According to US Weekly, the 32-year-old singer finally decided she wanted to get back in shape after the haters unleashed their fury on her.
“A lot of people were on her about her weight and it depressed her,” her pal dished. “She went through a bad time because of the criticism.”
The What A Girl Wants singer enlisted in the Fresh Diet – a 1600-calorie-a-day delivery diet program which offers nutritious and delicious food options.
“She did it all on her own,” says an insider. “She goes online and picks out her food.”
An example of what she eats in an average day?
Pumpkin-apple quinoa oatmeal in the morning, a chopped grilled steak salad with roasted tomatoes for lunch, and a dinner of grilled ahi tuna with sweet potatoes and cauliflower, with apple-cinnamon cheesecake for dessert.
As for exercise, she has been combining weight training with Tee Sorge along with her regular yoga classes.
“She’s been working hard -- she wants to lose a bit more, but she feels great,” the pal explains. “It’s more of a mind-body thing for her. She believes in exercise that she enjoys, doing strength work as opposed to intense cardio.”
Christina isn’t the only one happy about her slimmed-body.
“Everyone on set is really happy for her,” an insider from The Voice reveals. “Show execs hope her new look will spark viewers’ interest in her again, and get people tuning in. Christina’s weight is giving her a fresh start.”
