Fasting. Advice. Motivation. Help?

I used to fast in April and May of 2011 for 4 days every time, altogether maybe 20 days. And I am christian and also fasted for both religious and diet/weight loss reasons. The results turned out amazing to me. I lost over 20 pounds and my problem was almost solved, still working....To be honest, the process was not easy, and sometimes I really starved but once I passed the critical moment, I felt better with more energy to go on. The secrets are trying to do something else, not focus on food.
