7. Clinical application of ketogenic diet

8. Ketogenic diet in cancer therapy • 1987, Tisdale et al. : decreased tumor weight and improved cachexia in mice with colon adenocarcinoma • Reduce tumor growth and improve survival in animal models of malignant glioma, colon cancer, gastric cancer, gastric cancer, and prostate cancer

10. In Cancer increase in cell glucose metabolism as well as alteration in mitochondrial oxidative metabolism • increase mitochondrial DNA mutation • ROS increases • Increased tumor cell ROS increases tumor cell dependence upon glucose metabolism, resulting in generation of NADPH and pyruvate via the pentose phosphate shunt and pyruvate from glycolysis. • NADPH and pyruvate reduce hydroperoxides.

12. Ketogenic diets decrease the capability of tumor cells to produce NADPH because, in most tissues, fat metabolism is unable to undergo gluconeogenesis to form G6P necessary to enter the pentose phosphate shunt.

13. Thus, ketogenic diets should further increase the oxidative stress in tumor cells relative to normal cells by limiting NADPH regeneration.
