By Diane Bartz WASHINGTON (Reuters) – Americans putting their faith in miracle cures to shed unwanted pounds are likely to be disappointed, U.S. regulators said on Tuesday in announcing settlements with four firms accused of falsely advertising weight-loss products such as skin creams. The Federal Trade Commission won agreements from L’Occitane, Inc.; The FTC also urged media outlets to scrutinize advertisements more carefully to avoid publishing potentially misleading ads, noting that some of the advertisements for the products – from food supplements to skin creams – appeared in mainstream publications.
