At the recent Physicians for Ancestral Health Winter Retreat I had the opportunity to sit down in person with L. Amber O’Hearn, an outspoken advocate of plant-free eating. Since learning about the zero-carb carnivore approach in 2009, Amber has become an international speaker, researcher, and writer on the subjects of ketosis and the health benefits of eating meat.

In this podcast, Amber and I discuss her health journey from veganism to low carb, and then to the more radical carnivore diet. She explains how shunning plant foods led to a dramatic improvement in both her physical and mental health, ending her 20-year battle with bipolar disorder, without the use of medication. She also describes her own version of zero-carb and discusses how a carnivore diet affects ketosis.
