Dr. Steven Gundry Evaluate: factchecking his claims.

I needed to watch a number of Gundry MD movies for this put up. They put me into a very unhealthy temper.

Who’s Dr. Steven Gundry?

Steven Gundry is a California-based heart specialist and creator of a number of weight-reduction plan books, together with The Plant Paradox. You’ve undoubtedly seen his adverts on social media.

Right here’s the factor. Steven Gundry is a professional medical physician, and like a couple of different MDs within the wellness sphere. However he appears to be centered on making gross sales versus really serving to individuals with their well being.

That’s a daring declare, I do know – however I simply can’t get behind the thought {that a} medical physician like Gundry doesn’t know that a number of what he says is simply plain incorrect. Not solely that, however a lot of his claims are simply verifiable. It’s simply that most individuals don’t wish to or don’t understand how to do this.

Vital considering, interpretation of analysis, the understanding that cell research don’t extrapolate to people – they’re all abilities that MDs ought to have.

Sadly although, a few of these docs *ahem* Hyman *ahem* Gundry *ahem* Oz *ahem* appear to have some hassle – deliberately or not – with these issues.

Gundry’s adverts are like cockroaches. Even in case you click on ‘disguise,’ they’re unimaginable to do away with as a result of they’re posted from no fewer than 9 completely different accounts:

Gundry MD, Dr. Gundry Vitality and Well being, Dr. Steven Gundry, Gundry MD – Diet, Gundry MD – Whole Restore, Gundry MD – Vitality Renew, Gundry MD – Bio Full 3, Gundry MD – Bioskin, and Gundry MD Metabolic Superior. 

There’s a definite incongruence between Gundry’s MD credential, which is one thing that’s extremely revered, and his adverts, that are as spammy as those from VShred.

Learn my VShred overview right here.

The movies often begin with a ridiculous, clickbaity hook like, ‘NEVER EAT THESE THREE FOODS!’ and find yourself being round an hour in size, full with doubtful claims and high-pressure gross sales ways (ACT NOW! SUPPLIES ARE LIMITED!). Lots of them have titles or photographs .(burning eggs??) which might be unrelated to the content material throughout the video

Who the heck needs to look at an hour-long advert?

Identical to The Plant Paradox, Gundry’s gross sales pitch has each purple flag that ever existed:

  • A disclosure that meals you beforehand thought was wholesome, are literally not
  • Concern-mongering language
  • A gross sales pitch for his personal dietary supplements
  • The promise of an enormous reveal 
  • The phantasm that he’s doing us a favor by telling us a particular secret that no person else is aware of
  • Calling adverts ‘displays’ and ‘movies’ 
  • An attraction to nature by touting ‘pure’ substances in what quantity to be ineffective dietary supplements

I believe it goes with out saying that an individual or firm that employs all the above strategies to attempt to get you to purchase one thing, is an individual or firm that you simply shouldn’t take note of.

Let’s check out a few of Steven Gundry’s claims and merchandise.

Quite a lot of what Gundry places on the market revolves round his disdain for lectins, which he calls ‘plant toxins.’ I assume that title makes lectins appear scarier, which is nice for Gundry’s backside line.

He seems to make use of concern as a driver for clicks and gross sales in nearly every thing he writes and publishes. 

What are lectins?

Lectins are proteins which might be produced by vegetation as a pure defence. They’re additionally in a number of different meals we eat – eggs and meats included. The best quantities of lectins are in grains and legumes, which in fact Gundry tells us to keep away from.

In response to Gundry, lectins trigger leaky intestine, which he believes is the reason for all sickness. ‘All illness begins within the intestine,’ he says, which isn’t solely far-fetched, it has by no means been confirmed.

Let’s see, my buddy received most cancers as a teen as a result of she was consuming the improper issues? 

Leaky intestine isn’t an precise medical prognosis. It’s typically utilized by different medication practitioners to explain elevated intestinal permeability. However these practitioners often blame ‘leaky intestine’ for all type of diseases which have by no means been conclusively proven to be a results of it.

The one exception is in individuals with celiac illness, whose intestinal permeability will increase once they eat gluten. That is very completely different from Gundry’s declare that X meals trigger EVERYONE’S guts to be ‘leaky.’

Gundry additionally claims that lectins trigger us to realize weight, damage our kidneys, and trigger irritation and autoimmune illness.

