Attenuating effects of the ketogenic diet on colorectal cancer (CRC) cell growth has been previously described. Here, using a mouse model of CRC with a humanized microbiome, the authors identify a shift toward gut bacterial species that produce stearic acid in ketogenic conditions, resulting in elevated levels of free stearate in the gut lumen, which they then show exhibits tumor-suppressing properties.
