Health and fitness expert, and former elite endurance athlete, Mark Sisson (@Mark_Sisson) is the bestselling author of The Primal Blueprint and one of the leading voices of the Evolutionary Health Movement. His blog, (over 1m visits per month), has paved the way for Primal enthusiasts to challenge conventional wisdom’s diet and exercise principles and take personal responsibility for their health and well-being. Mark’s efforts to promote primal living extend to a line of nutritional supplements, a book publishing company, a Primal Kitchen line with healthy functional foods, and a burgeoning Primal Kitchen fast casual restaurant chain.

Mark is a former elite endurance athlete, with a 2:18 marathon and a 4th place Hawaii Ironman finish. His new book Primal Endurance applies the primal eating and lifestyle principles to the challenge of endurance training—helping athletes overcome the common conditions of burnout and carbohydrate dependency.

I’ve been a big Mark Sisson fan for a long time. I was looking forward to having Mark on the podcast for a long while, and he did not let me down. This one is packed with health, fitness, lifestyle and business strategies and tactics. We cover:

  • How Mark builds muscle quickly.
  • Exactly how sprints combined with a moderate/high-fat diet and low-level aerobic activity cut you up.
  • Mark’s thoughts on legumes, sour cream and white rice.
  • How to eliminate the infamous “muffin-top”.
  • Mark’s life and business productivity hacks.
  • And much more!
