Query: This is a book? It seems more like a pamphlet

I really wanted more substance in this book. Short little chapters, very little detail about diets, about the body, about why this diet is better or as good as other diets out there.Basically you get a few pages welcoming you to the diet and then a list of foods to include and not include. That's not a book. That's a grocery list. I like the doctor a lot on the TV show but I hate to say the "book" is a little light weight.
