Most replayed moment: Sleep myths that are ruining your rest | Dr Sophie Bostock
Sleep. It’s a bizarre process when you think about it. We lie down, close our eyes, and before we know it, we’re waking up the next morning with a head full of hazy dreams.
Because of its mysterious nature, sleep has long been surrounded by all kinds of strange ideas and theories about what might help or harm it. From cheese causing nightmares to turkey making you sleepy.
So today I’m joined by
How to build muscle & stay strong at any age: The surprising links between your gut health, strength training and healthy ageing | Prof Claire Steves & Prof Tim Spector
How do you build muscle and stay strong as you age?
For most of us, muscle loss starts in our 30s. It’s easy to think that you can combat this and stay strong into old age by strength training and eating plenty of protein.
Exercise and macros matter, but scientists are uncovering another important piece of the puzzle - a direct connection between your gut health and healthy ageing. It could chan
Most replayed moment: How to stop fighting your body clock | Prof. Debra Skene
Every one of us runs on a biological rhythm - a finely tuned system that controls when we feel alert, when we feel tired, and even how we process food.
But here’s the problem: modern life doesn’t always respect this rhythm. Late nights, early alarms, and irregular meals put many of us out of sync with our own biology.
I’m joined by Professor Debra Skene to explain why this mismatch matters, and
How to eat to lower inflammation - the top 5 foods to boost energy, stop pain, and to live longer | Prof Luke O’Neill
Most of us think of inflammation when an ankle swells or a cut turns red. It’s our body’s immune system, and without it, we couldn't fight infections or repair injuries.
But when it stays switched on, this chronic inflammation can drain your energy, can affect your health over the years, and even lead to heart disease. Eventually, 1 in 3 of us will develop an inflammatory disease.
In today
Most replayed moment: The hidden dangers of hearing loss | Prof. Marcelo Rivolta
The world around us is louder than ever. From booming speakers to roaring traffic, our ears can take quite a beating. But have you ever stopped to consider the long-term impact of all this noise?
Because hearing loss isn’t just about your ears. Emerging research suggests it could also affect your brain health in surprising ways.
I’m joined by Professor Marcelo Rivolta to explore how noise exposu
Inside Tim Spector’s weekly food shop - 6 grocery rules to lower your blood pressure, cholesterol, and heart disease risk | Prof Tim Spector & Prof Sarah Berry

Today, Professors Tim Spector and Sarah Berry, world-leading experts in nutrition and diet, share the six rules they use for their own weekly grocery shopping. They cover which food labels are worth trusting and which are just marketing scams, how to ma
Most replayed moment: What your wearable is really telling you | Dr Malcolm Finlay
From smartwatches to fitness trackers, more of us than ever are monitoring our health in real time. With just a glance at our wrist, we can check our step count, sleep quality, heart rate and, more recently, something called HRV.
But what do these numbers actually mean? And more importantly, how can we use them to improve our lives?
I’m joined by Dr Malcolm Finlay to break down the data behind t
Is your gut the secret to anti-aging? 6 science-backed ways to boost your bone strength, muscle, and balance | Prof Elaine Dennison
Picture the sound of a bone snapping - the kind of sound that makes you wince - and ask yourself how often you’ve thought about your bone health.
Most of us only think about bone density when something breaks. Until then, your bones stay almost invisible, carrying you through every day.
In today’s episode, Professor Elaine Dennison, a world-leading expert in bone health, explains why that needs
Most replayed moment: How to build a better breakfast | Prof. Ben Gardner & Tim Spector
We’ve all heard the saying: Breakfast is the most important meal of the day. And while it may sound like a cliché, there’s some truth to it. Because for many of us, breakfast is the one meal we keep the same - day after day, morning after morning.
This consistency means our breakfast choices have a powerful influence on our long-term health.
So, today I’m joined by Tim Spector and behaviour exp
The science behind food that isn’t food, why you love it and why you should not fear it all | Prof Tim Spector & Prof Sarah Berry
Are some of your "healthy" foods actually high-risk ultra-processed foods?
For decades, nutrition advice seemed relatively straightforward. Eat less sugar. Less salt. Less saturated fat. Then it all fell apart.
In today’s episode, we examine the research that has forced us to rethink what makes food harmful in the first place. Two of the world’s leading nutrition scientists, Professor Tim
Most replayed moment: The hormone that controls your weight | Dr Andrew Jenkinson
Floating through all of our bodies is a complex network of hormones. You can think of it as an internal postal service, delivering vital messages and instructions to different organs and systems.
But what happens if these messages get intercepted, mixed up, or worse, not delivered at all?
In this episode, Dr Andrew Jenkinson tells us about a hormone that plays a crucial role in weight regulation
The secret to coping with stress - how to protect your brain and body, and feel calmer now | Prof Carmine Pariante
Growing up, many of us were taught to just stay calm and carry on - as if stress was all in the mind, with no real effect on the body. But chronic stress can change your brain, raise your risk of heart disease, and even shorten your life.
In this episode, we ask: what happens when a stress response built to last minutes never switches off?
Today, Professor Carmine Pariante, one of the worl
Most replayed moment: The hidden battle inside your gut | Tim Spector & Nicola Segata
Today we’re talking about gut microbes.
Professor Tim Spector often refers to the microbes in our gut as ‘mini pharmacies’. This is because they provide us with powerful chemicals that help support our health.
But not all gut microbes are on our side. In fact, there’s an ongoing battle in our digestive system between the beneficial bugs and those that wish to do us harm.

