At the end of my chemo sessions, the oncologist warned me that the sequels and side effects were irreversible. Thanks to juicing and paleo/keto diet, I reversed the effects within 15 months. Otto Warburg, 1930 Nobel winner / Medicine, declared that cancer cells can only live on sugar. Cut out the sugar and they starve within 3 weeks. All animals in nature, including human cultures living in the wild beyond the kraftdinner zones, thrive on a keto regime of 80% fat, 10% protein and 10% carbs. The Gerson protocol is certainly worth invertigating. (Opinion from a person who survived cancer therapy).
