I have just read the Schwarzbein Principle and have found it very helpful in tailoring a lo-carb diet to meet my needs. I don't have time to write a summary right now, but could answer questions that arise about the book or at least comment here and there when the Schwarzbein Principle comes up. I have also read Atkins and Protein Power. SP did the best job convincing me that my low-fat vegetarian lifestyle was not good for me in the long-term, even though it may have given me the results I was looking for in the short term. I would recommend this book to anyone who is concerned about the health issues surrounding a lo-carb approach. I would also recommend this book to vegetarians who are interested in lo-carbing (although it does not really address the issues of a vegan). I'm glad I bought it and will use it often as a reference. therese.
