  • How to slash your dementia risk in 12 weeks

    How to slash your dementia risk in 12 weeks
    Mar 2 2026
    Around the world, more than 50 million people are living with some form of dementia – a number expected to triple by 2050 as populations age. But the thing is, dementia is often talked about as a kind of genetic lottery. You either get lucky and escape it, or unlucky and develop it. But what if that framing is wrong? What if far more of our brain health is within our control than we’ve been led to believe? Our guest today is Dr Majid Fotuhi, a neuroscientist who has spent decades treating and studying people with cognitive impairment. His message is a bold one: dementia is largely preventable – not with a miracle pill or silver-bullet treatment, but through the way we live. The 12-week programme he and his team have developed has helped his patients improve their memory, regain independence, and even grow new brain connections. Today, he talks us through the essentials of the programme – and what it really takes to stay sharp for life. Learn more about your ad choices. Visit podcastchoices.com/adchoices

  • Why connecting with others is vital for our mental health

    Why connecting with others is vital for our mental health
    Feb 27 2026
    Statistics show that half of us will experience a mental health condition of some kind by the time we turn forty. Could this be due to the increasing pressures and looming crises we’re currently facing in the modern world, overstimulating natural responses in our brains and bodies that have evolved over hundreds of thousands of years to protect us from threats? In this episode, we’re joined by Dr Joanna Cheek, a psychiatrist, psychotherapist and clinical professor based at the University of British Columbia’s Faculty of Medicine, to talk about her latest book, It’s Not You, It’s the World – A Mental Health Survival Guide for Us All. She tells us how the system of alarm signals in our brains is being increasingly triggered by the rapidly changing circumstances we find ourselves in, how this is hijacking the push and pull of our natural risk/reward systems, and why connecting more deeply with the rich tapestry of the people and cultures we share the world with can help us all bring our lives back into balance.

  • How metabolism really affects your health, weight and wellbeing

    How metabolism really affects your health, weight and wellbeing
    Feb 23 2026
    Whether we’re working at a desk in an office, running a marathon or even asleep in bed, our bodies are host to thousands of chemical processes that are continually converting the food we eat into energy and repairing our bones, muscles and organs. Collectively these processes are known as the metabolism. But how are they affected by our genes, lifestyles and diet, and what can we do to make sure everything stays running smoothly? In this episode, we’re joined by Javier Gonzalez, a professor of nutrition and metabolism based at the University of Bath. He breaks down the links between our metabolisms and body types, tells us why our metabolisms aren’t necessarily fixed for life, and explains why it’s almost impossible to out exercise a poor diet if you’re looking to drop a few kilos.
