I intermittent fast everyday, apart from when I run long distances (more than 10 miles). I also do a 24 hour (sometimes more) on a Monday which is when I don't run at all.

Doing this has helped my sleep so much and my productivity has gone through the roof.

I don't do ketogenic though, I believe a good source of carbs in our diet is fine. I tend to get mine from sweet potatoes. I stay well away from refined sugars though.

I agree that good sources of carbs are fine as well. The human body is amazing such that there is no end-all be-all diet for it and its able to adapt efficiently to healthy diets.

I actually do a high-glycemic (talking baked sugary madness) load/refeed around intense workouts every once and awhile; also keeps me sane.
