My mission: reversing the irreversible

Share

Every year, I get a full-body MRI. And every year, I hear the same comments: “It’s a waste of money.” “There are too many false positives.” “If you don’t have symptoms, there’s nothing to do.” “You’re getting way too much information from all these tests.”

The false positive argument is, in my opinion, the weakest of all. A false positive means a moment of worry, followed by a few extra tests that give you exactly the information you were missing. Compare that with a real finding caught early, which can change everything. These scans can literally save your life.

July 2023: Where It All Started

On my very first full-body MRI, the radiologist found 15 small white spots in my brain. I was told that 3 or 4 would be completely normal. But 15? That’s a lot.

At the time, the report called them “ischemic lesions.” When I showed the scan to a French neurologist, he called them “microangiopathy.” Two different words for what I was looking at. It isn’t always easy being a patient when even doctors don’t use the same language!

In fact, both terms point to the same problem, seen from two angles. “Ischemic” describes the damage: areas of brain tissue that didn’t get enough blood flow. “Microangiopathy,” known in the US as cerebral small vessel disease, names the cause: the tiny blood vessels that should be supplying those areas.

MRI slice (FLAIR sequence) of my brain in 2022. The arrow points to one of the white matter hyperintensities. The other lesions appear on different slices.

What Exactly Is It?

Cerebral small vessel disease (doctors also call it cerebral microangiopathy) affects the tiny arteries that supply blood to the deep parts of the brain. Their walls thicken and stiffen, the space for blood flow narrows, and the barrier that protects the brain becomes leaky. Plasma seeps into the surrounding tissue, causing swelling and inflammation, while the brain cells get less oxygen. On an MRI, these areas show up as small white spots called white matter hyperintensities. Over time, they’re linked to a higher risk of cognitive decline, balance problems, and stroke.

Where Do These Lesions Come From?

The main known risk factors are high blood pressure (even mildly elevated), vascular aging, poor blood sugar control and insulin resistance, chronic inflammation, high LDL cholesterol, elevated homocysteine, sleep apnea, smoking, and sometimes migraines.

In my case, most of these just don’t apply. I’ve never smoked. My LDL isn’t high, and neither is my homocysteine. No migraines, no sleep apnea, no high blood pressure, no blood sugar issues or insulin resistance.

That left one last, lesser-known factor: repeated exposure to high altitude. Studies of mountaineers who climbed extremely high peaks, and of pilots regularly exposed to low atmospheric pressure, show more white matter hyperintensities. Low oxygen and low pressure weaken the barrier that protects the brain, and repeated exposure seems to matter most. And in less than ten years, I climbed 45 peaks above 13,000 feet (4,000 meters). Low-grade inflammation and altitude: those are most likely the two factors behind my case.

A neurology professor told me: “Ma’am, I’m a professor of neurology. I know this subject well. There’s nothing to be done.”

I haven’t told you about this until now. First, because I didn’t want to worry anyone. Second, because I wanted to see whether my efforts would pay off.

August 2025: Three Years Later (MRI done as part of my yearly longevity evaluation at the YEARS CLINIC in Berlin)

The number of lesions had dropped to 11. Not bad for a condition considered irreversible. But skeptics might say: “That’s just a reading error. Let’s see if the trend holds.”

May 2026: Just Nine Months After the 2025 MRI (MRI done as part of my yearly longevity evaluation at the YEARS CLINIC in Berlin)

I was down to 9.

The Meeting Last Week

Last week, I met with Dr. Jordan from the Regenesis HQ in Los Angeles, who looks 15 years younger than his chronological age!

He reviewed my last two MRIs in detail. He spent more than an hour on them and took the time to walk me through everything. He was surprised and genuinely congratulated me. Then came the question: “So what did you do?”

And here’s the kicker: this protocol also had an impact on a second condition, which I’ll cover in an upcoming article. Again, a dramatic improvement.

Warning: This is a LONG piece with a ton of info…take your time reading it. Sit down….drink some water….breathe…and read :)

Lung function is one of the biomarkers almost nobody in the longevity space tracks.

We obsess over HRV, glucose, telomeres, epigenetic age.

I had a full pulmonary function work-up done in Berlin in August 2025 at the YEARS CLINIC: whole-body plethysmography, spirometry, diffusing capacity, respiratory muscle function, FeNO for airway inflammation, the whole battery.

