Mariah Carey's Balanced Diet

Mariah Carey refuses to mix her proteins and carbohydrates.

The 'Hero' singer admits she has to watch her diet and is careful to balance out her food groups, as well as undertaking regular exercise.

She said: "My diet consists of not a lot of oil or butter and eating starch separate from protein - so if I have rice, I can't have meat at the same time. I also do water aerobics, swimming and Pilates."

Mariah also says she has learned to accept her curvy body as she will never be able to slim to a size zero.

She said: "I think people should be whatever size they naturally are. I'm happy at the size I'm at now. And size zero? That's never been a reality for me because of my butt and boobs.

"A size zero is not really healthy, unless it's natural for someone's body type. But to starve oneself to obtain that, that's just not realistic. It'd be nice if society could just embrace all body types, but clearly we can't."
