Query: I learned so much by reading this book!

I love this book. I have read most of it cover to cover, and I have about 3 chapters left and I feel like already I am making smarter diet and fitness decisions. It has motivated me in that I think about what I put into my body and what I do to excercise....I cannot wait to start the YOU on a Diet book.....I bought it and am going to read it next. I highly recommend this to anyone who enjoys learning and wants to improve their quality of life by simply learning what your body needs to operate at its best.
