Jenny Craig, one of the world's leading authorities on weight management, chose Mariah as their new Brand Ambassador in 2011. “I'm just here as a catalyst,” Mariah said. “Ideally this will help create awareness — my goal is to at least make a difference.”
The campaign started with a series of teaser videos with no mention of neither Mariah nor Jenny under the title Unzip X. On November 8, Mariah was revealed as Jenny's new brand ambassador. She filmed additional commercials for the brand, including a Jenny, Set, Go commercial which used her 1991 song “Make It Happen” as well as different Conversation commercials, where she discusses the importance of health with other Jenny clients.
