Gut-Brain Effect on the Kinetic Chain
A lowered supply of neurotransmitters in the gut lowers your drive, or volition. In prehistory, this would have given the caveman the signal that it was time to stop fighting sabre-toothed tigers for the day and go home to rest. Naturally, while recovering from whatever injuries or stresses he endured during the course of his extremely demanding existence, he would have indulged in a meal or two, eating whatever was available – whether it was freshly foraged or killed.
That food – fresh, “local”, unrefined – was densely packed with nutrients and prebiotics. It was food ideally suited for gut health.
The idea is that primal man had a heightened requirement for movement. If he couldn’t move or didn’t move, he was dead. And when he did move, there was a built-in mechanism to let him know when movement needed to stop for the day. He went home rested, ate, recovered, and then went out and did the whole thing over again the next day. This is the same thing you have to do if you’re an athlete looking to improve your performance – go out, create stress through training, recover, and do the whole thing over again.