The 5 best food swaps to lower cholesterol, protect your heart and to live longer | Dr. Alice Lichtenstein
Is fat good or bad for your heart? For decades, we blamed fat and cholesterol for clogged arteries and heart attacks. Now you choose low-fat yogurt to protect your heart, while others cook with beef tallow.
In this episode, Dr. Alice Lichtenstein, a world-leading expert on dietary fat and heart health, helps settle the debate.
Dr. Lichtenstein explains which fats protect your heart and which to
Most replayed moment: Can you really boost your immune system? | Professor Daniel Davis
Today we’re talking about the immune system.
It’s one of the most important systems in our body, yet it’s also one of the hardest to understand. You can’t see it, you can’t feel it working, and there’s no simple way to measure whether it’s strong or weak.
But when it fails, we certainly notice.
Everywhere we look, supplements and superfoods promise to ‘boost’ our immune system. But how many of
5 ways to control your blood sugar, reverse insulin resistance, and reduce your heart disease risk | Prof Rob Semple
1 in 4 people have insulin resistance, which quietly raises your risk of heart disease and cancer, often without any change in your blood sugar.
And most of those who have it have no idea. It can remain completely hidden for years, with no obvious symptoms and no warning signs… But it can be reversed.
Today, Professor Rob Semple, a world-leading expert on insulin resistance, explains what insuli
Most replayed moment: The things hiding in your food? | Professor Marion Nestle
Today we’re talking about food additives.
Take a look at the back of some ultra-processed packaged food and you’ll see a long list of unfamiliar ingredients. Complex, sciencey sounding names that most of us can barely pronounce.
These are called additives. But what exactly are they? How are they tested? And, most importantly, are they truly safe for us to eat?
Food policy expert Professor Mario
How to shrink the dangerous fat linked to heart disease and cancer in 12 weeks | Prof Jimmy Bell
There's a hidden fat that matters more for your health than your weight. This is visceral fat: it wraps around your organs, raises your risk of heart disease and cancer, and builds up even in people who look slim and healthy.
In today’s episode, Professor Jimmy Bell, a world-leading expert in measuring visceral fat, explains how we can shrink this dangerous belly fat in just 12 weeks.
Most replayed moment: Why sleep may be the key to heart health | Dr Nour Makarem
Today we’re talking about sleep.
The more scientists study sleep, the clearer it becomes that it’s not just about resting our bodies - it’s much more than that. In fact, sleep is the foundation upon which a healthy diet, exercise, and overall wellbeing are all built upon.
So what happens when that foundation is shaky?
Recent research suggests that poor sleep quality may significantly increase y
The evolutionary science behind why you can’t lose weight and how to avoid 5 modern food mistakes | Prof Daniel Lieberman
Why can’t you lose weight, and why do modern diets fail?

Using themes from Daniel’s new book, Fed Up: What Evolution Reveals about Food, Diet and Eating Well, we explore how our modern food enviro
Most replayed moment: Do you really need vitamin supplements? | David Seres
Today we’re talking about vitamins.
Walk into any pharmacy or supermarket and you’ll find a shelf stacked with brightly coloured jars promising better immunity, stronger bones and sharper minds. Of course, I’m talking about vitamin supplements.
But despite looking like medical products, supplements aren’t held to the same rigorous testing standards as medicines. So how much of what they promise

Most replayed moment: Why muscle gain matters more than weight loss | Vonda Wright
Today we’re talking about muscle mass.
For many people, losing weight is the ultimate health goal. However, focusing solely on lowering the number on the scale often means overlooking something crucial: muscle mass.
We know that increasing muscle makes us stronger, but it also plays a surprising role in metabolism and helps keep unwanted fat at bay.
Dr. Vonda Wright joins me to explain why impr

Most replayed moment: Omega-3: heart health hero or overhyped? | Dr. Bill Harris and Professor Sarah Berry
Today, we’re talking about Omega-3.
Omega-3 fats have been celebrated, scrutinised, and debated for decades. While some research points to remarkable heart health benefits, other studies suggest they can actually raise the risk of cardiovascular disease.
So where does the science stand today? Should we supplement, rely on food, or rethink our approach to omega-3 completely?
Dr. Bill Harris and
Is eating like our ancestors the key to better health? What the Paleo diet gets right, and the 5 ancient diet claims that are dangerously wrong for your heart and gut health | Dr James Cole & Dr Federica Amati

Most replayed moment: What The Science Says About Supplements | Prof Tim Spector & Prof Sarah Berry
Today, we’re talking about supplements.
We’ve all seen them; the multivitamins, the fortified foods, the neatly packaged powders promising improved energy, immunity and longevity.
Supplements boast bold claims, however, it’s hard to know if they’re genuinely helpful or just well-marketed.
Professor Tim Spector and Professor Sarah Berry join me to unpack why supplements exist, what the science

Most replayed moment: The Impact of Ultra-Processed Food on Young People | Dr Andy Chan
Today we’re exploring the impact of ultra-processed foods on young people.
One of the big reasons ultra-processed foods have become so widespread is convenience. They offer quick, easy meals for people short on time - and few groups are more time-pressed than parents trying to feed young children.

Tired, anxious, gaining weight? It could be your hormones | Dr Helen O’Neill
