Hi Miriam @mir123, As someone being labelled pre-diabetic most of my adult life and not believing it until joining Connect and learning more about my own health and the Metabolic Syndrome, I think one of the books I saw but haven't read it completely is one from Dr. Jason Fung - The Diabetes Code: Prevent and Reverse Type 2 Diabetes Naturally - https://www.amazon.com/Diabetes-Code-Prevent-Reverse-Naturally/dp/1771642653. He also has a great TED Talk on Intermittent Fasting which helped me quite a bit - https://www.youtube.com/watch?v=7nJgHBbEgsE.

Another of my favorites is Dr. Jay Wortman who has some easy to understand videos that you might find helpful.
