I have it!
For me, it was an eye opener because I didn't really know how the body worked, how food worked in the body and all of that.
It was my first realization that I didn't know anything about losing weight, food, and my body.
It didn't make me into a great "dieter" but it did open my eyes to start reading and addressing the fact that I was overweight.
I think you should read it, go to the library if you don't want to commit to buy and see if it gives you any new information.
