@Damiola, this is unnecessarily argumentative. This is a strength and conditioning forum, and there can be healthy, strong athletes with a wide range of BMI numbers. For our purposes, it’s not useful. We aren’t giving advice about bariatric surgery. (And if someone’s doctor is using that as a metric, I’d recommended they get a second opinion.)The guy asked for advice on his appetite. My point was that for that some background information is required. Do you reckon it wouldn't make a difference if he said his BMI is 20 or 40?
As to BMI being clinical, it is used, for example, as the cutoff for bariatric surgery. Surgery is part of clinical medicine.
I’ve gotten slightly shorter as I’ve gotten older, a normal and common thing, and like most people, my weight fluctuates over a range of a few pounds. If I put in my current height and my worst-case weight, which is about 4 lbs more than I weighed this morning, an online BMI calculator tells me I’m obese, which is just ridiculous because, in our community here, I’m skinny. But 5’6” and 156 lbs is obese.
