LOS ANGELES (MSN)Kim Kardashian insists one can’t ‘spend life’ worrying about calorie intake. Kim works hard to maintain her enviable body, but acknowledges she’ll never have a naturally athletic shape. ‘I worked out a few years ago I was never going to be one of those skinny girls and now I’ve accepted my curvy shape, I feel so much better,’ she admitted in an interview with British magazine Closer.
