Why did Consumer Affairs call Isagenix the "Worst Diet" based on their research?

I'm trying to piece together the marketing and sales messages from Isagenix with this from the a consumer-protection organization, Consumer Affairs.

Consumer Affairs Magazine slammed Isagenix for making what they consider the "Most Outrageous Claim" in marketing the IsaCleanse product and concept   


....and continued by saying:


"Isacleanse The detox idea is seemingly the perfect scam -- it sets up a problem that doesn't exist, then provides a solution.

Ads for Isacleanse warn of toxins building up, clogging organs and deteriorating the body -- unless regularly detoxified. (This doesn't happen, as the human body is naturally self-cleaning.)

A 'healthier, leaner body' is promised in 30 days through ingesting a medicine chest full of Isagenix cures including IsaFlush for 'regularity,' diuretics, aloe pills, vitamins, ionic trace minerals, electrolyte drinks, Isalean Shakes and herbal teas.

For those who are frankly more interested in wealth-building, Isagenix turns a neat trick; on the same web page it alternately pushes a get-rich-quick scheme for deceiving others about the need to detoxify.""
