Therapeutic Fasting

Thomas Lodi, MD, MD(H), is an integrative and homeopathic physician with more than four decades of clinical experience. After graduating from the University of Hawaii School of Medicine in 1985, he completed formal training in internal medicine, served as a visiting clinical fellow at Columbia University, and later taught at his alma mater.

Dr. Lodi’s professional path began in clinical psychology, where he provided services at a 240-bed inpatient facility in Hawaii. Following his medical residency, he spent a decade in intensive care units and urgent care centers before leaving conventional practice in search of less toxic and more effective approaches to healing. Over the next two years, he trained extensively across Japan, Europe, Mexico, and the United States in bio-oxidative, anti-aging, regenerative, and functional medicine, a foundation that would shape the next three decades of his work in integrative oncology.

It was that work that brought him to fasting. Treating patients whose conditions had not responded to conventional approaches, Dr. Lodi found that therapeutic fasting, applied carefully, with proper monitoring and the right protocols, produced metabolic shifts that few other interventions could match. This manual is the clinical distillation of what he has learned: how fasting works, when to use it, how to do it safely, and what to track along the way.
