While Khloé Kardashian has shed a lot of weight, she still feels just as confident as before.

The concept of weight loss making you happier has been linked for decades, and while Kardashian recently admitted that she feels more confident now, she hasn't seen a huge change in her attitude.

"I've always been very confident," Kardashian told People in a new interview. "I was definitely at a place of good self-esteem to begin with, thank god. But I definitely feel more confident now, I feel sexier in my body. I'm not as embarrassed if my girlfriends have a pool party, and I say I left my suit at home."

Kardashian has slimmed down considerably in recent years, and one trick she's used is getting rid of her scale.

"I don't care how much I weigh. I don't really care what size I am in clothes," Kardashian explained. "I care about how I look and feel, and am I able to run up that hill, or can I get up the stairs without huffing and puffing. I have girlfriends who are skinnier than I am, but I can sprint up a flight of stairs but they're out of breath. So for me, that's more of a rewarding feeling than seeing anything on the scale."

Of course, it wasn't always easy feeling confident, with sisters like Kim and Kourtney Kardashian, who have always been smaller in stature than Khloé, who is 5'10". Khloé admitted that being a teenager was difficult at times because of her smaller sisters, and discussed how it's counter intuitive to focus on numbers.

"They'd always be like, 'Oh, I weigh 102 lbs.,' and whatever, and that's good for them, but I would look at the scale and be like 'Oh god' because I weigh 140 or something. As a teenager, you're not understanding and knowing that difference," Khloé said. "There's so many different elements to why I weigh more. And I do think that really hinders children and those numbers are not good to focus on."

The reality star is now partnering with the fitness supplement Protein World, which she uses after working out to help "feed" her muscles.
