Is Jordan Peterson's carnivore diet really healthy?
Beef, salt, and water is all the Canadian professor eats. Is that sustainable?
- Jordan Peterson began eating an all-beef diet after his daughter's health problems cleared up.
- The human microbiome requires a diversity of nutrients and bacteria, making such a diet questionable in the long-term.
- Neuroses caused by elimination diets could prove to be unhealthier than the ailments they purportedly cure.
Cats are uniquely positioned in the animal kingdom. While they can digest vegetables and other foods — ours love licking the caps of olive and coconut oils, and don't get me started on cheese — these killers were designed to exclusively consume meat. Obligate carnivores need plenty of it for optimal health.
Humans, relatively weak predators for most of history, are equipped with different digestive systems. For example, we need fiber. Yet we're adaptable: we can survive on a stark diversity of nutritive sustenance. From Arctic whale blubber feeders to the equatorial ital vegetarian diet, we turn most anything into food, for better or worse.
Vegans eschew any animal product whatsoever, up to and (sometimes) including honey. At the opposite end of the spectrum are carnivore dieters, or, as their preference has become known, carnivory. Forget low-carb; this clan eats no carbs.
The diet's most famous proponent is probably Jordan Peterson, the Canadian professor who already boasts of a long list of controversial topics in his resume. Inspired by his daughter, Mikhaila, who reportedly recovered from a series of autoimmune problems stemming from juvenile rheumatoid arthritis. According to The Atlantic,
"Some unknown process had triggered her body's immune system to attack her joints. The joint problems culminated in hip and ankle replacements in her teens, coupled with 'extreme fatigue, depression and anxiety, brain fog, and sleep problems.'"
At 15, Mikhaila began an elimination diet, which is arguably the most reliable means for discovering food allergies. Starting with a popular target, gluten, she kept going until all that was left was "beef and salt and water." Noticing his daughter's progress, Peterson began the diet, which he claims helped him shed 50 pounds in seven months.
Joe Rogan - Jordan Peterson's Carnivore Diet Cured His Depression?
Not that he's completely happy about it. While he stopped snoring, overcame autoimmune conditions, shed himself of psoriasis and gingivitis, slept better, cured leg numbness, and threw out his antidepressants, the diet is allegedly "a little hard on your social life."
I concur. When I first met my wife, she tried, gently, as people courting do, to explain why vegans, which I was at that time, are difficult to eat with. Like Peterson, switching to a ketogenic diet cleared up a number of long-standing health conditions. The dietary move also allowed my wife to be less gentle and more honest, the best course of action when discussing emotional issues. Some vegans are difficult to eat with.
Yet so are carnivorists, apparently.
Humans evolved by ingesting and digesting whatever nourishment was at hand. Trial and error — watch enough clansmen die from eating that type of mushroom, don't eat it. An archaic scientific brain emerges: learning through self-reflection. The other perished; I must not follow.
Yet with so many decisions now available we've become paralyzed. With everything right here in this aisle, I'll choose nothing, or just one thing so I don't have think too much about it. Yet thinking always comes, it's what our brains do, with a caveat: it requires justification. This food becomes the focus, so let's make of it a religion.
How Your Gut Influences Your Mental Health: It’s Practically a Second Brain | Dr. Emeran Mayer
Carnivory certainly has its acolytes. Health benefits certainly follow a severe change of diet, if you're eliminating the source of your ailments. Modern humans are carbohydrate junkies. The macronutrient exploits our brain's reward system, especially in the form of sugar. What was once a rare source of pleasure has become the major staple of our diets. Cut that out and you'll be healthier.
What replaces carbs matters. The ketogenic diet holds up in the short-term, but evidence that it's healthy over time is sketchy and sparse. Removing the constant assault by sugar on your microbiome is essential. Relying on beef and salt as the only forms of sustenance, however, looks equally foolish. University of Chicago's Microbiome Center faculty director, Jack Gilbert, breaks it down.
