How many times have we all heard this bunk myth repeated?
“Humans can’t actually digest meat: it rots in the colon.”
And its variant: “Meat takes 4-7 days to digest, because it has to rot in your stomach first.”
(Some variations on this myth claim it takes up to two months!)
Like most vegetarian propaganda, it’s not just false, it’s an inversion of truth. As the proverb says, “When you point your finger, your other three fingers point back at you.” Let’s take a short trip through the digestive system to see why!
A Trip Through The Human Digestive System (abridged)
Briefly, the function of digestion is to break food down as far as possible—hopefully into individual fats, amino acids (the building blocks of protein), and sugars (the building blocks of carbohydrates) which can be absorbed through the intestinal wall and used by our bodies.
Click to zoom in.
Here we go!
We crush food in the mouth, where amylase (an enzyme) breaks down some of the starches. In the stomach, pepsin (another enzyme) breaks down proteins, and strong hydrochloric acid (pH 1.5-3, average of 2…this is why it stings when you vomit) further dissolves everything. The resulting acidic slurry is called ‘chyme’—and right away we can see that the “meat rots in your stomach” theory is baloney. Nothing ‘rots’ in a vat of pH 2 hydrochloric acid and pepsin.
On average, a ‘mixed meal’ (including meat) takes 4-5 hours to completely leave the stomach—so we’ve busted yet another part of the myth. (Keep in mind that we have not absorbed any nutrients yet: we’re still breaking everything down.)
Click the picture for more fascinating information on gastrointestinal transit times!
Eventually our pyloric valve opens, and our stomach releases the chyme, bit by bit, into our small intestine—where a collection of salts and enzymes goes to work. Bile emulsifies fats and helps neutralize stomach acid; lipase breaks down fats; trypsin and chymotrypsin break down proteins; and enzymes like amylase, maltase, sucrase, and (in the lactose-tolerant) lactase break down starches and some sugars. Meanwhile, the surface of the small intestine absorbs anything that our enzymes have broken down into sufficiently small components—usually individual amino acids, simple sugars, and free fatty acids.
Finally our ileocecal valve opens, and our small intestine releases what’s left into our large intestine—which is a giant bacterial colony, containing literally trillions of bacteria! And the reason we have a bacterial colony in our colon is because our own enzymes can’t break down everything we eat. So our gut bacteria go to work and digest some of the remainder, sometimes producing waste products that we can absorb. (And, often, a substantial quantity of farts.) The remaining indigestible plant matter (“fiber”), dead gut bacteria, and other waste emerge as feces.
It turns out that pepsin, trypsin, chymotrypsin, and our other proteases do a fine job of breaking down meat protein, and bile salts and lipase do a fine job of breaking down animal fat. In other words, meat is digested by enzymes produced by our own bodies. The primary reason we need our gut bacteria is to digest the sugars, starches, and fiber—found in grains, beans, and vegetables—that our digestive enzymes can’t break down.
Now what is that called, again, when food is being ‘digested’ by bacteria…?
rot \ˈrät\ (verb) — to undergo decomposition from the action of bacteria or fungi
In other words, meat doesn’t rot in your colon. GRAINS, BEANS, and VEGETABLES rot in your colon. And that is a fact.
…And That’s Why Beans Make You Fart
It’s easy to tell when your gut bacteria are doing the work, instead of your digestive enzymes: you fart. That is why beans and starches make you fart, but meat doesn’t: they’re rotting in your colon, and the products of bacterial decomposition include methane and carbon dioxide gases. Here’s a list of flatulence-causing foods, and here’s another:
A partial inventory: “Beans, lentils, dairy products, onions, garlic, scallions, leeks, turnips, rutabagas, radishes, sweet potatoes, potatoes, cashews, Jerusalem artichokes, oats, wheat, and yeast in breads. Cauliflower, broccoli, cabbage, Brussels sprouts and other cruciferous vegetables…”
One side benefit of a paleo diet is the elimination of the biggest, stinkiest fart producer—beans (due to the indigestible sugar raffinose)—and several smaller ones (wheat, oats, all grain products). And it sure seems like my gut bacteria have less to do now that my amylase and sucrase supplies aren’t being overwhelmed by an avalanche of starch and sugar.
But wait! There’s another punchline! Whenever we eat grains, beans, and vegetables, we’re not digesting and absorbing much of the plant matter…we’re actually absorbing bacterial waste products. Rephrased less diplomatically:
You’re not eating plants: you’re eating BACTERIA POOP.
Supporting Evidence: Where Things Rot
I know I really should have ended this article at the punchlines, but I’ve got more to say. Digestion is fascinating! (And before we go any farther, I am not arguing that we should never eat vegetables: I’m just busting a silly myth.)
First, I’ll footnote the essay above with these references.
J Appl Bacteriol. 1988 Jan;64(1):37-46. Contribution of the microflora to proteolysis in the human large intestine. Macfarlane GT, Allison C, Gibson SA, Cummings JH.
