Looks like Dr. Westman put together a video covering his intro at his clinic.  It’s a great resource if you are contemplating a low carb/ketogenic diet, or you have someone in your life who wants to know more about it, is suspicious about it and thinks its a crackpot, non-scientific approach. Dr. Westman is a respected physician working at a respected medical university.

Funny how people have an easier time believing the crackpot on TV than someone like this.
