If they pull that long spiel thing that you’re describing, I pretty will already dismiss them as a quack. You don’t need tactics like that if you have evidence on your side. The purpose of the tactic is to weed out the people who would be incredulous, and to deepen the pull in those interested, in the same way TV shows can get you to keep watching with cliffhangers even if you’re starting to lose interest or want to call it a night. ---

Interesting that you posted this today as I saw a ‘story’ of his on Instagram this morning. I did watch. It was the one about leaky gut saying how lectins are bad and that prebiotics and probiotics are what is needed. His jar of whatever it is was $69.95 but for just today $49.95 but if you buy 3 then $44.95 each. You are right that he is a very good marketer but I passed. ---

Leaky gut seems like it should be a relatively easy thing to test for. Are there more of these other chemicals (or their byproducts) in the blood stream of people who purportedly have this syndrome? Do the numbers notably go up when they consume these foods, at higher rates than a control group? And, when they do the biopsy to detect intestinal absorption problems, do they see the reported affects in the biopsied tissue? ---

It’s remarkable to see that our culture has no ability to internalize this kind of bogus nonsense - these long form “infomercials” for snake oil have been going on since the dawn of time and yet they still feature prominently in such skeptical discussions as the august Straight Dope! ---

> [@ParallelLines](#): > > because while I’ve seen said links (and went back and checked and at least one was indeed Gundry) I doubt that most of us do anything different than @kenobi_65 for example and tune the crap out without ever being aware of who the pusher was. Right. I may have seen the clickbait a thousand times and just let it sit there on screen w/o checking out what/who. Only became really aware of “Dr. Gundry” barely weeks ago because of an otherwise entirely separate online item where a public figure mentioned eating/avoiding foods from “Dr. Gundry’s list” among a number of other things that have helped her well-being, and one of the commenters posted details. ---

It might be a bit of a challenge to keep from eating any of them, but if you die suddenly tomorrow, don’t say Steven didn’t warn you. He’s a quack, but the diet he advocates for isn’t that odd. Take a close look at the foods on that list. It’s mostly grains and refined sugars, plus the nightshade vegetables. If you read one of his books (he has several, but they’re all very similar), what he advocates for is to eat mostly vegetables, minus the aforementioned grains, simple sugars, and nightshades, and supplementing with seafood or poultry once or twice a week. In particular he doesn’t advocate for the stereotypical keto ingredients like red meat or other processed foods high in saturated fats. In other words, he hides the quackery behind a diet that seems reasonable, which IMHO is how he’s gained a large following. ---

> [@FlikTheBlue](#): > > He’s a quack, but the diet he advocates for isn’t that odd. Take a close look at the foods on that list. It goes beyond “odd” to urge people to avoid such an exhaustive list of healthy foods, including pasta, rice, potatoes, milk (and a wide range of dairy products), bread, bananas, blueberries and a huge number of other fruits and vegetables (there aren’t many left to choose from once Gundry gets through demonizing them), nuts, seeds and plant oils on the basis of a theory lacking in supporting evidence and rejected by the vast majority of physicians and diet experts. It’s not as though Gundry is the only crank to have successfully monetized weird dietary advice and built up a business selling dubious supplements and books. Joe Mercola and Mike Adams (of Natural News infamy) have harvested gullible clients in similar fashion. Gundry’s recent foray into antivax advocacy follows in their rancid footsteps. Mainly, I’m just tired of seeing his finger-wagging clickbait promos. ---

Very good article, thanks. Interesting how often the same themes crop up among these diet gurus. Perlmutter co-wrote one of his brain books with a “medical anthropologist and shaman” and claimed that of his “miracle” cures, “Virtually all of these patients were somehow connecting with what the shaman had referred to as the Great Spirit.” It’s great if your treatments open up a portal to “the Great Spirit” - but even better if _you_ are the Great Spirit. Recently, one of Perlmutter’s buddies, supplement pusher Joe Mercola (who has his own list of [Foods You Should Never Eat](http://mcgill.ca/oss/article/food-health-news/joe-mercola-and-foods-you-should-never-eat)), came under the spell of an adviser calling himself Bahlon, severed ties with old allies and [began referring to himself as the new Jesus](https://www.respectfulinsolence.com/2024/02/16/quack-tycoon-joe-mercola-now-thinks-hes-the-new-jesus-who-will-save-the-world/). We can laugh, but these people are still revered by millions of followers. ---
