The people who have the highest levels of B12 have the biggest brains—you can correlate B12 levels with brain size.

Pretty much substantially throughout the carnivore community, the removal of fiber improves gas, bloating, and constipation across the board.

The studies are pretty clear—the inclusion of fruits and vegetables has no change in the incidence of cancer.

This is what I hope Western medicine will realize in the near future: there's this huge lever that they're not pulling; elimination diets—if constructed intentionally and with forethought—can be so powerful.

There are epidemiology studies in China that show men who eat the most meat have the lowest rate of heart disease and women who eat the most meat have the lowest rate of cancer.

For me, living a genius life is about trying, as best we can, to understand truth in all aspects of our lives—in terms of relationships, in terms of science, and in terms of health.
