BMI (body Mass Index) Is Unrealistic.
I am 6'0 and weigh 190. I go to the gym regularly and am pretty healthy. However, by the BMI i am over-weight. It doesn't take into consideration muscle mass and is in general unrealistic. Weight norms are based on BMI and it does not speak to overall health of the individual.

I have always said this. It is simplistic and riddled with flaws. I am built solidly, I have always been, even when I was really fit. Yet I am an inch shorter than my friend Carl who has always naturally been a beanpole. To compare how overweight we are based on our height is just ridiculous.

I think it works if you live in parts of Asia or
Africa.

It's only really good if you want to gauge to what degree someone is overweight - say for example a 30 stone dude.
If however you are a body builder, you are unlikely to be overweight - as the scale suggests.
I've got a BMI of about 20 - this i trust because I don't really do much exercise and am slim. If I built up some muscle it is likely that I will have a higher bmi, but still have little fat.

Yes, I can agree, based on that. I myself am considered slightly overweight, but I am quite healthy.

BMI calculations are remarkably annoying and I all but gave up on them when it determined that at just shy of 5.9 feet and with a weight of 174 pounds my BMI was apparently 25.7 and hence, I can be considered overweight. Many of these online calculators do not even bother to ask you your age, gender, or questions about your lifestyle.

I am hardly a macho bodybuilder, but I do have a relatively muscular build, which automatically pushes you over the edge into the overweight category when you calculate your BMI. Additionally, the contemporary obsession in some circles with BMI calculations and weight loss in general means that people often fail to take into consideration scientific studies which suggest that being slightly "overweight" does not pose any health risks at all.

I am five foot two and weigh 110lbs, and my BMI says I am underweight, and I am certainly not.
I expect to have comments like I am obviously anorexic then and all that b*llsh*t.

Would any of it matter if this planet lack gravity? I mean would it still have an effect on our life span without the resistance?

I think its a pretty good general indicator. People who are too thin or too fat will be exposed. And it does take into consideration some factors such as race. For example there is an Asian BMI index which is adjusted as Asians are slimmer.

Those who go to the gym who have enormous amount of muscle mass are unnatural anyway, in the same way that those who over-diet and are too skinny are unnatural. Having enormous muscle mass will only put you marginally within the overweight section. Rugby players tend to fall into that category, their physique is totally unnatural anyway. I think BMI is a good indicator.

Its a great gauge because generally most people don't exercise regularly. But the body does consistently burn a certain amount of energy and calories just for being awake and asleep and that is where the basis of that data comes from. And as you workout the BMI adjust. Its not a fixed number.

 I think you are wrong on this. "Body mass index (BMI) is a measure of body fat based on height and weight that applies to both adult men and women" It doesn't calculate in muscle at all. http://www.nhlbisupport.com/bmi/

If you know of an alternate calculation, i would be interested.
