"I'm healthy AF. And yet my BMI places me squarely in the 'obese' category."

At 5-foot-9 Katie Karlson weighs 200 pounds. By most definitions, she is considered obese, but her lifestyle says otherwise. In a powerful Instagram post, the body-positive blogger explained how she's worked out at least four days a week for the past six years. Not only that, but she's also been vegan for the past 10 months.

Despite making choices to be healthy, Karlson reveals how she's continuously judged by her size because she feels that in today's society no one can be considered fit and healthy if they look like her.

"Here's to the big girls who work out," she captions her post. "I'll be honest - it still makes me cringe to refer to myself as big, but at 5'9 and 200+ lbs. it's an accurate descriptor."

"I've worked out four to six days a week every week since February of 2010. That's almost seven years," she continues. "I've been vegetarian since August 2015 and vegan since March 2016. I have practiced Transcendental Meditation for two years. I eat so many vegetables. I'm healthy AF. And yet my BMI places me squarely in the "obese" category."

Unfortunately, constantly being categorized and labeled is something Karlson is all-too-familiar with. "When I was young, a kid and a teen and even into my 20s, I believed the people who told me I was out of shape, unathletic," she said. "I love my dad dearly, but he was one of them."

Despite being body shamed by those near and dear to her, Karlson still exercised and tried to be active, no matter the consequence.

"I felt humiliated to huff and puff and turn red and drip sweat when I exercised," she says. "I hated to be worse at *anything* than anyone. I saw exercise as punishment. I believed Jillian Michaels when she said I should want to die in the midst of a workout. But I overcame it."

Even though it's taken a while, Karlson is now at a place where she's grown to love and appreciate her body just the way it is.

"I still struggle with my body. But I don't struggle with how I feel in it. I feel fantastic in it," she says. "Here's to the big girls. We are amazing. And if you're a big girl who doesn't work out, you're amazing too. You have nothing to prove." We couldn't agree more.
