We cannot time travel and join our Paleo ancestors by the campfire as they prepare to eat; likewise, shards of ancient pottery and fossilized teeth can tell us only so much. If we compare the diets of so-called modern hunter-gatherers, however, we see just how difficult it is to find meaningful commonalities and extract useful dietary guidelines from their disparate lives (see infographic). Which hunter–gatherer tribe are we supposed to mimic, exactly? How do we reconcile the Inuit diet—mostly the flesh of sea mammals—with the more varied plant and land animal diet of the Hadza or !Kung? Chucking the many different hunter–gather diets into a blender to come up with some kind of quintessential smoothie is a little ridiculous. "Too often modern health problems are portrayed as the result of eating 'bad' foods that are departures from the natural human diet…This is a fundamentally flawed approach to assessing human nutritional needs," Leonard wrote. "Our species was not designed to subsist on a single, optimal diet. What is remarkable about human beings is the extraordinary variety of what we eat. We have been able to thrive in almost every ecosystem on the Earth, consuming diets ranging from almost all animal foods among populations of the Arctic to primarily tubers and cereal grains among populations in the high Andes.”
The Carnitine Miracle by Robert Crayhon, M.S. The nutrient carnitine is abundant in red meat. According to Crayhon carnitine helps balance blood lipids and blood sugar levels, maximizes energy levels, increases endurance, eliminates discomfort in ketosis, promotes burning of fat and building of muscle and increases overall well-being.

Oh sleep, it's one of my favorite things in the world, yet it has always been a real challenge for me. I have been on and off of sleep medication for seven years. For me, the hardest part is actually falling asleep. Well on Whole30 I fell asleep naturally. The first few days, I would be so exhausted by bedtime that I would fall asleep as soon as my head hit the pillow, and that continued the whole month. This was probably the most drastic and exciting change that I experienced on Whole30.

After the Internet fitness community began talking about an Ohio State University study that described relatively high injury rates among CrossFitters, the Russes mobilized. They had Glassman's father, Jeffrey Glassman (now "chief scientist" at CrossFit), write a comprehensive rebuttal to the study for the CrossFit website. Berger called each and every research subject who had been reported as injured, to conclude that none actually were hurt, and then added an entire stammering Q&A with one of the paper's authors, kinesiology professor Steven Devor. Here's the kicker: The actual subject of the study was the great improvements in fitness the researchers found in CrossFit athletes. Aside from a handful of sentences, it was all positive.
Whole30 is a nutritional program designed to change the way you feel and eat in 30 days. Basically, you have to remove all of the potentially inflammatory foods and beverages in your diet (think: added sugar and sweeteners, alcohol, grains, legumes, dairy, processed foods and beverages, baked goods, and junk foods) and eat three "clean" meals a day, made with Whole30-approved ingredients (think: meats, seafood, veggies, and eggs).
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.

Our bodies need much more protein than the average person consumes. In fact, protein accounts for only 15 percent of the average person’s daily calories, while 19 to 35 percent of the average hunter-gatherer diet was comprised of protein. This was due to the high consumption of meat, seafood, and other animal products prevalent in contemporary approaches to Paleo eating.
The Stone Age Diet: Based on in-depth studies of human ecology and the diet of man by Walter L. Voegtlin. This was self-published back in 1975. Only a couple hundred copies were printed and distributed to friends and relatives. No one knew the book existed until some years later. In no way is he the father of the paleo diet. It is impossible to purchase. Apparently his descendents are planning a reprint, though the book is poorly written and not based upon factual anthropological information that even was available then. We have put up his Functional and Structural Comparison of Man's Digestive Tract with that of a Dog and Sheep. And a PDF can be found here.
We love nuts and they are decidedly paleo diet friendly. Be careful though, as cashews are high in fat and, for some reason, it’s incredibly easy to eat an entire jar of them in one sitting (that’s not just us, is it?). If you’re trying to lose weight, limit the amount of nuts you’re consuming. Otherwise, have at it. I mean, you can’t beat a good almond/pecan/walnut mix, can you?
You know that "no-makeup" makeup trend that requires TONS of makeup to make you look natural? Expect the same effect, but with no makeup whatsoever required, during and after Whole30. My skin was glowing the entire time I was on it. Strangers commented on my skin. While I still did have a hormonal breakout on my chin, it wasn't the spotty blemished mess it usually is. I feel like the tone, texture, and overall look of my skin was tip top.
So what does the science say about the paleo diet? Some research suggests that the health claims hold truth. A review analyzed four randomized, controlled trials with 159 participants, and researchers found that the paleo diet led to more short-term improvements in some risk factors for chronic disease (including waist circumference and fasting blood sugar) compared with other control diets.

