Functional Medicine MD: What 5,000+ Patients Taught Him About Root Cause Medicine

Functional Medicine MD: What 5,000+ Patients Taught Him About Root Cause MedicineIn this episode of Return on Health, we speak with Dr. Peter Martin, physician, former CNS pharmacology researcher, and founder of FunMed, one of Europe’s leading functional medicine clinics.Peter spent around 15 years in pharmacology research before his own burnout pushed him to look beyond the conventional model of symptom control. What started as a personal search for recovery became a data-driven clinical model built around root cause medicine, extensive biomarker testing, gut health, metabolism, and chronic disease prevention.We talk about what functional medicine actually means, why chronic disease often needs a different care model, and what Peter has learned from treating more than 5,000 patients. He explains why fasting insulin may be one of the most overlooked markers in modern healthcare, how low-grade inflammation is often connected to gut health, and why normal lab results do not always mean someone is truly healthy.We also get into the controversial parts: large biomarker panels, false positives, red meat, vegan diets, anti-nutrients, carnivore diets, and the weakness of much nutrition research. Peter also shares why he believes functional medicine could become part of the European healthcare system, especially if reimbursement shifts from visits and procedures toward actual health outcomes.This episode covers:What 5,000+ patients taught himWhy fasting insulin is often missedHow root cause medicine could change careTopics discussed:00:00 Introduction01:00 What FunMed does differently02:00 Real-world data from 5,000+ patients03:30 From CNS pharmacology to functional medicine07:00 Root cause medicine vs symptom control10:30 Precision health in Sweden and Germany15:30 Why FunMed tests around 200 biomarkers21:00 False positives and the problem with large panels28:00 Fasting insulin and insulin resistance31:00 Low-grade inflammation and gut health35:30 Low-carb and ancestral nutrition41:00 Vegan diets, nutrient deficiencies, and bio-individuality49:30 Red meat, nutrition research, and epidemiology56:00 Functional medicine and insurance coverage59:00 Rapid fire: biomarkers, magnesium, carnivore diet, healthcare reformGuestDr. Peter MartinPhysician, former CNS pharmacology researcher, founder of FunMed, and one of the leading voices trying to bring functional medicine and precision health into European healthcare.Guest linksLinkedIn: https://www.linkedin.com/in/peter-martin-31b23342/FunMed: https://www.funmed.se/?srsltid=AfmBOorlgUNnEK1ba7p_zIxug35sx3YMSq6PmYiufq6xJH1VAQ-EiQc0Return on Health is available wherever you get your podcasts.If you enjoyed this episode, leaving a 5-star rating on Spotify helps us bring more honest conversations about health, longevity, and medicine to more people.
