Yes, the 8 oranges per day as explained on the web site. The 8 orange per day was the best medical fasting I have ever read. Done properly I know of no better fasting experience.
I often juice 30 large oranges per day, but I am in no hurry and this just slows the fast down, then some days I may not drink any juice. For those with no past experience, I always suggest sticking to the book perfect fasting methods that made medical history.
