Losing weight is my biggest struggle: Khloe Kardashian

With two svelte sisters, who won't be conscious? Reality TV star Khloe Kardashian, who is much broader than her sisters Kim and Kourtney, says losing weight has become her lifelong battle.

"My weight is always going up and down. I'm always fighting that. I feel like no matter what I do, I never look good enough to everybody else," Khloe has been quoted as saying by dailymail.co.uk.

The 26-year-old star has posted a video blog on her website, where she has spoken of her dilemma.

The Keeping Up With The Kardashians star often wears dresses that drape over her figure and has recently been accused of having a baby bump. At the People's Choice Awards, she sparked pregnancy buzz when she chose a floor-length, concealing voluminous gown.

"I think my weight is my biggest lifetime struggle. It's not the biggest thing in life, but it does get you down sometimes," she said.

This isn't the first time Khloe has been forced to deny she is expecting.

She made headlines in June last year when she told journalists - "I'm not pregnant, just fat!"
