What does it take to challenge conventional wisdom, risk everything, build a $200 million company, and still have the determination to start over at 73?

In this episode of The Determined Society, Shawn French sits down with Mark Sisson, founder of Primal Kitchen and Mark’s Daily Apple, bestselling author of The Primal Blueprint and Born to Walk, and co-founder of Peluva, for a conversation on entrepreneurship, health, longevity, failure, discipline, and the courage to trust your convictions.

Mark shares how his pursuit of elite athletic performance compromised his health, leading him to question conventional nutrition and exercise advice. From failed businesses and public criticism to risking his home on Primal Kitchen and eventually selling the company to Kraft Heinz for $200 million, his journey was built through years of setbacks, reinvention, and determination.

The episode dives into:
Why being extremely fit doesn't always mean being healthy
Challenging conventional nutrition advice, including paleo, keto, and the Primal Blueprint
The failures, financial risks, and decisions behind Primal Kitchen’s $200M sale
Why Mark believes walking, foot strength, and proper footwear are essential to longevity
Starting Peluva with his son and learning to lead by letting go
Overcoming fear of failure, embracing discomfort, and finding purpose at 73
Why determination matters more than motivation

This episode is for entrepreneurs, athletes, health enthusiasts, and anyone afraid to pursue an idea because others think it's crazy. Mark's story is a reminder that failure doesn't have to be the end of your journey. Sometimes it's the beginning of everything that comes next.
