The Gut Myths I Let Go By week thirty-two, he expected answers. A perfected protocol. The blueprint, the map, the control switch. But the further he went, the clearer it became: some of the most important discoveries came not from what worked – but from what he had to let go. For years, he carried...
All that matters He wasn’t there to win. Not even to prove anything. He was there to complete, not to compete. The first half of the run had felt almost unreal – steady, light, and oddly joyful. But the second half? That was where the truth lived. That’s where everything he thought he had mastered...
I Am a Different Man Now – Running 71 kms on UltraBiome He never expected clarity to arrive mid-stride – yet that’s exactly how it happened. Somewhere between the silence of dawn and the rhythm of his feet on gravel, a thought emerged: “I’m not the same man who started this journey.” Ten days before...
What I’ll Keep Doing Forever In his thirties, he chased performance. In his forties, he chased recovery. But as fifty approached, he realized the race itself had changed. It was no longer about squeezing more out of his body. It was about aligning with the rhythms of nature, the quiet signals of microbes, and the...
Rebooting My Aging Immune System For most of his life, he thought of immunity as a defense line – soldiers waiting to attack viruses, pathogens, or anything foreign. But as he approached fifty, he noticed something quieter but more unsettling. He wasn’t falling ill often, yet when he did, recovery dragged. A scratch healed slower....
Mood, Memory, and Microbes Before this journey, he thought that mental health was only about neurotransmitters – serotonin, dopamine, GABA – a chemical orchestra conducted by the brain. But as fatigue, brain fog, and low resilience crept into his own life, he began to see the picture differently. His microbes weren’t background noise. They were...
Cleaning House with My Gut’s Help For years, he rolled his eyes at the word detox. It sounded like a marketing trick – celebrity juice cleanses, vague promises of “flushing out toxins.” As a clinician, he dismissed it as pseudoscience. But when his own system began to stall – sluggish energy, uneven digestion, foggy mood...
The Elite Forces of My Microbiota In the past, he had dismissed probiotics as just capsules of “friendly bacteria” with labels more ambitious than their actual effects. Most strains were fragile, rarely colonized, and often passed through like tourists. But then he discovered the newer class: spore-formers, butyrate-producers, pasteurized metabolic trainers, and engineered consortia. These...
My Microbial Inner Circle Explaining the microbiota was always a balancing act. People wanted clear roles: good vs. bad, heroes vs. villains. But the truth he came to see, after years of clinics, experiments, and even gut rewires, was far more intricate. The gut isn’t a battlefield. It’s a living web.A network of nodes and...
The Miracle Molecules Back in the old days during university, he had thought of digestion in simple terms – calories in, nutrients absorbed, leftovers discarded. But the “leftovers” weren’t waste at all. The indigestible fibers that humans can’t break down became the raw material for something else entirely: short-chain fatty acids (SCFAs). Tiny molecules, made...
Cravings Are Clues For decades, he treated cravings like enemies. Evening sugar, stress-snacking on chips, the strange urge for bread even when full – he blamed willpower, maybe metabolism, maybe old habits. But the more he learned, the more he saw a different story: cravings weren’t failures. They were signals. The science pointed in that...
Putting Out the Fire Inside For years, he thought he was eating enough fiber. A salad here, a banana there, the occasional bowl of oatmeal. It felt balanced. But when he began looking more closely at the science, he realized: fiber wasn’t a number on a label. It was a language. And most of his...
I Sequenced My Gut—Here’s What I Found It wasn’t just curiosity anymore – it was accountability. After months of restructuring his habits, feeding his microbes, and testing the limits of rhythm and food, he wanted to see if the inside reflected the effort. Who exactly was living in him now? He had always warned patients...
How Sweet It Isn’t He had always been suspicious of “sweet without calories.” It sounded like cheating nature. And the more he dug into the science, the more he realized that his instinct wasn’t entirely wrong – but neither was it completely right. Artificial sweeteners weren’t one story. They were many. Saccharin, sucralose, aspartame, stevia,...
My Cells Needed a Microbial Upgrade He had felt it for years – that creeping fatigue that no coffee could fix. His labs looked fine, his diet clean. But deep inside, he knew something was off. Not just a gut issue. Not just aging. Something cellular. That’s when he began connecting the dots: the gut...
The Hidden Toxins Around Me He once believed health was mostly about food, fitness, and rest. But the deeper he went into microbiota science, the more he realized another invisible layer was at play: the exposome—the total sum of environmental exposures we encounter daily. Plastics, pollutants, fragrances, cleaning chemicals, heavy metals, even the air he...
