  • Why understanding what makes us hungry is key to weight loss

    Why understanding what makes us hungry is key to weight loss
    Mar 6 2026
    Chances are that if any of us are looking to drop a bit of excess weight, the first thing we’ll attempt is to cut down the number of calories we’re consuming. For decades, we’ve been told that balancing the number of calories we put into to our bodies with the energy that we burn can help us to maintain a healthy weight. While this is true, could it be that we’re putting our attention and effort in the wrong place and that taking a bigger picture view of the factors that motivate our appetite is likely to be a much more successful strategy? In this episode, we’re joined by Dr Jason Fung, a physician and best-selling author based in Toronto, to talk about his latest book, The Hunger Code – Resetting Your Body’s Fat Thermostat in the Age of Ultra-processed Food. He talks us through the three key drivers that control our feelings of hunger, how our hormones are deeply connected with our appetites, and how the environments we live in have a profound effect on the food we eat.

  • 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.
