I'm a size 12/14 and I'm clinically obese (BMI of exactly 30).
I am absolutely fat and I know I am.
My mother and aunt were size 14s too and they were fat. My best friend was fat when she was a size 14 too. Of course I'd never verbalise it, but it was true.
But we aren't allowed to be honest anymore, even to ourselves. "Fat" doesn't begin until size 20 these days, if at all. It's all about "body positivity" even if you're morbidly obese and your life is at risk.
Cue all of the "bmi is a blunt tool", "I am 8 stone, 6 foot and a size 14" posts.
Do I believe some people are "big boned" and "athletic" and can be a size 14 and not be fat? Yes, I genuinely do.
Do believe some people (like me) are genuinely quite fat at a size 14? Also yes. And it wouldn't help me if patronising people kept telling me I was just "curvy", "normal sized", "lovely and healthy looking" as I get told frequently. The current, unusual for my young age, state of my health tells me very differently.
So yes, I'm a fat 12/14 and I'm doing something about it. My heart, lungs and joints will thank me for it later, as will my kids.
