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.

🥑 Make smarter food choices. Become a member at http://zoe.com  Have you ever wondered why you can lose weight on a diet, only for it to come back with a vengeance? If you’ve blamed yourself for a lack of willpower, our guest today argues you’ve been misled. The old mantra of “eat less, move more” is failing us, and the key to understanding why lies deep within our biology. In this episode, Jonathan is joined by Dr. Andrew Jenkinson, a bariatric surgeon and author with decades of experience in the science of metabolism. Dr. Jenkinson dismantles the calorie-counting myth and explains the powerful biological system that controls our weight: the "set point." He reveals how our modern diet and lifestyle have broken this system, but also provides a clear, science-backed path to fixing it. Dr. Andrew Jenkinson is a consultant bariatric surgeon and the author of Why We Eat (Too Much): The New Science of Appetite. In this episode, you’ll learn: Why the idea that weight loss is simply about willpower is a damaging myth. The science of the "weight set point" and how your brain fights to keep you at a certain weight. How your metabolism acts like a "dimmer switch," slowing down to prevent weight loss when you diet. The crucial role of hormones like leptin and insulin, and why our modern diet causes "leptin resistance" — the reason your brain can’t tell it’s full. How yo-yo dieting can actually raise your set point, making you heavier in the long run. A practical, step-by-step plan to lower your set point by changing what you eat, not just how much. The truth about new weight-loss drugs like Ozempic and their long-term effects.

Today, we’re talking about plants. For years, our diets have been guided by a simple three word slogan: ‘five a day’. While it’s well established that eating fruit and vegetables is good for us, some experts believe the ‘five a day’ message puts too much emphasis on quantity, and not enough on variety. So, is time to adjust our guiding plant principle? I’m joined by Professor Tim Spector and chef Hugh Fearnley-Whittingstall, who advocate for a new goal: eating 30 different plants each week. Together, we’ll explore why diversity is key for your microbiome and share some delicious ways to bring more plants onto your plate. 🌱 Try our new plant based wholefood supplement - Daily30+ *Naturally high in copper which contributes to normal energy yielding metabolism and the normal function of the immune system 📚 Books from our ZOE Scientists: The Food For Life Cookbook by Prof. Tim Spector Food For Life by Prof. Tim Spector Every Body Should Know This by Dr Federica Amati Free resources from ZOE: Live Healthier: Top 10 Tips From ZOE Science & Nutrition  Gut Guide - for a healthier microbiome in weeks Have feedback or a topic you'd like us to cover?

Is your smartwatch just a fun gadget, or a serious medical device?  In this episode, Jonathan Wolf is joined by Dr. Malcolm Findlay, a leading consultant cardiologist, to explore the powerful health data available on your wrist. They decode the most misunderstood metric, Heart Rate Variability (HRV), and reveal how your wearable can provide clinical-grade insights into your heart's health. Dr. Findlay explains the counter-intuitive science behind HRV — why more ‘wobble’ in your heartbeat is a sign of good health — and breaks down the two opposing nervous systems that control it. He shares the latest on how these devices can accurately detect serious conditions like atrial fibrillation and why he, as a cardiologist, trusts the ECG function on a consumer smartwatch to make diagnoses. For listeners who track their own data, this episode is a practical guide to what your numbers actually mean. Dr. Findlay explains how to interpret your personal HRV trends, what constitutes a significant change, and when you should use the ECG feature. He also debunks common myths about heart rate zones, revealing the level of exercise intensity that truly benefits your long-term health. The episode concludes with an empowering look at how this technology is shifting control into our own hands. Can a simple alert from your watch really help prevent a catastrophic event like a stroke?

We’ve all been there: tossing and turning, checking the clock, and stressing about not getting enough sleep. But what if the secret to a good night’s rest isn’t in a pill or a product, but in changing your mindset and daily habits? In this episode, we’re joined by Dr. Sophie Bostock, a leading sleep scientist and founder of The Sleep Scientist. Sophie has dedicated her career to helping people understand the science of sleep and how to build lasting, healthy habits. We dive into what really happens when we don’t get enough sleep, from the psychological effects on our willpower and relationships to the physiological impacts on our long-term health. Sophie debunks common myths about blue light, alcohol, and cheese, and explains the critical difference between occasional poor sleep and true insomnia. And introduces us to Cognitive Behavioral Therapy for Insomnia (CBT-I), explaining why it’s a more effective long-term solution than sleeping pills.

