Please tell me what "mildly unconfortable" solution is there for stage 4 cancer that *metastases* into brain? I only know of chemotherapy! People try diets (I prefer extended water fasting), because it affects everything! If cancer had spread into entire body, it is the only option, where you may keep your hair, and some sort of normal life!! It is also for free and does not bancrupt your family! Edit: I read the extract from study, keto was used AFTER chemotherapy to speedup recovery. Still, post chemo is nothing "mildly unconfortable". > Three months after the cessation of chemotherapy and radiotherapy, a ketogenic diet (KD) was initiated. This approach was an attempt to stabilize the disease progression after chemotherapy and radiotherapy.
