Xenadrine works worse than a placebo?!

The last line in this story about Xenadrine EFX (you know, the weight loss pill that you see commercials for during Judge Judy and Friends reruns .. well, one of them anyway, plus everyone including the stars seems to be popping it) says that people taking a placebo drug (probably just a sugar pill) lost 1 pound more than the people taking Xenadrine. Well Xenadrine? What do you have to say for yourself?
