Dr. Steven Gundry Evaluation: factchecking his claims.

I needed to watch quite a lot 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 loss plan books, together with The Plant Paradox. You’ve positively seen his adverts on social media.

Right here’s the factor. Steven Gundry is a reliable medical physician, and like just a few different MDs within the wellness sphere. However he appears to be targeted 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 quite a lot of what he says is simply plain incorrect. Not solely that, however lots of his claims are simply verifiable. It’s simply that most individuals don’t wish to or don’t understand how to try this.

Crucial pondering, 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 bother – deliberately or not – with these issues.

Gundry’s adverts are like cockroaches. Even if you happen to click on ‘cover,’ they’re inconceivable to eliminate as a result of they’re posted from no fewer than 9 totally different accounts:

Gundry MD, Dr. Gundry Vitality and Well being, Dr. Steven Gundry, Gundry MD – Diet, Gundry MD – Complete 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 evaluation right here.

The movies normally 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 techniques (ACT NOW! SUPPLIES ARE LIMITED!). Lots of them have titles or photos .(burning eggs??) which are unrelated to the content material throughout the video

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

Similar 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 a giant reveal 
  • The phantasm that he’s doing us a favor by telling us a particular secret that no one else is aware of
  • Calling adverts ‘shows’ and ‘movies’ 
  • An attraction to nature by touting ‘pure’ elements in what quantity to be ineffective dietary supplements

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

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

Plenty 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 worry as a driver for clicks and gross sales in nearly all the things he writes and publishes. 

What are lectins?

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

In line with 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 acquired most cancers as a teen as a result of she was consuming the fallacious issues? 

Leaky intestine isn’t an precise medical analysis. It’s typically utilized by different drugs practitioners to explain elevated intestinal permeability. However these practitioners normally blame ‘leaky intestine’ for all kind 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 after they eat gluten. That is very totally different from Gundry’s declare that X meals trigger EVERYONE’S guts to be ‘leaky.’

Gundry additionally claims that lectins trigger us to achieve 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 largely destroyed by cooking. And since no one is consuming uncooked kidney beans or rice, we don’t have to fret. 

The Blue Zone populations of of the world devour 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 precipitated their longevity, and that simply because they dwell longest doesn’t imply they’re wholesome and glad.

Science says in any other case.

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

Autoimmune ailments aren’t essentially attributable to 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 kind of overreach that appears fully regular for Gundry.

Gundry tells us that lectins, specifically 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 completed.

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, fully unrelated research…you get the purpose. He has been referred to as out for his deceptive use of analysis and the way in which he twists science, nevertheless it’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 principle 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.

Incorrect once more, Dr. Steven Gundry.

In all probability in an try and garner credibility for this principle, Gundry says he has misplaced 70 kilos on his lectin-free weight loss plan. He claims that lots of his sufferers have misplaced weight on his plan by making no modifications to their diets apart from 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 end in weight reduction is simply too good for individuals to go up, and Gundry is aware of that. 


There’s completely no science behind Gundry’s weight reduction principle, and there’s no potential mechanism behind it, both. For almost all of individuals, lectins don’t hurt the intestine lining, they usually 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 completed on his lectin-free weight loss plan, though he appears to have had ample time and clinic topics at his disposal to do one.

If individuals drop pounds on the lectin-free weight loss plan, it’s as a result of they’ve lower 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. 

A terrific 2020 examine by Kevin Corridor et al confirmed that ultra-processed meals – which embody refined grains reminiscent of corn, soy, and wheat – contribute considerably to weight acquire attributable to better vitality availability in these meals.

Gundry’s weight loss plan prohibits meals containing these elements, so many individuals on this weight loss plan will find yourself consuming much less general. They may drop pounds, nevertheless it has nothing to do with the lectins.

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

Avocado, figs, coconut, raspberries, and inexperienced banana, largely. 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 possible’ 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 are offered in North America are papayas, Arctic Apples, and pink pineapples. But yet one more manner Gundry stokes worry unnecessarily (additionally: GMOs have by no means been proven to be dangerous to people).

Gundry’s content material contains him calling bananas, ‘essentially the most harmful well being meals.’ That is fully ridiculous, however I suppose it’s constant along with his understanding of diet.

Let’s be sensible right here: most individuals in North America don’t devour quite a lot of lectins, as a result of most of us don’t even come near consuming sufficient crops. It’s fairly disgusting that Gundry is, in a passive-aggressive manner, discouraging individuals from including extra crops into their diets. 

Some individuals – particularly individuals with IBS – might not tolerate lectin-containing meals. This can be due to the lectins, or it could 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 nicely.

Most of us do tolerate lectin meals nicely, and right here’s a shock: the fibre in these meals really feeds our intestine micro organism and might strengthen the intestine lining, not destroy it. So when a physician makes a blanket suggestion to keep away from meals which are in any other case often called a number of the healthiest on this planet, it ought to instantly elevate a purple flag for you. 

Dr. Steven Gundry dietary supplements

Gundry’s adverts are primarily targeted 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 loss plan?

Complete Restore, Lectin Protect, and BioComplete appear to be Gundry’s bread-and-butter merchandise which are marketed essentially the most. 

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

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

dr steven gundry diet

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

It’s attention-grabbing to notice that BioComplete 3 comprises sunflower oil, which Gundry claims is ‘loaded with lectins.’ 

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

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

Glutamine, an ingredient in Complete Restore, is understood 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’s nothing past anecdotal proof that that is true. Glutamine is an amino acid, and like all protein, might enhance satiety. However once more, within the minuscule dose that TR comprises? In all probability not.

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

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

I can also’t write a chunk on Gundry with out together with one thing concerning the kerfuffle that the superb Dr. Jen Gunter had with him and Goop just a few years again. If you happen to’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 loss plan is that they’re all a complete waste of time, cash, and vitality.

It appears as if nearly each single piece of content material that Gundry posts has the target of stoking worry and anxiousness whereas concurrently making a living by his ‘cures.’

He’s like a shady salesman, spreading misinformation and worry 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 loss plan, have ever been correctly studied for the results he claims they’ve, and there’s one thing actually particular – in a foul manner, thoughts you – a few licensed doctor who spreads half-truths and BS as in the event that they’re truth, all whereas milking all of it to line his pockets.
