Have you noticed any positive benefits at all since being back on a regular diet?
I always observed that the worse I felt during the fast - the better I felt afterward.
So if I was feeling bad I knew that there would be equal benefits to the degree that I felt bad.
I could count on it every time and this was with one, two and three day fasts.
Also it is important to break these fasts in a proper manner.
Its of course not OK to head to Burger King for the well deserved first meal to break the fast with.
Paul Bragg's book "The miracle of fasting " is great for guidelines on breaking the fast of different lengths.
