About the Author

L. Amber O’Hearn has an eclectic background, with academic publications in several fields including theoretical mathematics, cognitive psychology, computational linguistics, and more recently, evolutionary nutrition and biology. She has been studying and experimenting with low-carb, ketogenic diets since 1997, and is particularly interested in evolutionary constraints and interspecies differences. Amber has been eating a nearly plant-free diet since 2009.
