The Guru Industrial Complex

How Berg, Huberman, and Sinclair Sold Me My Own Health Back

There are six bottles on my shelf. Vitamin C. Vitamin D. Magnesium. Fish Oil. Probiotics, and zinc. I take them every day. I can tell you what each of them does. I can tell you why I take them. What I can’t tell you is how I got here.

I mean, I know the sequence. Originally, I started with more bottles than this. CoQ10. Garlic capsule. Apple cider vinegar... A few others I can’t even recall anymore. What I do know is I learned about them from a man on YouTube. I listened, didn’t ask a lot of questions, and the reason I didn’t ask is the same reason millions of others aren’t asking: he has “Dr.” in front of his name.

Dr. Eric Berg. Fourteen million YouTube subscribers. Keto. Intermittent fasting. Supplement stacks for everything from sleep to thyroid function. He speaks with the calm authority of a man who’s distilled the science down for you, the grateful viewer, who just needed someone to tell them how to be healthy. I followed his recommendations. I fasted. I took the supplements. I adjusted my diet. Some of it worked. Some of it I couldn’t tell. But it felt like progress because a doctor was guiding me.

Except he wasn’t a doctor.

Berg is a chiropractor. He’s a D.C, not an M.D. In 2007, the Virginia Board of Medicine reprimanded him for practicing outside his scope. For making unsubstantiated therapeutic claims about treating everything from allergies to depression to infertility. He was fined a mere fifteen hundred dollars.

He took the fine. Then started a YouTube channel and scaled the same playbook to millions of people.

Then came Andrew Huberman.

If Berg was the friendly neighborhood doctor, Huberman was the real thing. Or so I thought. Associate professor of neurobiology and ophthalmology at Stanford School of Medicine. The Huberman Lab podcast. Third most popular show on Spotify in 2023. Recommended by friends, and I remember thinking: this is different. This is an accredited Stanford professor.

I tried some of his recommendations. Started doing his morning sunlight walk. Followed protocols he delivered with the sincerity of a disciplined, measured expert. Optimized and evidence-based.

Then I did a little digging.

I discovered that scientists criticized him for speaking with certainty across health domains far outside his expertise: the visual system. Not nutrition. Eyes.

I learned I was taking advice from a man who once said he was as scared of sunscreen as he was of melanoma. A man who admitted avoiding flu vaccines despite acknowledging that they work. Meanwhile his partnership with Momentous, a supplement company, was churning millions. Scientific recommendations attached to a shopping cart.

Then the New York Magazine reported that the apostle of discipline was maintaining at least five simultaneous relationships with most of the women believing they were his only partner. His lab at Stanford barely existed anymore. His partnership with AG1, where he served as scientific advisor, kept running even after its founder resigned over a criminal conviction for a rent-to-buy scheme that targeted low-income clients.

Then there’s David Sinclair. He makes Berg and Huberman look like amateurs. I first heard of him on Steven Bartlett’s Diary of a CEO. (One of those interview platforms where every guest sounds like they’re about to save the world). Sinclair was a tenured professor at Harvard Medical School with over five hundred published papers. He talked about longevity, about molecules that could reverse aging, and I did what I always did. Took notes.

In 2008, GlaxoSmithKline bought his company for $720 million based on research into resveratrol, a compound that “activated longevity genes” found in red wine. Then researchers couldn’t reproduce his results. Glaxo’s own scientists had warned against the deal. The science collapsed. So Sinclair pivoted to a new molecule. Same playbook. Went on Joe Rogan’s podcast, wrote a bestseller, and watched 2,100 tons of the new molecule supplement, NMN flood into the country with his name. His colleagues eventually called him a snake oil salesman. He was forced to step down from the longevity institute he’d founded. But Harvard had taken its cut of every patent, every deal and every dollar.

Five hundred papers. Harvard tenure. The most credentialed figure on this list, and the science was junk.

What cracked it open for me wasn’t a health guru. It was Celsius. A crypto lending platform. The CEO Alex Mashinsky radiated the same calm authority every other figure on this list did. He appeared on podcasts, YouTube channels, Twitter, conferences... Trust the math. Banks suck. Control your money. Trust me.

I trusted his platform with a little over two thousand dollars.

