Body Cleanse.... do you believe in it?

I've known a few people who were all up on these types of body cleansing techniques. Of the few things they all had in common was a disdain for modern medicine as well as regular illness. One friend of mine nearly killed himself trying to stick to one of these plans. He was doing the whole bit, colonics, supplements, crazy diet, etc. He was a whisp of a person before he started eating properly again. Trying to help, and not being a stranger to digestive health troubles, I asked him how many doctors he had seen. He had seen a total of 1 actual doctor. He had visited numerous quacks all promising to heal him without the help of the evil medical industry.
