Mariah says the most important part of her new, healthier lifestyle is her diet. Patricia tries to cook Mariah's food without using oil and butter. She's also helped her stop snacking.
When Patricia told Mariah to cut mac 'n' cheese out of her diet, Mariah says the news broke her heart. "That's the thing that I have difficulty letting go of because that's comfort food," she says.
Instead, Patricia incorporates lean protein and lots of veggies into Mariah's meals. On a typical night, she prepares foods like artichoke hearts with cherry tomatoes, steamed zucchini and chicken marinated with lemon and soy sauce.
On occasion, Mariah allows herself to have one or two bites of her favorite foods—something she calls her "morsel diet."
Since making the commitment to eat healthier and get in shape, Mariah says she's gotten down to the same jean size she wore in 10th grade. "For me, it's not about a number on a scale," she says. "It's not about necessarily even a size. It's about feeling good and being comfortable in your own skin. Right now, I feel really great. I feel better than I've ever felt."
