Why “Normal” Blood Tests Don’t Always Mean You’re Healthy | Dr Rhea Kotecha
Featuring Dr Rhea Kotecha Instagram: @drrheakotecha Can your blood tests look "normal" while problems are already developing beneath the surface? In this episode of the Live More Podcast, I sit down with Dr Rhea Kotecha, a UK-trained doctor working in longevity, preventative medicine, functional medicine, clinical nutrition and metabolic health. After working on the NHS frontline during COVID, Rhea became increasingly interested in what happens before someone becomes a patient — and how nutrition, metabolic health and lifestyle can influence our long-term health. We explore: • Why "normal" blood tests don't necessarily tell the whole story • Fasting insulin, HbA1c and metabolic health • The 12 hallmarks of ageing • Insulin resistance and metabolic flexibility • Gut health, Akkermansia and the microbiome • Fibre and how much we should be eating • Brown vs white rice and choosing organic produce • Fasting, breakfast and meal timing • GLP-1 drugs and preserving muscle • ApoB, LDL cholesterol and cardiovascular risk • Lp(a) and genetic cardiovascular risk • CAC scans and what a score of zero can and can't tell us • Statins and cardiovascular prevention • Biological age testing and epigenetic clocks • Sleep and circadian rhythm • Relationships, purpose and emotional health • AI and the future of personalised longevity medicine KEY TAKEAWAY Longevity isn't about chasing immortality or perfect biomarkers. It's about identifying risk earlier, improving what we can control and building the physical and emotional resilience to stay healthier for longer. The fundamentals still matter: nutrition, fibre, movement, metabolic health, sleep, relationships and purpose. RESOURCES MENTIONED EWG Dirty Dozen™ & Clean Fifteen™ Rhea discusses using the Environmental Working Group's Shopper's Guide to help prioritise which produce she chooses organic. The guide ranks conventionally grown produce according to pesticide residues. Bananas, avocados, pineapple, mangoes and kiwi are among the 2026 Clean Fifteen. https://www.ewg.org/foodnews/ RESEARCH • López-Otín C et al. Hallmarks of Aging: An Expanding Universe.
