The 30-year-old beauty - who is renowned for her curvy figure - admits there is little she would leave on her plate apart from peas, which she used to pretend to enjoy as a child but now will not touch.
She said: "It`s like a family rule: The table must be filled with tons of yummy food at every gathering. I`ll eat just about anything you put in front of me - except peas.
"When we were growing up, my parents would make us finish our vegetables or we`d lose our playtime, so I had to get creative. One night, I found out that I could spit the peas into a glass of milk and they`d disappear!"
However, her trickery meant she had to volunteer to clean up afterwards so no one would know she hadn`t eaten them.
She added to Every Day with Rachael Ray magazine: "The only consequence was that I had to volunteer to do the dishes so no one would know my trick."
Despite her love of food, Kim is thought to be on a wedding diet ahead of her marriage to basketball star Kris Humphries on August 20.
When one of Kim`s twitter followers tweeted her last month saying, "On my way to GNC to buy some quicktrim", Kim responded by writing, "Take some for me! I-m about to start again! Wedding slimdown (sic)"
