The fitness influencer used to have breast implants, but she had them removed last year due to breast implant illness.


After a decade of unexplained, autoimmune disease-like symptoms, Diary of a Fit Mommy's Sia Cooper had her breast implants removed.

Following her explant surgery, Cooper has been open about how the experience affected her. She's been candid about dealing with weight fluctuation, and she's shared multiple before-and-after photos on social media.

It's clear that Cooper has a healthy body image these days. However, she still deals with the occasional troll. Most recently, she clapped back at a man who criticized her "flat chest."

The troll told Cooper that "flat chests were meant for middle school" and that a "real woman" should have a "grown-up body," she wrote in an Instagram post.

Understandably, Cooper blocked the troll. But apparently, he used his other social media accounts to continue berating her. He told Cooper that her body "looked like that of a young boy," she explained.

"You know what? My body and my natural breasts are not here for YOUR entertainment," Cooper wrote. "If you're a man and you're here for this reason, you're barking up the wrong tree."

The fitness influencer went on to say that it was because of men like this that she "felt pressured into getting breast implants in the first place."

"Now, I don't give a damn how small my breasts are because at the end of the day, I've been at both ends of the spectrum and I have never been happier to go back 'small,'" she said.

Cooper previously reflected on the connection between femininity and breast size in an April Instagram post. She admitted that one of her initial reasons for getting implants was "to feel feminine."

"I want you to know something, though. Boobs—no matter what size you are—saggy or not, do not make you any more or less feminine of a woman," she wrote in her April post. "It's all about what's inside of you, as cheesy and cliche as that might sound. I've never felt more confident than I do now. Confidence isn't something that you can buy in stores or in a doctor's office. It finally comes when you make peace with who you are and what you've got to offer."

Today, Cooper says she has "more important things to worry about" than her breast size—let alone a troll who has the audacity to criticize her body.

"I am living MY best life," she wrote in her most recent post, alongside a clapping emoji. "Emphasis on MY."
