nonfiction/recipe companion book to Wahls' other book (Functional Medicine, holistic healing through food, Keto and non-Keto recipes).
This didn't go into the details of the why (for that you have to read the first book, I guess), but I liked that this is a practicing doctor who became a Functional Medicine convert (after reversing her multiple sclerosis symptoms with diet), and who still practices licensed medicine--NOT a less-credentialed person who makes money primarily through selling books and products, as you often see in this field (lots of desperate, terminal people provide a big market for quack schemes, unfortunately).

I also really liked that this provided recipes for three different levels of the Wahls' diet, each progressively more extreme/difficult, so that one can either stop at the level that suits their personal health, or can use them to ease themselves into the most difficult and extreme level, the Keto diet (ketosis is when your body has no sugar/carbs to burn, so it burns your fat--it is apparently super effective in speeding up the recovery time of surgery patients and even patients with Stage 4 cancers, but of course in order to get to ketosis you basically have to eliminate all sugars and carbs from your diet, so you've really got to be serious about it). Fortunately, this book includes recipes for the rest of us.
