Finally, a scientific and fact based explanation of the ketogenic diet. Harper explains in straightforward terms the how and why of the ketogenic diet. He explains how it is increasingly supported by evidence, exposes many diet and nutrition myths floating around, and explains how many previous studies were flawed. Not a recipe book, there are plenty of those out there. This is the book to buy if you are on a ketogenic diet and need some ammunition in discussions with family, friends and self-professed experts who quote their own favorite diet 'facts'.
