Khloé Kardashian knows all too well what it's like to lose and gain weight — but now that she has rock-hard abs, she feels better than ever.

"I've worked really hard because I used to be overweight a lot of my life....I've always been even chubby like athletic. I've always played sports. I just was never in shape. My thing is more the food because I have the determination. So I had to retrain my mind as to what I could eat, what I couldn't eat. I did every diet under the sun when I was younger, but now I work out five days a week. I do cardiovascular intervals with weightlifting....But now that I'm in a good place body-wise that I like, I do sort of eat what I want, but because my brain is so trained, you don't even want half of the c--- or junk," the reality star, 39, said on the "SHE MD" podcast, hosted by Mary Alice Haney and board-certified OBGYN, Dr. Thais Aliabadi.

"Or if you do want something like pizza is my weakness. But now that I am in this different state of my mind, I'm never going to eat a full pizza, but it's retraining your brain. If your brain isn't trained with your body, then you're not doing anything...When I got pregnant with True, I was 204 pounds when I delivered and I was like, 'How am I going to do this again?' Because I took so many years to do it the first time. But because I had all the tools in my toolbox, I knew what to do and I actually lost my pregnancy weight so much faster than I ever did my regular fat weight," she said of dealing with gaining weight amid her first pregnancy.

Last year, the Good American co-founder got candid about her self-esteem journey during an episode of The Kardashians.

"I had the most confidence. I was chubby, in a skintight dress, you couldn't tell me otherwise. Societygave me insecurities," she said in a confessional interview.

"I've been torn apart the minute that I've gone on TV. I didn't look like my sisters, so therefore, it's not good enough," she continued. "Then when I started, whatever, changing my look, you get better makeup, you do fillers, you do whatever, I had a nose job, and there's still people constantly bullying you."