No cheating, kids. Hartwig emphasizes the importance of sticking to this plan with zero slip-ups, so you give your body the complete break (from not-so-healthy food) it deserves. If life happens and a glass of wine or a piece of bread gets in the way, Hartwig recommends starting over. She wants you to feel the full benefits of the entire 30 days. We're not gonna lie: We've let a glass of wine slip before, we didn't start over, and still felt on top of the world at the end. (We aren't suggesting you do the same, but we're just being real with you.) For a full list of rules, visit Whole30.com.
Fruits are not only delicious, but they’re also great for you. That said, fruits (even paleo-approved ones) contain large amounts of fructose which, while much better than HFCS (high-fructose corn syrup), is still sugar. If you’re looking to lose weight on the paleo diet, you’ll want to cut back on your fruit intake and focus more on the vegetables allowed on the paleo diet. However, feel free to have one to three servings of fruit a day. Check out this list of paleo diet fruits and see if you’re not hungry by the end! (We’ll admit, we’re partial to blackberries!)
The CrossFit Games determine the Fittest on Earth. The process of finding these elite athletes is not simply a matter of jotting down some movements on a piece of a paper. Nor is it random, although the best athletes are prepared for any physical challenge. The purpose of this book is to chronicle the process used to develop and refine the events that tested the best athletes in the world in 2017. Dave Castro, Director of the CrossFit Games, will take you from the early stages of the season to the end of the final event in Madison, and he’ll share detailed thoughts on every aspect of the competition, including the workouts of the Open and Regional rounds. In 2017, this is how Castro constructed the tests that defined the CrossFit Games and determined the Fittest on Earth.

While founders Dallas Hartwig and Melissa Hartwig are adamant in their book and on their website that “you’ve done harder things than this, and you have no excuse not to complete the program as written,” the Whole30 is not for the lazy or noncommittal. Without careful planning, a strong support system and dogged dedication, a business lunch, flight delay or date night can throw you off and send you back to the start. By nature, diets that eliminate entire food groups are tough to follow. On the other hand, it’s only 30 days.
The China Study is frequently cited when criticizing the Paleo Diet – focusing on a vegetarian diet and consuming rice is healthier than the Paleo Diet. I respectfully disagree with that nutritional philosophy and strongly disagree with the conclusions drawn from that book [7], and will leave you to make your own conclusions based on your own self-experimentation.
As University of California-Davis food chemist Bruce German told Pollan in an interview, “You could not survive on wheat flour. But you can survive on bread.” Microbes start to digest the grains, breaking them down in ways that free up more of the healthful parts. If bread is compared to another method of cooking flour—basically making it into porridge—”bread is dramatically more nutritious,” says Pollan.
Proponents of the Paleo diet follow a nutritional plan based on the eating habits of our ancestors in the Paleolithic period, between 2.5 million and 10,000 years ago. Before agriculture and industry, humans presumably lived as hunter–gatherers: picking berry after berry off of bushes; digging up tumescent tubers; chasing mammals to the point of exhaustion; scavenging meat, fat and organs from animals that larger predators had killed; and eventually learning to fish with lines and hooks and hunt with spears, nets, bows and arrows.
According to Adrienne Rose Johnson, the idea that the primitive diet was superior to current dietary habits dates back to the 1890s with such writers as Dr. Emmet Densmore and Dr. John Harvey Kellogg. Densmore proclaimed that "bread is the staff of death," while Kellogg supported a diet of starchy and grain-based foods.[11] The idea of a Paleolithic diet can be traced to a 1975 book by gastroenterologist Walter Voegtlin,[7]:41 which in 1985 was further developed by Stanley Boyd Eaton and Melvin Konner, and popularized by Loren Cordain in his 2002 book The Paleo Diet.[8] The terms caveman diet and stone-age diet are also used,[12] as is Paleo Diet, trademarked by Cordain.[13]