“In the stomach and the proximal small bowel, the microorganisms found as normal flora are a reflection of the oral flora. Bacterial concentrations in this region are 10(2)-10(5) cfu/ml intestinal content. In the colon, bacterial concentrations of 10(11)-10(12) cfu/g faeces are found.”
In other words, there are roughly 10 million times as many bacteria in the colon as in the small intestine. So bacterial digestion (‘rotting’) is not significant anywhere in our digestive tract but the colon.
Appl Environ Microbiol. 1989 Mar;55(3):679-83. Significance of microflora in proteolysis in the colon.Gibson SA, McFarlan C, Hay S, MacFarlane GT.
“Proteolytic activity was significantly greater than (P less than 0.001) in small intestinal effluent than in feces (319 +/- 45 and 11 +/- 6 mg of azocasein hydrolyzed per h per g, respectively).”
That’s a mere 3.4% of proteolytic activity occurring in the feces vs. the small intestine…and that doesn’t count what already occurred in the stomach. If meat were being digested in the colon, we would expect a far greater amount of proteolysis to occur there. And that 3.4% is likely due to dead intestinal bacteria (which make up a significant fraction of feces), not undigested meat.
Then, I’ll add this firsthand experience from an intestinal transplant survivor who spent months with a jejunostomy, watching the contents of his stomach drain directly into a bag.
“Can Humans Digest Meat?”
“Because I had such an extremely short bowel, my output was very high because no absorption had taken place. I was fed and hydrated by infusion and could literally live without eating or drinking at all. Because of my excessive output, we had to make a rig that had a hose extending from the ostomy bag that drained into a one gallon jug. Often the hose would get clogged and my wife or sister would have to use a coat hanger wire to unplug it. Now if vegan pseudoscience is right, we would suspect that the hose was being plugged by pieces of meat.
“Never once did we see any solid chunks of meat. I became so curious about this that I once swallowed the largest chunk of meat I could possibly get down without choking. Because of the shortness of my bowel, it only took about twenty minutes for my stomach to empty into the ostomy. Better than two hours later, there were no signs of any meat chunks. What was always clogging the ostomy tube were pieces of vegetables that were not fully chewed.
“Entire pieces of olive, lettuce, broccoli florets, grains and seeds were found. Yet, large pieces of fat were never witnessed. As a matter of fact, all the fat from the meat was already emulsified by the bile into solution. Over time, fat would coagulate on the side walls of the ostomy bag, but never were there any solid pieces observed.”

Most Vegetation Doesn’t Even Rot In The Colon, Because Humans Aren’t Herbivores
Most of the edible part of a plant is cellulose, a polysaccharide (i.e. a very long chain of sugars) that is very difficult to break down. In fact, no digestive enzyme, in any animal, is capable of breaking down cellulose! So the only way that any animal can fully digest plants is for its gut bacteria to break down cellulose, and its intestines absorb the waste products.
Ruminant digestive system, courtesy of the University of Minnesota. Click for article.
Ruminants, including cattle, bison, deer, antelope, goats, and other red meat, have a special “extra stomach” called the rumen. They chew and swallow grass and leaves into the rumen, ferment it some, barf it back up again, chew it some more (called “chewing the cud”), and swallow it again, where it is digested a second time. Hindgut fermenters, like horses, have an extra-long gut. And rabbits run their food through twice: they eat their own poop in order to get more food value out of the plant matter they eat.
(For a more in-depth explanation of herbivore digestion, with lots of pictures, click here for an informative presentation (pdf) from the University of Alberta’s Department of Agriculture.)
Humans, in contrast, don’t have gut bacteria that can digest cellulose. That is why we can’t eat grass at all, why there is so little caloric value for us in vegetables, and why we call cellulose “insoluble fiber”: it comes straight out the back end.
This fact alone proves that humans, while omnivores, are primarily carnivorous: we have a limited ability to digest some plant matter (starches and disaccharides) in order to get through bad times, but we cannot extract meaningful amounts of energy from the cellulose that forms the majority of edible plant matter, as true herbivores can. We can only eat fruits, nuts, tubers, and seeds (which we call ‘grains’ and ‘beans’)—and seeds are only edible to us after laborious grinding, soaking, and cooking, because unlike the birds and rodents adapted to eat them, they’re poisonous to humans in their natural state.
You can demonstrate the purpose and limits of human digestion with a simple experiment: eat a steak with some whole corn kernels, and see what comes out the other end.
It won’t be the steak.
Live in freedom, live in beauty.

Imagining Head-Smashed-In, by Jack W. Brink
One of the primary conceits of history is that nothing happened before agriculture. The Great Leap Forward! Between the Tigris and the Euphrates, the cradle of civilization! Page 1 of any sixth-grade world history textbook.
And before that?
Nothing, as far as we’re told. Unremitting savagery, a life nasty, brutish, and short, cavemen killing each other with clubs and dragging women by the hair. A life not worth a chapter, or even a page, to describe it.
Yet an awkward fact remains: these ‘savages’ were modern humans. In fact, they were taller, stronger, healthier, had larger brains and better teeth, and were longer-lived than the farmers that replaced them (see: Jared Diamond, Claire Cassidy).
