The Lancet Voice

Gavin welcomes Walter Willett, Shakuntala Thilsted and Johan Rockström to discuss the second EAT-Lancet Commission report. The co-chairs explain the significant updates since the inaugural 2019 commission, including new global evidence on nutrition, advances in food systems modelling, and a greater focus on equity and justice. The panel addresses the health and environmental impacts of dietary choices, the urgent need for systemic transformation, and the practical challenges of achieving sustainable and healthy food for all. Walter, Shakuntala, and Johan provide an authoritative overview of why food justice, planetary boundaries, and community engagement are central to the future of both global health and the environment.Read the Commission here:https://www.thelancet.com/commissions-do/2025-EAT?dgcid=buzzsprout_tlv_podcast_lanceteat25_lancetSend us your feedback!Read all of our content at https://www.thelancet.com/?dgcid=buzzsprout_tlv_podcast_generic_lancetCheck out all the podcasts from The Lancet Group:https://www.thelancet.com/multimedia/podcasts?dgcid=buzzsprout_tlv_podcast_generic_lancetContinue this conversation on social!Follow us today at...https://thelancet.bsky.social/https://instagram.com/thelancetgrouphttps://facebook.com/thelancetmedicaljournalhttps://linkedIn.com/company/the-lancethttps://youtube.com/thelancettv

Scientific research has traditionally treated the male body as the default, resulting in health inequity and poor outcomes for women in a world not designed for them. The Sex and Gender Equity in Research (SAGER) guidelines are an attempt to make sure research is designed for everyone, and that the outcomes better serve everyone.Editor-in-chief of The Lancet Haematology Lan-Lan Smith and editor-in-chief of The Lancet Regional Health Americas Taissa Vila join Gavin to discuss how the history of scientific research led us to this point, what the SAGER guidelines are, and how science is addressing the research gap.Send us your feedback!Read all of our content at https://www.thelancet.com/?dgcid=buzzsprout_tlv_podcast_generic_lancetCheck out all the podcasts from The Lancet Group:https://www.thelancet.com/multimedia/podcasts?dgcid=buzzsprout_tlv_podcast_generic_lancetContinue this conversation on social!Follow us today at...https://thelancet.bsky.social/https://instagram.com/thelancetgrouphttps://facebook.com/thelancetmedicaljournalhttps://linkedIn.com/company/the-lancethttps://youtube.com/thelancettv

Gavin, Richard, and Jessamy enter the studio once more for a Lancet Voice chat.

Where did the 10,000 steps recommendation come from? Why has it proven so stubborn? What's the science behind the new recommendations? How strong is the evidence?Professor Melody Ding joins Gavin to talk about her new systematic review published in The Lancet Public Health, examining the relationship between step counts and health outcomes. We also explore the challenges of measuring physical activity, the importance of inclusive research, and the role of environmental and policy interventions in promoting population health.Read the article from The Lancet Public Health here:https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667(25)00164-1/fulltext?dgcid=buzzsprout_tlv_podcast_August_25_lanpubSend us your feedback!Read all of our content at https://www.thelancet.com/?dgcid=buzzsprout_tlv_podcast_generic_lancetCheck out all the podcasts from The Lancet Group:https://www.thelancet.com/multimedia/podcasts?dgcid=buzzsprout_tlv_podcast_generic_lancetContinue this conversation on social!Follow us today at...https://thelancet.bsky.social/https://instagram.com/thelancetgrouphttps://facebook.com/thelancetmedicaljournalhttps://linkedIn.com/company/the-lancethttps://youtube.com/thelancettv

