1385-Ketogenic diet mediates intestinal tumorigenesis

Paper Talk · Aug 4, 2026 · 21m

This research explores how a ketogenic diet (KD) influences intestinal tumor growth, specifically within the small intestine of mice predisposed to cancer. The study reveals that while a KD increases small-intestinal stem cell activity and accelerates tumorigenesis, these effects are driven by the oxidation of dietary fats rather than the production of ketone bodies. Through genetic manipulation, the authors demonstrate that neither inhibiting nor augmenting ketone metabolites impacts tumor burden, contradicting previous theories regarding the tumor-suppressive nature of ketones in this…
