Research has shown that cancer thrives on glucose and glutamine. In fact, cancer cells obtain as much as 95 percent of their energy by breaking down these two fuels through a process called glycolysis and the Krebs cycle. Conversely, one way to starve ravenous cancer cells is to simply deny them their preferred fuel.

The diet that does this quite effectively is the ketogenic diet. It is a diet which severely restricts carbohydrates (particularly refined carbohydrates), while promoting higher levels of healthy fats and adequate protein to bring about a state of ketogenesis. Healthy cells, which can survive on ketone bodies and fatty acids, continue to function normally while tumors may shrink or even disappear.

Science has shown that glioblastoma responds especially well to a ketogenic diet. Seyfried: “No tumor cell can survive in the absence of both glucose and glutamine, especially when ketones are used to support the viability of normal cells.”
