Series 2: Episode 1 - A Re-Imagining of the Diagnostic Spectrum of Eating Disorders with Dr. Phillipa Hay
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.

Dr. Kelly Klump
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.

Dr. Anne Becker
Today’s episode takes us on a global journey with Dr. Anne Becker, Maude and Lillian Presley Professor of Global Health and Social Medicine at Harvard Medical School. Although Anne never became the meteorologist she imagined in her youth, as a psychiatrist and anthropologist, she traveled far from home to launch pioneering work in Fiji focused on how culture contributes to shaping the meaning of body image and risk for eating disorders. In this episode, Anne shares how she got to Fiji, the surprising conversations, and the evolving meaning of weight in Fijian communities at different points in time. Anne shares the serendipitous circumstances that enabled her to map the impact of the arrival of American television on triggering eating disorder symptoms and rising body shape and weight concerns. Dr. Becker’s keen intellect and her delight in discovery is riveting and contagious as she shares her pioneering work, which is foundational for anyone who wants to understand culture and eating disorders.

Dr. Joel Yager
This marks the beginning of a six-part series centered around the proposed diagnosis of "Terminal Anorexia Nervosa." In this inaugural episode, I talk with Dr. Joel Yager, Professor Emeritus of Psychiatry at the University of Colorado School of Medicine. Dr. Yager, alongside co-authors Dr. Jennifer Guadiani and Alyssa Bogetz, an individual with Anorexia Nervosa who passed away before the article's publication, proposed the criteria for “Terminal Anorexia Nervosa” in the paper linked below. With decades of experience in the eating disorder field, Dr. Yager served as the Director of the Eating Disorders Clinic at UCLA from 1981 to 1988. His contributions have earned him numerous awards, including the Lifetime Achievement Award from the National Eating Disorders Association, the Special Presidential Commendation, and the Distinguished Service Award from the American Psychiatric Association, along with a Lifetime Achievement Award from the Colorado Psychiatric Society. Drawing from his extensive expertise, Dr. Yager articulates why he believes it is crucial for the field to grapple with and refine the proposed diagnosis of "Terminal Anorexia Nervosa." This proposal has ignited a robust conversation and debate among a diverse range of stakeholders. In the upcoming episodes, we will hear perspectives from American and European colleagues, a biomedical ethicist, and individuals with lived experiences - all sharing their varied views on this highly controversial topic.

Dr. Bryn Austin
In this episode we hear from Dr. Bryn Austin, award-winning researcher, teacher, and mentor and Founding Director of the Strategic Training Initiative for the Prevention of Eating Disorders: A Public Health Incubator (STRIPED). Dr. Austin is Professor of Pediatrics at Harvard Medical School and Professor of Social and Behavioral Sciences at the Harvard T.H. Chan School of Public Health. In this episode, she urges all of us in the field to think about risk for eating disorders from a public health and social justice perspective. She has documented that the economic cost of eating disorders is close to 65 billion USD annually - on par with severe mental illnesses like schizophrenia. She has also led research that demonstrates that prevention interventions are cost-effective. She urges scientists to get involved with policy and democracy – to engage with the world to change the world. Specifically, she makes the case that we need to pursue policy strategies to combat toxic environmental factors like social media, weight discrimination, and predatory products (like diet pills) to raise awareness and make systems changes that reduce the risk for eating disorders at a population level. After listening to Dr. Austin, your understanding of eating disorders risk and prevention will be forever transformed.
