Osbourne admits that changing her eating habits and exercising has helped her maintain her weight. It has become something that she "really enjoys" doing. By adding variety in her workout routine, which consists of incorporates cardio, circuit training, yoga and Pilates, there is never a dull moment.

"[Working out] is something I really enjoy doing," Osbourne told the weekly magazine. "I never thought I'd be that kind of girl. I do up to half an hour of cardio, and I also do circuit training, yoga or Pilates - I mix it up."

Osbourne shared that she allows herself one cheat a week (pizza) but her overall food choices are better and consistent. "For breakfast, I will eat either cereal or a little omelet thingy made with egg whites, mushrooms and spinach. Lunch is usually a salad or a turkey burger. And then for dinner, I'll have brown rice with vegetables and some kind of meat."

"Never deprive yourself of anything, because then you get angry about it," she said. "People who are hungry are miserable."
