And what could change everything else.
You've tried diets, fitness, generic supplements. Nothing held for long. Not for lack of discipline — because no one had looked at the organ silently driving all of it: your gut microbiome.
Certified analysis at the Physioquanta laboratory
If you live with these symptoms...
Many women live with these signs for years without knowing they share a common thread: your gut microbiome is malfunctioning. Not dramatic. Not irreversible. But clearly out of balance.
Digestion
Energy & emotions
If you check more than 3 boxes, you don't have a willpower problem. You have a terrain problem. And terrain can be measured. Worked on. Rebalanced.
"When your microbiome is out of balance, YOU aren't the problem. What's driving your body has gone off track."
Understanding the topic
It's talked about everywhere without ever being properly explained. Here's what it is, what it does, and why its balance determines much more than your digestion.
Your gut microbiome is the collection of microorganisms — mostly bacteria — that live in your digestive tract, especially in your colon. It was first discussed in detail in the 2000s, and scientific research on the subject has exploded over the past 15 years.
100 trillion
bacteria live in your gut
1.5 to 2 kg
that's the total weight of your microbiome
+1,000 species
different bacterial species can coexist in you
To give you an idea: you have as many (and even more) bacteria in your gut as human cells in your entire body. These bacteria aren't invaders — they're essential to how you function.
Your microbiome isn't just there for digestion. It performs 4 vital functions that touch your digestion, your immunity, your mental health, and your weight regulation.
Digestion
Your microbiome breaks down what your body can't digest alone (complex fibers, certain carbs). It transforms all of that into absorbable nutrients and into compounds that nourish your gut wall.
When it malfunctions: bloating, fermentation, intolerances, distended belly.
Immunity
70% of your immune system is housed in your gut. The microbiome bacteria form a barrier that prevents pathogens from passing into the bloodstream, and that educates your defenses.
When it malfunctions: repeated infections, chronic inflammation, allergies, autoimmune terrain.
Mood & sleep
About 90% of serotonin (the well-being hormone) is produced in the gut — not the brain. Your microbiome also produces GABA, dopamine, and melatonin precursors. That's the gut–brain axis.
When it malfunctions: anxiety, sadness, rumination, fragmented sleep, irritability.
Weight & energy
Your microbiome directly influences how you store or burn energy: certain bacteria favor fat storage, others oxidation. It also regulates your hunger and satiety signals.
When it malfunctions: unexplained weight gain, cravings, chronic fatigue, insulin resistance.
DYSBIOSIS describes when your microbiome loses its diversity or when certain bacterial populations overtake others. It's not a disease in the classical sense — it's a terrain sliding toward imbalance.
Loss of bacterial diversity
fewer species = fewer functions performed
Imbalance in proportions
certain bacterial families become dominant at the expense of others, creating inflammation
Loss of gut barrier
the gut wall becomes permeable — that's "leaky gut"
The good news: dysbiosis can be MEASURED precisely in a laboratory. And it can be REPAIRED with a strategy adapted to your specific terrain. Not with generic probiotics from the pharmacy.
"You can't fix what you've never measured."
The link no one shows you
If you've gone through diet after diet without lasting results, it's not your metabolism, your willpower, or your age. It's a precise biological imbalance that no caloric restriction can compensate for. Here's how it concretely works.
Mechanism 1
Certain bacterial families (notably Firmicutes in excess) extract MORE calories from food than others. With them dominant, even a low-calorie diet can be enough to maintain your weight — or even raise it.
What you live
"I eat little, I lose nothing"
Mechanism 2
When certain pathogenic bacteria take over, they "demand" their preferred food: fast sugars and ultra-processed foods. They send signals to the brain via the vagus nerve and neurotransmitters.
What you live
"I'm not hungry, but I can't stop myself"
Mechanism 3
Chronic dysbiosis maintains low-grade inflammation throughout the body. This inflammation disrupts the hormones that regulate satiety (leptin) and insulin sensitivity. The result: your body runs in "survival" mode, storing instead of burning.
What you live
"I have belly fat that won't leave, even when I lose weight"
As long as you try to lose weight ON THE SURFACE — calories, exercise, fasting, restriction — without touching the underlying chemistry that drives your storage, your cravings, and your inflammation, your body will return to its imbalanced equilibrium.
That's the "rebound effect." Not a fatality. The logical consequence of trying to treat a terrain that was never measured.
"You don't have a calorie problem. You have an inner ecosystem problem."
Concrete action
The good news: a damaged microbiome can be restored. The less good news: you have to know precisely what damaged it in YOU — not in the average woman. Here are the major categories to know.
Repeated antibiotics
A course of antibiotics destroys up to 90% of bacterial diversity. Without proper support, the microbiome takes months — even years — to rebuild.
Ultra-processed foods
Emulsifiers, preservatives, hidden added sugars. These compounds change the gut environment and favor pro-inflammatory bacteria.
Prolonged stress directly modifies your microbiome composition through the HPA axis and the vagus nerve. Not a metaphor — a measurable biological mechanism.
Regular alcohol consumption
Alcohol attacks the gut wall and favors abnormal permeability (the leaky gut we discussed).
Poor in fibers and plants
Fibers are the main fuel for good bacteria. A diet poor in varied plant foods literally starves your beneficial microbiome.
