  • How learning to savour flavour can transform your health | Spencer Hyman

    How learning to savour flavour can transform your health | Spencer Hyman
    Nov 6 2025
    Is flavour just a sensory experience? Or the secret key to eating for health? In this episode, Spencer Hyman, flavour expert and co-founder of Cocoa Runners, joins Professor Tim Spector, world-leading scientist in nutrition and gut health, to uncover how the food industry manipulates taste to make us overeat, and how rediscovering real flavour could transform our wellbeing. Spencer reveals the fascinating science of flavour and why we “taste” with our noses, how chocolate became the world’s first hyper-palatable food, and why modern diets are full of fake flavours designed to make us eat faster. Tim explains how “big food” exploits the brain’s reward system to override fullness signals, creating products that keep us hooked - and what we can do to fight back. For listeners curious about how to rebuild a healthy relationship with food, this episode includes a practical guide to retraining your taste buds. Spencer and Tim share tips on how to eat more slowly, savour each bite, and use flavour as a natural marker of nutrient-rich, satisfying foods. Could learning the language of flavour be the most powerful way to eat better - without restriction?

    Tired and hungry? How the wrong breakfast will ruin your day | Prof. Benjamin Gardner & Professor Tim Spector
    Oct 23 2025
    Get 6+ FREE breakfast recipes from nutrition experts: https://zoe.com/breakfastguide Why do so many of us eat a "healthy" breakfast like cereal or muesli, only to feel hungry, tired, and foggy by 11 AM? And why is it so hard to break this routine, even when we know it’s not working? In this episode, Jonathan Wolf speaks to Professor Ben Gardner, a leading expert in habit psychology, and Professor Tim Spector, a world-leading scientist in nutrition and gut health. They explore the science behind why our breakfast routines are broken, how they set us up for a daily blood sugar rollercoaster, and what to do to fix things. Tim breaks down the latest science on common breakfast foods, explaining why most cereals, muesli, fruit juices, and "high-protein" options are failing us, leading to energy dips and mood changes. Ben explains the psychology of why we're stuck. He reveals why bad habits run on autopilot, why our environment is more powerful than our willpower, and busts the persistent "21-day" myth, explaining how long it really takes to form a new habit.