None of that is even remotely appropriate. As with most of his concepts, Gundry is working off of hypotheses that he himself dreamed up.

Fortunately for us, lectins are principally destroyed by cooking. And since no person is consuming uncooked kidney beans or rice, we don’t have to fret. 

The Blue Zone populations of of the world eat copious quantities of lectin-containing meals, however are the healthiest and longest-living individuals on the planet. When requested about this, Gundry implied that the ‘antioxidants’ of their diets brought on their longevity, and that simply because they dwell longest doesn’t imply they’re wholesome and blissful.

Science says in any other case.

Mountains of analysis (right here) (right here) additionally suggests {that a} weight-reduction plan that’s plant-heavy is the healthiest solution to eat. It’s a widely known proven fact that plant-based diets really lower irritation. 

Autoimmune illnesses aren’t essentially brought on by elevated intestine permeability; We really don’t know in the event that they’re the results of this situation, or in the event that they’re a symptom. That is the type of overreach that appears utterly regular for Gundry.

Gundry tells us that lectins, particularly agglutinin from grains, mimic insulin and trigger diabetes. His supply for this declare?

A 1973 examine on fats cells. As in, fats cells in a lab dish, not fats cells residing in precise people. The analysis used extra agglutinin than anybody would eat, and outcomes have by no means been replicated in people within the nearly 50 years for the reason that examine was carried out.

That Gundry makes use of this examine to ‘show’ his claims isn’t a shock: a lot of the analysis he cites to again his theories up are animal research, cell research, previous research, utterly unrelated research…you get the purpose. He has been known as out for his deceptive use of analysis and the best way he twists science, but it surely’s like water off a duck’s again.

A screenshot of Gundry’s YouTube. Embarrassing.

So far as his ‘lectins trigger weight problems’ declare, this comes from Gundry’s concept that the leaky intestine from lectins results in hormonal shifts that trigger weight acquire. 

Gundry claims that lectins breach the intestinal barrier and set off our immune system, inflicting irritation. This irritation triggers ‘fats storage hormones’ that then trigger us to retailer fats and acquire weight.

Mistaken once more, Dr. Steven Gundry.

In all probability in an try and garner credibility for this concept, Gundry says he has misplaced 70 kilos on his lectin-free weight-reduction plan. He claims that a lot of his sufferers have misplaced weight on his plan by making no adjustments to their diets in addition to eliminating lectins.

That is malarkey, however lots of people are searching for a magical, work-free methodology to drop kilos. The promise of 1 easy change that may lead to weight reduction is simply too good for individuals to cross up, and Gundry is aware of that. 


There’s completely no science behind Gundry’s weight reduction concept, and there’s no attainable mechanism behind it, both. For almost all of individuals, lectins don’t hurt the intestine lining, and so they definitely haven’t been proven to imitate insulin and trigger fats storage.

Once more, Gundry’s ‘proof’ for this declare is that 1973 examine. No research have been carried out on his lectin-free weight-reduction plan, regardless that he appears to have had ample time and clinic topics at his disposal to do one.

If individuals shed weight on the lectin-free weight-reduction plan, it’s as a result of they’ve reduce energy. That’s not unimaginable, since Gundry’s plan eliminates total meals teams. No extra grains, little or no fruit  (which Gundry calls, ‘poisonous sweet’), and no legumes. 

An awesome 2020 examine by Kevin Corridor et al confirmed that ultra-processed meals – which embrace refined grains equivalent to corn, soy, and wheat – contribute considerably to weight acquire resulting from better power availability in these meals.

Gundry’s weight-reduction plan prohibits meals containing these substances, so many individuals on this weight-reduction plan will find yourself consuming much less general. They may shed weight, but it surely has nothing to do with the lectins.

Which fruits are allowed on the lectin-free weight-reduction plan?

Avocado, figs, coconut, raspberries, and inexperienced banana, principally. Gundry additionally cautions us that fruit that’s not in-season shouldn’t be consumed.

He claims that ‘the continual availability of fruit is among the greatest contributors to the weight problems disaster,’ as if everyone seems to be getting fats from consuming fruit.

This declare alone demonstrates how extremely misplaced Gundry is. 

dr steven gundry reviews

He provides that fruits now have extra lectins than they used to, and that our fruits are ‘extra seemingly’ to be GMO, which he says are ‘new organisms, not present in nature.’

