Okay, here is my personal stuff. I am a middle-aged woman, enjoying primal, getting back to it after a recent hard time. I have fasted before, am doing it for autophagy (cell renewal), and will be happy with any weight-loss that comes. I am planning to do a 2-4 day electrolyte-water fast. (Water mixed with some lemon juice and salt.) My start day will be January 1, 2013.
