Yeah it's weird, I was just being lazy with wording, but now I want to defend BMI a little since it's not that stupid. (I meant to say he didn't look like the stereotypical image of a morbidly obese person, which in hindsight isn't very productive)

It's true that BMI is only useful for "normal" people, which excludes pro-athletes/body builders with a lot more muscle than the average person, and people with conditions that affect their weight. For the vast majority of people, it's a useful metric for overall health. Anyone who cares about longevity and quality of life shouldn't ignore it just because it's uncomfortable to think about or "seems wrong" based on some self assessments. Obviously, there's a lot of stigma around being labelled as obese, but people are judgy assholes about everything. What's basically guaranteed, though, is that if you do lose weight to reach a "healthy" BMI, you will feel a lot better physically (and probably also mentally). Pains you didn't even realize you had will go away, you'll have more energy, etc.

I'm not saying you should lose weight, idgaf. Your life isn't mine, and I'm not here to give unsolicited advice. I just feel compelled to add some extra context so people don't draw hasty conclusions.

Not necessarily. If he's 7'4" or taller he'd have a healthy BMI!