Chronic or unfit sleep
Gut bacteria have their own circadian rhythm, intimately tied to yours. Degraded sleep cascades into microbiome imbalance.
Varied dietary fibers, adapted to your terrain
Legumes, vegetables, fruits, whole grains — plant diversity feeds bacterial diversity. It's the #1 lever for deep restoration.
Targeted & adapted fermented foods
Kefir, kombucha, kimchi, raw sauerkraut, homemade fermented yogurt. They bring useful live strains — provided they integrate with YOUR microbiome.
Real stress management (not cosmetic)
Hypnotherapy, meditation, sophrology, regular vagus nerve practice — not a yoga weekend once a year. The microbiome responds to chronic stress, not to occasional spikes.
Sleep aligned with your chronotype
Bed before midnight, exposure to natural morning light, light dinner 3 hours before bed. Your microbiome regulates at night.
Physical activity matched to your microbiome
Walking, cycling, swimming — not intensive sports that create oxidative stress. 30 minutes of daily movement is enough to enrich bacterial diversity.
TARGETED supplements, not generic ones
Probiotics, prebiotics, postbiotics — only effective if they match YOUR specific microbiome. Otherwise, it's roulette.
You can follow all of this advice diligently for 6 months without seeing change. Why? Because EVERY microbiome is unique. The fibers that nurture good bacteria in your neighbor may feed pathogens in you. The probiotic that calms her colitis may worsen yours.
That's why we start by MEASURING your specific microbiome before telling you what to do.
"Eating well is necessary. Eating well for YOU is what changes everything."
Our approach
We don't sell you a standard microbiome program. You wouldn't buy shoes without knowing your size — why would you do that with your gut health?
Physioquanta kit sent to your home. Simple, painless sample collection at home. You return the kit, the French Physioquanta laboratory runs the full analysis: bacterial diversity, balance of major families, inflammation markers, gut permeability.
Six weeks after the sample collection, we meet for a 60-min appointment. We read your report line by line. You leave with clear understanding — not an unreadable file you'll put in a drawer.
From your results, we build your full strategy along 3 dimensions:
Not a diet — a roadmap adapted to YOUR 3 dimensions.
Your strategy doesn't stay a theoretical roadmap. We support you to put it in place concretely, we adjust based on your feedback, tests, and the evolution of your microbiome. A reassessment is offered at 3 months, 6 months, or 1 year depending on your profile — option available in the Premium Microbiome Analysis and the Spark Program. New kit, new analysis. We compare, we adjust, we confirm what works, we simplify, we remove what no longer applies.
That's what we call the Premium Microbiome Analysis. A full cycle to understand your terrain, repair it, and learn to maintain it autonomously.
€350 · No program commitment · The kit, the analysis, the strategy
The Physioquanta kit is a recognized tool, used in France by professionals trained in human microbiomics.
The difference with us: we don't just hand you the results. We translate them, we build your strategy, and we support you in implementation.
"Measuring your terrain is to stop sailing blind."
Your questions
The questions we're asked most often — and the ones we asked ourselves when we discovered microbiomics.
The Physioquanta kit arrives at your home by mail, in a discreet package. It contains a sample collector, clear instructions, and a pre-paid envelope. You collect the sample at home in a few minutes. You put the kit in the envelope, you mail it. The lab receives, analyzes, and sends us the results within 6 weeks.
It's painless. No blood draw, no office visit, no fasting required. Just a stool sample to do at home.
And you're never alone with the sample collection: Peggy offers you a 15-minute appointment to guide you on the method, answer your questions, and clear up any doubts. No cold instruction sheet to decipher alone.
It depends on what your initial assessment reveals. For most women in our program:
But we are clear: this isn't a 21-day transformation program. Count at least 6 months to truly transform a microbiome in depth. It's foundational work that unfolds over time.
The Premium Microbiome Analysis isn't covered by French Social Security (microbiomics not yet integrated into the standard care path). Some complementary insurance plans partially cover hypnotherapy consultations, but it varies.
The full analysis price (kit + lab analysis + reading + strategy) is €350. Owned transparency: we don't bill long support when the analysis alone is enough.
Yes, and it's even recommended. Our approach isn't a substitute for medical follow-up — it's a complement. If you take chronic medication or are followed for an identified pathology, we work in coherence with your care path.
And conversely: our analyses can bring useful information to your primary care doctor or gastroenterologist, who can integrate them into their assessment.
No. And it's an important question. The women we support have real lives: family, work, constraints, pleasures. A strategy that requires you to eat 100% differently overnight doesn't hold — and we know it.
Our approach: we identify the 3 to 5 priority levers for YOUR specific microbiome, and we put them in place progressively. We move in small steps — that's our philosophy. It's neither a diet nor a monastic lifestyle. It's a surgical and lasting adaptation.
The microbiome changes throughout life, but it's especially from 35-40 years old that we observe a natural loss of bacterial diversity — accentuated by chronic stress, repeated antibiotics, evolving hormones (perimenopause notably).
That said, there's no minimum age. A 30-year-old woman coming out of multiple antibiotic courses or living through intense stress can derive immediate benefit from an analysis. And a 65-year-old woman can fully restore her microbiome with the right strategy.
Now that you know...
