How to tell if your poo is normal and the 5 warning signs you shouldn't ignore | Dr Trisha Pasricha

Most people think you need to poo every day to be healthy. You don’t. In this episode, we explain how to tell if your poo is normal, the warning signs you shouldn’t ignore, and the gut mistake you may be making on the toilet every day.  Dr Trisha Pasricha, a leading Harvard gastroenterologist, a columnist for the Washington Post and author of the book You’ve Been Pooping All Wrong, explains how your poo, gut health, and disease risk are linked, and when you should see a doctor. Dr Pasricha guides us through why frequency, colour, and consistency all matter, and why there is no single “normal.” You’ll learn how to spot changes that could signal disease, including early warning signs linked to cancer and long-term brain health. You’ll hear simple advice you can use straight away. This includes how to recognise your normal pattern, what changes to look out for, and how to avoid the common toilet habit that may affect your gut. Are you looking at your poo every day? And, if not, what might you notice if you did? 🌱 Try our science-backed and tasty wholefood supplement Daily 30 Get our brand-new app and Gut Health Test designed by world-leading gut health and nutrition scientists to build healthy eating habits 👉 Join ZOE Follow ZOE on Instagram.

The first 1000 days: The 5 ways early nutrition determines your future risk of obesity and heart disease | Prof Lucilla Poston & Dr Federica Amati

The blueprint for your life starts much earlier than you realise - long before you took your first breath, before your heart beat its first beat, before your mum and dad even met.  This is the story of the first 1,000 days of life. From conception to age 2, a window so powerful that scientists now believe it influences our future risk of heart disease, obesity, diabetes, and even how our immune system reacts to the world. In this episode, the world’s leading expert on how childhood nutrition and metabolism shape our long-term health, Professor Lucilla Poston, explains how early nutrition may influence appetite, metabolism, and future disease risk.  Lucilla and ZOE’s Head Nutritionist, Dr Federica Amati, break down what science says about pregnancy, early feeding and the food children eat, and questions how lifelong health is shaped before a child even chooses their first meal. Lucilla offers practical guidance on what matters most and explains key nutrients to consider. They discuss why regular movement may help support healthy blood sugar levels. They also explain what a balanced diet can look like for parents and young children, why babies should try a wide range of whole foods, and why many packaged baby foods may contain far more sugar than parents expect. What small choices can you make today to help shape a healthier future for you, your children, and your children’s children? 🌱 Try our science-backed and tasty wholefood supplement Daily 30 Get our brand-new app and Gut Health Test designed by world-leading gut health and nutrition scientists to build healthy eating habits 👉 Join ZOE Follow ZOE on Instagram.

Today we’re looking at a novel way to improve our mental health. If I’ve learnt anything from hosting this podcast, it’s just how interconnected all the systems in our body are.

With this in mind, let’s shift our focus on mental health. Can we approach it from a different angle?

How to feed the 50 gut bacteria that shrink body fat, calm inflammation and cut cholesterol | Prof Nicola Segata & Prof Sarah Berry

Is gut health just about taking a probiotic? Or could the bacteria in your gut be shaping your body fat, inflammation and cholesterol? In this episode, Professor Nicola Segata, a pioneer of new gut technology, and ZOE’s Chief Scientist Professor Sarah Berry, explain a major breakthrough in gut science. After analysing more than 34,000 microbiomes, the team identified 50 gut bacteria strongly linked to better health. Even more striking, many of them were previously unknown to science. Nicola explains how his team ranked hundreds of gut bacteria to define the “top 50” linked to better health, and explore how these bacteria group into patterns connected to inflammation, blood sugar, heart health and body fat. We uncover how you can improve your overall health in weeks by optimising your microbiome, ask whether probiotics do what we think they do, and examine why plant diversity may matter more than any single supplement. This episode also reveals what happened when these findings were tested in trials, and why the results surprised even the scientists. Are you feeding the right gut bacteria? And, if not, what will happen to your health if you start today? 🌱 Try our science-backed and tasty wholefood supplement Daily 30+ Get our brand-new app and Gut Health Test designed by world-leading gut health and nutrition scientists to build healthy eating habits 👉 Join ZOE Follow ZOE on Instagram.

From oral health and inflammation to vitamin D, sleep, and exercise, Tim explains the daily habits he now prioritises and helps us understand what we should do differently if the science changes. Tim revisits 7 common health beliefs and explains how new evidence has shifted his thinking. He explores the link between oral health, inflammation and brain ageing, and discusses vitamin D, sunlight and omega-3s. The conversation also looks at sleep timing, exercise and how everyday habits interact with our biology.

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

Hormones control almost every system in your body. They are like an orchestra playing, so when one instrument is a little off-key, it affects the whole system. If you feel tired, anxious, or are gaining weight, your hormones may be involved. In this episode, leading reproductive expert Dr Helen O’Neill explains how hormone health affects fertility, metabolism, and mental health for both men and women.  The core question is simple: if hormones run your body, how much influence do you have over them?  Alongside ZOE’s head nutritionist, Dr Federica Amati, Helen explores the links between hormones and fatigue, anxiety, weight gain, fertility, and metabolic health. The episode covers thyroid health, chronic pain, sperm health, and why gut hormones play a central role in appetite and weight regulation. We also examine why some female-specific conditions remain misunderstood or undiagnosed, and how better data may help change that. Most importantly, this episode focuses on what you can do to take back control. With emerging science suggesting that diet plays a key role in hormone regulation, you’ll hear how fibre, plant diversity, healthy fats, and key micronutrients support gut hormone production and fertility. You’ll also learn why changes made over three months may meaningfully influence fertility, and why conception is always a shared responsibility.

How to drink alcohol without destroying your health | Prof. David Nutt

Dry January often raises big questions: how much alcohol is actually safe, and do you need to stop drinking altogether to protect your health? In this episode, world-leading alcohol expert Professor David Nutt explains why alcohol ranks as one of the most harmful drugs to society, how even “normal” drinking can affect your health, and what the science really says about cutting back without giving it up completely. David, a neuropsychopharmacologist and former UK government drug adviser, explains why alcohol was ranked the most harmful drug overall in a landmark comparison of 20 drugs, how harm rises sharply as drinking increases, and unpacks common beliefs like red wine being “good for you”. The conversation also covers the social benefits of alcohol and why the goal isn’t necessarily to stop drinking, but to drink with awareness. If you drink at all - whether it’s a glass most nights or more on weekends - this episode helps you understand where the real risks begin, and how to make alcohol work for you, not against you. And for listeners using dry January as a reset, David shares practical, science-based advice on how to cut down safely and sustainably. If you’re pausing and reflecting this dry January, what might change when you start drinking again? And which habits are worth leaving behind for good?