I had no problem and no symptoms.

Nothing on that panel would have raised a flag with a pulmonologist, and I wasn’t chasing a diagnosis.

But a handful of markers, specifically airway resistance, gas transfer efficiency, and respiratory muscle strength, weren’t sitting where I wanted them: below the reference range instead of comfortably inside it.

Nothing was broken.

That’s exactly the point. I didn’t wait for something to break, or for a symptom to show up, before I acted.
I decided to make my lungs a dedicated 12-month focus anyway, because this is what biohacking actually is: acting on the earliest, quietest signal of a potential future problem, years before it would ever surface as a symptom, instead of waiting for a diagnosis to force your hand.

Again, I had no lung disease, no symptoms and nothing a pulmonologist would have considered alarming.

I focused on four specific interventions, including one unusual daily practice from a country most of us totally ignore when it comes to longevity. I believe this particular intervention played a major role in my biggest improvement.

Here is exactly what I did, what each test revealed and what the science actually supports.

Every year, Prescrire, a French medical journal funded exclusively by its subscribers, without a single cent from the pharmaceutical industry, publishes its blacklist of drugs it considers to have an unfavorable risk-to-benefit ratio.

For 2026, 108 drugs made this blacklist, the 14th year in a row.

If you're American and have never heard of Prescrire, that's kind of the point.

There's no real equivalent inside the US government: the FDA's drug review program is partly funded by the industry it regulates, through what are called user fees. The closest thing we have is Public Citizen's Worst Pills, Best Pills, an independent, donor-funded watchdog doing similar work.

One important note before we start: in drug safety science, not every risk comes with a clean, single number attached.

Some drugs have been studied in massive cohort studies with precise relative risks. Others only have scattered “reported cases,” with no known denominator, which doesn’t mean the risk is low, only that it hasn’t been publicly quantified yet. I’ll flag this every time rather than inventing a percentage that doesn’t exist.

But, let me tell you…..fair warning, the numbers are scary.

One very commonly prescribed anti-inflammatory is linked to

Another extremely common drug increases bone fractures by 200%.

Yet another, prescribed very casually for digestive issues like nausea, is linked to an estimated 200 sudden deaths a year in France alone.

You probably don’t know what’s coming in this list and believe me, you will be shocked!

Summer hits different when you’re in perimenopause or menopause, and not in the fun way. One minute you’re fine, the next you’re drenched, your heart is racing, and everyone around you is raving about the “beautiful weather.” If it feels like your own body declares war on you every single summer, you are not imagining it.

Now… can we do something to reduce the problem to a tiny little bothering thing? Yes! There are 6 specific things that actually work: not more breathing exercises, not another “cooling fabric” gimmick, but physiology-backed fixes you can start using today.

Over the decades, I consulted some of the most respected experts in the world—from renowned heads of gastroenterology departments at major institutions to lesser-known researchers whose work I deeply admired.

Not one of them was able to heal me.

I tried virtually everything: antibiotics, elemental diets, herbal protocols, prescription medications, fasting, non-fasting approaches, carnivore diets, high-fiber diets, probiotics, prebiotics, and countless other interventions.

Nothing worked for more than a few days.

Then, using what I had learned through years of study, experimentation, and continuous education, I designed a protocol for myself.

Today, I have been symptom-free for more than 12 weeks.

Even more surprising: I can now eat foods that used to trigger symptoms almost immediately—and experience none.

This is still an N=1 experiment, and I remain cautious. My next goal is to continue documenting the results over time, refine the protocol, and eventually test it in a larger group.

But after half a century of frustration, I can honestly say that I am amazed by the results.

Valérie Orsoni is a biohacker, author of 56 books, and founder of biohacker.fr. She has been tracking her biology through N=1 self-experimentation protocols since 1998. She is currently enrolled in Stanford Medicine’s longevity research certification program.

I’m writing to you from Paris. It’s 4 p.m. I pushed back every upcoming article to share this one urgently.

My hotel window looks out over a boulevard where the asphalt shimmers. The thermometer reads 39°C (102°F). Tonight it will stay at 25°C (77°F) minimum — which means my body won’t be able to drop below 37.5°C before 3 a.m., and my deep sleep will be nearly nonexistent.

