Jenny Craig, one of the world's leading authorities on weight management, announced Mariah as their new Brand Ambassador in 2011. Mariah started on Jenny in late July following the birth of her twins, and is taking this public journey to shine a spotlight on the importance of maintaining a healthy, active lifestyle. “I'm just here as a catalyst. Ideally this will help create awareness — my goal is to at least make a difference,” she said.
Mariah also served as Jenny's lead Brand Ambassador throughout the American Heart Association's My Heart. My Life. initiative to encourage and inspire others to live healthy, happy, active lives. “I feel like Jenny and the American Heart Association together is the beginning of a world class alliance. An alliance that can help change things for the better,” Mariah said. “As an artist, I use my voice to entertain. But, today I want to use my voice to draw attention to a serious matter. Two-thirds of the country is placing themselves at risk for heart disease and diabetes. Largely, that is due to unhealthy eating patterns and lack of physical activity. I obtained a greater understanding of this when I was pregnant with my twins and dealing with my own health issues. That's why I feel so strongly about working with Jenny and the American Heart Association to help Americans get serious about their health as it pertains to these issues which are so important.”
