Kim Kardashian and sister, Khloe Kardashian are finding out that public sentiment is a fickle thing.


Though there was a time when the roles were flipped, now it's Kim catching criticism about her appearance in terms of fashion and weight gain while Khloe makes the rounds as a cover girl following a substantial weight loss.


How did Khloe shed so much weight?


“Everything in moderation,” Khloé said. “Right now, I try to go on hikes or something. I work out at least four to five days a week.”


Khloe went on to talk a little bit about the struggle she's endured ever since she was young in regards to having Kim and Kourtney as sisters. 


“When I was a chunky little 8-year-old and I had these two beautiful sisters [Kim and Kourtney Kardashian], I’d wonder, why don’t I look like that?” she said. “I hate it when people compare me to my sisters…I will never look like them.”


Obviously, this is in contrast to Kim's advancing pregnancy and changing body which has made for an easy transition.


A source says, “[Kim] was always seen as the sexy one in the family, and she loved it. Now that she’s gaining so much weight, Kim isn’t confident about her body. It makes matters worse that Khloé is looking amazing. It’s hard for Kim to be happy for her.”
