Page discusses it indepth
"In a dry fast, the body does not eliminate toxins in the same manner as it does during a water fast. Instead of removing toxins through the normal channels of elimination, skin, liver, kidneys, urine, and bowels, it actually turns each cell into a tiny incinerator and burns the toxins up inside of the cell. One thing I have noticed since I started dry fasting is that I have almost no
Body Odor or bad breath during a dry fast, while I always experienced this during a water fast. Each day of a dry fast is said to be equivalent to 3 days of a
Water Fast in terms of detoxification, so you accomplish much more in a shorter time. The good thing about this is that a person does not need to take a long absence from their normal life, so it costs less both for the fast itself (if you are going to a facility to be supervised) and for the time taken off from work. Also, you lose less muscle mass and more body fat with dry fasting, than you do with water fasting, and the recovery time is quicker. Returning to normal function after a 10 day dry fast is much faster than after a 30 day water fast. "
