Mark Sisson got rich teaching people to eat like a slightly modern hunter-gatherer and then sold salad dressing to Kraft. Mark’s Daily Apple, The Primal Blueprint, Primal Kitchen. Before keto was a default podcast, he was the fit older guy saying grains are optional, sprints beat chronic cardio, and you should be able to play when you are 70.
The Primal laws are almost a poster. Move a lot at a slow pace. Lift something heavy. Sprint occasionally. Sleep. Play. Get in the sun. That list has aged well. The anti-grain absolutism aged less well. Plenty of people do fine with rice. Plenty of people also feel better when they stop eating like a vending machine. Sisson’s gift was making the second group feel athletic instead of deprived.
He is living advertisement and businessman. The avocado oil mayo is not a protocol. The 70-year-old who still sprints is. Steal the movement laws. Relax the tribal diet. Pair him with Lyon if you need the protein and lifting details he sometimes leaves implied.
