She's got one of the most envied bodies in the world, with millions of women dying to look just like her.

So Kim Kardashian's fans will be pleased to know that the 31-year-old reality star maintains a refreshing approach when it comes to staying in shape.

Kim revealed her diet secrets as she shared another picture of herself in a bikini on her Twitter page, showing off her toned curves in a sexy purple two-piece

Kim said in a recent interview: 'I used to eat a ton of junk food, but there are plenty of fast food places that offer healthy options, so there's no excuse for eating badly all the time.

'Although, when I go out for dinner, I eat what I want. You can't spend your life worrying about calories.'

Kim later shared another picture of herself in the bikini, with the caption: '#nofilter #nophotoshop.'

And earlier this week Kim tweeted that she was keen to tone up, writing: 'Back on my workout grind!'

Kim's bikini pictures came after she was subjected to abuse on Twitter over her weight.

After Kim received comments surrounding her figure, and the size of her derriere on the micro-blogging site, sister Khloe came forward to defend her sibling.
