This guy is a chiropractor, so keep that in mind. He’s a former Olympian and he experiments on himself. He’s against dry fasting, but the science seems solid and he is generally balanced. Worth a watch if you’re curious.
I’m not sure an appeal to authority works when the credentials in question are “former Olympian chiropractor.” You might get a few more bites if you entertain us with what you think this “generally balanced,” and “solid,” science is, exactly.
