Mariah Carey loves flaunting her figure in low-cut, tight-fitting ensembles — and with her body, who could blame her? But the diva says it doesn’t come easy.

“It’s really hard,” Carey tells E! News of her strict healthy eating habits. “My diet … you would hate it.”

The singer jokes that she mainly eats only two foods.

“All I eat is Norwegian salmon and capers every day,” says Carey with a laugh. “That’s it!”

While her diet may not be that strict, Carey does say she definitely watches what she eats.

“I try to stick with the proteins,” she says. “It’s the worst.”

The singer has spoken about her emphasis on a healthy diet for achieving her physique in the past.

“I realize that 90 percent of losing weight is my diet,” she previously told Shape magazine.

“Today my workout routine is more about getting and staying toned,” she said at the time. “And for me, that means either taking hour-long walks a few times a week or jumping in the pool three or four days a week to do 45 minutes of aquatic exercises.”