And somehow these ‘savages’ managed to invent agriculture—a task much more difficult than practicing it. They discovered how and when to sow. They discovered how to plow, how to weed, how to protect crops against birds and rodents, how to harvest and thresh and grind and cook and bake…a suite of tasks that remained essentially unchanged for 10,000 years after their original discovery.
In other words, those ‘savages’ must have been pretty damned smart.
But how did they become so smart? It can’t have had anything to do with agriculture or anything we consider ‘civilized’, because they invented all that. What caused little 65-pound savanna apes with 350cc brains to evolve into Late Paleolithic modern humans with 1500cc brains?
Clearly there was much more to Paleolithic life than dumb savagery.
I will now turn this essay over to Jack W. Brink, archaeologist and author of “Imagining Head-Smashed-In: Aboriginal Buffalo Hunting on the Northern Plains.” From the Preface:
The book isn’t about what are traditionally considered the great historic achievements of our species. There are no magnificent cities built, no colossal monuments erected, no gigantic statues carved, no kingdoms conquered. It was very much this deviation from classical concepts of “civilization” that motivated me to write this book. Modern society seems to equate human achievement with monumental substance and architectural grandeur. Asked to name the greatest accomplishments of ancient cultures you would certainly hear of the Great Wall of China, Stonehenge, the Great Pyramids, and the civilizations that ruled Greece and Rome. Shunted off to the side are many ancient cultures that achieved greatness through their skill, knowledge, and ingenuity – cultures that managed to survive in demanding environments for extraordinary lengths of time without leaving towering monuments to themselves. In the coming pages I hope to show how simple lines of rocks stretching across the prairies are every bit as inspirational as rocks piled up in the shape of a pyramid.
This is a book about one of the truly remarkable accomplishments in human history. It is the story of an unheralded, unassuming, almost anonymous group of people who hunted for a living. They occupied an open, windswept, often featureless tract of land. They lived in conical skin tents that they lugged around with them in their search for food. A life of nearly constant motion negated permanent villages and cumbersome material possessions. They shared this immense landscape with herds of a wild and powerful beast – the largest animal on the continent. In a land virtually without limits, people of seemingly unsophisticated hunting societies managed to direct huge herds of buffalo to pinpoint destinations where ancient knowledge and spiritual guidance taught them massive kills could be achieved. It was an that guaranteed survival of the people for months to come, a that ensured their existence for millennia. Using their skill and their astonishing knowledge of bison biology and behaviour, bands of hunters drove great herds of buffalo over steep cliffs and into wooden corrals. In the blink of an eye they obtained more food in a single moment than any other people in human history. How they accomplished this is a story as breathtaking in scope and complexity as the country in which the events unfolded.
What follows is a fusion of archaeology and narrative, as Brink attempts to reconstruct the details of a buffalo jump—an event that last occurred in the 1800s, far outside anyone’s living memory. As he puts it:
Head-Smashed-In Buffalo Jump in southern Alberta, Canada, is but one of many places where herds of bison were brought to their deaths by the Native inhabitants of the Plains. It forms the nucleus around which my story unfolds. But this is not so much the story of one place, one people, or one time. It is the story of countless people who thrived over an enormous expanse of time and territory by orchestrating mass kills of bison. There were two reasons I wanted to write this book. First, to bring to a wider audience a story that I felt was so compelling and inspirational that it should not be allowed to fade from contemporary memory. And second, to do justice to the people who orchestrated these remarkable events.
The text of “Imagining Head-Smashed-In” runs to over 300 pages, which should be our first clue that this was not a trivial task. Indeed, reading it gives a nearly vertiginous sense of the skill, ingenuity, and sheer tenacity required to survive in the extreme environment of the Northern Great Plains. What we modern humans think of as “wilderness survival” basically consists of avoiding immediate death until someone in a helicopter rescues us—or, worst case, walking in one direction until we reach the safety and familiar problems of ‘civilization’, which is to say: other people. Obtaining food is not a concern, because humans can survive several weeks without food: ‘wilderness survival’ is a temporary state of privation, to be escaped as quickly as possible.
Yet for millions of years—the entire span of time and circumstances that shaped us from small, dumb apes into modern humans—daily life was far more challenging that what we think of today as ‘wilderness survival’. The problems of everyday life could not be postponed until we reached a hospital, a supermarket, or even a paved road—and they had to be addressed without maps, compasses, Gore-Tex, matches, or even a metal knife. Sickness, injury, and childbirth. Freezing cold, searing heat, pouring rain. And the continual, omnipresent drive of all life: hunger. The need to eat something nutritious so that you have the energy to live one more week, one more day, one more hour.
Yet Paleolithic humans met that challenge and mastered it—for we spread out of Africa and around the entire world, even to the smallest, most isolated Pacific islands. We survived in humid jungles and parched deserts, in howling blizzards and torrential downpours, on prairies and forests and valleys and mountains and beaches and anywhere there was living flesh for us to kill and eat. And we were such accomplished hunters and killers and eaters that we drove most of the big, slow animals to extinction.