Most people think they’ve handled the heat wave because they drank two liters of water and avoided running at noon. They’re wrong — and it’s not their fault. The official recommendations stop right where the biology keeps going. What I’m going to describe in this article are the mechanisms that extreme heat triggers deep inside you — in your mitochondria, your epigenome, your microbiome, your cardiovascular system, your blood sugar, and your HRV. Silent mechanisms. Mechanisms that age you.

And above all, I’m giving you a concrete plan to keep this heat wave from turning into silent accelerated aging — because extreme heat doesn’t just make you uncomfortable: it changes the expression of your genes.

Share

1. Heat accelerates your biological age — this is no longer a theory

In 2025, a study published in Science Advances analyzed the impact of extreme heat on the biological age of older adults using an epigenetic clock — a tool that measures the true age of your cells via DNA methylation. The results are unequivocal: exposure to extreme temperatures produces deep, lasting alterations in that methylation, particularly in genes tied to inflammation, metabolism, immune function, and cellular repair.

What’s even more troubling: these changes persist after the heat wave. Your body “memorizes” the thermal stress in a way that can turn out to be counterproductive for future biological challenges. A study from the Harvard T.H. Chan School of Public Health, covering more than 900 adults, showed that people exposed to high temperatures over several months had blood cells that appeared biologically older than their chronological age.

To put things in perspective: an accelerated biological age is an early predictor of cancer, dementia, and diabetes. A heat wave isn’t just uncomfortable — it changes the expression of your genes.

Share

2. Your mitochondria overheating — the engine that burns out

Extreme heat is a direct attack on the power plant of every cell in your body. At the cellular level, it induces massive oxidative stress, mitochondrial dysfunction, protein misfolding, and endoplasmic reticulum stress. The result: an overproduction of free radicals (the infamous ROS — reactive oxygen species) and a collapse in cellular energy production.

These imbalances don’t stay confined to the cell. They activate major inflammatory pathways — notably NF-κB and the NLRP3 inflammasome — and can trigger programmed cell death (apoptosis and pyroptosis). In parallel, vascular endothelial function is compromised: nitric oxide (NO) availability drops, vascular oxidative stress rises, and thrombosis risk climbs.

Bottom line: during a heat wave, every cell in your body is in survival mode, not performance or repair mode. It’s the exact opposite of what you’re trying to optimize as a biohacker.

3. Your gut is on fire — and nobody’s talking about it

Heat weakens the intestinal barrier. Animal studies have shown that thermal stress significantly changes the composition of the microbiome: the genera Lactobacillus and Bacteroides — the allies of your metabolic and immune health — decrease, while pro-inflammatory strains like Clostridium increase.

But that’s not all. When the intestinal barrier weakens, lipopolysaccharides (LPS) — fragments of bacterial cell walls — pass into the bloodstream. This is what’s called endotoxemia. And that endotoxemia triggers low-grade systemic inflammation: unexplained fatigue, brain fog, heightened pain sensitivity, hormonal disruption. The kind of silent inflammation that, accumulated over years, builds the terrain for chronic disease.

Share

The combination of heat wave + prolonged fasting + dehydration is particularly aggressive for the microbiome. If you practice intermittent fasting like I do (16:8), be careful to maintain robust electrolyte hydration during your fasting window, and don’t extend your restriction window during heat peaks. In fact, during a heat wave, my body naturally refuses to fast, and I start eating around 10 a.m. I listen to it.

4. The heart, the kidneys, the vessels — three organs under maximum pressure

When the temperature rises, your cardiovascular system triggers an emergency protocol: it redirects blood toward the skin to release heat by convection, which forces the heart to speed up. This is no small thing.

The kidneys are on the front line: they struggle to conserve water, which creates chronic renal stress during long heat waves. Epidemiological studies link intense heat episodes to spikes in kidney failure. And the blood itself becomes concentrated: hematocrit rises, viscosity increases, thrombotic risk is real — especially if dehydration is poorly compensated.

What many people don’t realize: dehydration isn’t just a question of water volume. When you sweat, you lose sodium, potassium, magnesium, and calcium — electrolytes essential to nerve conduction, muscle contraction, and heart-rhythm regulation. Drinking plain water without remineralizing means diluting even further what’s left.

