244: The Metabolic Root of Depression, Anxiety, & Mental Illness - Dr. Lori Calabrese

In this transformative episode of Stay Off My Operating Table, Dr. Philip Ovedia sits down with Dr. Lori Calabrese, a pioneering psychiatrist in the emerging field of metabolic psychiatry. Dr. Calabrese shares her journey from a traditional psychiatric practice to becoming a trailblazer in using ketogenic metabolic therapy to treat severe mental health conditions. Her pivotal moment came when a patient with 15 years of chronic anorexia nervosa achieved full remission after starting a ketogenic diet—sparking a decade-long exploration into how metabolic health underpins mental wellness. She details case series showing complete remission of major depression, generalized anxiety, and ADHD within 12 weeks, alongside dramatic improvements in metabolic markers and even resolution of ulcerative colitis. The conversation reframes mental illness not as isolated brain chemistry issues, but as manifestations of systemic metabolic dysfunction, particularly mitochondrial health and insulin resistance. Dr. Calabrese argues that stabilizing cellular energy through diet and lifestyle—rather than relying solely on pharmaceuticals—empowers patients with lasting resilience. She contrasts this with GLP-1 medications, which she views as temporary fixes lacking the deep cellular benefits of true ketosis, such as mitophagy and autophagy. The episode underscores a paradigm shift: mental and physical health are not separate, but deeply interconnected through metabolic pathways, and true healing requires a holistic, patient-centered approach that integrates nutrition, circadian rhythm, and mind-body practices.
