The government charged that the makers of Dream Away diet pills have no basis for their claim that consumers who take the product can lose weight while merely sleeping. The FTC alleged that TV ads and other promotional materials violated federal truth-in-advertising laws. The agency made the charges in a suit filed in Arizona federal court. The suit named Kingsbridge Media & Marketing Inc. and Frank Robinson of Van Nuys; and Highcliff Inc., Nutri Marketing, Vista Advertising, and Mel and Steve Korey, all of Scottsdale, Ariz. The companies and individuals had no comment on the suit. U.S. District Judge Earl Carroll issued a temporary order freezing their assets and barring the claims.