5. Your blood sugar goes haywire — even if you’re not diabetic

Here’s something my Stelo CGM (Dexcom) lets me observe directly: high-heat days generate glycemic instability that most people never detect because they don’t measure.

Two mechanisms clash and create a dangerous oscillation: on one side, thermal stress stimulates the production of cortisol and adrenaline — hormones that raise blood sugar. On the other, heat dilates the blood vessels and speeds up glucose absorption, which can cause reactive hypoglycemia. The result: spikes and crashes that exhaust the pancreas, promote inflammation, and degrade metabolic flexibility.

If you follow a ketogenic or low-carb protocol like I do, you’re partially protected: your glycemic regulation is more stable at baseline, and you produce ketone bodies that supply backup fuel to the brain in case of metabolic stress. But even in ketosis, monitoring stays useful. A heat wave is a test of your metabolic flexibility under real-world conditions.

6. Your sleep sabotages your HRV — and therefore your longevity

This is the vicious cycle of the nighttime heat wave. To enter deep sleep, your body has to lower its core temperature by about 1°C. When it’s 30°C in your bedroom, that process is blocked or severely slowed. No thermal descent = no deep sleep = no recovery.

Share

The direct consequence: nighttime cortisol stays elevated, melatonin is reduced, and you wake up with a collapsed HRV. My Oura Ring and my WHOOP show it to me unambiguously: after every heat-wave night, my heart rate variability plunges by 15 to 25 points. And a chronically low HRV is a marker of accelerated aging, failing autonomic regulation, and systemic inflammation.

Sleep is when your body activates its cellular repair processes, its clearance of brain waste (the glymphatic system), its hormonal regulation. One night of bad sleep at 39°C does more biological damage than you’d imagine.

Heat-wave night protocol: bedroom below 22°C if possible (fan + lightly dampened sheets if you have no A/C), glycine 5g before bed to ease thermoregulation, magnesium bisglycinate for the parasympathetic nervous system, and if available, an extremity-cooling protocol (cold feet and hands help the body regulate its core temperature) — ice baths for the feet and hands, for example.

I add a Pulsetto session to support my HRV every day (code ORSONI for 10% off).

7. The epigenome that “memorizes” the heat wave

This is perhaps the most counterintuitive point — and the most important for anyone who thinks in terms of longevity.

Thermal stress doesn’t end when the heat wave ends. The heat-induced alterations to DNA methylation can persist long after temperatures return to normal. In the biology of aging, this is called “maladaptive epigenetic memory”: where short-duration stress builds resilience, chronic or extreme exposure creates a lasting biological imprint that the body struggles to erase.

This is the fundamental difference between controlled hormesis — like brief sauna exposure, at 80°C for 15–20 minutes in a prepared context — and heat that is endured, constant, uncompensated, at 40°C for days. The first makes you more robust. The second silently accelerates your biological clock.

That’s why intervention isn’t optional. A heat wave isn’t a parenthesis to “endure.” It’s an active biological stressor that leaves traces.

8. My biohacker protocol during a heat wave

Here’s what I put in place concretely, not theoretically:

Active hydration — not just water. Water + electrolytes (sodium, potassium, magnesium) every 90 minutes. I target 35–40 ml/kg/day during high heat, with special attention to sweat losses. I add hydrogen water (AxiomH2) in the morning on an empty stomach and mid-afternoon to counter the peak of thermal oxidative stress.

Real-time biological monitoring. My Stelo CGM lets me observe heat’s real impact on my blood sugar, hour by hour. My Oura Ring and my WHOOP give me my HRV, my basal temperature, and my sleep quality. This data doesn’t lie — and it tells me when my body is in recovery vs. in a stressed state.

Anti-heat-wave supplement stack:

• Creatine (10g/day, 5g of it for brain function): neuroprotective in situations of thermal stress, also supports muscular thermoregulation

  

• CoQ10 (400mg, ubiquinol form): direct mitochondrial support, particularly important when the mitochondria are under oxidative stress

• Resveratrol (600mg): sirtuin activation in the face of thermal stress, systemic antioxidant

  

• Magnesium bisglycinate (400mg in the evening): nervous-system relaxation, sleep preparation

• Liposomal vitamin C (2g): antioxidant cofactor, vascular support

Training windows. Zero intense activity between 11 a.m. and 6 p.m. My strength or high-intensity cardio sessions get moved to 7 a.m. or after 7 p.m. Heat adds a thermal stress on top of the metabolic stress of exertion — the combination massively increases allostatic load. I keep gym sessions if the gym is air-conditioned.

