Why ketogenic diets can be useful for dogs with cancer, and the basic way to create one. Based on the research below.
A good, in-depth discussion of ketogenic diets for cancer in humans. (There is a study being done on canine cancer patients which has shown its value for dogs also.)
The first reported case of glioblastoma treated with both conventional therapy and a restricted ketogenic diet. No steroids were necessary. (Usually steroids are needed with conventional therapy to reduce swelling of the brain.) The diet was changed to calorie restriction only without inducing ketogenesis when an increase in uric acid was seen. After none of the tumor was found, calories were increased and the tumor recurred. Perhaps if they had kept the patient on a modified ketogenic diet with less calorie restriction at the end, the tumor would have taken longer to recur.
An explanation of why conventional treatment of brain cancer can actually help brain cancer grow, after an initial improvement in symptoms.
An explanation of Seyfried's therapy which adds calorie restriction to the ketogenic diet. While his restrictions are a little extreme, he uses them for end-stage brain cancer patients, with generally good results. In general, cancer patients that eat as much as they want of a ketogenic diet do not have nearly as good results as those restricted to normal or below normal calorie intake, along with the ketogenic diet.
Glioblastoma is a highly malignant cancer that is poorly controlled by conventional therapy. This article discusses why a ketogenic diet can be helpful for this type of cancer, especially because conventional therapy can release factors that help tumors grow.
