Interview with mark sisson author of primal blueprint and mark s daily apple
Mark Sisson (born July 1953) is an American fitness author and blogger, and a former distance runner, triathlete and Ironman competitor. Sisson finished 4th in the February 1982 Ironman World Championship.
Sisson was born in Maine and is the oldest of four siblings. He attended Williams College, where he was a pre-med candidate and earned a biology degree.
In the 1970s, Sisson was a record-setting runner for the Portland (Maine) Track Club.
Sisson had a top-5 finish in the 1980 U.S. National Marathon Championships and earned a qualifying spot for the 1980 U.S. Olympic Trials.
Sisson served for 15 years as chairman of the International Triathlon Union (ITU) Anti-Doping Commission and as the ITU's liaison to the International Olympic Committee. He was asked to step down from the roles due to conflict of interest in 2003 when he started his own dietary supplement company, Primal Nutrition. He is a follower of the paleo diet and markets his own version of it, called "the primal blueprint" diet.
