Canadian born Amber O’Hearn, M.Sc., is a data scientist by profession with a background in mathematics, computer science, linguistics, and psychology. After moving to the U.S., she began experimenting with different forms of diet, in order to retain her health and balance her mental state.

She has been studying and experimenting with ketogenic diets since 1997. More recently she has begun writing and speaking about her findings. Her review on the evolutionary appropriateness and benefit of weaning babies onto a meat-based, high fat, low carb diet, was included as testimony defending Prof. Tim Noakes in his recent trial. Amber has been eating a carnivorous diet for over 8 years.
