We all know that eating well matters; but what does that actually mean for you, specifically? Low-fat, low-carb, mediterranean, keto, intermittent fasting… What if the reason no single diet works for everyone is because no single diet should?In this episode, Greg and Charlie sit down with Dr. Lucia Aronica, an epigenetics and nutrigenomics scientist at Stanford University School of Medicine, who has contributed to the DIETFITS study, one of the best-known trials in the field of personalised nutrition. Lucia will break down what factors shape personalisation, and what the research really shows. We discuss the findings of the DIETFITS study, explain how individual responses vary, and break down what variables really matter for a healthy diet. We then zoom out to ask the bigger question: is there actually compelling evidence that a personalised nutrition plan beats a well-designed, healthy, generic one?From there, we move into our practice segment, where Lucia shares what this all means day-to-day. We cover:The healthy eating principles that apply to all of us, whatever our goals (21:41)Why testing insulin is crucial (25:06)Why pleasure is the key to adopt long-lasting healthy eating habits (29:21)Finally, in the experience section, we pick up on your questions. From the future of DNA-based nutrition to the truth about keto and your microbiome, meal timing, insulin spikes, and whether that daily tablespoon of olive oil is as good as people say, Lucia gives her take on some of the most common (and most debated) questions in nutrition today.Personalised nutrition is a genuinely exciting scientific territory, but at times, it can be overhyped. This episode helps you figure out what the evidence actually supports, and what practical steps you can take right now. To explore further:Lucia Aronica - WebsiteLucia Aronica - Stanford ProfileLucia’s Clinical Epinutrition CourseThe Standford DIETFITS StudyGreg Potter - WebsiteGreg Potter - InstagramThriva - WebsiteIf you’d like to send us your health questions for future episodes, you can email us a voice note, or simply write in with your question at [email protected] Thriva:Thriva is a proactive health platform built for the modern age.
