In this episode of The Evolution of Medicine, host James Maskell interviews Dr. Ryan Arnold, founder of Clava Health and a former emergency and critical care physician who transitioned into functional medicine.

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.

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 event that reshapes the brain, nervous system, immune function, and digestive health.

About the Guest:

Debbie Silber, PhD is the founder of the Post Betrayal Transformation Institute and creator of the PBT® (Post-Betrayal Transformation) Certification Program. After experiencing multiple betrayals herself, she completed a PhD study on how betrayal impacts health, work, and relationships. Her research identified Post-Betrayal Syndrome and the 5 stages of healing. She is the author of Unstuck and works with both individuals and healthcare practitioners worldwide.

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 Physician–Dietitian–Health Coach triad to ensure sustainable outcomes.

The episode challenges practitioners to stay "agnostic about the agonist" and instead focus on metabolic repair, patient education, and structured team-based care.

About the Guest:

Ashley Koff, RD is a registered dietitian and functional nutrition expert focused on metabolic health, personalized nutrition, and hormone signaling. She is the author of Your Best Shot and advocates for a "Weight Health" approach that integrates assessment, repair, and team-based implementation.

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, team-based care, defined outcomes, and recurring membership structures.

This episode also launches a new initiative designed to help clinics operationalize that shift.

James Maskell is a healthcare entrepreneur and founder of The Evolution of Medicine. For over 20 years, he has worked to scale functional medicine through community-driven models, group visits, and practitioner infrastructure. His work focuses on moving medicine upstream—toward prevention, lifestyle intervention, and systems-based care.

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 emerging research on physiological resilience, Whitten explains why building "reserve capacity" may be the most powerful strategy for long-term brain health.

Ari Whitten is a health educator, researcher, and expert in energy metabolism and human performance. His work focuses on evolutionary health, mitochondrial function, and physiological resilience as foundations for preventing chronic disease. Ari is widely known for translating complex research into actionable lifestyle strategies that help people build robust health in the modern world.

In this episode of The Evolution of Medicine podcast, host James Maskell speaks with Dr. Matthew Bernstein about the emerging field of metabolic psychiatry. They explore how addressing metabolic health—particularly through ketogenic diets—can treat and, in some cases, reverse serious mental health conditions that conventional psychiatric medications often fail to resolve.

Through personal stories, clinical insights, and a forward-looking discussion on research and policy, the episode challenges the long-standing "chemical imbalance" narrative and reframes mental illness as a systemic, energy-based disorder rooted in metabolic dysfunction.

James Maskell interviews Dr. Matthew Bernstein on metabolic psychiatry, ketogenic diets, and the future of mental health care, exploring how metabolic health can reverse depression, bipolar disorder, and psychosis on The Evolution of Medicine Podcast.

Dr. Matthew Bernstein is a psychiatrist and pioneer in metabolic psychiatry. After a family health crisis involving his sons' diagnosis of PANS (Pediatric Acute Neuropsychiatric Syndrome), he shifted away from medication-centric psychiatry toward addressing root causes such as metabolic dysfunction, inflammation, and immune dysregulation. He is the founder of Accord, an immersive metabolic health program near Boston.

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 burden, immune stress, and the cumulative impact of modern life on developing nervous systems. As the cultural conversation shifted and the term "Outsmarting Autism" began to feel limiting, Patti revisited the work with fresh eyes. The result is Total Load Theory – a reframing grounded in functional medicine's understanding of total allostatic load: the combined environmental, biochemical, infectious, emotional, and physiological burdens our children are carrying.

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 topic for the next decade.
