See More Celebrity Post-Baby Bods

Kim Kardashian has already dropped some serious weight!

The "Keeping Up With the Kardashians" star showed off her slim post-baby bod in Los Angeles on Wednesday, putting her curves on full display in a nude jumpsuit, green utility jacket and clear lucite heels. She completed her cleavage-baring ensemble with a braided ponytail, dark shades and a Birkin bag.

The mother-of-two, who welcomed baby Saint in December, has been working hard to get her pre-baby bod back.

The 35-year-old star signed on with Atkins as their new Brand Ambassador for the Atkins 40: Low Carb Diet Plan.

"I'm so excited! I'm 30 lbs down today but 40 to go! I'm so focused. I will show u guys my workouts on my app & share my Atkins plan too," she tweeted in January. "I gained 60lbs during my pregnancy but have been an extra 10 lbs up for the last few years so it's time to really get to my goal."

"This is going to be soooo f--king hard but I can do it and I can't wait to share it all with you! #BeastMode #WhosWithMe?!?!?!" she added.

Kim's Atkins nutritionist, Colette Heimowitz, recently explained how she's transformed her client's diet and exercise plan.

Along with the mostly protein-and-vegetable-heavy diet, Heimowitz told "Extra" that Mrs. Kanye West can snack on low glycemic fruits like berries, and get healthy fats from Greek yogurt, small portions of cheese, and nuts and olive oil.

"She's also exercising, so she'll sculpt her body with a personal trainer and lose 40 lbs. of fat with us, and if it's two to 3 lbs. a week it will take a couple months," she declared.

It looks like Kim is well on her way -- keep up the good work!
