The Sleep Regimen

Eric Pifer, MD is a physician, entrepreneur, and founder of the LifeLab Protocol, a science-driven framework designed to restore metabolic health, resilience, and long-term vitality. With more than two decades of clinical experience, Dr. Pifer specializes in metabolic medicine, lifestyle optimization, and the prevention of chronic disease through evidence-based, non-pharmacologic strategies.

Dr. Pifer’s work focuses on the interconnected pillars of health that modern medicine often treats in isolation: sleep, nutrition, movement, stress, and metabolic function. He is particularly known for translating complex physiology into practical, actionable programs that patients can implement in real life. His approach emphasizes root-cause repair rather than symptom suppression, integrating modern clinical science with evolutionary biology, behavioral psychology, and longitudinal patient data.

After years practicing within large healthcare systems, Dr. Pifer founded LifeLab to pursue a more thoughtful, patient-centered model of care. LifeLab combines precision diagnostics, structured protocols, and education to help individuals reverse insulin resistance, improve sleep quality, restore energy, and extend healthspan. The LifeLab Protocol serves as the foundation for a growing series of books, programs, and live experiences focused on sustainable, lifelong health.

Dr. Pifer is the author of The LifeLab Protocol: A One-Year Pathway to Better Health and subsequent focused volumes addressing sleep, metabolism, nutrition, and performance. His writing reflects both clinical rigor and deep respect for the lived experience of patients who have struggled with fatigue, weight gain, poor sleep, and chronic inflammation despite “doing everything right.”

In addition to his clinical and writing work, Dr. Pifer teaches, lectures, and develops immersive health programs for motivated individuals seeking a higher level of insight and accountability. His work is grounded in scientific skepticism, intellectual honesty, and the belief that meaningful health improvement requires clarity, patience, and disciplined habit change rather than quick fixes.

Dr. Pifer lives and works on the West Coast, where he continues to practice medicine, write, teach, and build LifeLab as a platform for restoring health in an increasingly unhealthy world.
