# Ketogenic diet affects intestinal tumors via lipids, not ketones

A study published in Nature reveals that the ketogenic diet's ability to suppress intestinal tumor growth is driven by dietary lipids rather than ketone bodies. The research clarifies the mechanism, showing that fat content itself, not the metabolic state of ketosis, mediates anti-tumor effects. This finding could refine dietary strategies for cancer prevention and treatment.
