Get rid of the temptation – if you’re gonna go at this thing with a full head of steam, remove all the junk food from your house. It’s going to take a few weeks for your body to adjust to burning fat instead of glucose, and you might want to eat poorly here and there. If there’s no food in your house to tempt you, it will be much easier to stay on target.
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.
Due to CrossFit's official partnership with Reebok, competitors at the 2015 Games were banned from wearing Nike footwear. 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". The partnership also prohibits Nike from labeling its Metcon shoes as intended for CrossFit – the brand uses the term "high intensity training" instead.
Overall, my biggest Whole30 lesson is that mindful eating is possible. I don't have that urge to eat everything in sight, but I also know I don't need to deprive myself or worry about food 24/7. There's a happy medium where I get to decide what I really crave, weigh whether it's worth the bloat or restless sleep I might experience after eating it, and then say yes or no. I've caught myself thinking like this more, and so the ultimate goal of Whole30 has worked: I've changed my relationship with food—for the better.
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.
