Tumor cells have more insulin receptors than healthy cells, so they preferentially metabolize glucose. When you cut off the glucose supply to tumor cells, they struggle to make the fuel they need to proliferate. The ketogenic diet sharply limits the glucose that reaches tumor cells (while providing other anticancer benefits), and animal studies (and one small but seminal human study) have shown promise in using the ketogenic diet as an adjunctive treatment for cancer. Author of the new book, Keto for Cancer, Miriam Kalamian, EdM, MS, CNS, talks with Dr. Fitzgerald about the how ketogenic eating for cancer differs from other keto and low-carb protocols and outlines specific steps for pacing a keto protocol for the specific needs of cancer patients.