Sleep: an active battle. The coolest bedroom possible. Glycine 5g + magnesium before bed. Reduced light exposure starting at 8 p.m. so as not to disturb melatonin further.

If your HRV is in free fall several mornings in a row, that’s a signal: reduce the intensity of your workouts, increase protein (especially the repair amino acids), and prioritize the restorative over the performance.

Share

For peptide users: BPC-157 and TB-500 are especially relevant during a heat wave for their role in cellular repair and the modulation of systemic inflammation. If you use peptides, this is a period where protocol continuity takes on its full meaning. I get mine from two very clean US suppliers (available on valerieorsoni.com).

The heat wave as a test of your biology

Biohackers have an advantage that 99% of people don’t have: they measure. They observe. They adapt.

This heat wave isn’t just a weather constraint to endure.

It’s a real, documented biological stressor that temporarily — and, if you don’t respond, lastingly — changes your epigenome, your microbiome, your mitochondria, and your cardiovascular system.

The good news: the tools exist. The knowledge exists. And you, reading valbiohacker.com, have access to both.

Hydrate intelligently. Measure what’s happening in your body. Protect your sleep like a precious asset. And remember that every heat-wave day where you actively intervene is a day you get ahead of the aging that others are accumulating without even knowing it.

Forza!

Let’s keep going! Forza!

Ticks and red meat allergy? You’ve probably heard about it — and yet the epidemic is gaining ground and accelerating.

There’s no obvious link between the two — except that there is one, and it has a name: alpha-gal syndrome (AGS), also called “red meat allergy” or “tick bite meat allergy.” It’s one of the strangest food allergies in existence, and it is literally exploding right now.

In this complete deep-dive I’ll walk you through what’s happening around the world (the whole planet is affected), how to drastically reduce your risk, why people are blaming Bill Gates for this epidemic, and — above all — the promising avenues for getting out of it.

What Is It, Exactly?

Heavy legs — that sensation of fatigue, pressure, sometimes swelling or a dull ache in the lower limbs — is not simply a matter of discomfort.

It is the signal of a venous and lymphatic system under strain.

Physiologically, we are talking about chronic venous insufficiency (CVI) at varying degrees of severity.

Over time: varicose veins, edema, hyperpigmentation, and in severe cases, venous ulcers.

Venous stasis also creates fertile ground for the activation of NF-κB and the NLRP3 pathway — those who have been following me for a while will recognize these players in chronic low-grade inflammation.

Heavy legs are therefore not an isolated condition: they are part of the broader picture of systemic inflammation.

Let’s move on to my plan for addressing this highly disruptive phenomenon.

This is not a typical article. It’s the story of my father — his health trajectory, the verdict he received, and how he beat it. To the best of our knowledge, he may be the first documented case of severe emphysema reversed to this degree.

He no longer needs a CPAP machine to sleep. He no longer requires supplemental oxygen at night. His oxygen saturation holds at 96–97% without any assistance.

He is 85 years old.

I’m telling this story — his treatments, including everything outside the conventional system — with his full consent. Not to give you medical advice. I’m not a doctor. But because thousands of people receive the same sentence every year, walk home, and give up. I couldn’t stay silent.

Headlines are piling up, notifications are blowing up, and the COVID-19 comparisons are flying everywhere. Should we panic? Let’s take a clear-eyed look at a virus that’s been around a lot longer than most people realize.

Since the MV Hondius cruise ship incident in May 2026, the word “hantavirus” has been on everyone’s lips. But should we actually be worried?

As always, the answer lives in the data — not in the fear. Here’s a comprehensive breakdown of a virus that has existed far longer than you might think.

And at the end, I’ll share my personal preventive protocol rooted in science — and frankly, I can’t understand why nobody is talking about this approach, even though it’s approved by regulatory bodies in many parts of the world… including Europe and the USA.

I keep repeating my subtitle because it’s IMPORTANT and ignored!

Here’s what nobody tells you first. GLP-1 — glucagon-like peptide-1 — is not a pharmaceutical discovery. It’s a hormone your body produces on its own, naturally, and has been doing so forever.

