Kim Kardashian shocks fans as star shows off her REAL body in rare unedited photo before drastic weight loss

KIM Kardashian showed off her unedited body in a throwback photo she shared to celebrate her friend's birthday.

The reality star, 41, has come under fire for appearing to photoshop her social media snaps.

But Kim went for the natural look in a throwback pic she shared on her Instagram Stories on Sunday.

The Kardashian mother-of-four appeared to have ditched the filter as she posed with three of her friends on the beach.

She wore a skintight khaki bodysuit and shorts, with a printed shirt tied around her waist.

The SKIMS founder displayed mild blemishes and hints of cellulite on her legs in the shot.

Meanwhile, Kim recently admitted she has lost 21lbs in just over a month, amid her family's fears that she's "the skinniest she's ever been".

Kim shocked fans last month when she dropped 16lbs in three weeks to fit into Marilyn Monroe’s iconic dress for the Met Gala.

The SKIMS founder told Vogue on the red carpet: "I tried [the dress] on and it didn't fit me. I said, 'Give me three weeks.'

"I had to lose 16 pounds down today. It was such a challenge. It was like a [movie] role. I was determined to fit [into] it. I haven't had carbs or sugar in about three weeks."

And last week, Kim admitted she has lost even more weight after sticking to the ultra-strict diet.

She said on The TODAY show: ";It actually taught me a lot about my lifestyle and my health, and since then, afterwards, I continued to eat really healthy.

"I mean, I'm down 21 pounds now. I'm not trying to lose any more weight, but I have more energy than ever.

FEARS FOR KIM

Meanwhile, The Sun exclusively revealed that Kim's family is concerned she's losing too much weight and is "barely sleeping".

She has admitted her packed schedule of filming the family’s reality show, studying to become a lawyer, looking after her four children and her bi-coastal romance with Saturday Night Live star Pete Davidson has taken its toll.

“Kim looks amazing, always, but she’s good at keeping how stressed she is hidden,” an insider tells The Sun. 

“She's the skinniest she's ever been and barely sleeping. Her family knows that a lot of this is her rebounding from a very controlling marriage, and her determination to show Kanye how much better she is doing without him.

“But whereas before she was incredibly healthy and well-rested, now she's constantly jetlagged and she’s finding it hard to fit workouts in. I think Kim’s really struggling but won't admit it. 

"She is having a great time with Pete but the travel is taking its toll and she’s barely sleeping. Everyone is worried she’s burnt-out.”
