How many different plants do you eat a week? Gut health expert Tim Spector joins Liz to share how we can improve our diet and gut microbiome to overhaul our health with his six key principles.   In this episode, Tim - who is a Professor of Epidemiology at King's College, London - reveals how a mini-stroke served as a much-needed wake-up call to pivot his attitude to food and nutrition.   Tim and Liz chat through whether you can tell how healthy you are by looking at your gut microbiome diversity, why it might be time to scrap calorie counting, and the magic number of plants we should be eating every week.   They also cover how to get more fermented foods into your diet, and Tim shares his thoughts on longer periods of fasting, following Liz's recent stint at a well-known fasting clinic.   Links mentioned in the episode: Purchase the Food for Life CookbookFollow Tim Spector on InstagramVisit the Zoe websitePurchase A Better Second Half by Liz EarleEmail us your questions at [email protected] Hosted on Acast.
