protocol does not allow for even the smallest of slip-ups. From the manual: “One bite of pizza, one spoonful of ice cream, one lick of the spoon mixing the batter within the 30-day period and you’ve broken the “reset” button, requiring you to start over again on Day 1.” (Yikes!)
The only way this works is if you give it the full thirty days: no cheats, slips, or “special occasions.” This isn’t a hazing, a boot camp, or us playing the tough guy. This is a fact, born of science and experience. The Whole30 is, at its heart, an elimination diet. Just a small amount of any of these inflammatory foods could break the healing cycle; promoting cravings, messing with blood sugar, disrupting the integrity of your digestive tract, and (most important) firing up the immune system. One bite of pizza, one spoonful of ice cream, one lick of the spoon mixing the batter within the 30-day period and you’ve broken the “reset” button, requiring you to start over again on Day 1.
CrossFit is a strength and conditioning program consisting mainly of a mix of aerobic exercise, calisthenics (body weight exercises), and Olympic weightlifting. CrossFit, Inc. describes its strength and conditioning program as "constantly varied functional movements executed at high intensity across broad time and modal domains," with the stated goal of improving fitness, which it defines as "work capacity across broad time and modal domains." 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.
