Dr Bikman talks about how he was taught about ketones only in a negative manner in school. But he has since realized their importance. If a person has had a nutrition course in the past, they may not have an appreciation of ketones because of not only what they were taught but also what was not known about them and their importance in the body till relatively recently.
Bikman is a must listen for any diabetic or pre-diabetic. And if a person is over weight by much at all, there is a significant chance they are also pre-diabetic and just don't know it yet. So it would be good for them too.