#1) If you’re not careful, this type of diet can get expensive. But as we know, with a little research, we can make eating healthy incredibly affordable. Admittedly, while I recommend eating organic fruits and veggies, free range chicken, and grass-fed beef whenever possible, these products can be a bit more expensive in conventional stores due to the processes needed to get them there.
You may lose weight on the Paleo Diet. If you build a “calorie deficit” into your Paleo plan – eating fewer calories than your daily recommended max or burning off extra by exercising – you should shed some pounds. How quickly and whether you keep them off is up to you. A 2015 review in the Journal of Gastrointestinal Liver Diseases concluded that a Paleo-esque diet “might be an acceptable antidote to the unhealthy Western diet, but only unequivocal results from randomized controlled trials or meta-analyses will support this hypothesis.” On that, we’re still waiting. In the meantime, here’s what has been found about the diet and others like it:
Why so strict? According to the diet's founders, Melissa and Dallas Hartwig, these are the foods that are most likely to cause inflammation and gut damage. They're also the foods that the founders say destabilize blood sugar levels and lead to cravings. But it's hard to say whether that's true for everyone. In general, limiting sugar and alcohol is always a good idea. But dairy, grains, and legumes? They don't trigger an inflammatory response in everyone, Haas says.
I experienced some funky physical symptoms during the first 10 days or so, but this is pretty typical of a Whole30. I would feel great, and then the next day I would feel tired, achy, and bloated. Depending on what your diet was like before you started the Whole30, you’re bound to get hit by some sort of detoxing symptoms. If you’re doing this after eating a lot of sugar and processed food, your symptoms might be a bit more severe. However, the book assures you it’s normal, and it will even out. According to the authors, the bacteria in your gut are shifting and creating a new landscape. Your body is getting used to this new diet of protein and a ton of veggies with the absence of sugar. Things adjust and shift. For me, this meant a couple days of feeling off.
Since 2009, Melissa Hartwig’s critically-acclaimed Whole30 program has quietly led hundreds of thousands of people to effortless weight loss and better health—along with stunning improvements in sleep quality, energy levels, mood, and self-esteem. The program accomplishes all of this by specifically targeting people’s habits and emotional relationships with food. The Whole30 is designed to help break unhealthy patterns of behavior, stop stress-related comfort eating, and reduce cravings, particularly for sugar and carbohydrates. Many Whole30 participants have described achieving “food freedom”—in just thirty days.
LOREN CORDAIN, Ph.D., is one of the top global researchers in the area of evolutionary medicine. Generally acknowledged as the world's leading expert on the Paleolithic diet, he is a professor in the Health and Exercise Science Department at Colorado State University. Dr. Cordain and his research have been featured on Dateline NBC and in the New York Times, the Wall Street Journal, and other media. He is the author of The Paleo Diet and The Paleo Diet Cookbook, among other books, and makes regular media and speaking appearances worldwide.

For many years Arthur De Vany Ph.D. has been writing a book called Evolutionary Fitness on "What Evolution Teaches Us About How to Live and Stay Healthy." The diet he follows fits into my core diet definition. He may have been the first one to use the paleo diet to maximize fitness. His current site is Art's Blog on Fitness, Health, Aging, Nutrition and Exercise [archive.org].
I thought Week 1 was hell on earth, but boy was I wrong. Week 4 tested my patience and willpower like never before. Eating Whole30 staples like avocado and eggs became a chore. I choked down so many hard-boiled eggs during my last week, but all I could think about was how I wished they were freshly baked bagels—or even just a bowl of plain white rice. Anything but eggs.