Davis, MBE — a leading expert on immunology and Head of Life Sciences at Imperial College London. Daniel has published 145 scientific papers, authored four best-selling science books, and spent 25 years researching how our immune system works. He even helped discover the immune synapse, a breakthrough that changed our understanding of immunity. Daniel explains how your immune system really works, why it’s connected to mental health, and how it can even detect cancer cells. He also clears up common myths and shares what genuinely helps keep your immune system strong through the winter months — and what won’t make a difference. By the end of the episode, you’ll know the practical, science-backed steps you can take to reduce your risk of colds and flu this winter without wasting money on products that don’t deliver.

We’re told vitamins are essential for our health. That they boost our immune systems, fight fatigue, and protect us from disease. But what if most of it isn’t true? In the 20th century, vitamin supplements were hailed as a breakthrough, curing diseases like scurvy and rickets. But that success story took a turn. In the US, a law passed in 1994 — helped by a Hollywood ad campaign — removed almost all oversight from the supplement industry. Since then, a $40 billion business has grown in the shadows. One where marketing beats science, and health claims are made with barely any evidence. Dr. David Seres is Director of Medical Nutrition and a Professor at Columbia University’s Institute of Human Nutrition. David is known for calling out pseudoscience and misinformation, and promoting critical thinking and an evidence-based approach to health. For over 25 years, he’s worked as a physician nutrition specialist, caring for critically ill patients who rely on life-saving nutrition support.

Heart disease is the world’s biggest killer—and it often strikes without warning. It’s responsible for around 1 in 5 deaths in the US. While these figures are deeply worrying, heart disease is not inevitable.  Decades of research have unearthed many of the risk factors associated with heart health, like poor diet or a sedentary lifestyle. In this episode, Dr. Nour Makarem outlines the latest scientific discoveries in this field and unveils some less-familiar risk factors. Drawing from large-scale population data and the latest wearable tech, she uncovers what makes heart disease so hard to spot, and what we can do today to prevent it.  Nour is a cardiovascular epidemiologist at Columbia University, whose research focuses on how our behaviors—like sleep, stress, and daily rhythms—impact heart disease risk. Her research has helped shape the American Heart Association’s Essential Eight guide to heart health.

Those long, unpronounceable ingredients at the bottom of food labels—what are they really doing to your health? In this episode, we’re joined by Professor Marion Nestle, a world-leading nutrition expert and author of the groundbreaking book ‘Food Politics’. Marion has spent decades exposing how powerful food companies influence what ends up on our plates — and how little regulation may stand in their way. We dive into the hidden world of food additives and the regulatory systems meant to protect us. While the U.S. allows companies to self-certify ingredients as “safe” without independent FDA approval, Europe and the UK take a stricter approach. But does stricter always mean safer? Marion unpacks how these systems differ, which substances might be harming our health, and what consumers can do to reduce their risk. We explore what the science says about additives, inflammation, gut health, and more.

Today, we’re diving into fermentation. If you’re a regular ZOE listener, you’ve probably heard that fermented foods are some of the best things you can eat for your gut health. Packed with beneficial microbes, they’ve been shown to boost everything from digestion to immune function. Still, the idea of at home fermentation - cultivating bacteria and microorganisms in your fridge - can feel a little daunting. More like a science experiment than a culinary adventure. That’s where Sandor Katz comes in. He’s a fermentation revivalist, bestselling author, and the driving force behind a global fermentation movement. So if you're a total beginner or just sauerkraut-curious, this episode will give you the tools, the confidence, and maybe even the craving to get fermenting at home. 🥑 Unwrap the truth about your food 👉 ⁠Get the ZOE app 🌱 Try our new plant based wholefood supplement - Daily30+ *Naturally high in copper which contributes to normal energy yielding metabolism and the normal function of the immune system 📚 Books from our ZOE Scientists:The Food For Life Cookbook by Prof. Tim Spector Food For Life by Prof. Tim Spector Every Body Should Know This by Dr Federica Amati Free resources from ZOE: Live Healthier: Top 10 Tips From ZOE Science & Nutrition  Gut Guide - for a healthier microbiome in weeks Have feedback or a topic you'd like us to cover?

