Exactly what toxins does your chiropractor or nutritionist believe you have in your colon? And what is the evidence that $300 of special stuff actually helps other than helping the practice pay its rent? You want to use diarrhea for weight loss, how about a jar of Miralax or just await your next colonoscopy. Chelation can't be far behind.

Changes in weight loss and lipid profiles after a dietary purification program: a prospective case series
Done at a Chiropractor school it had a total of 7 patients all student age not seniors. They were put on essentially a very low near starvation diet and guess what, they all lost weight in the short term. No long term follow up was done. This proved that not eating can reduce your weight. I don't charge for that high level of wisdom. No toxins were discovered, analyzed, tested, assessed, or even mentioned. But TOXIN is such a good scare word it might help to sell a product, hmm.
