Check out Robb Wolf's twitter rant Sept. 20 after the podcast came out. A listener got all worried about her carbs and he admonished her to do her own thinking. The zero tolerance for carbs stance is likely the result of the doc effectively using ketosis as a tool to reverse brain disease for many years. I loved the podcast, but Selecting makes some great (and troubling) points above. I was very surprised when he suggested Robb give up his sweet potato and get fully keto-adapted. Robb talks about this a little more in episode 203? with Kiefer of carb backloading fame.