Scientists agree that processed foods are contributing to poor health — but when it comes to ultra-processed foods (UPFs), there’s growing confusion. The term is now used so broadly that it includes everything from crisps and sweets to wholemeal bread and plant-based milks. So what do we really know about the health effects of UPFs? And is the label actually making it harder for us to eat well? In this episode, Jonathan is joined by Dr. Sarah Berry, ZOE’s Chief Scientist. Sarah is a professor of nutrition at King’s College London who has run some of the world’s largest human nutrition studies. Her work explores how different foods — and how they’re processed — impact metabolism, fat storage, and long-term health. Sarah shares insights from her recent global conference talks, breaking down the good, the bad, and the misunderstood sides of ultra-processed food. By the end, you’ll have a clearer, more nuanced view of how to eat for your health — without falling for the hype.

Today, we’re exploring the connection between your gut and your brain. For years, the brain was seen as somewhat detached from other parts of our body, working in isolation above all else. However, emerging research is flipping our idea of the brain on its head. Scientists now know that the gut acts like a ‘second brain’, influencing everything from our mood and memory to our risk of neurological disease. So, have we been neglecting a vital piece of the brain health puzzle?  Joining me to unpack this topic is Professor John Cryan, a world-leading expert in the gut-brain axis.

Omega-3 fatty acids have long been lauded for heart health benefits. Yet, emerging research now points to an even more profound impact, directly on our most complex organ: the brain. Today, we delve into the critical, often misunderstood, role of omega-3s in cognitive function, mental well-being, and even the prevention of neurodegenerative conditions like dementia. We are joined by Dr. Bill Harris, a globally recognised authority in omega-3 fatty acid research. Bill is a Professor at the University of South Dakota and has over 300 peer-reviewed publications. His foundational work includes pioneering studies on fish oil in the 1980s and shaping American Heart Association scientific statements. In this episode, Dr. Harris - along with ZOE's Chief Scientist Professor Sarah Berry - illuminate why most individuals may be operating with suboptimal omega-3 levels, and the tangible implications this has for mood regulation, anxiety, and long-term brain resilience. We navigate nuances between omega-3 types like EPA and DHA, debunk common misconceptions surrounding plant-based sources and mercury content in fish, and explore the precise methods for assessing and improving your own "Omega-3 Index."

In this groundbreaking episode, Jonathan, Tim, and guest researcher Professor Quirijn de Mast explore a landmark clinical trial conducted in partnership with Tanzanian scientists and community members at the Kilimanjaro Christian Medical Centre (KCMC). Published in Nature Medicine, the study investigates what happens when people switch between Western-style eating and a traditional diet from the Kilimanjaro region of Northern Tanzania — rich in fermented foods, legumes, ancient grains, and green vegetables. The results? Rapid, measurable changes to immune function, inflammation, and gut health — with powerful implications for global disease risk.We dive into the science behind millet porridge, fermented banana beer, and the fibre-rich meals that Tanzanian communities have eaten for generations. Quirijn shares insights from his 20-year collaboration with local researchers. This episode explores scientific research on traditional East African diets and inflammation, led by Quirijn in close collaboration with Tanzanian scientists and participants. As Western scientists and hosts, we are aware of the need for humility when discussing cultural traditions not our own, and we approach this conversation with respect and curiosity. 🌱 Try our new plant based wholefood supplement - Daily 30+ Follow ZOE on Instagram.

What if your blood pressure — even just a little too high — is quietly damaging your brain? What if it’s increasing your risk of a heart attack or stroke, without you ever feeling a thing? In this episode, Professor Tim Spector reveals why blood pressure is one of the most overlooked – and most dangerous – health issues today. He explains why “normal for your age” might not be safe at all, why medication alone isn’t the full answer, and how small, daily changes could dramatically reduce your risk of serious disease. Can your gut microbes raise your blood pressure? Can a banana be as powerful as a pill? Is beetroot juice really three times more effective than cutting salt? You’ll also learn why 80% of the salt we eat isn’t from the shaker, how stress and sleep secretly push your pressure up, and what most doctors still miss when treating hypertension. If you’ve ever been told your blood pressure’s “fine” — or never measured it at all — this episode might change the way you think about your future health.

What if the fatigue, stiffness, and brain fog we blame on aging are actually symptoms of something we can change? In this episode, immune aging expert Professor Janet Lord unpacks “inflammaging” - a slow, chronic form of inflammation that quietly builds in the body as we get older. It’s now believed to drive many of the diseases we associate with aging, from dementia to heart disease. Janet reveals how this invisible inflammation takes hold, how it silently damages the brain, gut, and immune system - and what science says we can do to fight back. Her research has shown that even in your 70s, it's not too late to reverse immune aging. One small change tomorrow could make a measurable difference. Professor Janet Lord is a world leading expert in the biology of aging. She’s published over 200 scientific papers and advised UK health policy. Her groundbreaking work shows how daily habits - especially movement - can reshape the immune system and slow the effects of time. If you want to stay stronger, sharper, and healthier for longer, this conversation could change the way you think about aging. 🥑 Make smarter food choices.

