How to Starve Cancer: A Practical Patient's Guide to the Ferroptosis Protocol Step-by-Step Checklists, Actionable Frameworks, and Support Strategies for Patients and Caregivers

Dr. Casey R. Klapper has spent more than fifty years in the field of oncology, working alongside patients as a physician, coach, and counsellor. He began his career in the late 1970s, at a time when cancer treatment was dominated by surgery, chemotherapy, and radiation—and when the idea that diet or metabolism could influence cancer was largely dismissed by the medical establishment. Over the decades, Dr. Klapper has witnessed the evolution of oncology, from the early days of cytotoxic chemotherapy to the rise of targeted therapies and immunotherapy. But it was the emergence of metabolic oncology—the study of how cancer cells use energy and nutrients—that truly captured his attention and transformed his practice.

Dr. Klapper trained at the Royal College of Surgeons in Ireland and completed his residency at St. Bartholomew's Hospital in London. He was among the first physicians in the United Kingdom to incorporate metabolic interventions into cancer care, and he has worked with thousands of patients over the years, helping them to integrate the metabolic approach with conventional treatment. He has been a vocal advocate for patient empowerment and for the importance of lifestyle factors in cancer treatment.

Throughout his career, Dr. Klapper has been guided by the belief that patients should be active participants in their own care. He has seen firsthand how the metabolic approach can change the trajectory of the disease, even in patients who have exhausted all other options. His experience with patients like Jane McLelland, who developed the metro map and the cancer-starving cocktail, has shaped his approach and inspired him to share his knowledge with a wider audience.

Dr. Klapper is a regular speaker at conferences on metabolic oncology and has published numerous articles and book chapters on the subject. He is a member of the Society for Metabolic Health and the Metabolic Oncology Network. He continues to practice in London, where he works with patients from around the world, and he is committed to advancing the science and practice of metabolic cancer therapy.

Outside of medicine, Dr. Klapper is an avid gardener and a passionate advocate for sustainable living. He lives in London with his wife, Margaret, and their two dogs, Charlie and Daisy. He remains deeply inspired by the courage and resilience of his patients, and he believes that the greatest lessons in healing often come from those who face the greatest challenges.
