Janet Jackson has been unveiled as the new face of Nutrisystem home delivery weight-loss programme.

She fronts the brand's new Success initiative, starring in a national ad campaign to debut before the end of the year, showcasing her weight loss journey. The singer has also co-founded Nutribank, a new philanthropic effort dedicated to promoting nutrition and solving hunger around the world. For every pound lost on Nutrisystem in 2012, the company will match it with one dollar’s worth of food to be delivered through NutriBank to those in need.
