*Naomi Campbell is now giving out medical advice.

The former supermodel, 43, insists everyone should clear out their body on a regular basis and believes this can help them lead a longer life.

“I think everyone should fast at least once a week,” she told Heat magazine. “We eat so many different things; I think it’s good to clear your intestine. I think it can prolong your life.”

Naomi said she cleanses before her catwalk shows and implemented a strict diet of liquid fruit and vegetables this summer before she walked the runway at ParisHaute Couture Fashion Week.

But she can’t be bothered to prepare the drinks herself.

“No, I’m not going to do that,” she said. “There are so many places that deliver now, though.”

Naomi – whose mother, Valerie Morris, battled breast cancer – eats and drinks in “moderation” and claims seeing loved ones suffer from cancer made her think about what she consumes.

She told Heat: “I try to do everything in moderation. I don’t drink alcohol and I stopped eating pork and chicken. When people in your family have had cancer you look more closely at what you put in your body.”
