Ever Want to Be a Lab Rat?

We love a good hoodia ad. Here's one in which a woman goes from fat to skinny, then gets fat again before your eyes. Guess it can't be pegged false advertising if she balloons back to original size, and if the company shrouds a very clear promise under the guise of a study, rather than overtly promoting "the new magic bullet" of weight loss.

Did we ever work out what the old magic bullet was?
