Four weight-loss companies charged with making fraudulent claims

(CNN) -- That "miracle" weight-loss product you've seen on TV may not live up to the hype.

The Federal Trade Commission has charged four companies with deceptive advertising related to their weight loss products. "Operation Failed Resolution," as the FTC calls it, is an effort by the federal agency to crack down on companies' misleading claims about products that allegedly help consumers slim down.

"Resolutions to lose weight are easy to make but hard to keep," Jessica Rich, director of the FTC's Bureau of Consumer Protection, said in a statement. "And the chances of being successful just by sprinkling something on your food, rubbing cream on your thighs or using a supplement are slim to none. The science just isn't there."

Only three weight-loss drugs are currently approved by the Food and Drug Administration for long-term use by certain adults: Belviq, Qsymia and Orlistat (sold over-the-counter as Alli).

The FTC has reached a settlement with Sensa, Inc. and a partial settlement with LeanSpa, LLC., according to an FTC press release. The release also announced the charges filed against L'Occitane and HCG Diet Direct.
