Top critical review
Not what it could have been.

I really, really wanted to like this book. I have read two of Dr. Fung's other books: Obesity Code and his Guide to Fasting, articles from his IDM blog, as well as watched many talks and videos by him on youtube.
I eagerly pre-ordered this book, as I was hoping to reconcile the conflicting messages from the low-carb lifestyle community and the longevity recommendations from other books, such as Blue Zones, Brain Rules for Aging Well, Spark!, and Aging with Grace (a wonderful book on the Nun Study). The book sort of answers this question by promoting a plant-based (but not vegetarian) diet (similar to Blue Zones and other evidence promoting plant-based) within confined eating windows (intermittent fasting, which brings the benefits of light ketosis). I like this idea as I find it much less constraining than ketogenic regimes, and I also find it very easy to follow.
Having said that, the book felt more like a rough draft compilation of one-off recommendations (chapter after chapter about beverage choices...), mixed in with blatant product placement ads right in the text. I found this very disappointing, especially after Fung's straightforward and common-sense messages from Obesity Code and Guide to Fasting. If you are expecting the same quality of work, you will be disappointed.
If you are just beginning your book research into aging well, try any of the other titles I've listed above for a more well-rounded approach. I am not afraid of getting old, I am afraid of getting *old and sick*. Other books have addressed this concern for me much more completely than Longevity Solution. If you are brand-new to Dr. Fung's work, I would recommend his other two titles- Guide to Fasting and Obesity Code (I am not overweight, but read this book because of a family history of both middle-aged weight gain and diabetes, I found it extremely useful for preventative practices.)
