I agree with the advice here to start slowly. I am not fasting right now because I am on the Dr. Fuhrman Eat to Live anti inflammatory diet, but usually I try to eat all my food on a given day in 8 to 9 hours, which leaves 16 to 15 hours a day fasting. Every few weeks, I like to get a one day fast in, but I am not always consistent with that. By starting slowly, and by eating plenty of food during the eating periods, it is fairly easy to maintain energy during fasting.
