You know there's a difference between her perception of herself and our perception of her, right? It's not about whether she's actually fat or not. She thinks she's at least getting fat, so she wants to do something about it.So, she's fat with a BMI of 21.5? What kind of bulshit is this?
BMI is a poor metric of whether you're at a healthy weight or not because even if you're at 21.5 you can still have an unhealthy body fat percentage, i. e., you're "skinny fat". Given that this girl has never exercised before and eaten a lot of unhealthy food for an extended period of time, this is quite likely the case. Starting to work out is a great way to fix this!So, she's fat with a BMI of 21.5? What kind of bulshit is this?
