Move over Kim and Kourtney, your big sis is single and raring to go back out on the open market judging from by her super fit appearance. The Keeping Up With The Kardashian's star (thanks, Ryan Seacrest) seems determined to move on from her estranged husband, drug addicted former NBA star Lamar Odom, once and for all.

So how much weight did KK lose and was it the result of hard work or a secret concoction of pills and Hollywood diet secrecy? The total weight loss came out to be an impressive 30 pounds. But she's not resting on her laurels.

Just check out this daring instagram selfie that only a Kardashian could pull off. It's Khloé on the east coast wearing a captain's hat and sexy, black one piece swimsuit. But could Khloé's recent fitness push by the result of constant ridicule and an over-bearing mother?

"She didn't mean harm, but when I was around nine I overheard my mom [Kris Jenner] telling her friend I needed a nose job," Khloé told Cosmopolitan. "I was shocked. I hadn't even thought about it. I've grown into my face but I've had makeup artists tell me, "You should get a nose job"

Harsh! Just knowing that a mother would would want their daughter to have non-essential plastic surgery is shameless at best and degrading at worst.

But in today's media driven world you need to look your 'best' at all times, lest you let the people who built you up consequently tear you down. This is all very weird and ironic all at the same time no?

But Khloé isn't the only one in her famously beautiful brood in dire need of losing weight. Her brother Rob has set out to lose 70 or so pounds. He's been hitting the gym and eating right under strict guidance from a nutrionist. A health scare prompted the turnaround.

And the most famous Kardashain of them all, Kim, has an excess 50 pounds that she'd love to get rid of ASAP. But on the other hand she has a great excuse, unlike Rob, when it comes to her significant weight gain. She was pregnant with Kanye West's Baby North after all! It can't hurt for a nursing momma to gain some weight. North needed sustenance after all.

In total, 150 pounds of Kardashian will never be seen again.
