Would you like to stay healthy until you're 100? For most of us, the answer is, of course, yes. But why do some people live longer, and is it achievable? In this episode, best-selling author and longevity expert Dan Buettner, explores what decades of studying the people who live the longest reveal about health and lifespan. Instead of chasing hacks, the science suggests that a longer life is shaped by everyday food, social habits, and the places people live. We’ll look at practical habits seen across the world’s blue zones, rare global hotspots where celebrating your 100th birthday is common. Rather than relying on willpower, Dan explains why changing your routine and environment may be easier and more effective. By the end of the episode, you’ll have some simple tips to help you start your day like you live in a Blue Zone - and increase your chances of living healthily to 100.

Inside each of us lives a bustling community of microbes; tiny organisms that outnumber our human cells. They’re there from the very moment we’re born, shaping our immune system and influencing our long-term health. The science of the microbiome is evolving rapidly, but one thing is clear: We need to take care of these microbes so that they can take care of us. Today, I’m joined by Dr. Suzanne Devkota and Tim Spector to explore how our gut bacteria protect us from disease and what we can do to strengthen this vital partnership. 🌱 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 by our ZOE Scientists The Food For Life Cookbook Every Body Should Know This by Dr Federica Amati Food For Life by Prof. Tim Spector Ferment by Prof. Tim Spector Free resources from ZOE Live Healthier: Top 10 Tips From ZOE Science & Nutrition Gut Guide - For a Healthier Microbiome in Weeks  Better Breakfast Guide Have feedback or a topic you'd like us to cover?

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?

Change is difficult. Our routines can feel locked in, our habits on autopilot, and the idea of a major lifestyle overhaul can seem impossible.  However, Rich Roll is living proof that this isn’t the case. Once struggling with addiction and poor health, he transformed his diet, rebuilt his body, and completely rewrote his future. In today’s conversation, Tim Spector and Rich Roll discuss why midlife is a crucial turning point for health, what happens to your microbiome when you change your diet, and why it’s never too late to make a dramatic shift. 🌱 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 Every Body Should Know This by Dr Federica Amati Food For Life by Prof. Tim Spector Ferment by Prof. Tim Spector Free resources from ZOE: Live Healthier: Top 10 Tips From ZOE Science & Nutrition Gut Guide - For a Healthier Microbiome in Weeks  Better Breakfast Guide Have feedback or a topic you'd like us to cover?

What really happens when you stop dieting and start eating healthy? In this episode, we hear from two real people who spent years trying to “do the right thing” with food and still felt stuck.  Today, we’re joined by Becky and Mark, two ZOE members sharing their personal journeys. Each of them has spent the past two years consistently applying ZOE nutrition principles. Instead of relying on rules or restrictions, they embarked on a science-led journey with ZOE, focused on understanding their bodies. The results? Truly remarkable - ZOE became such an important part of their lives that, alongside 18,000 other members of our community, they became ZOE owners through our crowdfunding. So what changed, and did it last? Alongside Professors Tim Spector and Sarah Berry, we explore how Becky and Mark stay motivated and on track, the lessons they have learned, and the strategies they have used to feel more in control and more confident in their everyday choices. As well as some unexpected shifts along the way. It’s a conversation about long-term change, not quick fixes, and you’ll leave it with real-life examples of how to make healthy eating a part of your everyday life. If healthy eating wasn’t about willpower or perfection, what small change would you start with? And what would help you take that first step this week?

We often hear people talk about metabolism - whether it’s fast, slow, strong, or sluggish. It’s one of those health buzzwords that’s often said, but rarely understood.

In this episode, Shawn Stevenson and Tim Spector cut through the confusion. Together, they’ll explain what metabolism actually is, and empower you to take control of yours. 🌱 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 by our ZOE Scientists The Food For Life Cookbook Every Body Should Know This by Dr Federica Amati Food For Life by Prof. Tim Spector Ferment by Prof. Tim Spector Free resources from ZOE Live Healthier: Top 10 Tips From ZOE Science & Nutrition Gut Guide - For a Healthier Microbiome in Weeks  Better Breakfast Guide Have feedback or a topic you'd like us to cover?

Calories. They’ve been at the heart of dieting advice for decades. Eat fewer, burn more, lose weight. simple, right? Except it’s not that simple. Calories only tell us a fraction of the story. To really understand what's going on, we need to take a step back and look at the bigger picture. Helping us take this step is biologist Giles Yeo. He’ll explain why obsessing over the numbers doesn’t work, and how we can change the way we approach weight loss. 🌱 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 by our ZOE Scientists The Food For Life Cookbook Every Body Should Know This by Dr Federica Amati Food For Life by Prof. Tim Spector Ferment by Prof. Tim Spector Free resources from ZOE Live Healthier: Top 10 Tips From ZOE Science & Nutrition Gut Guide - For a Healthier Microbiome in Weeks  Better Breakfast Guide Have feedback or a topic you'd like us to cover?
