Khloé Kardashian, 40, learns her biological age after confessing bad eating habits

Khloé Kardashian learned important news about her health during the Season 5 finale of “The Kardashians.”

The 40-year-old underwent testing to find out her biological age with Kris Jenner, Kim Kardashian and Scott Disick on Thursday’s episode.

“I honestly feel like all of my sisters would be younger,” Khloé said in a confessional, noting that her oldest sibling, Kourtney Kardashian, “works out” and “eats great.”

On the flip side, Khloé acknowledged that she isn’t a healthy eater.

“I love ice cream. Cookies and Goldfish. Wheat Thins. Cereal. Love it,” she said.

Khloé, Kris, Kim, and Scott found out their test results from a doctor on a video call.

First up was Kris, 68, who learned her biological age is six years younger. Next, Kim, 43, was elated to be told her biological age is 34.

But the good news only made Khloé more anxious to get her own results.

“I’m nervous. The pressure of you being 34!” she told Kim.

In a confessional, Khloé confessed, “My heart is racing. I feel my pulse beating out of my neck. Why am I so freaked out? If I find out I’m 812, I’m just gonna cry. I can’t do this.”

The mom-of-two , who was 39 at the time the episode filmed, found out her biological age is 28 — and she went absolutely nuts hearing that.

Khloé jumped up and down and screamed so loud, to the point where Kris joked she lost her hearing.

“Never in a million years! If I had to bet money, I would’ve never bet on myself,” Khloé said in a confessional. “Kim is livid, by the way. I know she’s pissed.”

Kim was indeed livid about her sister’s results.

“For sure I’m pissed,” the SKIMS founder told viewers. “I always wanna be the highest achiever.”

To make things even better for Khloé, the doctor told her that her pace of aging is .72 – making her the seventh slowest-aging person in the world.

“The world needs to know that me, the fat one, is now better than the best one,” Khloé said in reference to Kim.

“My tagline on ‘Keeping Up’ was, ‘I’m the fat funny sister,’ if you look at the opening of the show,” she recalled. “The fat funny sister is 12 years older than her chronological age.”

The former “Revenge Body” star said while she “hated” taking the biological test at first, she’s happy she did it after getting the results.

“This is the best I’ve ever taken in my f–king life. If its not broke, don’t fix it,” she said, joking, “The kid’s menu coming right up! Pizza!”

“No I’m not gonna change,” Khloé added. “And let me tell you, this is not even my prime. Give me a couple years when I’m zen, and let me take this test again.”

Khloé opened up about her health on the wellness podcast “SheMD” in May, noting that she “used to be overweight a lot of my life.”

“It took years for me. I’ve always been chubby — like athletic. I’ve always played sports. I just was never in shape,” she explained, admitting that she “used to be a major emotional eater.”

“And then I would cry and probably do it again because I was sad so I needed the ice cream again,” the reality star recalled. “And it was this crazy repeat cycle, but I gave myself a lot of patience and I just took my time.”

On the July 11 episode of her Hulu show , Khloé admitted she would’ve tried Ozempic when she was on her weight loss journey.

“I tried any other thing. I tried any fad weight loss trend except for the real thing that actually works. And that is a lifestyle change,” she said.
