I am also very curious and will hope for a response from someone far more knowledgeable.

However, from my own research and experience I actually think there is no real answer someone else can give you. All of our bodies are different. Beyond that, the dietary advice we all choose to follow is even more different. I have a friend who basically fasts yet works out twice a day. I myself do something reminiscent of intermittent fasting with a touch of keto macros and do fairly well. Others follow a more "typical" diet and do just fine in their own ways.

My point is, get some basics and then just see what works for you.
