I am sure there are many Paleo diet programs and podcasters which are worth mentioning, but I just wanted to point to a couple who seem to have rapidly growing followings and who strike me personally as very much on the mark. Chris Kresser has a particularly quickly growing practice in Berkeley where people are struggling to just get on the waiting list. His podcasts are fully transcribed with lots of references. He also provides many free e-books when he could likely be profiting otherwise, and seems commuted to making his information available for free to the public I encourage people to check them out
