Right now I'm doing 16/8, with 3 full meals a day, and I also spend one day a week in full fasting.

IMHO, the current status of nutrition is very divergent, almost every habit is backed up and discouraged at the same time by more than one study. There seems to be some agreements (about sugar, for instance) but the rest is not clear at all. And on top of it, you have to take into account how your own body reacts to a particular habit. Seems that trial/error is the best option for now.
