Congrats to this guy on his accomplishment! Some quotes in this article show why it's not good to rely on opinions of government-type entities and registered dietitians who were taught the received wisdom of the day that doesn't always align with science. They don't seem aware, for instance, that the human body makes its own carbohydrate from other fuels as needed therefore requires no dietary carbohydrate. I like to get my health information from carefully researched sources rather than popularly held opinions.