"Your body would start to have severe dysregulation, within six months, of the majority of the processes that deal with metabolism; you would have no short-chain fatty acids in your cells; most of the by-products of gastrointestinal polysaccharide fermentation would shut down, so you wouldn't be able to regulate your hormone levels; you'd enter into cardiac issues due to alterations in cell receptors; your microbiota would just be devastated."
Let me clarify the part about vegans being difficult. Food is a shared experience. The ritual of eating is an important bonding mechanism. There's a reason samosas are Indian and pizzas are Brooklyn: cuisine lives at the intersection of environment and culture. Cultures spring up, in part, from the food they produce and share. It is arguably our most sacred ceremony, as it is what gives us life.
Chefs devote their lives to exploring an infinite palette of flavor profiles. The very few that make their way onto your plate consist of what they believe to be the height of their passion. Then the person you're dining with sends it back because it has soy, or butter, or whatever fad toxin is being eliminated that day.
Joe Rogan - Carnivore Diet Fixed Mikhaila Peterson's Arthritis
We should applaud the creative genius and strong will many chefs displays when branching out into plant-based restaurants. Diversity is the mark of a powerful imagination, one of our brain's unique qualities among the animals. Simultaneously we must recognize the neuroses too much choice has created. An animal that starves itself due to the psychological chains of orthorexia is a creature suffering from the ravages of affluence. Let's not pretend otherwise.
Which can be as unhealthy as a gluten allergy, if not more so. While Mikhaila's body went into remission for eating a few dashes of pepper on a steak for three weeks (or her father's month-long remission from a bit of apple cider vinegar), she can freely drink bourbon and vodka. As James Hamblin writes,
"The idea that alcohol, one of the most well-documented toxic substances, is among the few things that Peterson's body will tolerate may be illuminating. It implies that when it comes to dieting, the inherent properties of the substances ingested can be less important than the eater's conceptualizations of them — as either tolerable or intolerable, good or bad. What's actually therapeutic may be the act of elimination itself."
What is likely toxic to the body is the idea that a particular food is toxic to the body. A 2018 study showed that just thinking you didn't have a protective gene against obesity changed the physiological response of volunteers, causing them to be inclined to eat more. Just as sexual arousal begins in our brains, not our loins, our connection to food is in our heads more than our bellies.
In 12 Rules For Life, Peterson writes that "Order, by contrast, is explored territory." The contrast was chaos, unexplored territory, "the domain of ignorance itself." As Hamblin notes regarding this extreme dieting, restriction brings with it order. Yet what it lost — the pleasure of sharing meals and exploring the world's unique contributions to cuisine — does not seem worth the sacrifice.

How would the ability to genetically customize children change society? Sci-fi author Eugene Clark explores the future on our horizon in Volume I of the "Genetic Pressure" series.
- A new sci-fi book series called "Genetic Pressure" explores the scientific and moral implications of a world with a burgeoning designer baby industry.
- It's currently illegal to implant genetically edited human embryos in most nations, but designer babies may someday become widespread.
- While gene-editing technology could help humans eliminate genetic diseases, some in the scientific community fear it may also usher in a new era of eugenics.
