The 34-year-old previously opened up about her struggle to lose weight after the birth of her one-year-old daughter North West.

It seems Kim still isn’t happy – despite posing naked for Paper magazine last year – judging by her latest throwback.

Sharing a photo of her with her 35-year-old sister, Kim wrote: “Since it’s award season I will do my #TBT to the time Kourtney and I went to the Emmys. She was pregnant and I was about 15 to 20 pounds thinner.”

Last year Kim revealed she still hasn’t reached her goal post-pregnancy weight.

She told Grazia: “I’ve lost a little bit but I feel like I’m gaining it back. It’s hard.

“A couple of years ago the scales said I was 20lbs thinner than I am now, but after you have a baby your body changes. But it’s been a year so I have no more excuses. If I could lose 10lbs it would be ideal.”

Kim’s obsession with her weight is reportedly even putting her in doubt as to whether she wants to carry another child.

She and husband Kanye West, 37, want another child, but Kim is allegedly concerned about the effect it will have on her body.

A source told Radar: “Kim will use a surrogate because she doesn’t want to have huge weight gain as she did while pregnant with North.

“Having worked very hard to get her famous body back into shape, Kim is afraid of being unable to do it again.”
