Starting a fasting journery - where to beginning

Hello, i would love to see how fasting works for me andmy body. I have been about between 210 and 225 back and forth with working out and changing my diet and still not feeling like i am losing my weight needed. I have been working out consistently for the past 2 years about 30 mins monday through saturday and not getting anywhere. Can someone guide me in books that i could ready to help me start looking to see if fasting is for me and worth my time etc I want to get under 200pds and stay there. I do like working out and eating healthy but want to bring in the benefits of fasting as well.