Tribalism and discrimination<p>One question the "Genetic Pressure" series explores: What would tribalism and discrimination look like in a world with designer babies? As designer babies grow up, they could be noticeably different from other people, potentially being smarter, more attractive and healthier. This could breed resentment between the groups—as it does in the series.</p><p>"[Designer babies] slowly find that 'everyone else,' and even their own parents, becomes less and less tolerable," author Eugene Clark told Big Think. "Meanwhile, everyone else slowly feels threatened by the designer babies."</p><p>For example, one character in the series who was born a designer baby faces discrimination and harassment from "normal people"—they call her "soulless" and say she was "made in a factory," a "consumer product." </p><p>Would such divisions emerge in the real world? The answer may depend on who's able to afford designer baby services. If it's only the ultra-wealthy, then it's easy to imagine how being a designer baby could be seen by society as a kind of hyper-privilege, which designer babies would have to reckon with. </p><p>Even if people from all socioeconomic backgrounds can someday afford designer babies, people born designer babies may struggle with tough existential questions: Can they ever take full credit for things they achieve, or were they born with an unfair advantage? To what extent should they spend their lives helping the less fortunate? </p>
Sexuality dilemmas<p>Sexuality presents another set of thorny questions. If a designer baby industry someday allows people to optimize humans for attractiveness, designer babies could grow up to find themselves surrounded by ultra-attractive people. That may not sound like a big problem.</p><p>But consider that, if designer babies someday become the standard way to have children, there'd necessarily be a years-long gap in which only some people are having designer babies. Meanwhile, the rest of society would be having children the old-fashioned way. So, in terms of attractiveness, society could see increasingly apparent disparities in physical appearances between the two groups. "Normal people" could begin to seem increasingly ugly.</p><p>But ultra-attractive people who were born designer babies could face problems, too. One could be the loss of body image. </p><p>When designer babies grow up in the "Genetic Pressure" series, men look like all the other men, and women look like all the other women. This homogeneity of physical appearance occurs because parents of designer babies start following trends, all choosing similar traits for their children: tall, athletic build, olive skin, etc. </p><p>Sure, facial traits remain relatively unique, but everyone's more or less equally attractive. And this causes strange changes to sexual preferences.</p><p>"In a society of sexual equals, they start looking for other differentiators," he said, noting that violet-colored eyes become a rare trait that genetically engineered humans find especially attractive in the series.</p><p>But what about sexual relationships between genetically engineered humans and "normal" people? In the "Genetic Pressure" series, many "normal" people want to have kids with (or at least have sex with) genetically engineered humans. But a minority of engineered humans oppose breeding with "normal" people, and this leads to an ideology that considers engineered humans to be racially supreme. </p>
Regulating designer babies<p>On a policy level, there are many open questions about how governments might legislate a world with designer babies. But it's not totally new territory, considering the West's dark history of eugenics experiments.</p><p>In the 20th century, the U.S. conducted multiple eugenics programs, including immigration restrictions based on genetic inferiority and forced sterilizations. In 1927, for example, the Supreme Court ruled that forcibly sterilizing the mentally handicapped didn't violate the Constitution. Supreme Court Justice Oliver Wendall Holmes wrote, "… three generations of imbeciles are enough." </p><p>After the Holocaust, eugenics programs became increasingly taboo and regulated in the U.S. (though some states continued forced sterilizations <a href="https://www.uvm.edu/~lkaelber/eugenics/" target="_blank">into the 1970s</a>). In recent years, some policymakers and scientists have expressed concerns about how gene-editing technologies could reanimate the eugenics nightmares of the 20th century. </p><p>Currently, the U.S. doesn't explicitly ban human germline genetic editing on the federal level, but a combination of laws effectively render it <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">illegal to implant a genetically modified embryo</a>. Part of the reason is that scientists still aren't sure of the unintended consequences of new gene-editing technologies. </p><p>But there are also concerns that these technologies could usher in a new era of eugenics. After all, the function of a designer baby industry, like the one in the "Genetic Pressure" series, wouldn't necessarily be limited to eliminating genetic diseases; it could also work to increase the occurrence of "desirable" traits. </p><p>If the industry did that, it'd effectively signal that the <em>opposites of those traits are undesirable. </em>As the International Bioethics Committee <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">wrote</a>, this would "jeopardize the inherent and therefore equal dignity of all human beings and renew eugenics, disguised as the fulfillment of the wish for a better, improved life."</p><p><em>"Genetic Pressure Volume I: Baby Steps"</em><em> by Eugene Clark is <a href="http://bigth.ink/38VhJn3" target="_blank">available now.</a></em></p>
Meteorologists propose a stunning new explanation for the mysterious events in the Bermuda Triangle.
One of life's great mysteries, the Bermuda Triangle might have finally found an explanation. This strange region, that lies in the North Atlantic Ocean between Bermuda, Miami and San Juan, Puerto Rico, has been the presumed cause of dozens and dozens of mind-boggling disappearances of ships and planes.
