Kim Kardashian Is Officially Back to Her Pre-Baby Weight

Congrats, Kim!

Kim Kardashian West has her pre-baby body back, five months after giving birth to her son, Saint.

The 35-year-old reality star shared a picture of herself on the scale on Friday, revealing she weighs 135 pounds -- which she previously told fans was her pre-baby weight. Kim gave credit to her Atkins diet for the impressive achievement.

"Yaaaasssssss!!!! #Atkins" Kim captioned the snap.

And she certainly has no problem showing it off. Earlier this month, Kim stepped out in New York City wearing a denim high-waist mini skirt and a tight-fitting top, highlighting her flat stomach. On Wednesday, she flaunted her toned legs in eye-catching thigh-high lace-up Tony Bianco boots.

Kim's latest weight-loss update late last month had her at 139 pounds. "YOU GUYS!!!!! PRE BABY WEIGHT WAS 135!!!!!" the mother of two excitedly shared.

The Keeping Up With the Kardashians star has made it clear that losing the baby weight from her second pregnancy was a priority this year, putting it at the top of her list when it came to her New Year's resolutions. She's also been open about gaining 60 pounds while pregnant with Saint, and wanting to lose an additional 10 pounds that she's "gained the last few years."

Kim's no stranger to the Atkins program, using it after she gave birth to daughter North in 2014. "It works for me!" she tweeted in January about her diet of choice. "So much variety on #Atkins40 and Harvest Trail Bars = YUM"

She's also, of course, been putting the work in when it comes to exercise, sometimes hilariously racing against her husband, Kanye West.
