I don't think it's silly, esp. when you know that discussions about that these are choolesterol stones, not olive oil are done MANY times. You know the arguments, Spirit's answer in faq and posted results of a lab test.
mr. dr. Weil is one of those overweight health gurus who's enjoying their celeb status and is ignorant of an obvious thing, liver flush. He will not admit he is wrong 'cause his reputation would be jeopardized. When was the last time you heard a major heatlh guru admiting he was wrong? And that's the answer. The same as why dr. Phil will never say publicly and openly: "sorry guys I was wrong putting hydrogenated oil in my snack bars". dr Weil is palying safe, going with the flow. And he needs to loose some weight and Liver-Flush would greatly help.