Pyramids, in contrast, are uninteresting. All you need is tens of thousands of slaves to stack rocks until they die. Hunting is the real human history. Yet since it left behind nothing but stone points and bones smashed open for marrow, its stories are lost to us forever. All we can do is imagine.
And that is what Jack Brink does for us: he imagines one of the uncountable stories of the real human history.
Who could imagine that a book of North American archaeology could leave me near tears?

Survival by Hunting, by George Frison
While “Imagining Head-Smashed-In” creates a strangely poignant narrative out of archeology, George Frison’s “ Survival By Hunting” is a far more utilitarian book. If IHSA is a beautifully-constructed diorama in the museum located at the jump site, “Survival By Hunting” is one of the shovels used at the dig.
Just as IHSA is a combination of archaeology and narrative reconstruction, “Survival by Hunting” is a combination of archaeology and biography. Frison briefly tells his story as a child growing up in rural Wyoming on his grandfather’s ranch, and of both the culture and essential privation (he grew up during the Depression) that led to becoming a subsistence hunter at a young age. As a hunter he found many tools and traces of the Native American hunters who had previously inhabited the area, hunting the same game he had. An abiding interest in these remains led to a career in archaeology, which combines with his decades of experience hunting large animals to make him the leading authority on Prehistoric hunting techniques.
Though written very dryly, the book is an entertaining combination of factual academic recountings of artifact sites and his own personal experience. Instead of simply speculating how prehistoric hunters might have butchered mammoths with stone tools, Frison flies to Africa and tries it himself on an elephant carcass culled from a nature reserve—proving that stone tools are indeed sufficient to the task of cutting through elephant hide. And not content to guess at the force of a dart or spear thrown by an atlatl (spear-thrower) and whether it might be sufficient to kill a mammoth, he learns to make them himself—and tests them, again on an elephant carcass. Only someone with Frison’s experience at real-life game hunting, and Frison’s willingness to test his theories by experiment, could accumulate the knowledge he does—let alone assemble it into charmingly tentative hypotheses about the nature and significance of an archaeological site.
Reading “Survival by Hunting” is a bit like being on an dig oneself: startling artifacts of knowledge are strewn randomly about the narrative, often covered with dirt and mentioned only in passing. For instance:
Woodruff said that during the last half of the nineteenth century, [mountain] sheep were so plentiful that any time they were short of meat they hitched up a wagon, drove along the base of the steep east slope of the Absaroka Mountains, and loaded the wagon with sheep as they were shot and rolled to the bottom.
This offhand anecdote provides a glimpse of the cornucopia that must have been pre-contact North America, even after thousands of years of Native American hunting and subsequent extinctions. In contrast, our few remaining scraps of modern ‘wilderness’ are, for the most part, beautiful but lifeless high-altitude tundra. And hunting today is either completely prohibited or carefully managed, with thousands of would-be hunters vying for a tiny number of tags handed out by lottery—those tags costing many times in excess of the value of the meat.
As the book progresses, we learn that an elk antler tip can serve as an atlatl hook; that bison can squeeze through openings which cattle cannot; that pronghorn can run at over 45 MPH but refuse to jump or crash through a flimsy ‘fence’ made of brush; and hundreds of other small knowledge artifacts that only assemble themselves into a coherent whole in retrospect and upon reflection.
To summarize “Survival by Hunting”, I’ll quote the Preface:
Equally disturbing to me is the attitude students are acquiring towards hunting…students questioned about animal procurement strategies commonly respond, “When they got hungry, someone would kill a bison or whatever other animal was selected as the target for the day and bring it back to camp.” I believe such interpretations to be totally inadequate, and I hope that the contents of this book convince others of the vast reservoir of learned behavior involved in hunting.
All I have to say is: what George said.
(His criticism can be applied equally to many archaeologists, whose ignorance of basic physics, let alone hunting strategies, is blatantly obvious—but that’s another article for another time.)
“Survival by Hunting” may not have the grand narrative scope of “Imagining Head-Smashed-In”. But if you want to understand another tiny fragment of the real human history—which is how Plains hunters managed to kill mammoths, bison, and antelope on foot, using only sharp rocks and their wits—this book will get you there.

This article exists for one simple reason: I get asked, over and over, “So how does this ‘paleo diet’ work?” And I want to give people an answer that is simple, solid, and above all, motivational. I want you to finish this article and think “Yes! I understand, and I can do this.”
Here it is: a step-by-step guide, roughly in order of importance. Make progress at whatever pace you can. Don’t stress about perfect adherence, or obsess about making it all the way down the list: any progress you make will most likely improve your health, mood, and physical fitness.
“Do not eat” items are grouped with “Eat more” items at each step, so you’ll always have something to eat. Let’s go!
First, our guiding philosophy:
Eat like a predator, not like prey.
Predators gorge and fast; prey grazes.
