The reality star, 32, has barely been seen in public since giving birth to her and Kanye West's daughter North West last month and sources say she's determined to shed her pregnancy pounds before stepping out.
But even though she's already said to have lost 20lbs out of the 50lbs she put on, Kim's had to slow down as doctors have warned her to take it easy in the first five weeks after giving birth.
‘[She] won't leave the house until she's thinner,' an insider tells Us Weekly.
‘But Kim can't lose the weight fast enough. And she's frustrated she can't exercise yet.'
To keep motivated, Kim is believed to be focusing on how Beyoncé, 31, unveiled an amazing figure just two months after giving birth to baby Blue Ivy Carter in January 2012.
‘She really looks up to Beyoncé,' the source says.
Kim reportedly plans to show off her slimmed-down bod later this summer on mum Kris Jenner's talk show.
