Today we’re talking about intermittent fasting.
This form of time-restricted eating has been gaining significant popularity, with many people reporting positive effects after incorporating it into their daily routines. However, here at ZOE, we want to know what the science says about intermittent fasting.
Is it the real deal? Or just another fad?
I’m joined by Tim Spector and Gin Stephens to break down what intermittent fasting is, how it affects our bodies, and whether the scientific evidence supports it.

Recap: What the science says about intermittent fasting | Gin Stephens

Are you navigating the twists and turns of perimenopause and beyond? Traditional exercise advice often misses the mark for women in this phase, mostly because its source is research focused on men. 
In today’s episode, we're joined by the acclaimed Dr. Stacy Sims, a leading expert on women's exercise science. Stacy delves into how menopause affects our exercise responses, and she offers strategies to adapt your fitness routine for optimal health during and after menopause.
Ready to transform your approach to health and fitness? Tune in for expert insights and actionable tips.
Dr. Stacy Sims is an exercise physiologist and nutrition scientist who researches exercise performance and nutrition with a focus on women’s health and performance. She holds a Ph.D. in exercise physiology and sports nutrition from the University of Otago, and she did a postdoc at Stanford, where she remains an adjunct faculty member. Stacy is also a research associate at the AUT Sports Performance Research Institute New Zealand.

Fitness routines for menopause with Dr. Stacy Sims - exercise for every stage

Inflammation is a complicated topic. Short-term inflammation plays an essential role in fighting infections and healing injuries. But too much inflammation can be a catalyst for chronic ailments, like heart disease, type 2 diabetes, autoimmune disorders, rheumatoid arthritis, and obesity.
What we eat can influence our inflammatory responses and contribute to chronic, low-grade inflammation.
In today’s episode, Prof. Philip Calder helps us understand the science behind inflammation, how it impacts our health and what food has to do with it.
Philip is head of the School of Human Development and Health, as well as a Professor of Nutritional Immunology, in the Faculty of Medicine at the University of Southampton. He’s also an internationally recognised researcher on the metabolism and functionality of fatty acids. His work focuses on the roles of omega-3 fatty acids and the influence of diet and nutrients on immune and inflammatory responses.

Recap: Reduce inflammation with a sprinkle of spices | Kanchan Koya

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.

Let’s take a look back at our best episodes of 2024. We had an incredible lineup of guests this year who shared a huge range of actionable tips on improving your nutrition and gut health. 
A lot of what we learned might surprise you. Like the beverage you’re probably drinking every day that we thought was bad for us? Turns out it can actually be super beneficial. Or that what counts as a plant is actually so much more than just fruit and veg. Not forgetting the topic we’ve shattered the taboo on - which made our celebrity guest emotional.

Recap: Simple steps to prevent dementia | Dr Claire Steves

Our gut helps fight disease. It processes energy for us and boosts our mood. So, having a healthy gut is extremely important – but there’s still a lot we don’t know. 
Gut biome tests are a new, exciting technology, but are they the be-all and end-all for dietary decision-making? And are there simpler ways — and tastier ways, perhaps — to tell what’s happening inside our bodies?
In today’s short episode of ZOE Science & Nutrition, Jonathan and Dr. Will ask: What are the signs of an unhealthy gut? And how can we improve our gut health?
