Along with the others i wish to express my congratulations :).
The "ten days of Water Fasting being equivalent to 30 days of juices" is in reference to the amount of cleansing and healing that is taking place, not the amount of weight temporary and otherwise that is being displaced. 10 days of juice is enough time to expel lot of "water retaining sodium" from the body which in turn equates to a temporary loss in water weight that is nearly on a par with what you would experience in ten days of water fasting.
