Kardashian West tells C Magazine in a new interview that her reluctance to smile stems from her first pregnancy in 2013 with daughter North West.
The reality star, 34, says preeclampsia caused her to bloat, and in turn set her up for harsh critique from the public.
"Last time [contributed to] not only the weight, but also the swelling that everyone would make fun of, not understanding that I had this condition," she tells Amanda de Cadenet in the magazine's 10th anniversary cover story.
The expecting mom calls the body-shaming the "worst."
"I couldn't help it, and everyone would say, 'She can't stop eating,' " she says. "I delivered at 180, and they were like, 'She's 210 pounds. She's getting dumped because she's too fat' and all these ridiculous stories. It really took a toll after the fact, when I was losing weight. I gained 50 pounds, and it's tough to get it off."
Kardashian West, whose husband Kanye West is also known for his reluctance to grin, says she was "dedicated" to getting back to her pre-baby shape, but it "changed the way I viewed wanting my picture taken."
"Before I was always smiling, and so into being out and about," she tells the magazine. "After I had the baby, I was like, 'These are the same people that made fun of me, and posted the stories that were so awful, calling me fat for something I couldn't control.'"
Her solution? No more smiling.
"'I don't want to smile for them. I don't want to be out,'" Kardashian West says. "Even if I was more confident, I just didn't feel like being that girl who was going to be smiling for every photo. It changed my mood; it changed who I was; it changed my personality a lot."

The star also opens up about her struggle to conceive in the interview.
"It was a long road. I would go to the doctor in Beverly Hills every day at five in the morning to get tested to see if I was ovulating," she says.
