Along this line, my friend, Mark Cucuzzella MD, who is on the faculty at WVU School of medicine, wrote
this.
As well, my friends, Shelley Schlender and Ivor Cummins both separately interviewed Ron Rosedale MD. Shelly's is

here. Rosedale's message is the same in both interviews - basically you can change your metabolism by changing you diet in very short order - like days.
I've not listened yet to Bikman, but I've heard him speak previously, so I'm pretty I know his message. The above agree with him.
