"In the beginning, they sent me so much food and I was traveling with suitcases of Nutrisystem," Janet said. "I would bring my suitcase of food while I'm in hair and make up." Now that's dedication.

Janet also explained how Nutrisystem's simplicity and effectiveness are some of the reasons why she's happy to attach her name to their brand. Having dealt with weight struggles herself, which she expounds on in her book True You, Janet's use of the weight loss program has been a staple in her hectic lifestyle.

"It doesn't just teach you how to lose weight but how to lose the weight and maintain it, and that's always been an issue for me," Janet said. "It fits perfectly into my lifestyle being so busy, always on the go."
