Looks like Kourtney Kardashian has lost all her baby weight — and then some! In fact, the eldest Kardashian sister only weighs a few dozen pounds more than her oldest child, Mason Disick, according to a deleted scene from Keeping Up With the Kardashians.

As the scene starts, Kourtney and sister Khloé Kardashian are hanging out at the Khloé's house along with their friends Simon Gebrelul and Savas Oguz, and Kourtney is preparing herself a post-workout salad.

"I went running," Kourt says. "I had to run inside so fast because I was scared to, like, melt."

Those fears might not be unfounded! Khloé revealed her sister's weight is down to the double digits. "You know she's 97 pounds?" she tells their friends.

"Guess what?" Kourtney interjects. "I'm 98. I gained a pound. I'm 98."

Then the 38-year-old reveals she's not much heavier than her eight-year-old son. "You know Mason is 62?" she asks.

In April 2015, Kourtney posted an Instagram pic of her bathroom scale reading 116 pounds, and even then, she seemed self-conscious about possible backlash. "I'm 5 feet tall, so everyone relax," she wrote in the caption. "I'm on a workout kick, trying to bring some Monday motivation."

If you think Kourtney's weight sounds scary low, take heart. The National Institutes of Health says the normal weight range for someone 5 feet tall is 97 to 127 pounds.

On the other hand, if you're inspired by this reality star's weight loss, she recently revealed the rules of her diet on her website.

"I always try to avoid sugar — especially refined sugar — for so many reasons," she said. "First, sugar is addictive and I notice that after I eat it, I need it. Sugar doesn't sustain you when you actually need energy, like for a workout. Also, when I eat sugar, I find that more cellulite appears."

Gluten and dairy are out of the question, too, said Kourt. "I have noticed a great positive change in behavior with my children when we stick to a gluten-free and dairy-free diet."

We're not sure we could ever be so disciplined. This is one Kardashian who's tough to keep up with!
