How much time in between prolonged fastings do you believe is healthy to do it? I'm pretty interested in finding a good time eating - time fasting intervals where I could take advantage of the energy given by the fasting time and the reload of food in our bodies? Hmmm a guess for me (I don't know about the topic) would be a 10 days each 2 months, maybe? You did some kind of exercise or some activity that required big efforts?
