Query: Content and concept are reasonable

I enjoyed reading the book and learning about the concepts of food combining, metabolism and appetite satisfaction. The content of the book and its author makes for very believable reading. I am comfortable with this way of changing my eating habits; it's no hassle. I believe however, that I should lose more weight so I will stay with the program. I would like to know why it is not working for me as well as it should. What could I be doing wrong? Goodbye funky foods forever. I pretend I am allergic!
