Mark Sisson (born July 20, 1953) is an American fitness author, food blogger, and a former distance runner, triathlete and Ironman competitor.[1] He frequently posts to his website and blog, Mark's Daily Apple.
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.[2]
Sisson and his wife, Carrie, have two children.[3] He is a follower of the paleo diet[4] and markets his own version of it, called the "Primal Blueprint" diet.[5] As part of this initiative, he started a food blog, "Mark's Daily Apple," in 2006 and has also written a number of diet and exercise books,[6] including the bestselling book, The Keto Reset Diet: Reboot Your Metabolism in 21 Days and Burn Fat Forever.[7]
Sisson finished 4th in the February 1982 Ironman World Championship.[8] In the 1970s, he was a record-setting runner for the Portland (Maine) Track Club.[9] He 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.[8] 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.[8]
In 2015, Sisson and Morgan Buehler co-founded Primal Kitchen, "an authentic, premium and growing brand that ... offer[s] health-conscious consumers the best possible choices in Condiments, Sauces, Dressings and Healthy Snacks." In 2018, Kraft Heinz announced a definitive agreement to acquire Primal Kitchen for approximately $200 million.[10]
In 2021, Sisson and his son, Kyle Sisson co-founded Peluva, a barefoot shoe brand "designed to enlighten your natural movement in all of life's moments and transitions".[11] [12]