Rephrased for modern humans: predators eat meals, prey grazes on snacks. This means you need to eat meals which will carry you through to your next meal, but that won’t make you tired or sleepy.
Here’s how!
Step 1: Eat Meat, Not Birdseed
- Eat more meat. If it’s not meat, it’s not a meal.
- Favor ruminants—animals that eat grass and leaves. (That means red meat: beef, lamb, bison, elk, venison, goat.) Ruminants are far better at converting plants into essential fats, complete protein, and bioavailable nutrients than humans are.
- Buy grass-fed beef whenever possible: it’s better for you, and better for the Earth. Cows didn’t evolve to eat corn and soybeans any more than humans did.
- Buy fatty cuts, buy occasional organ meats. Do not avoid animal fat! If you try, you will become ravenous for fatty junk food.
- Pork and chicken are permissible in moderation, but are far less healthy due to excessive omega-6 fat content.
- Frankly, you could stop here, as many native cultures did: as long as you eat organ meats and marrow, fatty, grass-fed ruminant meat provides 100% of your nutritional needs. But most of us enjoy more variety in our diets—and some vegetables and fruits offer tangible health benefits, even if they don’t provide meaningful calories.
- Eat more fish and shellfish.
Favor oily fish like mackerel, sardines, and wild salmon, but be careful of methylmercury content: keep your intake of tuna, shark, and other high-level carnivores low. (The FDA’s table of mercury content can be found here.) In a Paleolithic world we could eat all the fish we wanted…but we humans have polluted the entire Earth so badly (mostly by burning coal for power) that one of our healthiest food sources is now universally poisonous. Good job, ‘civilization’.
- Do not eat anything made with ‘flour’.
No bread, no pasta, no cereal, no crackers, no cookies, no donuts or danishes. Period. This is your most important step. Flour is ground-up seeds. What eats seeds? Birds and rodents. If it’s poisonous to humans until we grind it into powder and cook it, and it causes mineral deficiencies and birth defects unless we add vitamins, it’s not food. (Read more about lectins, phytic acid, and the role of grains in autoimmunity and heart disease.)
- Do not drink your food.
No soda (even diet soda), no sports drinks, no milk, no soy ‘milk’, no smoothies, no fruit juice, no yogurt or vegetable drinks. Tea, coffee, and mate are fine in moderation. Learn to drink water: once you get used to it, you’ll find that soda and juices no longer quench your thirst. (You can potentially add small quantities of dairy and fresh fruit/vegetable juices back in later, if you’ve met your other goals.)
- Do not eat table sugar, or its equivalents.
This includes circumlocutions like “brown rice syrup”, “agave nectar”, and my favorite, “evaporated cane juice solids.” That’s what sugar is! Sheesh. Even honey is basically just sugar, though it has useful medicinal properties. Diet sweeteners are out, too, as are those goofy Atkins sugar alcohols.
- Get your ‘carbohydrates’ (sugars) from plants—not their seeds.
Prefer foods that are high in glucose and low in fructose, particularly root starches like potatoes, and only eat what your body needs: 15-20% of calories is plenty. (Do you want to lose fat? Then you’d better accustom your body to burning it for energy.)
Important! If you are active and not concerned with losing weight (or trying to gain it), you’ll want to eat more carbs than the average person trying to lose a few pounds. Sports nutrition is beyond the scope of this article…but in general, I find occasional starch refeeds, when necessary to refill muscle glycogen, much better than a constant diet of pasta, “energy bars”, and other sugary junk food. Basically, if you find yourself bonking during long, intense efforts, try upping your starch intake.
Don’t forget about sweet potatoes, sago, taro, sweet cassava, and tapioca…and always peel your potatoes, as that’s where the solanine is. If you must eat birdseed, white rice is the least bad of the grains…but give yourself a couple weeks to see if it’s just withdrawal symptoms, or whether you really need it on a regular basis.
Remember, fatty meat is your primary source of calories and nutrients. Quite a few ‘mainstream’ paleo books and sources sugarcoat or dance around this. You’re a predator: eat like one.
Congratulations! You’ve just made some massive, positive changes in your life.
You may be going through bread and cereal withdrawal, with periods in which you absolutely crave them. This is absolutely normal: you’re forcing your body to learn how to burn fat again, because it’s used to burning all the sugar (‘carbohydrates’) you’ve been eating.
However, you’re probably already noticing an increase in energy, a decrease in post-meal fatigue, and a lessened desire to snack. Stay on target! The cravings will dissipate, but the benefits won’t.
The best part about a primal/’paleo’ diet is that you don’t have to measure or keep track of anything: no counting calories, no ‘points’, no worries about macronutrient ratios. Eat real food, and you won’t have to worry about parceling out your addiction to junk.
Step 2: Eat Food, Not Diesel Fuel
- Buy fatty cuts of meat, cook with their included fat.
If you need to douse it in butter to make it taste good, it’s too lean. I always laugh when I see people making sandwiches with low-fat hamburger or skinless chicken breast—then covering them with cheese and mayonnaise because they’re too dry! Hint: ask your butcher for untrimmed cuts of meat. Often they’re cheaper.
