12 tricks to beat the bloat and get rid of that muffin top for good - and why it matters in the long run
PRECISION HEALTH & LONGEVITY OPTIMISATION With Mirthe Eckl
What it is. Why it matters. What becomes possible.
You want to feel, function and perform at your best — not just now, but for decades to come. You are interested in health and longevity, but increasingly overwhelmed by the noise: cold plunges, peptides, supplements, biohacking trends, conflicting advice online.
But what is actually evidence-based? What is personalised? And what simply doesn’t matter for your unique biology?
Perhaps your annual check-ups come back as ‘normal’, yet subtle issues are starting to appear — blood pressure slowly creeping up, energy dips after meals, poor sleep or brain fog, declining resilience, aching joints. These symptoms are often dismissed as just part of getting older.
Many of these seemingly small issues are early signals that the body is under strain — long before disease develops. True health and longevity optimisation is not about extreme restriction or chasing the latest fad. It is about understanding your unique biology and choosing precise, personalised, science-backed interventions that improve how you feel now and protect how you function for decades to come.
All while still fully enjoying life. After all, longevity without quality of life is hardly longevity at all.
What Science Actually Says About Ageing & Health
While most people think of different health problems as separate issues, research over the past decade paints a different picture. Alzheimer’s, cardiovascular disease, cancer, metabolic decline — these are not isolated conditions with separate origins. Most chronic health issues share the same underlying factors, known as the 12 hallmarks of ageing.
These include chronic inflammation, faulty cellular communication via hormones and neurotransmitters, fraying of the genes (telomere attrition), problems with cellular energy production (mitochondrial dysfunction), and cells that linger and cause damage — known as senescent or ‘zombie’ cells, among others.
Rather than one pathway leading to one problem, these factors interconnect and contribute to all major health issues — now and down the line. Think of it like a cogwheel machinery. A little rust and sludge building up in one wheel has a knock-on effect across the entire system. Over years and decades, if left unchecked, the whole machinery grinds to a halt. That is when the full-blown diagnosis arrives.
The sludge causing your fatigue today is the same process — at an earlier stage — that drives serious disease decades later.
This is what makes early intervention so powerful. You are not waiting for a diagnosis. You are acting on the signals now.
Mainstream longevity medicine has caught onto the hallmarks of ageing — and often focuses on supporting individual pathways through targeted supplements, medications or interventions. Think anti-inflammatory drugs, NAD+ injections or metformin. These have a role to play and can be genuinely helpful when used appropriately.
Functional Medicine takes this one step further. It asks the question: Why. Why are these pathways blocked in the first place? Why is there rust and sludge? Where is the inflammation coming from?
And then works on addressing the root underlying triggers — not just supporting one hallmark or pathway, but clearing out what caused the problem to begin with.
Think of it like an oil change for your car. Not a patch. A full system clean.
Treating symptoms — however sophisticated the treatment — is fundamentally different from identifying and addressing what is driving them. The first requires ongoing management. The second creates the conditions for genuine, lasting change.
Why 'Normal' Is Not Good Enough
The reference ranges used by most labs are not based on an average of optimally healthy people. They are based on the general population — which includes people who are pre-diabetic, hypertensive, or already in early stages of metabolic decline.
So when a result comes back within the normal range, all it confirms is that you are not yet in an overt health crisis. It says nothing about whether your cells are functioning optimally.
This is the territory that Precision Health operates in. Not just the space between sick and healthy — the space between normal and optimal. It is where the most powerful and preventative work happens.
Who This Is For
This approach tends to attract two broad groups of people — and once you understand the cogwheel machinery of health, it becomes clear why, because the same underlying drivers connect them both.
Group 1 — Proactive & Prevention Those who feel broadly well but want to be precise and proactive. High performers who are not satisfied with ‘normal’ health. They want to understand their biology precisely, optimise cellular function, and build a health trajectory that keeps them performing at their best — now and in twenty years.
Group 2 — Root Cause Support Those with existing symptoms or conditions seeking root cause resolution. People who have been told ‘this is just how it is’ — that they will need to manage their condition indefinitely. Functional Medicine does not accept that conclusion without first asking whether the root cause has truly been identified and addressed.
The body is designed to heal, given the right conditions.
Whether the goal is prevention, optimisation, or support — the work is the same. Find the root. Address it systematically. Change the trajectory.
The Approach
The foundation of the work is a 360 approach — diving deep into the history of that person, then deciding on appropriate testing to identify the root of cellular decline, and building a personalised strategy that fits their unique biology, lifestyle, preferences and goals.
Testing includes standard blood panels placed into stricter optimal ranges, alongside specialist panels where needed: gut microbiome analysis, hidden infections, food intolerances and allergies (blood testing — not hair testing, which is not clinically validated), hormone panels including DUTCH dried urine testing, environmental toxins, predictive biomarkers, DNA health testing, and more.
Test, don’t guess. Finally taking the guesswork out of health and longevity optimisation.
About Mirthe
Mirthe Eckl helps high-performing individuals optimise their health and longevity through a precision, data-driven approach. She specialises in Functional Medicine, predictive biomarker testing and the identification of root causes — with a particular focus on chronic inflammation as a driver of hormonal imbalances and complex chronic health concerns.
Her work sits at the intersection of science and lifestyle medicine, working with entrepreneurs, CEOs, high-net-worth individuals and those committed to performing at their best, both in clinic in London and remotely.
Her approach is precise and data-driven, yet deeply personal — rooted in lived experience. After being diagnosed with Crohn’s disease at a young age, Mirthe spent years exploring both conventional and alternative approaches to health. While many offered temporary relief, it was through scientific research that she was able to address the root cause, leading to long-term remission. That experience shapes the way she works today: investigative, personalised, evidence-based and results-driven.
Alongside her practice, Mirthe speaks and educates on longevity, hormones, gut health and performance optimisation — bridging the gap between cutting-edge science and real-world application.
Her focus is to help people move from suboptimal to exceptional health — with clarity, precision and long-term results.
The First Step
If this resonates, the next step is a Discovery Consultation — a focused, no-pressure conversation about your health goals, Mirthe’s approach, and whether Functional Medicine is the right fit for you. No clinical deep dive at this stage. Just an honest discussion about what might be possible.
