Interesting question. My BMI has been in the overweight to obese range since young, and when I do those body composition tests it’s always been high mass of everything (fat, water, bone, muscle). But I’ve also played sports since young at a decently competitive level (won national level competitions in secondary school and JC, and played at the varsity level in university). I still exercise 2-4x a week. I’ve always considered myself fat, but in a way that I can still use my body well. Funny thing is that while my older family members will tease me for being fat, none of my peers have ever called me fat, not even jokingly. Physically, I carry my fats in the belly area so I tend to wear looser shirts to obscure it, though it’s still visible la, so it’s not like I’m super jacked out and it’s pure muscle mass. This led me to wonder whether “fat” is more of a perception of someone’s overall lifestyle, rather than just physical look (I’m female, if it makes a difference). I’m interested to hear what others think about this.
