I'm a bit late to the Dr Ken Berry fan club. He is a PCP in a small Tennessee town, and has a YouTube channel, a book, Lies My Doctor Told Me and is working with one of the 2KetoDudes. He's been everywhere lately, conferences, podcasts, etc. I Finally got around to watching his Diabetes warning video, Diabetics Beware: ADA Guidelines will make your Diabetes Worse. It is a direct appeal to ignore guidelines, just as Dr Hallberg's TEDTalk message works for others. He is a smart guy, accept the accent and basic video skills...a straight forward message that should be in this forum.

Under the YouTube are links to his book and other information on a very LC Diet, etc.
