ValerieDI’ll let Anne-Marie answer your questions in depth, because, obviously, she knows more about it. "BFL" stands for "Body for Life" - I think it was started by a man by the name of Bill Phillips. The "Zone" refers to the Zone Diet by a Dr. Barry Sears (Once again, I think that is his name!). Each has their own website if you want to check them out and as I mentioned in my post, The Discovery Health Channel broadcasts people taking on the 12 week BFL Challenge and chronicles them for the entire time so you can see the progress. It is very inspiring.
