FDA Warns Against Diet Pills Sold on the Web

WASHINGTON -- If you're looking for a little help shedding extra pounds after the holidays, the government is warning you to stay away from nearly 30 weight-loss products that contain unlisted and possibly dangerous ingredients.

The pills are advertised as "natural" fat busters and have intriguing names like Imelda Perfect Slim and Zhen de Shou. Some are touted as new versions of "ancient remedies" from Asia.

They may promise an easy fix to weight problems, but the Food and Drug Administration on Monday said the concoctions contain unlisted ingredients, including high doses of a powerful anti-obesity drug, as well as a suspected carcinogen.

"When consumers are buying these products online, we're telling them that if it sounds too good to be true, it is likely to be too good to be true," said Michael Levy, an FDA lawyer who works on enforcement issues.

FDA lab testing found 28 dietary supplements that could land unsuspecting users in the emergency room. Most of the diet pills appear to be coming from China. They are mainly sold on the Internet.
