Interesting idea. But even if there is a talented, convincing speaker you still need someone who wants to listen. Are there numbers on how many people who are not interested in dietary changes listen to such speeches?

I guess it all depends on what you want to achieve. Are you unhappy with your life? Do you want to change something specific? What keeps your from changing it?

I guess all these questions can be answered rational by searching your feelings and looking for facts. My two cents. (I'm also trying to understand all this. :)
