Has its strong points and weak points. Once again, there is no bibliography regarding the scientific information offered here. That would be really nice! But this book went further than Keto Basics in that it went into combining a ketogenic diet with intermittent fasting, which I had already decided to try on my own. This is loaded with information on that and other aspects of this eating plan, but when it came to recipes it sort of fell flat for me. Some of the instructions were bungled, many called for special ingredients I have no idea where to find, and most had lots of dairy. Still, I'm very happy with this book. And, in fact, after reading this and Keto Basics and then looking at some far inferior books that seemed to follow fads, food conspiracy theories, and just plain silliness in the writing styles, I'm going to raise my rating of both books to 4.5 stars rounded to 5. Highly recommended, for anyone interested in a ketogenic diet or lifestyle.
