A WOMAN who is 5ft 10in and weighs 175lbs has shared how trolls often "mansplain" BMI to her – but her fans say she looks incredible.
The TikTok gym girl and online coach showed off her figure to prove that BMI is "not an accurate measurement".
In a video, Sierra (@sierraaudet) donned a cross-back sports bra and cycling shorts to prove that numbers don't mean anything.
"A reminder that BMI is not an accurate measurement. My weight is 175lbs and it says I'm overweight but this is what I look like," she captioned the post.
Body Mass Index is a person's weight divided by the square of height, where a high BMI can indicate high levels of body fat.
The gym goer from Vancouver revealed that she's 175 pounds and almost five-foot-ten, and even though her BMI classed her as overweight, she looks and feels great.
But this doesn't come without the constant "mansplaining" of BMI from random men in her comment sections.
One man wrote: "You should let it do by a doctor it's obvious that you can't make up your BMI by only weight, height and age," to which Sierra replied: "That's literally what bmi is".
Another troll said: "If you want attention just say so".
A third "mansplainer" commented: "BMI is accurate for 95% of people who don't lift in a serious manner. We've known this since before I was born".
