FUME Is Building India’s First Root-Cause Metabolic Health Platform — And Challenging How the Country Thinks About Preventive Wellness

(MENAFN- Raidonnews) A 45-year-old operations head at a Pune logistics company went for his annual corporate health checkup. The standard panel — fasting glucose, lipid profile, TSH, liver and kidney function — came back clean. His doctor told him he was fine. Two years later, he was diagnosed with Type 2 diabetes. Three years after that, he was on blood pressure medication.
His reports had been “normal.” His body had not. The tests were simply not asking the right questions.

This is the gap that FUME — Fix Underlying Metabolic Errors, a Bengaluru-based metabolic health platform founded in 2020, was built to close. In a country where over 100 million people live with diabetes, 1 in 10 adults has a thyroid disorder, and nearly 1 in 5 women of reproductive age deals with PCOS, FUME argues that the problem is not a lack of medication or diet. The problem is that most health interventions begin without understanding what is actually going wrong inside the body.

"A standard corporate health checkup tests a handful of basic markers — glucose, cholesterol, TSH — and declares you healthy. We run 85+ metabolic blood markers, screen for 200+ genetic risk conditions, analyse the gut microbiome, and track real-time glucose response. The difference is not incremental. It is the difference between reading a car’s dashboard and actually opening the engine." — Jagannath Das, Co-Founder and Director, FUME

The Origins: Two Founders, Two Transformations, One Company

FUME’s founding story is not a business school case study. It is a health story.

Jagannath Das spent 17 years in corporate leadership roles at Samsung, Bosch, and Aptiv — building business strategy, managing operations, driving growth. By 38, he was also clinically obese. His annual health reports looked acceptable. His body was failing — chronic fatigue, stubborn visceral fat, declining energy, and a health trajectory pointing toward exactly the metabolic diseases that run in millions of Indian families.

Conventional healthcare had no answers beyond “eat less, move more.” Jagannath discovered functional medicine and root-cause diagnostics. Over the next few years, he underwent a complete metabolic transformation — reversing his health markers, losing significant weight, and rebuilding his energy and vitality from the ground up. The experience was transformative enough that he left his corporate career to make this approach accessible to others.

Dr. Uma Mittal, FUME’s Co-Founder and Chief Metabolic Health Officer, came to the same conclusion through a clinical lens. A metabolic health expert with international certifications from the Institute for Integrative Nutrition (IIN, New York), Precision Nutrition, and NASM, along with an Advanced Certificate in Functional Medicine & Clinical Nutrition, she brought deep clinical expertise in hormonal health, gut health, and root-cause diagnostics. But it was her own hormonal and metabolic challenges that made the philosophy personal. Conventional treatment managed her symptoms without resolving them. Through rigorous application of functional medicine principles and root-cause diagnostics, she reversed her own conditions and became committed to bringing this evidence-based approach to the thousands of women dealing with PCOS, thyroid dysfunction, and fertility challenges across India.

Together, the two founders lost 36 kg combined. More importantly, they reversed the metabolic dysfunction that standard medicine had been content to “manage.” FUME was born from a shared conviction: what worked for them could work for thousands of others — if built into a systematic, science-backed, scalable platform.

The FUME Bio-Intelligence System: 8 Pillars, 85+ Blood Markers, 200+ Genetic Conditions
At the core of FUME’s methodology sits the Bio-Intelligence System™ — a proprietary diagnostic framework that analyses 8 interconnected biological systems before any intervention is designed.
This is what separates FUME from the diet plans, gym programmes, and generic health coaching that dominate India’s wellness industry. While most programmes start with advice — what to eat, how to exercise — FUME starts with data. Where a standard health checkup checks a handful of surface-level markers, FUME’s framework spans 85+ metabolic blood markers, genetic and epigenetic screening across 200+ health conditions (covering cancer risk, cardiovascular, nutrition, drug response, autoimmune, mental wellness, diabetes, and more), gut microbiome profiling, comprehensive hormonal panels, continuous glucose monitoring, body composition analysis, and lifestyle stress assessment.

