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 cut back on, you'll learn what raises your cholesterol, and why the type of fat you eat matters more than how much of it you eat. You’ll leave the episode with some practical food swaps to protect your heart and live longer.

Have you swapped butter for "low-fat" alternatives loaded with sugar? Could that choice be working against your heart?

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 these claims are actually supported by science?

Professor Daniel Davis joins me to explain how our immune system truly works, and what the evidence says is the best ways to support it.

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 insulin does in your body, why you need it to live, and what happens when it stops working properly.

By the end of this episode, you will understand how to spot the warning signs and have practical steps you can take to protect yourself.

If your last blood test came back "normal," how confident are you that it tells the whole story? Are you overlooking one of the biggest drivers of chronic disease?

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 Marion Nestle joins me to explore how additives became so deeply embedded in modern food production — and why, now more than ever, it’s essential for you to understand the things that are hiding in your food.

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.

Jimmy explores why two people can weigh exactly the same and carry completely different amounts of this hidden fat, what it is, where it hides and why it matters.

By the end, you'll have a completely new understanding of body fat, and what it really means for your long-term health.

If your weight has stayed exactly the same for years, what do you think is happening underneath it?

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 your risk of heart disease and even heart attacks.

Dr. Nour Makarem joins me to explore the powerful connection between sleep and heart health - and why both too little and too much sleep is a cause for concern.

Why can’t you lose weight, and why do modern diets fail?

Today, Harvard professor Daniel Lieberman explains how evolution shapes hunger, body fat, food cravings, and modern food mistakes. You will learn why eating well can feel so hard in today’s food world.

Using themes from Daniel’s new book, Fed Up: What Evolution Reveals about Food, Diet and Eating Well, we explore how our modern food environment explains weight gain, failed diets, and confusion about what to eat. We discuss calorie counting, ultra-processed food, hunger, and why there may be no single “best” diet for everyone.

By the end of the episode, you’ll have some simple ways to make better food choices and will know how to make healthy choices easier.

If your body evolved for a world where food was scarce, what does that mean for how you eat today?

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 is actually backed by science?

I’m joined by Dr. David Seres to help cut through the confusion and uncover what the science really says about vitamin C, vitamin D, and even the mysterious multivitamins.

Could 12 everyday high-fibre foods really help lower your risk of heart disease, dementia and some cancers? 

The world is obsessed with protein, but fewer than 1 in 10 people eat enough fibre. But this year, fiber is making an unexpected comeback.

In this episode, legendary chef Hugh Fearnley-Whittingstall and ZOE’s Chief Scientist Professor Sarah Berry ask whether fibre is another food trend or a powerful part of our diet that we have overlooked.

Taking inspiration from Hugh’s new book High Fibre Heroes, they explore how fibre feeds your gut microbes, helps you feel full and slows the release of sugar into your blood. And, by the end of the episode, you’ll know how to eat more fibre without costly ingredients or difficult recipes, and how to turn familiar foods into simple meals packed with flavour.

Are you buying more protein while overlooking the foods your body may need most? The answer could already be in your cupboard, freezer or fridge.

Today we’re talking about fat loss.

For decades, we’ve been chasing the perfect weight loss diet. From Atkins to carnivore, countless trends have promised remarkable results, yet fail the test of time.

So how do we cut through the noise and find a formula that actually works?

In this episode, I’m joined by nutrition researcher Alan Aragon and Professor Sarah Berry to unpack the science behind sustainable fat loss, and explain why, in some cases, the first step toward losing weight might actually involve gaining a little first.

How can you enjoy sugar without gaining weight, fuelling cravings or crashing later in the day? The answer, surprisingly, is not to cut it out.

In today’s episode, Professor Tim Spector and Professor Sarah Berry discuss which forms of sugar affect your blood sugar levels most, and what small changes you can make today to reduce the impact. They also explore how sharp blood sugar spikes and dips may affect hunger, energy, inflammation and long-term health.

By the end of the episode, you’ll know how to spot hidden sugars, how to avoid the afternoon slump and energy crashes, and, most importantly, how to enjoy cake with less impact on your blood sugar.

Sugar is not the enemy. But could a few small changes help you enjoy sweet foods without the cycle of cravings, hunger and energy crashes?
