Introducing Series Two of Big Ideas in Eating Disorders:
The Podcast
This series of podcasts accompanies the publication of Big Ideas in Eating Disorders: Accelerating Research to Transform Policy and Practice, which we co-edited. The book brings together many of the field’s boldest thinkers to imagine a better future for eating disorder research, prevention, treatment, and recovery. In this podcast, Kathy, as host, sits down with contributing authors to explore the ideas behind their chapter and the personal and professional journeys that inspired them.

In the first series of this podcast, leaders in our field share discoveries and defining moments from their careers. Those conversations are centered on big ideas that capture the history of our field in stories, debates, and insights that rarely find their way into academic publications or conference presentations.
Series Two looks to the future. Guests elaborate on the bold ideas they contributed to our book. We explore not only the science behind each chapter, but also the questions that have driven our guests’ work, the experiences that shaped their thinking, and the breakthroughs they believe could fundamentally change the field. These conversations offer an insider’s view of how big ideas are born, tested, refined, and ultimately translated into better science, better policy, and better care.
Whether you are a researcher, clinician, policymaker, advocate, student, or someone with lived experience, we invite you to read the book, listen to the conversations, and imagine what is possible.
The future of eating disorders will not be transformed by incremental steps. It will be transformed by big ideas that are bold enough to challenge assumptions, accelerate discovery, and change lives.

Big Ideas in Eating Disorders
Praise for the Book
“Led by pioneers of innovation, Big Ideas in Eating Disorders delivers on its promise to give bold answers to tough questions. Companion podcasts with clinicians, scientists, and individuals with lived experiences bring personal stories to life—laying the critical foundation for major breakthroughs that will help us to eradicate eating disorders.”
—Pamela K. Keel, PhD
Robert O. Lawton Distinguished Professor, Department of Psychology, Florida State University; Fellow, American Psychological Association
“No room for comfort with worn-out ideas here. This book engages readers in a bold, forward-looking experiment. Each of the best thinkers in the eating-disorders world envisions a ‘Big Idea,’ explaining why it’s needed, how to test it, and how to make it happen. Whether you are a clinician, researcher, educator, or advocate, this book will widen your perspectives on eating-disorder classification, etiology, care, and policy in ways you have not considered before.”
—Howard Steiger, PhD
Emeritus Professor, Department of Psychiatry, McGill University; Former Head, Eating Disorders Continuum, Douglas Mental Health University Institute, Montreal
“Finally, a brand new look at eating disorders with an eye to moving the field quickly toward meaningful solutions. Drs. Weissman and Pike have assembled an impressive group of scholars who reveal their Big Ideas to improve identification, understanding, treatment, and clinical outcome for the millions of individuals worldwide affected by these complex conditions.”

Suzanne Crosby Murphy Professor of Psychiatry, Columbia University Irving Medical Center; Professor of Clinical Psychiatry, Weill Cornell Medicine; Director, Center for Eating Disorders, New York–Presbyterian Hospital
“This book is exactly what the field needs right now. It offers inspiration and exposure to innovative thinking, as well as new and bold ideas emerging from many years of research, clinical work, personal experience with eating disorders, and reflection. The editors, world-leading researchers in the field, have truly succeeded in bringing together contributors who share ideas, visions, and reflections that feel like a feast for the mind.”

Phillipa Hay MD, DPhil, is Chair of Mental Health, Translational Health Research Institute, Western Sydney University, Penrith South, New South Wales and the Director of Mental Health Research at Southwestern Sydney Local Health District. Dr. Hay is an academic psychiatrist who is recognised internationally for her expertise in reducing the personal and public health burden of eating disorders and obesity.
Deborah Mitchison, PhD is Associate Professor in Psychology at the Graduate School of Health at the University of Technology Sydney. Professor Mitchison also holds adjunct appointments at Western Sydney University and Macquarie University.
Drs. Hay and Mitchison’s chapter in Big Ideas In Eating Disorders poses a big and provocative idea: What if we completely reimagined how the field classifies and diagnoses eating disorders? They argue that the current diagnostic frameworks are confusing and limited in practice, and they strongly advocate that the field will be better served by understanding the defining features of an individual’s eating disorder and the unique constellation of symptoms as experienced by the individual. In this podcast, Dr. Hay elaborates on these core ideas and what they would mean in real-world practice.

Today we have the good fortune to hear from Dr. Kelly Klump whose contributions to the field of eating disorders are indeed invaluable. Inspired by one of her early mentors, Professor Gloria Leon, Dr. Klump has embarked on a journey of groundbreaking research that reshapes our understanding of the complex interplay between genetics, hormones, and environmental factors in the development of eating disorders. Dr. Klump’s exploration of gonadal hormones, including estrogen, progesterone, and testosterone, is steadily uncovering the relationship of hormonal fluctuations, particularly during puberty, to the onset and expression of eating disorders. Translating these findings to clinical practice has the potential to inform more effective prevention strategies and personalized interventions for individuals at risk of developing eating disorders.
