As the 'Keeping Up With The Kardashians' star Kylie Jenner continues to grow up and discover a lot of things about herself, the reality star recently shared her latest discovery about her health after gaining weight and how she's more sensitive now about what she eats.

As the stylish Jenner who just recently launched her newest Kylie Hair Kouture extension line at the Bellami Beauty Bar shared that she indeed gained weight this year and in her efforts to lose the weight, she discovered something about her body for the first time.

"I'm working out and I'm eating a lot better," she said after previously sharing that she gained 15 lbs. to be exact. "Well, I didn't realize I was lactose intolerant. I just became lactose intolerant like, this year," Jenner revealed of her latest discovery.

Apparently, being Lactose intolerant isn't really good news for the fashionista. "And I love like, cheese and everything so I'm so mad but, I dunno, I just, it was my year to eat bad. I was like, while I'm young, I might as well. I didn't care about a diet or anything. But now, this last month, I've been working on it just for health reasons only," she continued.

And so, now that Jenner decided to finally start getting serious in taking care of her health and wellness, she revealed that it is her really close older sister Khloe Kardashian that inspired her to go back to the gym.

And not only that, Kardashian herself found out as well something new about herself. "She actually found out, which is interesting-I don't know if she wants me to tell people this, that she was allergic to coconut oil and she was cooking everything with coconut oil," Jenner revealed of her sister Kardashian adding, "So then she stopped that and then she like, lost all the water weight. She she's doing really great."