It’s no exaggeration to say that the past decade has revolutionized how we think about and treat obesity. Drugs like semaglutide (Wegovy) and tirzepatide (Zepbound) have dominated headlines, enabling significant weight loss at speeds once considered unthinkable. The market for innovative weight loss medications is booming, with pharmaceutical companies investing heavily in hopes of developing the next blockbuster drug.However, amid this race for market dominance, many experts are questioning whether the amount of weight loss alone is the best measure of these drugs’ usefulness. How can the next generation of obesity treatments meaningfully improve upon the powerful options already available?Joining The Lancet editors Callam Davidson and Miriam Sabin to discuss this question is Professor Steven Heymsfield from the Pennington Biomedical Research Center. This wide-ranging conversation covers exciting pharmaceutical advances and limitations of these treatments, including the significant disparities in access, and why these breakthroughs may have broader societal implications.Send us your feedback!Read all of our content at https://www.thelancet.com/?dgcid=buzzsprout_tlv_podcast_generic_lancetCheck out all the podcasts from The Lancet Group:https://www.thelancet.com/multimedia/podcasts?dgcid=buzzsprout_tlv_podcast_generic_lancetContinue this conversation on social!Follow us today at...https://thelancet.bsky.social/https://instagram.com/thelancetgrouphttps://facebook.com/thelancetmedicaljournalhttps://linkedIn.com/company/the-lancethttps://youtube.com/thelancettv

Andrea Winkler, a top neurologist at the Technical University of Munich and the University of Oslo, teams up with John Amuasi, head of Global Health at Kwame Nkrumah University in Ghana, to explore the One Health framework. They discuss how our health is intertwined with that of animals and the environment. Topics include tackling climate change and antimicrobial resistance, as well as redefining global health financing to prioritize One Health initiatives. Their insights shed light on the critical need for collaboration and innovative policies to improve health outcomes globally.

Professor Adam Kucharski joins Gavin & Jessamy to discuss the intersection of mathematics, epidemiology, and truth, off the back of his new book, Proof. How do we generate scientific knowledge? How can we communicate uncertainty? What is the impact of social media and artificial intelligence on public trust in science?Adam also tells us about the importance of public engagement, the nuances of misinformation, the importance of transparency in policy, the future of scientific communications, the need for adaptable definitions of proof, and the value of pragmatic, transparent approaches to decision-making in health and science.Send us your feedback!Read all of our content at https://www.thelancet.com/?dgcid=buzzsprout_tlv_podcast_generic_lancetCheck out all the podcasts from The Lancet Group:https://www.thelancet.com/multimedia/podcasts?dgcid=buzzsprout_tlv_podcast_generic_lancetContinue this conversation on social!Follow us today at...https://thelancet.bsky.social/https://instagram.com/thelancetgrouphttps://facebook.com/thelancetmedicaljournalhttps://linkedIn.com/company/the-lancethttps://youtube.com/thelancettv

Gavin, Richard, and Jessamy return to the studio to discuss some publications that caught their eye this month, and in doing so set themselves the lofty goal of examining how meaning, purpose, optimism, and social context shape our understanding of health beyond traditional clinical measures. We also ponder the future of research and higher education in the face of funding challenges in both the US and the UK.Articles mentioned in this episode:The Global Flourishing Study: https://www.nature.com/articles/s44220-025-00423-5The second Lancet Commission on adolescent health and wellbeing: https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(25)00503-3/fulltext?dgcid=buzzsprout_tlv_podcast_May_25_lancetStanding up for gender justice: https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(25)00679-8/fulltext?dgcid=buzzsprout_tlv_podcast_May_25_lancetHow the United States became a science superpower: https://www.nature.com/articles/d41586-025-01146-4Universities grip financial crisis – but at what cost to the nation?: https://www.universitiesuk.ac.uk/what-we-do/creating-voice-our-members/media-releases/universities-grip-financial-crisis-whatSend us your feedback!Read all of our content at https://www.thelancet.com/?dgcid=buzzsprout_tlv_podcast_generic_lancetCheck out all the podcasts from The Lancet Group:https://www.thelancet.com/multimedia/podcasts?dgcid=buzzsprout_tlv_podcast_generic_lancetContinue this conversation on social!Follow us today at...https://thelancet.bsky.social/https://instagram.com/thelancetgrouphttps://facebook.com/thelancetmedicaljournalhttps://linkedIn.com/company/the-lancethttps://youtube.com/thelancettv