The Great Fermentation Experiment He’d eaten sauerkraut before. Occasionally bought kombucha. Maybe spread a little miso into soup. But until now, fermentation had been just flavor. Not medicine. Not a mission. That was about to change. The more he studied the microbiota, the more one truth kept surfacing: populations with higher microbial diversity often include...
Vice and Virtue in the Gut World For years, he thought small indulgences were harmless. A glass of wine, a strong espresso, the occasional painkiller. Not excess, not abuse – just comfort. But as his journey deepened, he realized something subtle: even the “little things” were messages to the microbiota. Alcohol, for instance, carried more...
The Testosterone-Gut Tango He never obsessed over testosterone. But as he neared 50, he noticed things changing. Recovery slowed. Motivation dipped. Muscle didn’t build like it used to. And it wasn’t just the gym – it was life. He wondered if his hormones were whispering something his microbes already knew. Then he found the research:...
You Are What Grows On You For most of his life, he treated skin as an afterthought – something to wash, shave, moisturize when dry. A functional cover, not an active organ. But that changed when he dove deeper into microbiome research. The science was undeniable: the skin wasn’t just a barrier. It was a...
Stress, Cortisol & Gut-Brain Axis
A legbelső szerotonin védelem Az egyetemen úgy gondolta, hogy az immunitás a vérben zajlik – T-sejtek, antitestek, gyulladás. De minél többet olvasott, annál világosabbá vált: az igazi frontvonal a nyálkahártya, különösen a bélben. És a titkos katona, aki ezt a határt őrzi? Egy molekula, amit úgy hívnak: szekretoros IgA. A bélfal plazmasejtjei által termelt szekretoros...
Strong Body, Resilient Gut He had always respected muscle. As a doctor and former thriatlonist, he’d seen firsthand how lean mass predicted everything from blood sugar stability to injury recovery. But now, as he moved closer to his 50th year, he saw it differently. Not just as armor – but as fertile ground for microbial...
I Fixed My Sleep, and My Gut Thanked Me At first, he thought his sleep issues were age-related. He’d wake up at 3 a.m., mind racing, heart slightly elevated. His Garmin watch showed fragmented deep sleep. He tried magnesium, meditation, white noise, blackout curtains. They helped – briefly. But nothing stuck. Then he looked inward....
Bugs in a Bottle: Friend or Hype? He stood in the supplement aisle of a well-stocked organic market, staring at a wall of promises. Probiotics for immunity. Probiotics for stress. Probiotics for weight loss. Probiotics for replacing hair. Dozens of bottles with billions of CFUs per capsule, many costing more than a nice dinner. And...
Feeding the Right Army He often joked that if the body were a castle, then the immune system was its army – and the gut microbiota was the black-ops unit that trained them. But like any army, it needed to be fed. And not with sugar, caffeine, and ultra-processed flour, but with what microbes actually...
The Clock That Heals It wasn’t hunger that woke him – it was rhythm. He began rising earlier. Not because of discipline or a new alarm, but because his body started syncing with something deeper. He had changed what he ate, but now it was time to change when he ate it. And it began...
My Gut Garden Begins to Bloom There was a time when he thought of nutrition purely in terms of macros. Just as he learned: protein to rebuild, carbs to fuel, fats to balance hormones. But now, after clearing out his pantry, his mindset had shifted. Food wasn’t fuel. It was fertilizer – for the invisible...
The Enemies in My Pantry For someone who had competed in triathlon races, he wasn’t expecting to lose a battle to a granola bar. But there it was – half-eaten on the kitchen counter, smug in its plastic wrapping, listing ingredients that barely sounded like food: glucose-fructose syrup, “natural flavor,” soy isolate, sunflower oil, emulsifiers,...
Would You Swallow That to Live Longer? He had done strange things before. Fasted for 3 days. Ran a 42K with nothing but water and salt on a 400m track. But then he was only 17. Participated in over a hundred fecal transplants. But this was different. This time, the recipient wasn’t sick. This time,...
The Invisible Organ – Meet My Microbiota If you asked him twenty-five years ago, just after university what the most underrated organ in the human body was, he would’ve said the fascia. The brain. No! Definitely the liver. Now? It’s not even close. It’s the microbiota – the dense, teeming ecosystem of microbes that lives...
The Beginning: A Gut Feeling They say knowledge is power. But at 49, sitting at the edge of a trail he once visited as a beginner runner, he wasn’t so sure anymore. He had spent most of his life and career looking for something meaningful that would help others – dozens of patients with mysterious...
Let’s run an ultramarathon Is it possible for a perfectly average middle-aged man to change his lifestyle and, in a short time, reach a level of physical performance he had never achieved before? Do we already have enough knowledge to shorten this journey? If experience has shown that a bacterial composition from runners is more...