In making the case for meat, Cordain presents anecdotal evidence of Eskimos who lived their full life without a heart attack. The Eskimo diet consists of 97% meat, which he concedes causes all Eskimos to develop atherosclerosis—a common precursor to heart disease. But Cordain says Eskimos never die of heart disease. He discusses one Eskimo who lived 45 years and another who lived 53 years, both without heart disease! He then jumps to the conclusion that because these Eskimos didn’t get heart attacks, even with severe atherosclerosis, meat must have protected them from heart disease. So Cordain’s best case for lots of meat is that you can live to the ripe age of 45 or even 53 without a heart attack. But do people—even unhealthy smokers or the obese—generally get heart attacks before age 53?
Cordain argues that chimpanzees and horses avoid meat, and they have big bellies that we would have if we didn’t ditch plants for meat. He also says meat increased human brain size, and decreased stomach size so we can have the six-pack abs that chimps can’t. But I looked at his endnotes with citations to research and couldn’t find the source for these theories. I also couldn’t find research showing that legumes and grains were invented by humans.
The theory is our bodies were designed, and still optimized, to eat what our Paleolithic ancestors ate. Like your hunger-gatherer forefathers, on Paleo you get all the meat from wild animals and unlimited fruits and vegetables you can eat. But no starchy vegetables (like potatoes), no legumes (like lentils or beans), no wheat, and no grains (like quinoa or corn) because those plants were invented by human beings during the agricultural revolution after our Paleolithic ancestors left the planet. You get one cheat day where you can eat whatever you want (“Occasional cheating and digressions may be just what you need to help you stick to the diet.”) No oil because it puts omega 6 and omega 3 ratios out of whack which should never exceed 2:1, except olive oil if you must. Dairy is also prohibited. And meat must come from animals that weren’t fed grains (like corn) because grains lead to inflammation and increased fat.
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.
Richard Nikoley has the blog Free The Animal. He loves meat eating. His diet is near paleo, with the addition of some gray-area foods that he likes. These days most of his posts are on food. One recent trend in the paleo community is trying to optimize the proportions of the foods eaten. If you've read my definition you'll know that I simply define the diet as foods in and out. One of Richard's posts: Optimality: A Fool's Errand? has produced a long discussion of this trend.
It takes 30 days to push the reset button on your health and change your relationship with food. This is the concept behind Melissa and Dallas Hartwig’s Whole30 program. By eating non-processed whole foods and ditching grains, dairy, and sugar, you will reduce inflammation in your system, clear up your skin, and revitalize your energy stores. These are just a few of the benefits this program boasts.
Optimal Diet is a dietary model of human nutrition devised and implemented by Dr. Jan Kwasniewski. Lots of fat and low in carbs. Lots and lots of articles collected from various places. He has an out-of-print book: Optimal Nutrition. The book is explained at the Australian Homo Optimus Association website. A thorough analysis is the first post here: Dr. Kwasniewski's Optimal Diet: Sanity, Clarity, Facts.
Legumes are members of a large family of plants that have a seed or pod. This category includes all beans, peas, lentils, tofu and other soyfoods, and peanuts. Legumes are not allowed on paleo because of their high content of lectins and phytic acid. Similar to grains, this is a point of controversy in the scientific community. In fact, lots of research supports eating legumes as part of a healthy diet because they are low in fat and high in fiber, protein and iron.

CrossFit is a strength and conditioning program consisting mainly of a mix of aerobic exercise, calisthenics (body weight exercises), and Olympic weightlifting.[16] CrossFit, Inc. describes its strength and conditioning program as "constantly varied functional movements executed at high intensity across broad time and modal domains,"[17] with the stated goal of improving fitness, which it defines as "work capacity across broad time and modal domains."[18] 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.[19]
