Betrayal and the Brain
Evolution of Medicine Podcast
In this episode of The Evolution of Medicine, host James Maskell interviews Debbie Silber, PhD, founder of the Post Betrayal Transformation Institute and author of Unstuck. The conversation explores why betrayal is a distinct and often overlooked root cause of chronic physical and mental health conditions. Dr. Silber shares her groundbreaking research on Post-Betrayal Syndrome (PBS), the predictable 5 stages of healing, and why so many patients remain “stuck” despite functional or conventional care. This episode reframes betrayal not as an emotional inconvenience—but as a physiological...

Your Best Shot: Holistic Approach to GLP-1
Evolution of Medicine Podcast
In this episode of The Evolution of Medicine, host James Maskell interviews registered dietitian Ashley Koff about her new book Your Best Shot. The conversation explores the seismic impact of GLP-1 agonists like Ozempic and Wegovy—and how functional medicine can pivot from a “weight loss” mindset to a “weight health” approach. Koff reframes these medications not as magic bullets, but as biosimilar hormone replacement tools that “switch on” receptor sites—without repairing the underlying ecosystem. She outlines a five-part Weight Health Hormone assessment and introduces a...

From Artisan to Infrastructure
Evolution of Medicine Podcast
In this episode of The Evolution of Medicine, host James Maskell outlines a pivotal shift for functional medicine practitioners. He argues that the era of the “artisan” solo practitioner is ending—and that survival in 2026 and beyond requires building scalable clinical infrastructure. Maskell explains how AI-powered platforms, venture-backed telehealth companies, and direct-to-consumer lab brands are redefining patient expectations around speed, convenience, and affordability. To compete, functional medicine clinics must evolve into “full stack” models—combining objective data,...

An Evolutionary Perspective on Brain Diseases
Evolution of Medicine Podcast
In this episode of The Evolution of Medicine podcast, host James Maskell speaks with health educator and researcher Ari Whitten about why modern medicine has failed to meaningfully prevent or reverse Alzheimer’s disease—and how an evolutionary and lifestyle-based framework offers a far more effective path forward. The conversation reframes Alzheimer’s not as an inevitable consequence of aging, but as a disease of evolutionary mismatch—the result of modern lifestyles that conflict with our ancient biological design. Drawing on anthropological data, long-term population studies, and...

Jan 2026 Wrap: From Food Pyramid to Electrosmog
Evolution of Medicine Podcast
In this solo episode of The Evolution of Medicine, host James Maskell explores emerging conversations in healthcare, focusing on low-level toxicity, electromagnetic fields (EMFs), and practical ways clinicians can support patients in reversing chronic illness. The episode highlights personal experiences, clinical observations, and actionable strategies for reducing “electrosmog” or electromagnetic fog exposure in everyday life, alongside broader insights into optimizing environmental health for longevity and functional medicine. James Maskell explores EMFs, low-level toxicity, and...

Total Load Theory (Featuring: Patricia S. Lemer)
Evolution of Medicine Podcast
This week on the podcast, we welcome Patti Lemer who last year gave me the opportunity to do something I’ve never done before, write the foreword to her new book. Patti is an OG in the autism space and a true pioneer in understanding the environmental drivers impacting children’s health. The book is Total Load Theory. Many people know Patti from her earlier work, Outsmarting Autism, which drew from decades of hands-on experience working with kids on the spectrum. Long before environmental illness entered mainstream conversation, Patti was already mapping the terrain, looking at toxic...

2026 | A Call to the Most Important Mission of Our Lifetime
Evolution of Medicine Podcast
To start the year, I would love it if you could find 10 minutes today to read what I believe is the most important blog I’ve written. It contextualizes the importance of both my first book, The Evolution of Medicine and my second, The Community Cure, to now what I believe is the most important moment and mission of our time… I also reviewed the incredible recent Lyme Disease Roundtable that probably should have been 30 years ago, but it is exciting to see something come into light that has been hidden to health seekers and clinicians alike. It sets up our community for leadership on this...

The conversation explores Dr. Arnold’s journey from hospital-based medicine to building a scalable functional medicine clinic focused on root-cause care, longevity, and brain health. He shares how frustration with traditional disease-focused medicine pushed him to pursue functional medicine training and eventually launch a cash-based practice.
Dr. Arnold explains why brain health is emerging as the central pillar of longevity medicine and how cognitive decline can often be reversed through comprehensive functional medicine protocols that address metabolism, sleep, inflammation, and lifestyle factors.
The episode also dives into the importance of program-based care models, multidisciplinary teams, practitioner collaboration, and how new technologies like relational AI can help clinics scale patient education and engagement.
About the Guest:
Dr. Ryan Arnold, MD is the founder of Clava Health, a functional medicine clinic focused on longevity, metabolic health, and cognitive optimization. Originally trained in emergency and critical care medicine, Dr. Arnold transitioned to functional medicine after recognizing the limitations of traditional disease management.
He now leads a program-based practice that integrates personalized medicine, lifestyle interventions, multidisciplinary care teams, and emerging technologies to help patients prevent and reverse chronic disease—particularly cognitive decline.