- Cook with butter, coconut oil, and grass-fed beef tallow.
These are healthy fats: they don’t oxidize or polymerize during cooking the way that seed oils do, they don’t contain hidden trans fats, and they have low to zero omega-6 fat content.
I discourage lard unless it’s from pastured pigs: store-bought lard is usually hydrogenated (= trans fats), and grain-fed lard is high in omega-6 fat.
- Cook with eggs, and always eat the yolks.
Egg whites are just protein…the nutrition is all in the yolk. And few foods remain unimproved by the addition of a fried egg.
- Do not eat “vegetable oils”. The term itself is a lie.
There’s no such thing as “lettuce oil” or “broccoli oil”. They’re made from seeds, and they’re extracted using poisonous organic solvents (hexane). Remember: if you can put it in a truck and the truck starts, it’s not food.
- This means no french fries or other deep-fried food; no potato chips or corn chips (or any ‘chips’); no margarine, ‘spread’, or bogus butter substitutes; no mayonnaise (or, worse, Miracle Whip); and you can basically ignore the entire snack aisle.
- This prohibition includes granola, which is just birdseed stuck together with oil and sugar. Corn ‘nuts’ and wasabi peas are soaked in oil, too: frankly, nothing in those bulk bins is food. One of the best things you can do for your health is to avoid everything you see in the ‘health food’ aisles.
- Extra-virgin olive oil, cheese, avocados, and nuts are OK in moderation…think of them as condiments, not ingredients. If you need to eat a can of nuts or a brick of cheese, you didn’t eat enough meat.
- Heavy cream, sour cream, full-fat yogurt (not that worthless ‘low-fat’ candy), and whipped cream make delicious sauces, condiments, and desserts, used in moderation. But remember that fatty meat is always your primary source of calories.
Well done! You’ve made another big step towards better health and greater vitality. You’re no longer shuffling through life like a wounded gazelle, expecting the jaws of death on its neck at any moment. You are becoming less tasty and more dangerous each day.
Yes, we all need some moral support when we give up potato chips and corn chips. But wouldn’t you rather have an omelet for breakfast, and then not have to snack at all? Butter, eggs, and coconut oil taste much better than seed oils and ‘spreads’…and after you’ve used them for a while, you’ll start noticing that canola oil smells terrible, and that your food is much less greasy despite a much higher fat content.
Most importantly, now that you’re no longer eating huge plates of sugar (‘carbohydrates’) and greasy seed oils, you’ll find that big, hearty meals don’t make you fall asleep. You’ll also find that it’s much easier to go without food now that your body is reaccustomed to burning fat. In short, you’ll have more useful hours in your day now that you’re not spending them stuck in food coma, or constantly grazing to keep from going hypoglycemic—which more than makes up for the extra time you’re spending on cooking and buying food.
Besides, shopping for food is quick and easy when the only places you have to go are the meat counter, the produce bins, the dairy refrigerator, and the spice rack.
Step 3: Supplements For An Imperfect World
- Consider vitamin D3 supplements.
Our bodies naturally produce vitamin D3 from sun exposure…but Paleolithic humans didn’t live and work indoors. 2000-4000 IU per day is, from what I understand, a good start for most adults on days they’re not getting meaningful sun exposure. Testing for 25(OH)D levels will tell you if your dosage is correct: 45-60 ng/mL is apparently a good place to be.
- Consider EPA and DHA (“omega-3”) supplements.
The seed oils and grain-fed meat we’re often forced to eat are higher in pro-inflammatory omega-6 fats, and lower in anti-inflammatory omega-3 fats, than natural grass-fed meat. 1g/day of EPA and 0.5g DHA can be helpful if you haven’t eaten any fatty fish that day; more if you’re pregnant or nursing.
Note that it’s much better to minimize omega-6 intake by eliminating seed oils and reducing nut intake, than it is to “balance your ratio” with pathological quantities of fish oil.
- Flaxseed oil (ALA) is not an acceptable substitute.
Our bodies are woefully inefficient (less than 1%) at converting it to the DHA we require. Besides, its real name is linseed oil. That’s furniture polish, and furniture polish is not food.
- Consider chelated magnesium supplements.
Until the last few decades, humans drank untreated ground water or well water, usually with high mineral content—but modern treatment plants strip them from our tap water.
The bioavailable forms of magnesium, and the ones you should buy, are chelates: any form ending in -ate. Magnesium citrate has a laxative effect that some people don’t tolerate well—in which case magnesium malate, glycinate, or orotate will be superior. The RDA of 400 mg/day is a good start. (Avoid magnesium oxide, found in most supplements and all multivitamins, as it’s not bioavailable.)
- I am not a doctor, and you are responsible for your own health. Do your own research, and if you notice adverse effects, use common sense. What your body tells you is more important than what a website tells you.
If you get to here, you’re doing great—and you’re already far healthier than you were on the SAD (Standard American Diet) even if you haven’t lost any weight. (But odds are good that you have.) You’re also probably noticing, over time, that you’re happier and less depressed, that your skin problems and allergies are less severe (or gone entirely), and that you sunburn less easily.
