My weight loss documentary, The Obesity Tapes, is now online at billnagler.com and dietresults.com (click the video link on the home page) and on youtube (search The Obesity Tapes). In the fall of 2011, I began interviewing the best diet doctors in the country. I asked everyone the same 2 questions. What do you think happened that we got so fat? And what are the best things you do that help patients lose weight? These conversations contain the real secrets of weight loss, from the best American diet doctors in the trenches. The documentary runs a little over an hour. I think you’ll be as surprised as I was at what I found out.
