The CrossFit Games is an athletic competition sponsored by Crossfit Inc. and Reebok. The competition has been held every summer since 2007. Athletes at the Games compete in workouts that they learn about hours or days beforehand, consisting mostly of an assortment of standard aerobic, weightlifting, and gymnastics movements, as well as some additional surprise elements that are not part of the typical CrossFit regimen such as obstacle courses, ocean swimming, softball throwing, or ascending a pegboard. The CrossFit Games stylizes their individual winners as the "Fittest on Earth".
And again, there’s no concrete scientific proof that the paleo diet wards off disease, Sandon says. Any evidence of its benefits is anecdotal. Although some studies seem to support the benefits of the paleo diet, many scientists still believe we don’t yet have enough evidence to know whether the eating approach is totally healthy and without risk. “Nobody knows the long-term effects of this diet because no one has researched it to any degree,” Sandon says. It’s not really a new concept; instead it’s one that’s been recycled through the years, she adds.
Update: So I just finished Day 23 of my Whole30 Journey and I feel good, aside from the fact that I caught a cold. Weighing myself today, I discovered that I lost 19.5 pounds so far! I measured myself and immediately noted that I lost 19 inches over all (I measure my chest, both arms, both legs, waist, and hips). I think when I am done with my first round, I'll take a day off then start a second round. I just feel that great overall.
Meetup has a growing number of paleo groups, now numbering in the dozens. Each has a local message board. They have a map of Paleo Diet Meetups around the world. Initially I tried listing them all here. The number grew and Meetup wasn't letting me find groups in newest order, except for my zip code. You now have to go there to find the one nearest you.
An early client of Glassman's described the CrossFit experience as "agony coupled with laughter." Glassman liked that. It was as if his increasingly fit posse had a subversive secret: combinations of exercises that seemed strange and reckless and maybe dangerous to the ignorant. When Elizer, who volunteered to build the website, asked Glassman if he had a logo in mind, Glassman thought about the idea of agony mixed with laughter, then thought about thumbing his nose at all the ho-hum personal trainers he had ever endured. He came up with a vomiting clown. He called it Uncle Pukie.
As far as food goes, you’re simply going to eat a lot of fresh, good-quality eats and ditch the processed stuff. Beyond that, you’re removing all grains, dairy, soy, legumes, sugar, artificial sweeteners, and alcohol from your diet. All of these foods (especially in excess), according to the authors, have been linked to systemic inflammation, hormonal imbalance, gut issues, and more. The idea is to remove the stressors from your body and give it the nourishment and time to heal itself it needs. This means less inflammation, a healthy metabolism, hormonal harmony, a happy gut, clearer skin, and improved energy! Sounds good to me. (Although if we’re honest, I panicked a bit when I realized no cheese would hit my lips for a full month.)
After spending a week fine-tuning my new eating plan, I decided to add workouts back into my routine. On a typical week, I'll go to a cardio or strength class (I like boxing) once or twice and do some yoga or stretching at home another night. I dove right in and hit up my favorite boxing studio, Rumble. But I was really nervous. What if I didn't have enough energy? What if I passed out during class? What if I got so hungry I caved and bought a slice of pizza on the walk home from class?
We also talked about our meals, our struggles, and the results we were seeing from Whole30. Mentally, I felt more clear-headed and emotionally stable. I slept deeper and remembered more of my dreams, something that tends to never happen. (In one dream, I accidentally ate a slice of pizza and cried about it because if you break your Whole30 diet, you're supposed to start again from Day 1.)
Sweden's Staffan Lindeberg has a home page Paleolithic Diet in Medical Nutrition [archive.org]. A recent study of Staffan's has A Paleolithic diet improving glucose tolerance more than a Mediterranean-like diet in individuals with ischemic heart disease. Also see his first web page, an overview of his Kitava study: On the Benefits of Ancient Diets. Now he has a book Food and Western Disease: Health and nutrition from an evolutionary perspective. Here's a book review: Easy to Read, Informative, Packed with Footnotes on Studies.
CrossFit is promoted as both a physical exercise philosophy and a competitive fitness sport, incorporating elements from high-intensity interval training, Olympic weightlifting, plyometrics, powerlifting, gymnastics, girevoy sport, calisthenics, strongman, and other exercises. It is practiced by members of over 13,000 affiliated gyms, roughly half of which are located in the United States, and by individuals who complete daily workouts (otherwise known as "WODs" or "workouts of the day"). CrossFit has been criticized for allegedly causing people to suffer from unnecessary injuries and exertional rhabdomyolysis.