Step 4: Play Like A Predator
- Play hard, work hard, challenge yourself, then rest.
Lift heavy objects, sprint until you’re out of breath, climb trees and jump down, kick balls, shoot baskets. Shovel snow, dig dirt, split firewood. Practice agility as well as strength and endurance. People will stare at you if you’re doing it right, because you’re enjoying yourself—not shuffling down the road in ‘running shoes’, with that vacant look of resigned suffering usually seen on wildebeest being eaten alive by hyenas. The world is your playground! (And if others won’t take advantage of it, too bad for them.)
- Don’t ‘exercise’, don’t ‘do cardio’. The only way to improve is to push your limits.
You’ll lose more weight and gain more strength from periodic bursts of short, intense exercise than from hours of ‘cardio’. You’re a human, not a hamster; get off the treadmill! Seriously: drive to work, then drive to the health club so you can pedal a bicycle that goes nowhere? Imagine this: every time you get hungry, you and your six closest friends have to chase down an antelope or spear a mammoth—and if you can’t, none of you get to eat. That is the required intensity.
- If you must ‘work out’, do bodyweight exercises, and get some dumbbells or kettlebells.
That way you can finish a workout before you’ve even arrived at the gym. Our objective is health and fitness: a gym body is a lot more work. (Do it if you want, and I admire those with the dedication to sculpt themselves—but it’s not necessary.) Remember, you should be doing short, intense bursts of activity throughout the day: you’re not going to drive to the gym three times.
Note: If you have the time and genuinely enjoy it, absolutely lift heavy weights and get strong. Especially women: you’re not going to suddenly become 1970’s Arnold just because you do squats, and any man who thinks you’re “too muscular” because you don’t look like a heroin addict is weak, insecure, and not worth your time.
- Stop trying to ‘save energy’. Make physical effort part of your life. Don’t waste time looking for the closest parking space: just park and walk. Take the stairs. Shovel your own snow, split your own firewood. Unless you’re a cabinetmaker or construction worker, do you really need that cordless screwdriver?
Congratulations! You’ve put all the pieces together. Most likely you are sleeping better now that you’re regularly putting forth physical effort. You’re thinking of the world as your playground, and you’re seeing familiar surroundings with new eyes. And now that your symptoms of withdrawal from the SAD (Standard American Diet) are over, you’re feeling more energetic—and thinking more clearly due to the action of ghrelin, now that being hungry doesn’t just make you cranky and hypoglycemic.
In other words, your body is finally—perhaps for the first time—beginning to function as it should.
Now that you are physically stronger, you will find that you are emotionally and mentally stronger. You are less willing to be walked on and taken for granted, and more likely to take credit for what you deserve. You are beginning to understand what it feels like to be a predator, instead of the prey you’ve been for so long.
You’ve tasted power, and it’s delicious. You want more.
Step 5: Optimization
By now we’re just cleaning up loose ends. Some of you may never get here, some may find it doesn’t make much difference to you and drop back, some may find here the key to optimal health.
- Remove any remaining grains from your diet.
They should be mostly gone already, but if you’re still eating corn, oats, or any bogus ‘health grains’ like kamut or amaranth, ditch them. Absolutely eliminate all gluten grains from your diet: wheat, barley, rye, spelt. (You should have done this already by eliminating flour in Step 1, but people always find a way to sneak in ‘wheat berries’ or some other bogus name for seeds. And gluten hides in all sorts of things you don’t realize.)
- Remove any remaining legumes (beans) from your diet.
This is usually easy once you’re getting plenty of fat and protein from meat. Like grains, beans are seeds—and they’re for birds and rodents, not humans.
- Remove all remaining junk from your diet.
There are a lot of non-foods that technically sneak through the above rules, but which we all know perfectly well are junk. I’m not going to enumerate them, because there are thousands…but if it has more than one layer of packaging, contains any ingredient you don’t understand, claims any health benefits on the label, or is a fake version of something else, it’s not food.
- Experiment with removing dairy from your diet.
Milk is already out, but some people feel better without cheese, yogurt, or even heavy cream. (Butter is basically 100% butterfat, and extremely unlikely to cause problems for anyone.) In general, the more butterfat and the less casein and lactose, the less likely it is to cause problems.
Now that you’re sleek, powerful, and dangerous, you’re feeling quite satisfied with yourself. You wake up well-rested, with no aches or pains, and you know yourself capable of stalking, killing, and eating whatever problems the day might bring. Yet you must remain watchful, for an insidious parasite feeds on your pride and saps your strength:
Complacency.
Step 6: Never Stop Hunting
- Push yourself harder and in new ways.
It’s easy to get stuck in an ‘exercise routine’. Explore someplace new. Learn a skill you’re bad at. Throw and catch with your off hand. Try a team sport if you’re a soloist, or a solo sport if you’re a team player. Set goals you’re not already sure you can achieve.
