Therapeutic Fasting: A Clinical Manual for Metabolic Reset and Renewal

In the right conditions, restoration can begin on the cellular level.

In Therapeutic Fasting, physician and integrative medicine expert Dr. Thomas Lodi, MD, draws on nearly four decades of clinical experience to present a straightforward, medically grounded guide to supervised water fasting. Designed for both practitioners and health-conscious readers seeking natural healing, this guide walks you through the complete science and structure of medically supervised fasting — from first principles to long-term maintenance.

Organized across five parts, Dr. Lodi covers:

The science of fasting and the body's metabolic phases Preparation protocols, exclusion criteria, and dietary readiness Sleep, cortisol rhythm, hydration, and movement during the fast Monitoring vital signs, the glucose-ketone index, and what to expect day by day A safe, structured refeeding framework Long-term fasting cycles for sustained cellular health The manual also includes five practical appendices — required materials, environment setup, support tools, a self-monitoring workbook, and a foundational literature guide — making it a complete clinical reference, not just a reading experience.

Written with clarity, clinical precision, and deep respect for the body's innate intelligence, Therapeutic Fasting invites readers to reconsider fasting as a pathway to biological balance, cellular renewal, and lasting health.
