Query: motivational and easy to follow

I like the use of "twin studies" by the authors - they put themselves through the rigors or programs that they ask us to follow. I found the book easy to read, nutritional advice sound and relatively easy to implement and a book that was not hokie in this day and age of gimmicks. I recommend this book as a nice starter and primer for weight loss guidance.
