In William Calvin's The Ascent of Mind, Chapter 8 he discusses why he thinks that the Acheulian hand-ax (the oldest of the fancy stone tools of Homo erectus) was really a "killer frisbee." He argues that natural selection for throwing accuracy, which requires brain machinery, is the evolutionary scenario for bootstrapping higher intellectual functions. There are many more articles about evolution and human development throughout William's extensive site, though much of it these days is on climate change.
CrossFit gyms use equipment from multiple disciplines, including barbells, dumbbells, gymnastics rings, pull-up bars, jump ropes, kettlebells, medicine balls, plyo boxes,[23] resistance bands, rowing machines, and various mats. CrossFit is focused on "constantly varied, high-intensity, functional movement,"[24] drawing on categories and exercises such as calisthenics,[25] Olympic-style weightlifting, powerlifting, Strongman-type events, plyometrics, body weight exercises, indoor rowing, aerobic exercise, running, and swimming.[26]
Update: So today is day 18 on my Whole30 journey. I just wanted to let you guys know that there is a lot of cooking involved with this program. I'm actually tired of cooking, which is why I started making large meals to freeze for the week. It actually works out well for me, especially since I don't mind eating the same food everyday. I've also been drinking a lot of tea and water. I feel like it is helping to flush out more toxins from my body. I has been approximately four days since my previous review and I lost an additional 2 pounds on this journey. I have so much energy that I actually am unable to sit still like I used to. I guess I was depressed before going on this journey so the Whole30 has actually improved my mood as well. I go for a walk every day and I've actually started a new workout program!

CrossFit, Inc. founder Greg Glassman overhauled the format for the 2019 games, replacing the Regionals with CrossFit-sanctioned international qualifying events.[18] As part of the changes, the 2019 games athletes qualify through being the top individual and team finishers from the sanctioned events, the top athlete from each country in the CrossFit Open, the top 20 overall finishers in the CrossFit Open, and four at-large athletes as chosen by CrossFit, Inc. Teams also no longer need to be created from one CrossFit-affiliated gym and can be formed from any four competitors.[19]
And she has a point: Many of the foods on the "no" list have nutritional benefits and can be a smart addition to a healthy diet. "Whole grains, beans and yogurt are really important for our gut health, yet on this diet, they are not allowed," says Brooke Zigler, RD. "By eliminating these food groups, people could be missing out on key nutrients in their diet."
It seems unlikely, from today's perspective, that a rudimentary site featuring a daily workout, a daily link to other fitness sites, and occasionally a photo of an athlete could generate a passionate viral following.But then you probably haven't tried a WOD. To a skeptical initiate, the commitment to the WOD seems odd: It might be just 10 minutes of alternating five reps of deadlifts with 100-yard sprints. Simple enough, you think, as you picture yourself running around like a beheaded, powerlifting chicken. (In conventional gyms, CrossFit workouts draw stares.) But when you actually do that workout, halfway through you hit the baptismal version of what early CrossFitters fondly called the mess-you-up moment--the recognition that there's devilish magic in this offbeat combination. In a few minutes, you're the sorest you've been in years. You're not sure you will survive. It's an adrenaline rush. For anyone bored with standard weights routines or the elliptical, it's addictive.
We Want to Live: The Primal Diet (2005 Expanded Edition) is a book by Aajonus Vonderplanitz. His basic philosophy is that (a) food is to be eaten in a live, raw condition; and (b) a diet rich in raw fats and raw meats from natural sources is essential to health. However his diet includes massive amounts of raw dairy. From the Planets is a book review by Ralph W. Moss. The Live-Food Mailing List discusses the concepts of this book.
For your body to enter ketosis, a good percentage of your calories (generally, somewhere between 60-80%, according to keto experts) needs to come from fats (this is why people frequently associate the Keto Diet with foods like bacon, even though most nutritionists say it's better to eat healthier items like avocados, nuts and seeds, eggs, and lean meats). The idea is that all of that fat-burning will help you lose weight, says Kizer.
Contrary to popular belief, fat doesn’t make you fat; carbs do (and the Standard American Diet contains a ton of them!). Natural oils and fats are your body’s preferred sources of creating energy, so it’s best to give your body what it’s asking for. The following are some of the best types of paleo diet oils and fats that you can give your body if you’re in need of some additional energy.
Cordain explains that high intake of fruits and vegetables is one of best ways to reduce chances of cancer and heart disease. He notes that protein has twice the calorie burning effect of fat and carbs and is more satiating than both. He explains that starch, fats, sugars, and salts together cause us to keep eating. So if we limit our diet to fruits and vegetables and/or meat, we’ll stop eating when we’re full. And if you stop eating when you’re full, you’ll lose weight and won’t get fat. And as you lose weight, your cholesterol will improve (regardless of what you eat). This all makes sense and can’t really be disputed. If you want to lose weight, the Paleo diet will get you there and probably quickly. But Cordain’s hypothesis applied to long-term health falls short.
The best part of CFA are the people! CrossFit has really changed my life and my perspective on so much. There are so many things that CrossFit and it’s community of people, especially the women, have taught me. I’ve finally found not only an outlet I was missing since my gymnastics days, but also a group of people who continually inspire me, support me and others, and are genuinely interested in seeing their peers meet goals. CrossFit has completely solidified my viewpoint that people and relationships matter most in life.

The idea is that these are the foods that our bodies were designed to eat while many of the heavily processed modern foods that fill our diets today contribute to chronic disease and health problems. Proponents of the diet suggest that a well-planned Paleo diet could lead to improvements in many aspects of health, such as enhanced weight loss and reduced inflammation.

This spring, Dr Cordain did an interview answering ten questions about the basics of The Paleo Diet®. To start your New Years out right, we wanted to share his answers with you. We hope you enjoy! - The Paleo Diet Team 1. The Paleo diet can be traced to a 1975 book by Walter Voegtlin, but, correct me if I’m wrong, you are responsible for bringing this diet to popularity in your 2002 book “The Paleo Diet.” Can you me about your...
This book was a surprise hit for me! I’ll be honest, I wasn’t expecting much, and only bought it because I was actually doing a Whole30 in January 2017 (it went great! I recommend it—I assume you’re thinking about it if you’re reading this review). We’ve been vegetarian for about 7 years, so eating and cooking so much meat, well, let’s just say I needed some help. The first thing I was impressed with? The recipes are very creative! They are easy to follow, don’t take a lot of time (I have a baby and a toddler and work from home), I particularly loved the slow-cooker recipes that make extra (beef roast, etc) that is then used for different recipes later in the week. Genius!

If you're interested in the paleo plan but don't think you want to be so strict, you don't have to be all-or-nothing with your approach. Consider adopting some eating patterns from paleo and skipping the ones that don't work for you. For example, try just eating more fruits and vegetables and cutting down on added sugars. If you feel unsure about grains or dairy, talk to your doctor or a registered dietitian to determine what's best for your body.


In 2011, the Games adopted an online qualification format, facilitating participation by athletes worldwide. During the five-week-long "CrossFit Open", one new workout is released each week. Athletes have several days to complete the workout and submit their scores online, with either a video or validation by a CrossFit affiliate. Since the Open is available to any level of athlete, many affiliates encourage member participation and the number of worldwide participants can be in the hundreds of thousands.[48]
