I would recommend David Sinclair and Jason Fung in terms of resources for this to understand first why intermittent fasting is good for you but of course appropriately applied for the individual. If you start to understand the whys and stop listening to specific people's testimonials or crazy routines in some cases (from your perspective), you'll tailor it appropriately to your life if its something you want to do. Personally, I found it quite easy to incorporate and with great benefit.
