Combat & Compassion with Vegan MMA Fighter Mac Danzig

Jan 4, 2023

To talk to today’s guest, you may not guess he’s an extremely accomplished mixed martial artist. Modest, thoughtful, and incredibly insightful, Mac Danzig is a true maverick – a warrior poet and animal rights proponent who defies stereotypes and can wax philosophical about anything from human nature to photography, even skateboarding. A 2nd-degree black belt in Brazilian jiu-jitsu, he came to prominence while winning season six of the Ultimate Fighter and made his mark in the ring as a dominant grappler and proficient striker. In addition to his success in the Ultimate Fighting Championship, he appeared in the revolutionary documentary Forks Over Knives, where he discussed the benefits of a plant-based diet and how it affected his health and his career as an athlete.

Today, Mac has his own MMA studio where he passes on what he’s learned to a new generation, and we’re really happy to have him on!

The Plant-based Playbook IS HERE!

Let the Plant-based Games Begin, the first-ever guidebook dedicated to optimizing athletic performance with plant-based fuel. We developed the Playbook in consultation with the IOC’s Office of Sustainability to help coaches, dietitians, and athletes understand how to embrace plant-based nutrition.

Researched and written by a diverse group of highly credentialed researchers, clinicians, and athletes, the Playbook leverages peer-reviewed science and real-world experience to illuminate the physiological benefits of a plant-based diet. The Playbook also includes robust, field-tested tools and resources for meal planning and other practical implementation techniques.
