The Personalized Diet: The Pioneering Program to Lose Weight and Prevent Disease

An inspiration for Levels, but could be a lot shorter. The universal best diet doesn't exist because people respond differently to foods. The best way to find out how you respond is to measure it. Unfortunately, the end of the book, with the actual protocol, is disappointing. They recommend using a finger prick, and taking a few point measurements after meals. From my own experience wearing a continuous glucose monitor, this is far too noisy.
