>he's a real Dr.
Careful, he is also a believer in Ayurveda[1]. Which basically basically categorizes people into different elements like fire and water and then tries to change their diet and habits to match their elemental style or something. You can hear him talking about it here [2]. Kinda reminds me of Humorism [3]. Dr. K seems like a nice enough guy but don't get too lured in by the "Harvard-trained" credentialism.

I agree there's nuance, but he's way above the "has a webcam and yeti blue" bar that most of youtube falls under, that was my point in putting his credential up. Not to rise him to a perfect status, but to not allow him being on youtube to fall to the minimum bar of youtube.
