Like other fad diets, the Paleo diet is promoted as a way of improving health. There is some evidence that following this diet may lead to improvements in terms of body composition and metabolic effects compared with the typical Western diet or compared with diets recommended by national nutritional guidelines. There is no good evidence, however, that the diet helps with weight loss, other than through the normal mechanisms of calorie restriction. Following the Paleo diet can lead to an inadequate calcium intake, and side effects can include weakness, diarrhea, and headaches.
By the second week I started to notice that my face and my stomach looked less puffy. Score! I saw this as a sign that inflammation in my system was going down. One of the most remarkable changes was in my mood. I felt generally happy and positive. I would say I’m a positive person in general, but I do get stressed out easily. The margin for getting really stressed got a little thicker, and I was simply able to deal better.
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.)
He also makes a concerted effort to avoid new streams of revenue. (See "CrossFit Doesn't Want Your Money.") CrossFit makes most of its money from training seminars: Every weekend, it certifies hundreds of people as trainers, at $1,000 a pop. It also collects registration fees for the CrossFit Games, royalties from Reebok for CrossFit apparel, and annual affiliate fees. The affiliate fees, which top out at $3,000 a year, are locked in at their original rates. Joshua Newman, who runs a big, successful box called CrossFit NYC, told me he pays just $500 a year.
No background science here or lengthy explanations, only 15 easy guidelines to follow to kick-start your Paleo journey. It’s up to you to decide to what extent you want to follow those guidelines, but if you follow them 100% you can be assured that you are eating the best food for your body and greatly investing in your long term health and well-being.
The "CrossFit Games", directed by Dave Castro, have been held every summer since 2007. Athletes at the Games compete in workouts they learn about only hours beforehand, sometimes including surprise elements that are not part of the typical CrossFit regimen. Past examples include a rough-water swim, a softball throw, and a pegboard climb. The Games are styled as a venue for determining the "Fittest on Earth," where competitors should be "ready for anything."
