Kim Kardashian is showing off her post-baby body for the first time since giving birth to daughter North West four months ago. Although she’s been more comfortable wearing tighter clothes lately following shedding more pounds, she hasn’t shown off a revealing photo until now.

Kardashian, 32, posted the photo to Instagram with the caption #NoFilter.

Her boyfriend, Kanye West, liked it so much that he commented on Twitter, writing “HEADING HOME NOW.”

On Sunday, Kardashian told one of her Twitter followers she was using the Atkins diet to shed the baby weight. "I've actually been doing the Atkins diet & luv it,” she wrote, Daily News reports.

A spokesperson for Atkins confirmed it, saying After she delivered her baby on June 15, she wanted an effective and balance way to lose the baby weight.

She’d done Atkins before and knew it worked, so once she got the approval of her doctor, we connected her with our Vice President of Nutrition Colette Heimowitz, who counseled her directly.”

Back when the Keeping Up with the Kardashians star was still pregnant, she did a maternity photoshoot and explained that West has taught her a lot about “privacy.”

“I'm ready to be a little less open about some things, like my relationships. I'm realizing everyone doesn't need to know everything. I'm shifting my priorities,” she told DuJor.
