Kim Kardashian is already working on a diet to lose the weight she gained while pregnant with her daughter. Though Kardashian and boyfriend Kanye West are still in the hospital with their premature baby, Kardashian is looking forward to being able to work out again.

According to International Business Times, tabloids have predicted that Kim, who is 5'2", gained 200 pounds while pregnant. While this seems like an exaggeration, the International Business Times believes that Kim gained at least 30 pounds. Kim's goal is to return to her pre-pregnant weight, which is 115 pounds, Hollywoodlife.com reports.

"She's already looking ahead to when she can exercise again" a source told Us Weekly.

Kim is already being strict on herself.

In the hospital, Kim "has over 30 bouquets from loved ones," an insider told Us Weekly. "She told everyone not to bring sweets - she said she doesn't need any temptations!"

"She really wants to get back into shape. It's important to her," the source added.

In the earlier months of her pregnancy, Kim had a miscarriage scare and many believed it was because she was spotted at the gym almost every day.

"Kim's not respecting her pregnancy," an insider told Page Six at the time. "She's running around, working out seven days a week. She's working with two different trainers to control her weight, including Tracy Anderson and a pregnancy trainer."

Once Kim can leave from the hospital, she plans to continue her workouts with Anderson. She is also looking into hiring Gunnar Peterson, The Daily Mail reports, who helped her younger sister Khloe lose 25 pounds.

However, Kim is unable to exercise at the moment. She will stay in the hospital until her little girl, who was born five weeks premature, gains five pounds, The Mirror reports.

While Kim is working on her diet, Kanye is hard at work, The Daily Mail writes. Since the birth of his daughter, a source says Kanye has been enthusiastic to write new music.

"He's been really inspired by the birth," a source told Life & Style. "He's written four songs already."

Kanye also has a lot on his mind in terms of his music career. His newest album Yeezus was released on Tuesday.
