Not at all.

I’m no medical expert either, I’ve just looked into this in my endeavour to take care of myself.

I’ve talked to both doctors and nutritionists about my body composition, and what to look out for if I want to alter it in some direction.

I really don’t like the way my face rounds out when my body fat gets to the 13-15% range, so most of my life I’ve maintained a mere 8-12% by altering my diet whenever things go in a direction I don’t want.

That’s easier as a man, but as a tall dude with disproportionately long limbs, who doesn’t get bulky even when I strength train, it does mean the rest of me ends up looking skinny to the point I start getting comments about “starving myself”, even though the numbers aren’t even close to unusual.

I do have muscle, I just have to flex them for it to really show, and because my limbs are long, and my fat genetically tends towards intravascular, people looking at me come to complete nonsense conclusions.

That I have personal experience with people trying to feed me more than I want to or actually need to eat, makes it especially irksome seeing it done to others.

Sure, if you have full overview of someone’s diet, exercise, and body composition, as well as a graph showing the changes in those things over time, then you could start making conclusions about what kind of changes may be warranted.

But someone’s weight and torso from a single point in time, tells you literally nothing unless they are visibly in the process of wasting, or morbidly obese.
