I think he’s primarily a businessman and salesman and his motivations are led with that. I’m not all that familiar with his stuff, but his blog has some good info, and I like the general idea with nutrition I think he’s truthful there. He seems like a smart dude. He seems to be more focused on mental enhancement than physical, not sure if he makes claims about being muscular himself at all.
His whole business started out with a product right from the get-go, the bulletproof coffee and he seems to create products to make money mostly. I like his info generally, but would take it and any products offered with a grain of salt. I noticed some higher end products too that were really expensive last time I checked, not sure how good those are but reviews on something like 40 years of Zen or whatever it’s called and other high end stuff would be interesting to see.
