But's according to the 31-year-old, that's always been the case. In the cover story for Shape magazine's newest issue, the youngest Kardashian sister admitted she's always loved her shape.
“I love my shape because I’ve earned every curve. I work hard in the gym to get it. But I also loved my shape before, when I was even curvier. I was always incredibly comfortable in my skin," she told the magazine. "Everybody else saw me in a different way, but I didn’t see myself that way."
She added, "I feel empowered and badass that I was able to accomplish everything I have."
Kardashian expressed her excitement for the spread with a cheeky tweet, a nod to everyone who considered her "the fat one" of the Kardashian family.
Despite her pride, though, Kardashian did admit that she thought the magazine could have picked a better cover photo.
(Let's be real, Khlo, you look amazing in every shot -- "simple" or not.)
The reality TV star really started getting into a fitness routine after her breakup with her husband, basketball player Lamar Odom. For her, going to the gym is like therapy.
"When Lamar and I broke up, I had all these emotions that I didn’t know what to do with. Some people suggested therapy, but instead I joined my local Equinox gym, where I’d get on an elliptical and watch bad reality TV," she explained. "As a result, I started losing weight. Once I realized I could shed some pounds that way, I began working out regularly with my trainer, Gunnar Peterson, and I made a commitment to get healthy."
These days, Kardashian says working out "takes all the anxiety away when I’m overwhelmed or stressed out."
And seeing as she's a reality star who's always on camera, Kardashian likes to keep herself looking picture-perfect at the gym. It's all about being inspired.
"When I look good at the gym, I’m inspired to do an extra squat or an extra lunge. Just because you’re going to work out, you don’t have to look like a slob," she said. "I also always wear hoop earrings; they’re like my security blanket. People laugh at me, but why not? They make me feel more dressed up. I also wear makeup when I work out [...] why should anybody else care?”
You do you, Khloe.
