The first time I fasted 4 years ago, it cleared up the brain fog (for lack of a better description) that had been an ongoing issue for about a year prior to that. The difference was extremely noticeable and happened overnight. Since then I've always noticed increased mental clarity and energy after fasting (minimum 24 hours - strictly water only).
Increased mental clarity, energy and feeling of wellbeing is quite real. What exactly are you expecting to happen within 24 hours? Super powers? 10 years increased lifespan?
I was hoping for information on the effects or longer term, repeated fasting, as the article lays it out. It would seem that 24 hours of fasting has the same effects as going for a jog.
Not the same as going for a jog. I had been regularly exercising intensely for 10 years prior to that. It's not the same effect. To understand the longer term or scientific viewpoint, there is an abundance of research on the benefits of caloric restriction. Just Google it (on http://scholar.google.com/).
