Even 12 hours of not eating is a good start. Especially if you don’t have a weight problem.
And the most important thing is not to break the fast with anything but protein. Have an egg first, not pancakes or donuts.

I think fat is fine too, at least according to the videos out there, but definitely NOT carbs (and that includes sugar, whole grain, fruits, etc.). In fact, the longer one can abstain from carbs, even if not fasting, the more benefit they will get.
