Kim Kardashian and Khloe Kardashian are rocking their best bodies yet.

But a source told In Touch Weekly that the sisters did not lose their unwanted weight naturally. Instead, both Kim and Khloe underwent surgery to help aid with their weight loss.

The source said that Khloe got sick and tired of being dubbed as the “fat sister” so she took matters into her own hands and vowed to never be on the heavy side again.

Now, True Thompson’s mom seems like the thinnest member of the Kardashian-Jenner clan next to Kendall Jenner.

And when Khloe graced the FYC event for The Kardashians on June 15, all eyes were reportedly on her.

“Khloe’s outfit was backless and you could see her bones,” the source said.

As for Kim, the reality TV star also lost a considerable amount of weight. And fans were surprised when she shared a photo of herself in a bikini because her waist looked extra-slim.

“It’s amazing how skinny she and Khloe have gotten. And it seemed to happen so quickly. Of course, they insist their body transformations are the result of a strict diet and a very tense exercise routine, but some people believe both secretly got a little extra help in order to achieve the ultimate results,” the source said.

According to the source, Kim and Khloe typically get upset when other people accuse them of undergoing plastic surgery. But regardless of how many times they deny the claims, it’s obvious that they allegedly did.

“Khloe has copped to a nose job and Kim, of course, has been accused of getting butt implants, although she’s denied it. So, it would be surprising if they opted for the quick-fix route and turned to surgery to achieve their lowest weight ever. But when will it end? They’re skin and bones. It doesn’t look good,” the source said.

However, it is important to note that Kim and Khloe have very active lifestyles. In fact, the sisters have been seen working out in recent episodes of The Kardashians as well as in Keeping Up With the Kardashians.

Not to mention, the sisters also eat healthily. So, it shouldn’t come as a surprise that they have lost a considerable amount of weight.

As such, it is important to note that the tabloid is just speculating on the possibility that Kim and Khloe might have gone under the knife. But this doesn’t mean that they are correct in thinking this way.
