If this stuff gives us her body, we want it!

Khloe Kardashian is the spokeswoman for Protein World, and what better way to endorse a product than to strip down into a sexy swimsuit and showcase your flawless physique?

The Revenge Body has rapidly transformed herself into the hottest K sister, but it hasn't been easy! Not only does she wake up at 5am every day to workout, but she also follows a strict diet and rarely indulges in a cheat day! With this kind of discipline, no wonder she looks so bangin'!

"I used to be someone that they would label as 'plus-size,' and f— that — I don't want to be called that! I'm a woman with curves, I'm what I would say is average-size at the time. I was very proud of who I was, and I felt so shamed ... I still don’t think I was big. I know I was bigger than I am now, but I was like, 'I am sexy and hot, and I want to be in a body-con dress and a pair of jeans,' and that was just me. I think you should be confident and comfortable in your own skin," she recently told Fortune.

We love her confidence!