The 8 pillars of the Bio-Intelligence System cover:

Epigenetic & Genetic Intelligence — using one of the world’s most extensive wellness genetic tests, FUME screens for risk across 200+ health conditions spanning 21 categories — including nutrition, cardiovascular, cancer predisposition, drug response, autoimmune, mental wellness, diabetes, obesity, hormonal, and metabolic traits. This reveals how an individual’s genes influence nutrient processing, detoxification pathways, inflammation tendencies, and metabolic efficiency — and why the same food can be beneficial for one person and harmful for another. Genetic and epigenetic testing is conducted for all clients in FUME’s transformation programmes using a simple saliva-based DNA collection kit.

Gut Microbiome Analysis — assessing microbial diversity, gut-driven inflammation, and the microbiome’s influence on fat storage, hormone production, thyroid conversion, and immune function.

Deep Metabolic Blood Panel — testing markers that standard health checkups routinely miss, including HOMA-IR (the gold-standard measure of insulin resistance), fasting insulin, hs-CRP (systemic inflammation), triglyceride-to-HDL ratio, homocysteine, and comprehensive vitamin and mineral panels.

Hormonal Health Panel — comprehensive thyroid assessment (Free T3, Free T4, thyroid antibodies — not just TSH), adrenal function, reproductive hormones, and metabolic hormonal signalling.

Continuous Glucose Monitoring — real-time blood sugar response tracking that reveals hidden spikes, metabolic inflexibility, and food sensitivities that a single fasting glucose test cannot detect.

Body Composition & Visceral Fat Analysis — measuring fat distribution, muscle mass, and visceral fat levels rather than relying on body weight, which cannot distinguish between losing fat and losing muscle.

Lifestyle & Metabolic Stress Analysis — evaluating cortisol patterns, sleep quality, recovery capacity, and chronic stress triggers that silently drive insulin resistance and hormonal disruption.

Longevity & Biological Age — assessing cellular stress signals, biological age trajectory, and long-term metabolic resilience.

Not every client undergoes every assessment. FUME’s clinical team — which includes functional medicine doctors alongside internationally certified health coaches and specialists — determines which pillars are most relevant based on the individual’s symptoms, health history, and goals. But the framework ensures that no critical system is overlooked, and that interventions are designed based on biological data rather than generic assumptions.

"Most health programmes guess. We measure. That is not a marketing line. It is a fundamentally different starting point." — Jagannath Das, Co-Founder and Director, FUME

Who FUME Serves — And What They Have Typically Tried Before
FUME’s client base is not the casual health-curious consumer. The platform primarily serves professionals and entrepreneurs aged 35 to 65 — individuals who have typically spent years and significant money on diets, gym memberships, supplements, and specialist consultations without lasting results.

The conditions FUME most commonly works with include Type 2 diabetes and pre-diabetes, thyroid disorders (including Hashimoto’s), PCOS and hormonal imbalances in women, stubborn belly fat and weight loss resistance, infertility linked to metabolic and hormonal dysfunction, chronic fatigue, and gut health issues.

The company’s client numbers reflect the scale of demand for this approach: over 15,000 professionals served across 200+ cities in India, with a growing international client base across the UAE, US, UK, and Australia. FUME reports having supported over 12,000 thyroid cases, 8,500+ women with PCOS-related challenges, and over 500,000 kg of collective fat loss across its programmes.

These are not week-long detox bootcamps. FUME’s transformation programmes are high-touch, 1:1 coaching engagements typically spanning 6 months to a year, with daily accountability, personalised protocol design, and regular diagnostic re-testing to track progress and adjust interventions.

The pricing reflects this depth — FUME operates firmly in the premium segment. But the founders argue that the comparison should not be to a diet plan or gym membership, but to the cumulative cost of years of ineffective interventions, specialist consultations, and eventually, chronic disease management.