In June 2022, Celsius froze all withdrawals. Internal documents described the operation as “very Ponzi-like.” Mashinsky had been secretly dumping $44 million of the company’s own token while telling everyone to hold.

He plead guilty and got 12 years.

Two thousand dollars isn’t life-changing money. It’s still a lot, but some lost millions. I did lose something else: the belief that confidence and being right, or truthful were the same thing. Once that cracked, it was hard not to see it everywhere.

I started looking at Berg differently. Then Huberman. Then Sinclair. Not because they were all running Ponzi schemes. But because the mechanism was the same: a person I’d never met, speaking into my ear through a screen, and me trusting them.

Here’s what makes this harder than a simple story about con men.

Some of their advice worked.

I didn’t fast because Berg told me to. I fasted because I used to do it in my early 20s, long before Berg and YouTube. I’d read about it in Taoist texts. The tradition of bigu, grain avoidance as purification, a practice documented as far back as 168 BCE. I didn’t know the science. I just knew what happened to my body when I did it. The first 24 hours is rough. But by hour forty-eight, something shifts. I felt clear. Light. Present.

The science, for what it’s worth, partially backs it up. Which is exactly where the guru operates: take a partial truth, strip the caveats, and present it as a revelation.

Berg didn’t teach me to fast. He repackaged something I already carried and sold it back to me with a “Dr.” in front of it.

The magnesium works. It helps me sleep. I still take it. But I can’t genuinely remember whether I discovered that on my own or whether Berg told me first. That’s the uncertainty I can’t resolve. Was it him or me? When your source is discredited, what happens to what works? Do I throw away the magnesium because the man who recommended it was fined for bad practice? Or do I keep taking it and accept the boundary between what I know and what the guru influenced is blurred?

I kept the magnesium. But I don’t pretend the line is clean.

What bothers me isn’t them. It’s us. It’s me.

I’m not angry at Berg, Huberman, or Sinclair. They did what the market rewards them for doing. That market is us. We’re the ones who needed a Stanford neuroscientist to tell us to take a morning walk. We’re the ones who needed a Harvard geneticist to tell us a glass of red wine could make us live forever.

And I wasn’t just the market. I was the marketing. I shared Steven Bartlett’s Diary of a CEO episodes with friends. I recommended Celsius to a friend who invested. That felt awful. I was a node in the distribution network. Feeding the guru pipeline to others. Bartlett interviews the “experts,” the experts validate Bartlett. The audience validates both. And I was sending links, doing the delivery for free.

The wiring is ancient. Humans always look for the confident voice. The tribal leader, the healer, the elder who is wise and all knowing. Evolution built us for small groups where the person giving the advice has skin in the game. They lived in your village. They ate the same food. Their children played with yours. If they led you down a bad path, they suffered the same consequences you did.

The internet and podcasts destroyed that. Now confident voices reach millions, and the speaker has no skin in the game. Mel Robbins another self-help guru, with her millions of followers doesn’t know you. In every one of her podcasts she tells you, “I love you.” She can’t love you. Love requires two people who have met. But she’s mapped Bernays’s Propaganda—written in 1928—onto her podcast with such precision that millions of people believe they have a friend named Mel.

After Celsius, Berg, all of it, I stopped. Now I hear recommendations and instead of adding it to my cart, I pause and ask if I’m being sold to. I trust no one. Which sounds like a line from conspiracy theorists. The guru industrial complex doesn’t just exploit trust. It poisons the well. Every credential now triggers the question: what are they selling me? I do my own research now. Which is the rallying cry of every anti-vaxxer and flat-earther on the internet. Which is sad, because we are social animals. We need to trust someone. A world where everyone is their own expert is just a different kind of chaos.

I still fast occasionally. But not because a guru tells me to. I do it because a twenty-two-year-old kid reading Taoist texts in his apartment felt something change in himself after 48 hours, and never forgot. That knowledge was mine before any guru tried to sell it back to me.

But I take the Magnesium too. And honestly, I don’t remember if that’s mine or theirs.

The most honest thing I can say about the guru industrial complex is it doesn’t sell you answers. It undermines questions. After you’ve listened to the confident voice long enough, you can’t always tell the difference between what you know and what you’re being sold. Between what you discovered on your own and what they’ve planted.

Six bottles on my shelf. I can tell you what each one does.

What I can’t promise you is that any of it was my idea.
