American reality star Kim Kardashian has slammed reports that she underwent surgery to lose her pregnancy weight. A magazine report claimed she spent $80,000 on procedures to cheat her way to her defined post-baby body. It stated that she had fillers, stretch mark treatments and a fat reducing ultrasound procedure on her stomach that costs up to $5000 a session.

"I am very frustrated today seeing reports that I got surgery to lose my baby weight.This is FALSE. I worked so hard to train myself and eat healthy, I work out so hard & this was such a challenge for me but I did it!!! ," the 33-year-old Kardashian stated.

"I'm so proud of my accomplishment & NO ONE will take this away from me with fake reports! Say what u want about me but I work hard & am the most disciplined person u will ever meet," she wrote on her Twitter account.

Kardashian has maintained that Atkins diet is the secret to her post baby body.

"I've actually been doing the Atkins diet & luv it," she tweeted to a fan.

Atkins diet has several fans including Jennifer Lopez and Kate Middleton.

"Kim Kardashian wanted a balanced and effective way to lose weight following her pregnancy and she chose Atkins," Colette Heimowitz, Vice President of Nutrition for Atkins Nutritionals, Inc., told ABC News.

"She ate lots of lean proteins, veggies, fruits, and healthy fats like avocado and nuts. She experienced previous success on the plan, and knew she needed something that works," she added.
