London - Kim Kardashian says her toned figure requires “dedication”.

The 'Keeping Up with the Kardashians' star has regained her slender frame since giving birth to daughter North - her first child with fiance Kanye West - last June and credits a carbohydrate-free diet and regular workouts with getting her body back.

The reality TV star is clearly proud of the progress she has made, as she posted a picture of herself with friend Blac Chyna on Instagram, showing off their physiques. The caption read: ‘Getting right for the new year'.

The snap received over 500 000 likes, with one fan, thomamorgaan, declaring: “This is my new asspiration”, with sherellemyers adding: "bootybootybootybooty rockin it around!! HOT!".

Some fans were bemused by the pics, with homegurlb making a simple plea: ”Please stop”, and razooona66 saying “Btw it's not sexy pic (sic)”. A follower on Blac Chyna's Instagram page, jasminehopster, said: "umm no chynas looks horrible. Her shots obviously were done right. You're a hater if you say kims doesn't look better. Real or fake. Hell hers is prob fake too at least it looks good (sic)".

Some believed the picture was manipulated, pointing out the tell-tale signs. "Pictures are photoshopped. U can see curves on the door.. On Both pictures," said oddnela, with many in agreement with her observation.

Kardashian should be used to the criticism, as her post-pregnancy sexy selfie of October 2013 had also received scathing comments from many followers. Both the Daily Mail and RadarOnline’s websites were inundated with comments and messages describing the reality TV star as “nasty”, “disgusting”, and looking “nauseatingly huge”.

Asked by TMZ for her secret to looking good, she said: “no carbs, work out, dedication”.

Responding to a fan's question about her wishes for in 2014 on, Kim wrote: “I want to stay healthy and get in better shape for 2014!”

The brunette beauty recently admitted she gained a lot of weight when she was pregnant because of her cravings.

Asked for her cravings, she said: “mostly cheese, chilli cheese fries, everything w cheese. (sic)”

After North's birth, the reality TV star embarked on a strict diet and weight loss regime, and has continued to eat healthily, but admits she still has a soft spot for her favourite sweet treat.

She added: “Krispy Kreme donughts....don't tempt me, I'm doing good right now lol (sic)”

Kim suffered from the condition preeclampsia while pregnant, which caused her body to swell, and made it a difficult time.

She wrote: “When i was pregnant it was hard. my face shape changed, my body changed and nothing in the tabloids were going to be nice. it was a negtive time (sic)” - Bang Showbiz and IOL
