I just can't fast for that many day's (2 day's tops), even if I drink some fresh juice from the juicer. I just can't take the stress of fasting for several day's, and end up on a little binge to get rid of some horrible shakes and utter grouchyness.
On the other hand I do wonderful with a light raw food diet, extra full spectrum enzymes, and then fasting at the latter part of each day and night, leaving about 14 hours for my body to rest, detox and clean out.
I have lost 90 pounds in under a year this way. And I just love the energy I get from the healthy eating and detox.
