Dr Georges Mouton and the 'System Rebellion' Among Carnivores: A Critical Analysis

Dr Georges Mouton, Carnivore Advocate and the “System Rebellion”: When a Hypothesis Becomes a Certainty
by Laurent Glatz – for Athletic Carnivore

There is a fundamental difference between explaining a biological mechanism and telling a story technical enough to sound like one.

In his latest video, Dr Georges Mouton revisits topics such as dry skin, the thyroid gland, fatty acids, hormones, and micronutrition. Yet, he also manages to circle back to ketogenic and carnivore diets, once again labeling them as “extreme diets.”

The video in question is available here:

It is worth watching in full, precisely because anyone can verify the statements we quote.

Dr Mouton begins by explaining that dry skin is strongly linked to omega-6 fatty acids, mentioning GLA as a “major lubricant,” then elaborates on his nutrigenomic approach. According to him, APOE2, DIO2, and certain AMY1A profiles might predispose some individuals to ketogenic diets.

The problem arises when real mechanisms are transformed into overly assertive clinical conclusions.

Yes, a true deficiency in essential fatty acids can cause skin manifestations. Yes, omega-3 and omega-6 metabolic pathways share some enzymes. Yes, DIO2 is involved in thyroid hormone metabolism.

But none of these elements alone can diagnose the cause of dry skin or determine that a genotype mandates a ketogenic diet.

Then we reach the section directly concerning carnivores.

Dr Mouton explains that reverse T3 can increase during “extreme diets.” He further states that vegans and carnivores often experience a kind of “system rebellion,” because the system essentially says: “I’m missing something.”

This is a striking phrase.

But biologically, what exactly is a “system rebellion”?

No deiodinase enzyme detects that a diet is ideologically “extreme.” Enzymes D1, D2, and D3 respond to physiological states: energy availability, acute illness, inflammation, fasting, hormonal availability, and other metabolic signals.

Therefore, any change in T3 or reverse T3 must be interpreted within this context.

Data on ketogenic diets are far less dramatic. In the study by Iacovides et al., “Could the ketogenic diet induce a shift in thyroid function and support a metabolic advantage in healthy participants?”, the ketogenic diet led to a decrease in T3 and an increase in T4, but without a significant rise in TSH.

In other words, a shift in thyroid profile does not automatically equate to hypothyroidism.

Similarly, in Molteberg et al.’s study on a Modified Atkins diet, T3 and free T3 decreased while free T4 increased, but the rise in reverse T3 was not statistically significant.

Thus, a perfectly reasonable hypothesis exists: some of these changes may represent metabolic adaptation to a different nutritional environment rather than a thyroid gland that is “rebelling.”

Reverse T3 itself deserves more nuance.

In the video, it is described as a kind of inactive “anti-thyroid hormone” that “takes up space.”

This portrayal is highly simplified.

Reverse T3 is essentially an inactive metabolite of T4. Its measurement is not recommended routinely for diagnosing hypothyroidism by major endocrinological guidelines.

Yet Dr Mouton even advises promoters of “extreme diets” to monitor reverse T3.

He then continues with the thyroid, arguing that one must go far beyond TSH alone and practically dismisses the equation “normal TSH, normal thyroid” as a “for dummies” reasoning.

Again, no one claims that TSH diagnoses every pathology of the hypothalamic-pituitary-thyroid axis.

But in an outpatient with a normally functioning axis, it remains the most widely used first-line test to assess thyroid function.

This becomes particularly interesting when we place these claims within Dr Mouton’s publicly documented professional history.

A Background Worth Knowing

In the late 1990s, Georges Mouton worked with professional cyclists.

A specialized website documenting the history of doping in cycling lists him under the nickname “Doctor Syringe” and reports that in 2001 he was prosecuted in a case involving alleged EPO and DHEA-related offenses.

The allegations at the time included forgery and misuse of medical prescriptions, importation and sale of anabolic steroids, abusive medication prescriptions, doping offenses, and illegal pharmaceutical practice.

He spent approximately five months in pretrial detention.

It is crucial to clarify the legal point: Georges Mouton was not convicted for these charges in this Belgian procedure.

In 2008, the Liège criminal court declared the proceedings inadmissible. The case had been initiated following a denunciation by another doctor who had received the athlete’s confidences. The court ruled that this doctor violated professional secrecy, contaminating the procedure.

Therefore, the charges were dismissed without a substantive judgment on the doping accusations.

This distinction is vital: inadmissibility of the procedure does not mean conviction, nor does it mean a full examination followed by acquittal on the materiality of each accusation.

Everyone can draw their own conclusions from this episode. Here, we stick to documented judicial facts.

In England, however, there was a medical sanction.

In 2019, the situation was different.

The BMJ reported that Georges Mouton was suspended for nine months from the UK medical register after a medical tribunal found he had persistently overdiagnosed thyroid problems and treated patients with medications that were not clinically indicated.

The General Medical Council’s allegations concerned eight patients seen between 2013 and 2016.

The case included tests considered unnecessary or insufficiently validated, sometimes without proper consent, as well as interpretations of biological results as revealing thyroid issues.

The tribunal notably examined prescriptions of thyroid hormones in situations where they were not clinically justified.

Why recall this today?

Not to claim that a YouTube video constitutes medical malpractice. We do not make that assertion.

But because in this new video, we find again the thyroid, T3, reverse T3, DIO2, extensive interpretation of tests, iodine, hormones, and a functional medicine approach that Georges Mouton himself describes as “very personal” and “analytical.”

The thematic overlap is a fact.

It is up to the reader to decide the weight they want to give it.

When Personalization Becomes an Authority Argument

The rest of the video is equally revealing.

To treat dry skin, Dr Mouton explains that he can raise DHEA to the upper limit of the reference range.

He then mentions B12: when low, he supplements it, but in the presence of dry skin, he says he can give more.

Then comes iodine, which he claims that pushing it higher “greases the skin.”

Behind these claims lie fragments of perfectly real biology.

DHEA can influence sebum production. B12 can cause acneiform eruptions in some individuals. Excess iodine can also provoke skin manifestations.

But this is precisely where one must distinguish an observed biological effect from a demonstrated therapeutic indication.

The fact that a substance can cause greasier skin or acne does not prove it is relevant to deliberately increase its level to treat dry skin.

This is the entire difference between a physiological hypothesis and medicine based on clinical results.

Be Careful Whom You Trust

Athletic Carnivore does not ask you to blindly believe carnivore, ketogenic, or any nutritionist.

We ask exactly the opposite.

Look at the mechanisms. Look at the studies. Look at the populations studied. And above all, look at how far the data truly allow us to go.

When someone claims that carnivores experience a “system rebellion” because their body feels “something is missing,” simply ask:

Which study demonstrates that the carnivore diet, independent of caloric deficit, illness, or other physiological stress, causes this pathological increase in reverse T3?

When a polymorphism becomes a dietary recommendation, ask where the clinical trials are.

When a value within the normal range must suddenly be “pushed” higher, ask which study shows that this shift improves clinical outcomes.

And when a medical discourse is presented as highly personalized, also look at the documented professional history of the person delivering it.

This is not disparagement.

It is exactly what critical thinking should be: applying the same level of scrutiny to those we agree with and those who challenge us.

The real danger is not following a diet labeled “extreme.”

The real danger begins when we confuse biological plausibility, personal experience, and clinical evidence.

Before entrusting your diet, hormones, or test interpretations to someone, ask yourself one last question:

Have I just been shown something demonstrable, or have I simply been told a biologically appealing story?
