Kim Kardashian is desperate to get back to her pre-pregnancy weight as soon as possible.
The 32-year-old reality TV star, who delivered her first daughter, North, naturally on 15 June, is reportedly on a strict diet and exercising with her personal trainer daily in a bid to lose as much weight as possible before she steps out in public for the first time since giving birth.
A source close to the Keeping Up with the Kardashians star told In Touch magazine the brunette beauty "wouldn't stop talking about her body" in the delivery room and "she kept asking her sisters if she looked smaller and skinnier after giving birth".
The source added, "Kim is obsessed with getting the baby weight off ? and fast.
"She really believes she can lose the first 30 pounds [about 14 kg] in the first month. She wants to look good in a bikini by the end of the summer.
"She got so big. So now she wants to look as hot as possible."
Despite working with celebrity trainer Tracy Anderson throughout her pregnancy, Kim is worried her body will never look the same again.
The source explained, "She's terrified she will never get her body back. Everyone has told her not to stress ? that it's about being healthy and having a good mind-set for your baby, not about losing the weight right away. But her family knows that at the end of the day, Kim will do what Kim wants."
Another insider claimed Kim also feels under pressure to get in shape from her boyfriend, Kanye West (36). The source said, "He's not happy about how much weight she gained ? and said it's her job to get rid of it quickly."
