Getting fit fast! Kim Kardashian opened up on Friday about how she’s planning to shed the last 20 pounds of baby weight.

“This time I think weight has come off quicker than last time because I kind of learned how to eat better,” the Keeping Up With the Kardashians star, 35, told E! News while hosting Hakkasan Las Vegas’ third anniversary party on Friday. “Last time I worked out a little bit harder. This time I’m eating differently. I’m doing the Atkins diet and I’m so militant about it that I just started working really hard and I think the mix of the two will really help out this last 20 pounds fly off. I’m praying.”

Later that night, the reality star shared a short clip via Snapchat of her and her friends going to a Jack in the Box drive-thru; though she ordered an Oreo shake for a pal, she told the drive-thru employee it wasn’t for her because “I’m on Atkins.”

Kardashian, who gave birth to son Saint West on December 5, has been documenting her progress via social media and her app ever since.

In March, the Selfish author shared with fans that she had already shed 42 pounds and wanted to lose a total of 28 more.

“It’s a challenge. It’s not easy at all,” she added Friday at the event where DJ Ruckus entertained the crowd. “We just got back from our family vacation and every day we were up early working out.”

The Kardashian-Jenner clan recently enjoyed a fun-filled ski trip together in Vail, Colorado — everyone, that is, sans Rob, who announced his engagement earlier this week.

While on vacation, the mother of two snapped several stunning shots of the scenery — a far cry from her usual selfies.