I’m going to step in right here and say that the one GMO fruits which might be offered in North America are papayas, Arctic Apples, and pink pineapples. But yet one more method Gundry stokes concern unnecessarily (additionally: GMOs have by no means been proven to be dangerous to people).

Gundry’s content material consists of him calling bananas, ‘probably the most harmful well being meals.’ That is utterly ridiculous, however I suppose it’s constant together with his understanding of diet.

Let’s be reasonable right here: most individuals in North America don’t eat a number of lectins, as a result of most of us don’t even come near consuming sufficient vegetation. It’s fairly disgusting that Gundry is, in a passive-aggressive method, discouraging individuals from including extra vegetation into their diets. 

Some individuals – particularly individuals with IBS – could not tolerate lectin-containing meals. This can be due to the lectins, or it might be as a result of the meals with the very best lectin content material are additionally the meals with the very best FODMAP content material as effectively.

Most of us do tolerate lectin meals effectively, and right here’s a shock: the fibre in these meals really feeds our intestine micro organism and may strengthen the intestine lining, not destroy it. So when a health care provider makes a blanket advice to keep away from meals which might be in any other case often called among the healthiest on the earth, it ought to instantly increase a purple flag for you. 

Dr. Steven Gundry dietary supplements

Gundry’s adverts are primarily centered on his dietary supplements, most of which tie in with the ‘leaky intestine is making us all sick’ narrative. 

Did I point out that it’s a purple flag when somebody sells dietary supplements to associate with their weight-reduction plan?

Whole Restore, Lectin Protect, and BioComplete appear to be Gundry’s bread-and-butter merchandise which might be marketed probably the most. 

Lectin Protect is 100% a money-grab for unsuspecting individuals who consider that lectins are so poisonous, that they should pull each single little bit of them out of their weight-reduction plan. Don’t fall for this.

BioComplete is an overpriced pre/professional/put up biotic that accommodates Tributyrin, Sunfiber, and lactobacillus. Whereas it might or will not be efficient, the claims which might be made about BioComplete are absolute f*ckery.

dr steven gundry diet

Not one of the substances in BioComplete have ever been proven by professional science to scale back cravings, assist with weight reduction, and enhance power. It really boggles my thoughts as to the way it’s authorized to make these kinds of claims.

It’s fascinating to notice that BioComplete 3 accommodates sunflower oil, which Gundry claims is ‘loaded with lectins.’ 

I assume his personal suggestions change when one thing is making him cash. 

Whole Restore is one other overpriced Gundry product that purportedly ‘promotes a wholesome intestine lining.’

Glutamine, an ingredient in Whole Restore, is thought for having a optimistic impact on the intestine. However that’s in dosages of 5-45g, not the 213mg that’s on this complement. 

steven gundry quack

Gundry additionally says that glutamine can cut back ‘junk meals cravings,’ however there may be nothing past anecdotal proof that that is true. Glutamine is an amino acid, and like every protein, could enhance satiety. However once more, within the minuscule dose that TR accommodates? In all probability not.

You understand what does assist with the intestine lining? Fibre. The type we get from complete grains, starchy and non-starchy greens, legumes, and fruit.

This whole Gundry model is a dumpster fireplace racket. And I’m not right here for it.

I can also’t write a bit on Gundry with out together with one thing in regards to the kerfuffle that the superb Dr. Jen Gunter had with him and Goop a couple of years again. In the event you’re searching for extra proof of Gundry’s character, right here it’s.


The underside line on Gundry and his adverts and his dietary supplements and weight-reduction plan is that they’re all a complete waste of time, cash, and power.

It appears as if nearly each single piece of content material that Gundry posts has the target of stoking concern and nervousness whereas concurrently creating wealth by his ‘cures.’

He’s like a shady salesman, spreading misinformation and concern to promote ineffective merchandise whereas utilizing his MD credential for credibility. His adverts are embarrassing and spammy, and so is his behaviour.

None of his dietary supplements, or his weight-reduction plan, have ever been correctly studied for the results he claims they’ve, and there’s one thing actually particular – in a foul method, thoughts you – a few licensed doctor who spreads half-truths and BS as in the event that they’re reality, all whereas milking all of it to line his pockets.
