Responding to a fan's question about her wishes for in 2014 on MobioINsider.com, Kim wrote: ''I want to stay healthy and get in better shape for 2014!''

The brunette beauty recently admitted she gained a lot of weight when she was pregnant because of her cravings.

Asked for her cravings, she said: ''mostly cheese, chilli cheese fries, everything w cheese. (sic)''

After North's birth, the reality TV star embarked on a strict diet and weight loss regime, and has continued to eat healthily, but admits she still has a soft spot for her favourite sweet treat.

She added: ''Krispy Kreme donughts....don't tempt me, I'm doing good right now lol (sic)''

Kim suffered from the condition preeclampsia while pregnant, which caused her body to swell, and made it a difficult time.

She wrote: ''When i was pregnant it was hard. my face shape changed, my body changed and nothing in the tabloids were going to be nice. it was a negtive time (sic)''
