I read the sample and asked my endocrinologist about it, since he has told me for years that I am insulin resistant.  His dietitian and pharmacist researched the book thoroughly and said it matched information the dietitian gives their patients.  They highly recommend it.  I have high blood pressure, high cholesterol, and high triglycerides.  I have been diagnosed with Syndrome X.  I hope following this plan will help lower these and my need for insulin and Metformin.
