Input: Review: The proof of a book on health issues is in the results it gets you, and it's very hard to argue with the results I've gotten from following Dr. Bernstein's plan. Many others have reviewed this book more capably than I can, but let me just say that after a few months of following Dr. B's diet, I've lost 50 lbs., gotten normal blood sugars, and feel better than I've felt in years. Highly recommended!