- If you’re going to cheat, cheat with something delicious and portion-limited, or too expensive to eat often.
I’ll eat a Reese’s or drink a Coke before I’ll eat pasta or bread, because they’re individually packaged. Once you open that package of goldfish crackers, they’re all going down the hatch, and we both know it. And I’ll be damned before I’ll completely give up sushi, because I care about toro more than I care about that last 0.1% of bodyfat.
- Be suspicious of all diet advice.
Anyone can write a diet book—and most of them make nutrition complicated so that you’ll keep buying books and going to meetings. Remember that observational studies don’t necessarily tell you whether something is healthy to eat: they tell you whether the healthy people in that study ate that food. Abstracts and conclusions often misrepresent the data. And the comparisons are usually between ‘absolutely terrible’ (refined grains, sugar, trans fats) and ‘less bad’ (whole grains)—which doesn’t mean ‘less bad’ is actually good for you, nor that the culprit in ‘absolutely terrible’ is what they say it is.
- Listen to your body.
Once you’re functioning at a high enough level to tell the difference, you’ll understand what’s helping you and what’s hurting you—not just what’s feeding your addictions. Make individual changes and evaluate their effects before moving on: don’t change too many things at once, or you’ll never know what’s doing what. If you’re physically active, you’ll need some glucose (starch) in your diet to keep your weight stable and your energy level high during severe exertion. And if your body craves a random vegetable, eat it! You might need some micronutrients.
- Your life and health are your own.
You are responsible for them in every respect. Don’t let breathless ‘news’ articles tell you that a new industrial product is your key to better health, or that what humans have eaten for millions of years will kill you. Be suspicious when your government, which spends billions of dollars each year subsidizing agribusiness to grow corn, soy, and wheat, tells you to eat more corn, soy, and wheat. And always remember that ruminants are far better at converting plants into essential fats, complete protein, and bioavailable nutrients than humans—or our factories.
Conclusion: Living Like A Predator
Fatty meats are, quite literally, what made us human. The DHA, complete protein, and sheer calorie density of fatty meat allowed little 65-pound savanna apes with tiny 350cc brains, just smart enough to make rocks sharper by banging them together, to grow into modern humans—with huge 1400cc brains that use a full 20% of the calories we ingest! And we didn’t get fatty meat just by scavenging, because the lions, tigers, wolves, giant hyenas and saber–toothed cats got to it first. We got it by being the most effective predators on Earth.
Now that you’ve been eating like a predator for some time, you are discovering that when you eat like a predator, and play like a predator, you start thinking like a predator. Stupid people aren’t annoyances: they’re profit centers. Fat people are no longer disgusting: they’re delicious. And nothing is more important than being able to trust your packmates, so it’s time to cut loose all the leeches, layabouts, whiners, and malcontents—and it’s long past time to start valuing the solid, dependable people whom you can trust.
You will stop giving your time, love, and strength to those that demand it, and start giving it to those who deserve it. You will understand that ‘love thy fellow man as thyself’ doesn’t apply to someone with his hands in your pockets or his gun in your face, no matter whose authority they claim. You will have compassion for the herd as it moos and bleats, for you were so recently one of them yourself. And you will share your knowledge, because you understand that our real enemies are the predators who hoard this knowledge for themselves, the predators who profit so handsomely from our fear and ignorance—and from our indiscriminate love, whose endgame is the crazy cat lady dead in her condemned house, corpse devoured by the creatures she fed in life.
Now clear those frozen pizzas and Weight Watchers out of your freezer and give them to your fat neighbor, because you are going to the supermarket right now. And you will take a shopping cart, not one of those demure little baskets, because you are going to fill it with heavy, fatty, delicious MEAT.
Live in freedom, live in beauty.

Postscript: More Information
The first objection I hear is always “But…but…you’re eating so much arterycloggingsaturatedfat!” We’ve been lied to for decades: grains and grain products are what’s making us fat, saturated fat is good for you, and cholesterol has been framed for crimes it didn’t commit. Tom Naughton’s “Big Fat Fiasco” (also on youtube) handily debunks these myths, but the science would fill an entire book. (Which Gary Taubes wrote: Good Calories, Bad Calories contains a long history of how the erroneous fat-cholesterol hypothesis took hold of science and government policy—and while I don’t agree that carbohydrates are solely responsible for making us fat, his debunking remains first-rate.)
If you want to understand more of the science behind why I eat the way I do, I recommend Dr. Paul and Dr. Shou-Ching Jaminet’s Perfect Health Diet. (I review it here.)

I hate to link just a few paleo weblogs, because there are so many excellent ones…though for the science behind ‘paleo’ I must give special mention to the following:
Finally, there is a wealth of solid information right here at gnolls.org. I’ve organized my articles by topic in the index…
…and that should be enough information to keep you busy for weeks.
Important! I must note that there is not universal agreement, even among those I’ve linked, on what exactly constitutes ‘paleo’, let alone ‘healthy eating’. I call my approach “functional paleo”—and I define it in detail here, in “What is the Paleo Diet, Anyway?”
