Resources for Low-Fat Cooking and Baking

Hello there! I was recently diagnosed with a medical issue that has led to me reducing or eliminating fats, such as oil, butter, and certain dairy fat percentages, in order to reduce tummy struggles, and was hoping to learn about resources, such as cookbooks, that I might utilize when trying to adapt to my new dietary restrictions. I have been adjusting recipes from some of my favorite cookbooks, but thought it couldn’t hurt to see what other resources and help there may be when considering reduced and no-fat cooking and baking. Thank you for your help!
