Kim Kardashian Reveals Her Impressive Waist Size After Post-Baby Weight Loss

The reality TV star has been documenting her weight loss all over social media since welcoming Baby #2 -- and now, she's revealing her waist size in a new video.

The mother-of-two took to Snapchat earlier today during a fitting, where the man doing her measurements revealed she's a size 26. Kim, clearly happy with the number, is heard squealing in excitement.

The news comes after she announced her weight -- 132 pounds -- earlier this week. "12 pounds to go to reach 2010 Kim!" she said at the time.

She's definitely all about showing off the results of her diet, hitting the streets last night in a curve-hugging dress that highlighted her slim waist. Kardashian also posted another nude photo to Instgram this morning.

As we previously reported, the star gained 60 pounds while she was pregnant with son Saint, 5 months.

Kardashian's Atkins nutritionist, Colette Heimowitz, recently told toofab that Mrs. Kanye West slipped back to pre-baby shape with the help of a low-carb Atkins plan.

"She succeeded with Atkins with her first pregnancy and she remembered from doing it in college with her dad [Robert Kardashian], so family was there and it was familiar to her and she succeeded," she explained. "She was able to reach her weight loss goals and keep her energy up, preserve lean tissue, you know, have her appetite under control."

"She's great to work with because she is committed and very motivated which is a pleasure," the health expert continued. "As a nutritionist, you're only as good as you patient is compliant. So working with her has been a real pleasure."

"So right now Kim is eating a wide variety of foods that include proteins like fish, chicken, eggs or different kinds of meat, colorful vegetables that are high in fiber, low glycemic fruits that are high in fiber, healthy fats like nuts and avocado," she added. "The combination of high fiber, optimal protein and healthy fats really control the appetite."
