It's true that dry fasting is about three times more effective than water fasting. It's also three times more likely to leave you with debilitating detox symptoms. I wouldn't recommend dry fasting unless you are already very experienced with fasting, and your schedule allows for plenty of rest. If you are not good at managing stress, do not dry fast.
As with all more restrictive methods, breaking the fast is even more important when dry fasting. It is best idea to plan for water and fruit juice for a day after the fast before eating fruits again.
The main difference between dry fasting and other types of fasting is that there is no stimulation of peristalsis (sp?). Proper breathwork and exercise is usefull to stimulate the organs to remove waste normally. Otherwise BM action will cease, and your last meal consumed will rot in the intestines. It's good if you know some kind of yoga or dancing that will stimulate internal organs.
I am doing a dry fast currently. Nothing has touched my mouth for approximately nineteen hours. The longest dry fast I have ever conducted was eight days. But I should have limited it to five days because the last three days were very difficult. Sometimes, I'm a little too hardcore for my own good.
Also be very carefull with fasting. Dry fasting can bring on detox symptoms so quickly you don't see them coming. Werdin mentions in his book that during an extended fast he suddenly had a very acute pain cramping caused by stones.
