I had to look up who that was.
I agree with some of it and some is a bit over the top. Nothing at all wrong with modern artificial sweeteners, not a big fan of fasting, and his pre-practice choices are crap (being a genetic mutant who may be getting a little “help” from science, he can get away with it of course).
Other things, no gluten, no added sugar, etc. are pretty much what I go by. Dairy is a bit case-specific. I typically keep it limited, but with lactose-free, organics, and a2 milks, I’ve added some dairy back in, mainly because I love my nightly protein ice cream.
