Iím not disagreeing with sd2345, but I recently read a book I purchased thru Amazon (Water Fasting: A Comprehensive Guide & 40-Day Water Fast Personal Journal, by Jennifer Thompson). I paid too much for the book ($20), which was really Jenniferís personal journal, but it turned out to be really riveting. On the 8th day of her Water Fast she started passing worms. She was shocked, had no idea, and it motivated her to continue her fast longer than she had initially intended. She fasted 40 days and expelled worms almost daily right up until the end. I should mention she was giving herself daily enemas (most experts donít recommend doing that, but thatís what she did). She described how the worms grew thinner and thinner as time went on because they were being starved. After she ended her fast she took on a parasite cleanse to ensure she got all the little buggers and any residual eggs. Anyway, her story would seem to suggest that Water Fasting can indeed kill parasites. I guess you could argue that just because she was flushing parasites out with water doesnít mean the fast was killing them, but she did describe how emaciated they were becoming day by day. She was giving herself enemas from day one, but they didnít start flushing out till day 8, so it seems that the fast weakened them sufficiently so that they couldnít Ďhold oní. And I donít know what would have happened with the parasite issue had she not been giving herself enemas (would they have withered but survived?). Anyway, just putting that out there. I guess it can be interpreted in more than one way.
