Query: Five Factor Fitness does not compare to Flip The Switch

I just got through reading this book after seeing the author on Jane Pauley. I'm not going to say that this book is bad, but I achieved great results with a book called Flip The Switch which was written by Diane Sawyer's trainer, Jim Karas.In Five Factor, you are told you have to do five 25 minute workouts a week. In Flip The Switch, I only had to do three 20 minute workouts and I they really made a difference in my body weight and body composition.Plus, Jim Karas really knows women, especially women with weight to lose. I found out about him in Oprah's magazine as he also helped her best friend Gail King lose a bunch of weight.I would recommend anyone interested in losing weight to check out Flip The Switch.