It’s secreted by the L-cells of your small intestine at every meal. It regulates your blood sugar, sends a satiety signal to your brain, and slows digestion to prevent glucose spikes.

It does exactly what Ozempic and Wegovy claim to do.

The difference? Your endogenous GLP-1 is degraded within minutes by an enzyme called DPP-4. The drugs have been chemically modified to resist that degradation — maintaining pharmacological levels far beyond what your biology naturally produces.

Chronic stress elevates cortisol and inhibits GLP-1 secretion. Excess sugar and ultra-processed foods deplete the microbiome that stimulates its production. Sleep deprivation disrupts the circadian rhythm of this hormone. Sedentary behavior reduces receptor sensitivity.

Modernity breaks the machine, and the pharmaceutical industry sells the spare part.

The global GLP-1 market was valued at $62.83 billion in 2025. It’s projected to reach $180 billion by 2035. Around 10 million Americans were on GLP-1s in 2025 — a number expected to hit 25 million by 2030. This is one of the fastest-growing pharmaceutical markets in history.

This is not a moral judgment — it’s context that helps explain why emerging side effects aren’t making headlines the way they should.

In this article, we’ll do three things.

First, show you how to push your body to naturally rebuild its GLP-1 production — yes, it’s possible, and the science is solid.
Second, document the risks being hidden from you, some of them very serious and potentially irreversible.
Third, share pathways emerging from the literature to wean off GLP-1s — this is information from scientific literature, not medical advice: any decision to modify or stop a treatment must be made under medical supervision.

Let’s go.

Why? Because I want to apply this to myself. I have no interest in writing about something I am not willing to do.

And what I have found goes far beyond anything mainstream medicine is currently offering — and much of it isn’t even happening in the United States.

We are living through a quiet revolution in joint medicine.

Cartilage — long declared the tissue that “cannot heal itself” — is being coaxed back to life through combinations of biological agents that work synergistically at the cellular level.

The three-pronged protocol that has captured my attention most is…

I was born with juvenile arthritis.

A few years ago, I was told (by a doctor who did not know I was born with it) what millions of people hear every year: “You have osteoarthritis. It’s degenerative. Nothing can be done except manage the pain.”

Today, I have none.

Zero symptoms.
Zero pain.
Genuinely.
It still blows my mind even though I live it every day.
Zero cracking or popping when I bend my fingers like before.
And joints that handle high-altitude climbs, daily fitness sessions, and a full-throttle life.

So before you accept the verdict of “irreversible” — read this.

It’s rarely discussed—sometimes never mentioned—and yet urinary leakage affects more than one in three women after 40, and up to 50% of women after menopause.

In men, prevalence increases after prostate surgery.

This is not an inevitable consequence of aging.

It’s a biological signal.

And like any signal, it can be understood, corrected, and optimized.

In this guide, we will decode the physiological mechanisms behind urinary incontinence, then apply a multi-layer biohacking approach: functional exercises, targeted nutrition, evidence-based supplements, and advanced therapies for those who want to go further.

With this program, YOU CAN PUT AN END TO THESE ANNOYING LEAKS!

I hear about it constantly.

Some friends swear it cured “incurable” conditions. Others dismiss it entirely: “Just a useless grandma’s remedy.” Some even warn about serious allergic risks.

So — who should we believe?

I decided to investigate. Deeply. Scientific studies, meta-analyses, biochemical composition, dosing protocols… and personal experimentation on my own body (N=1 — we work with what we have).

What I discovered surprised me. Between exaggerated marketing claims and systematic skepticism lies a fascinating scientific reality. And some truly striking results.

Welcome inside the hive. Full breakdown.

You wake up systematically between 3am and 5am. Eyes wide open. Brain running at full speed. Impossible to fall back asleep before 6am... right when your alarm goes off.

Welcome to the very exclusive “3am crew” club.

Contrary to what pseudo-experts in Chinese medicine say (”It’s liver detox time”), there are precise physiological explanations for these nocturnal awakenings. And yes, you’re right: nocturnal hypoglycemia and cortisol spikes are the two main culprits.

But there are others. Many others.

I’ve dug into the scientific literature and tested several protocols on myself (and with my coaching clients). Here’s what I discovered.

They are a very common, ancient, multifactorial issue — and above all, biohackable.