"People spend lakhs over years on approaches that do not work because they never identified the root cause. We would rather someone invest once in understanding what is actually happening inside their body than keep paying for solutions designed for someone else’s biology." — Dr. Uma Mittal, Co-Founder and Chief Metabolic Health Officer, FUME

The Category FUME Is Trying to Build

FUME’s ambition extends beyond its own client base. The company is increasingly positioning itself as a catalyst for a broader category it describes as diagnostic-informed preventive metabolic wellness — a space it believes sits between conventional healthcare (which focuses on disease treatment) and generic wellness (which focuses on advice without diagnostics).
Central to this category-building effort is the concept of “Metabolic Decoding” — a term FUME has introduced to describe the process of using multi-system diagnostics to understand interconnected factors influencing metabolic health before designing any intervention. The company’s content and thought leadership consistently emphasise themes that challenge mainstream health assumptions: why “normal” blood reports can hide serious metabolic dysfunction, why the same diet produces different results in different people, why gut bacteria influence thyroid function and belly fat, and why genetic individuality should inform nutrition rather than trending diet philosophies.

This educational positioning is deliberate. FUME does not position itself as a replacement for medical care. The company operates in the preventive wellness space and encourages clients to continue working with their physicians for clinical treatment needs. Its role, as the founders frame it, is to fill the diagnostic and lifestyle gap that exists between what conventional medicine tests for and what actually drives long-term metabolic health.
"Conventional medicine asks ‘what is wrong?’ and prescribes accordingly. We ask ‘why is it wrong?’ and address accordingly. Both questions matter. But the second one rarely gets asked." — Dr. Uma Mittal, Co-Founder and Chief Metabolic Health Officer, FUME

Institution First, Not Personality First

One of FUME’s more unusual strategic choices — particularly in India’s wellness market, where personal brands dominate — is its insistence on institution-first brand building.
While both Jagannath Das and Dr. Uma Mittal are visible and active as founders, the company has deliberately positioned FUME itself as the primary brand. Clients come to FUME, not to a specific individual. The clinical team, the diagnostic framework, and the institutional methodology are what drive outcomes — not dependency on any single practitioner.
"We are not building a coaching practice around one person’s personality. We are building a health institution. That means the brand, the system, and the clinical team have to be bigger than any individual — including us." — Jagannath Das, Co-Founder and Director, FUME

This approach also supports FUME’s scalability ambitions. With a team of 20+ professionals including multiple functional medicine doctors, the company can serve a growing client base without the bottleneck that personality-led models inevitably face. It also allows FUME to introduce new clinical specialists, expand into new geographies, and eventually bring in additional leadership without diluting its brand identity.
For a health and wellness industry that frequently rises and falls on the visibility of a single founder, FUME’s institutional positioning represents a deliberate and differentiated long-term bet.

What Comes Next

FUME is currently expanding its presence among NRI (Non-Resident Indian) professionals in the UAE, US, UK, and Australia — a demographic that seeks culturally contextualised metabolic health support but often finds Western functional medicine frameworks poorly suited to Indian dietary patterns, genetics, and lifestyle realities.
The company is also investing in content-led education across LinkedIn, YouTube, Instagram, and its own blog (fume.fit), with a focus on metabolic literacy and challenging the oversimplified health narratives that dominate Indian public discourse.
At a time when India faces what many public health experts describe as a metabolic health crisis — driven by rapid dietary changes, sedentary professional lifestyles, and a healthcare system built primarily around acute care rather than prevention — FUME’s argument is straightforward: prevention that works requires understanding that goes deeper than a standard blood test.
Whether that argument reshapes how India thinks about preventive health remains to be seen. But with over 15,000 transformations and a growing body of client outcomes, FUME is making a credible case that the future of metabolic health belongs to those who decode first and intervene second.
