Kim Kardashian's desire to drop down to a US size zero (UK size 4) and her extreme diet plans have left her family anxious, according to insiders.
Last week the 33-year-old reality star revelead she was desperate to lose 20lbs (1st 6lbs) and posted a picture of herself from 2009 along with the caption - "Ughhh i am 20lbs lighter here! This was just 5 years ago! Ok I'm going back on my grind I gotta get back here!" She added: "Starting diet TODAY! No carbs. Crazy workouts. Do any of u moms see their bodies just not the same? I'm not gonna call it babe weight bc thats an excuse." (sic)
An insider reveals: "Kim's obsessed with losing 20lbs and is desperate to be a size zero. She's cut out carbs and has said she'll restrict herself to 800 calories a day."
But while Kim, who shed three and a half stone following the birth of her daughter North last year, is determined to slim down pals say that her family are worried about her extreme plans.
A source reveals: "Everyone feels her new weight obsession isn't healthy and have tried to convince her she's a naturally curvy girl."