In this piece, we go back to the origin of the word, the first medical descriptions, the real causes, the controversial role of fiber, the genetic question — and I share my best hacks to prevent or improve this condition… even if you don’t believe you have any “predisposition.”

We’ll also explore why carnivorous humans (who consume no fiber) often don’t have hemorrhoids at all.

Shocking — but true, and very easy to explain.

In modern medicine, we rarely ask that question. We celebrate innovation and breakthroughs, yet we often blur a critical distinction: ending a disease versus managing it indefinitely.

A cure ends the story.

Most drugs simply make it livable.

True one-time cures do exist. In recent years, gene therapies such as Zolgensma (for spinal muscular atrophy) and Luxturna (for inherited retinal dystrophy) have demonstrated that correcting the root genetic defect can dramatically alter the course of disease — often with a single intervention. These therapies come with staggering price tags, roughly $2.1 million for Zolgensma and $850,000 for Luxturna, but biologically, they do something rare: they remove the need for lifelong medication.

(FDA approvals: 2017–2019; peer-reviewed follow-up studies show sustained benefit in many patients.)

Contrast this with the dominant pharmaceutical model: lifelong treatment.

Examples are everywhere:

• Type 2 diabetes: metformin, GLP-1 agonists, insulin — often escalated, rarely stopped

• Hypertension: daily antihypertensives taken for decades

• Hypercholesterolemia: statins prescribed indefinitely

• Autoimmune diseases: biologics and immunosuppressants requiring ongoing injections or infusions

• Depression and anxiety: SSRIs and related medications often used long term

• Osteoporosis: antiresorptive drugs taken for years, sometimes for life

These medications can be life-saving and absolutely necessary — but they are management tools, not cures. Once stopped, symptoms or disease activity often return.

Even in infectious disease, where medicine has historically excelled, the distinction matters. Hepatitis C is one of the rare modern examples of a true pharmaceutical cure: short-term antiviral regimens can eliminate the virus entirely, with no further treatment required. This remains the exception, not the rule.

Why are cures so rare?

Biology is one reason. One-shot cures work best when a disease has a single, identifiable cause, such as a missing gene. Most chronic diseases are multifactorial, emerging from a complex interaction between genetics, environment, metabolism, inflammation, and cumulative exposure. There is no single switch to flip.

Economics also play a role. A therapy that works once must absorb decades of research, failed trials, and manufacturing risk into a single price. A drug taken daily spreads that cost over years — and sustains an entire healthcare system built around long-term use.

This is not a moral failure of medicine. It is a structural reality.

My Take: Reduce the Load, Don’t Just Add More

From a biohacking perspective, this distinction is essential. While waiting for one-shot cures for complex chronic diseases, the most powerful lever we have today is load reduction.

Lowering inflammatory burden, reducing toxic exposure, improving metabolic flexibility, supporting mitochondrial health, and restoring circadian and hormonal balance do not “cure” disease in the pharmaceutical sense — but they often reduce the need for escalating medication and slow biological aging itself.

In other words, if medicine excels at managing disease, biohacking aims to change the terrain in which disease develops.

As advanced therapies evolve, the future of health will likely live in the middle: targeted medical interventions when necessary, combined with aggressive reduction of the biological noise that keeps the body trapped in chronic dysfunction.

Because in the end, the most expensive medicine is not always the one with the highest upfront price — it is the one you need to take for the rest of your life.

Holidays, digestion, and biological reality

The holidays are here. And with them… repeated XXL meals.

We no longer eat out of hunger, but out of indulgence, tradition, social automatism. Rarely a cucumber consommé, let’s be honest — but rather Yule log cakes, cheese platters, meats in sauce, gratins, chocolates, and candied chestnuts.

And as if that weren’t enough, sugar attacks us from all sides: gifts from friends, colleagues, neighbors, clients, family…

The result: we’re drowning in chocolate and sweets.

👉 Hello blood sugar, by the way.

When the stomach says stop (but too late)

These meals are often so rich that the stomach becomes physically distended.

An essential reminder: when empty, the stomach is about the size… of your clenched fist.

So yes, when we eat well beyond this natural capacity, the discomfort is real and strictly physiological.

And on top of that, we have:

• fermentation of certain foods,

• the acidity of others,

• digestive slowness linked to fats and poorly broken-down proteins.

👉 The result?