We often associate depression with withdrawal and low energy - but what if it hides behind a packed schedule and staying busy? Board-certified psychiatrist Dr. Judith Joseph joins Professor Sarah Berry to explore high-functioning depression. Dr. Joseph explains how depression gets missed by medical professionals, explaining what’s really happening in the brain. She shares how traditional definitions of depression often overlook people who appear to be coping, leading many to go undiagnosed and unsupported. We discuss how a busy, high-achieving lifestyle can actually mask the symptoms of depression - and even perpetuate it. Dr. Joseph, the first psychiatrist to run a lab focused on high-functioning depression, shares her latest findings on its causes, signs, and long-term impact. ZOE’s Chief Scientist Prof. Sarah Berry explains how food and the gut microbiome may hold the key to reducing these symptoms. If this sounds familiar, Dr. Joseph introduces a quick self-test to help identify high-functioning depression - and outlines five practical strategies to begin healing, and Sarah gives you the foods that could help. 🥑 Make smarter food choices.

Carbs are one of the most misunderstood aspects of nutrition. For decades, they’ve been praised, demonized, and debated. Today, low-carb diets are everywhere, but the reality is more nuanced. While over 80% of the carbs we eat come from low-quality, refined sources, the right kinds of carbs are essential for good health. In this episode, Professor Tim Spector breaks down the difference between good and bad carbs and explains why quality matters more than quantity. He explores how the rise of ultra-processed foods has led to an overconsumption of unhealthy carbohydrates, contributing to energy crashes, hunger, and long-term health issues. He also explains the benefits of fiber-rich carbs, their role in gut health, and why cutting carbs entirely may not be the best approach. The episode also answers common questions about carbs, including the best time to eat them, how to pair them for better digestion, and whether alternatives like almond flour are actually healthier. Tim also shares practical tips, such as why freezing bread might be a simple way to make it better for you. 🥑 Make smarter food choices.

Midlife is often seen as a point of no return for health, but it could be the perfect moment to make a radical change. New research suggests that your gut microbiome holds the key to aging well, protecting you from chronic disease, and even reversing some of the damage from years of poor diet and stress. Few people understand this better than Rich Roll, who went from an overweight, junk-food-addicted workaholic to one of the world’s fittest men - all after the age of 40. Now a plant-fuelled ultramarathoner and bestselling author, Rich shares the wake-up call that forced him to transform his life. He’s joined by Professor Tim Spector, one of the world’s top 100 most cited scientists and professor of epidemiology at King’s College London, who explains why gut health becomes even more important as we age - and how small changes to diet, movement, and daily habits can have an outsized impact later in life. 🥑 Make smarter food choices.

Today we’re discussing fat. It’s a word that carries a lot of weight. It’s a source of social judgment, a driver of insecurities and a tool exploited by companies in targeted marketing campaigns. It’s no surprise that a recent study found over 40% of people in the US have experienced some form of ‘fat-shaming’. But do we really understand fat? What it does, how it forms and why its distribution changes as we age. Prof. Sarah Berry and Prof. Deborah Clegg are here to help us answer some of these questions and change our perception of fat.

Only 12% of American adults are considered metabolically healthy - meaning the vast majority are at increased risk of heart disease, diabetes, and strokes. But what exactly is metabolism, and why does it matter so much for our health? In this episode, bestselling author and health expert Shawn Stevenson joins world-renowned scientist Professor Tim Spector to break down the science of metabolism. They’ll debunk the myth of “metabolic rate” and explain why it’s not just about how fast you burn calories - but how your body processes and uses them. You'll discover how poor sleep, stress, and ultra-processed foods are impacting your metabolic health - and how this sets the stage for weight gain and chronic disease. More importantly, Shawn and Tim will share the simple, science-backed habits that can improve your metabolism, from eating nutrient-dense foods to optimizing movement and sleep. 🥑 Make smarter food choices.

Today we’re exploring what evolution can teach us about exercise. When it comes to doing exercise, there’s often a tug-of-war between our body and brain. Our body craves movement - it wants to be leaner, fitter, stronger. But our brain? Well, that’s a different story. It often dreads the thought of going on a run or lifting weights and will try and find any excuse to avoid doing it. So, why does this conflict exist, and more importantly, how can we overcome it?

