    How Did We Get Here? The Rise of Obesity in the UK

    Show notes In 1950, fewer than 1% of the UK population were obese. Today it’s more than 30%. So what changed? In this episode we’re joined by Professor John Deanfield CBE, Professor of Cardiology at University College London. He is one of the world’s leading cardiometabolic specialists, a steering committee member for the landmark SELECT trial, the UK government’s first champion for personalised prevention, and a trustee of Our Future Health. This is the first in a series of conversations. Here we look at how obesity became the biggest driver of ill health in the population, and why it’s a medical issue, not a cosmetic one or a failure of willpower. In this episode: What BMI measures, and where “overweight” ends and “obese” beginsWhy the UK and US have done worse than countries like France and JapanHow changes in food, work, cities and lifestyle have driven a population-wide shiftThe health cost: diabetes, heart disease, kidney disease, cancer and dementia, and how obesity lowers the chance of reaching 70Childhood obesity, “the elephant in the room”, and the WHO prediction that half of children born today will be overweight or obese adultsWhy Jamie Oliver’s school meals campaign showed there’s no single fix“Investing in your arteries”: why prevention works like saving for retirementOur Future Health, the UK’s largest health research programme, and how it builds on UK BiobankThe future of the NHS, social care and living longer in good health Key takeaway: Managing your weight is about more than how you look. It shapes how well you live and how long you live. It’s an investment in your long-term health.

    In this episode of the Dokkcast, host Nara sits down with Professor Piers Daubeney, a world-renowned Consultant Paediatric and Fetal Cardiologist at the Royal Brompton Hospital and Imperial College London. Together, they untangle the complexities of Postural Orthostatic Tachycardia Syndrome (POTS)—a frequently misunderstood condition that primarily affects teenagers and young adults.

He highlights the crucial differences between pediatric and adult POTS, details the standard diagnostic toolkit (including ECGs, Holter monitors, and tilt table tests), and outlines a structured ladder of treatment. From simple lifestyle shifts like increased salt intake and targeted hydration to advanced pharmaceutical interventions like Midodrine and Ivabradine, this episode provides a comprehensive roadmap for patients, parents, and healthcare providers.

    The Science of Song & Speech: Unlocking Vocal Health with Leading Laryngologist Declan Costello

    What actually happens when we speak, sing, or lose our voice entirely? In this episode of the Dokkcast, host Nara is joined by Mr. Declan Costello—one of the UK’s leading ENT surgeons, laryngologists, and a classical singer himself. Declan demystifies the complex anatomy of the vocal folds, explaining how a simple "buzzing" sound is modulated into the rich timbres of speech and song. Drawing from his unique dual background as a Cambridge choral scholar and a specialist surgeon, he shares vital insights into vocal pathology, the profound impact of emotion on speech, and why the aging voice is a "use it or lose it" muscle. Whether you are a professional performer or someone who simply relies on your voice for everyday communication, this episode is an essential masterclass in vocal care, debunking common myths (like gargling salt water) and highlighting when a hoarse voice is actually a sign to see a specialist.

    The Truth About GLP-1 Weight Loss: Nutrition, Muscle Loss & Ozempic with Dietitian Marcela Fiuza
