If you are interested in the topic, this will bring up links to the work being done at Boston University on calorie restricted ketogenic diets and brain cancer. https://www.google.com/search?q=boston+university+cancer+ketogenic Here is the head of the program http://www.bc.edu/schools/cas/biology/facadmin/seyfried.html and an interview with him from Jimmy Moore's podcast http://www.thelivinlowcarbshow.com/shownotes/1172/dr-thomas-seyfried-on-killer-carbs-ketosis-as-a-cancer-cure-episode-302/ Here is a quote, from Carbwire's blog, about this episode: "You'll hear Dr. Seyfried talk about his original interest in the subject of ketogenic diets for epilepsy when he was at Yale University (and the lack of interest in them at the time), how a ketogenic shrinks brain tumors, the details of his KetoCal study, the controversy over using mice instead of humans in his study, what "calorie-restriction" translates from mice to humans, why a 400-500 calorie, ketogenic diet will make you "metabolically healthy," whether a ketogenic diet is useful on other cancers, why the ketogenic diet is a "non-toxic approach to the management of cancer," the best diet to eat for the prevention of cancer, and why a 7-10 day distilled water-only fast annually is the best way to ward off cancers of all types.