Today, we’re putting the spotlight on our brains. As we age certain behaviours often become more noticeable - misplacing keys, struggling to recall names or forgetting why you walked into a room. Most of us have likely seen this happen to someone close to us and may have even seen these patterns develop into more serious conditions like dementia. But are these behaviours just an inevitable part of getting older? Or is there something we can do to prevent them?

How old are you? A better question might be: how old do you feel? While your birthday says one thing, your biological age—the health of your cells—might tell a very different story. And here’s the best part: unlike your chronological age, your biological age can go down. But how? For years, fasting has been celebrated as a key to longevity. Yet the challenge of skipping meals is enough to make most of us shy away. What if you could trick your body into reaping the rewards of fasting—without starving yourself?  This week, we’re joined by Dr. Valter Longo, Director of the Longevity Institute at USC and one of TIME’s 50 most influential people in healthcare. Valter’s groundbreaking research on ageing and his FMD program have transformed how we think about health and longevity.

Think weight loss is all about eating less and moving more? Think again. In this episode, Prof. Giles Yeo reveals why calorie counting isn’t just inaccurate—it could actually make weight management harder. He explains why the popular “calories in, calories out” method doesn’t add up and explores how factors like genetics, brain signals, and gut health play a major role in shaping our weight. Giles Yeo is a Professor of Molecular Neuroendocrinology at the University of Cambridge and Honorary President of the British Dietetic Association. His research focuses on the influence of genes on feeding behaviour and body weight. Giles is also the author of ‘Gene Eating’ and ‘Why Calories Don’t Count’. Giles shares the surprising impact of ultra-processed foods on how we process calories and why losing weight often feels like a battle against our own biology. With decades of research in his back pocket, Giles shares science-backed advice to help you break free from yo-yo dieting, read calorie labels smarter, and embrace a more balanced, plant-rich diet for long-term health. 🥑 Make smarter food choices.

Artificial sweeteners are everywhere. They hide in cereal, salad dressing – even in health foods. But are they really a guilt-free way to satisfy your sweet tooth? Or is it naive to think that – because they’re zero calorie – they’re free of consequence? New research shows there is a consequence. And it could be massive. Artificial sweeteners may disrupt the delicate balance of bacteria that live in your gut. You could see ripple effects like chronic disease, weight gain and a weakened ability to process real sugar. Today’s guest is at the forefront of this research. For the last decade, Dr Eran Elinav led breakthroughs on the science behind popular sweeteners. He leads The Institute for Microbiome Research at the Weizmann Institute of Science. He’s published over 100 publications in leading scientific journals. And his lab is on the cutting-edge of gut microbiome research.  We’re also joined today by Tim Spector. Tim is one of the world’s top 100 most-cited scientists, a professor of epidemiology, and my scientific Co-Founder at ZOE.  You’ll finish today’s episode knowing what's in your sweetener, how it’s affecting you, and where to turn to satisfy your sweet tooth.    🥑 Make smarter food choices.

A good gynecologist is like a detective. She gathers evidence to diagnose infections. She uncovers the truth behind stages like puberty, pregnancy and perimenopause. Yet many women still feel that their physiology is a mystery.  What if a clue to that mystery hides in our diet? Similar to the gut, certain foods make the vaginal microbiome thrive. New research suggests that the right diet could alleviate symptoms of the most common gynecological diseases. Dr Jennifer Ashton is former Chief Medical Correspondent at ABC News and is a double-board certified OBGYN. She joins us today to discuss ‘nutritional gynecology’, a term she coined after realizing multiple women’s health issues have a direct relationship to nutrition. Alongside Jen is King’s College London professor and ZOE’s Chief Scientist Sarah Berry. Sarah shines light on the growing evidence of the role of nutrition in offsetting uncomfortable, and sometimes dangerous, symptoms of menopause. 🥑 Make smarter food choices.

Over the last two years, there’s been a rise in “immune-boosting” foods, supplements and trends. Today's guest, immunologist Dr. Jenna Macciochi, believes the immune system doesn’t need boosting. Instead, it should be balanced. In this episode, Jenna - a Senior Lecturer in Immunology at the University of Sussex - reveals how your immune system is your body’s housekeeper. Jenna highlights the case for the ‘good bugs’ in our gut microbiome, the role of micronutrients and how our immune system isn’t born, but made. We'll also tackle the age-old question: do we really need Vitamin C supplements? 🥑 Make smarter food choices.
