Bmi (body Mass Index Calculator)

[mabhishekjhawar 0]

Body mass index (BMI) or Quetelet Index is a statistical measure of the weight of a person scaled according to height. It was invented between 1830 and 1850 by the Belgian polymath Adolphe Quetelet during the course of developing "social physics".

As a measure, BMI became popular during the early 1980s as obesity started to become a discernible issue in prosperous Western society. BMI provided a simple numeric measure of a person's "fatness" or "thinness", allowing health professionals to discuss over- and under-weight problems more objectively with their patients. However, BMI has become controversial because many people, including physicians, have come to rely on its apparent numerical "authority" for medical diagnosis – but that has never been the BMI's purpose. It is meant to be used as a simple means of classifying sedentary (physically inactive) individuals with an average body composition. For these individuals, the current value settings are as follows: a BMI of 18.5 to 25 may indicate optimal weight; a BMI lower than 18.5 suggests the person is underweight while a number above 25 may indicate the person is overweight; a BMI below 17.5 may indicate the person has anorexia or a related disorder; a number above 30 suggests the person is obese (over 40, morbidly obese).

 

For a given height the BMI is proportional to weight; for example, if body weight increases by 50%, BMI increases by 50%. For a given body shape and given density, the BMI is proportional to height--if all body dimensions increase by 50%, the BMI increases by 50%. This tendency for taller people to have higher BMIs is partially offset by the fact that many taller people are not just "scaled up" short people, but rather tend to have narrower frames in proportion to their height.

The problem with BMI is that it doesn't take into accuont your body's fat/muscle composition. you could weigh a lot because you're mostly muscle, which is perfectly healthy, but this high weight will give you a high BMI which might say you're obese, even though you're not. As with all things, it's important to keep common sense in mind.

Yes that system does have its flaws but it does have a few uses. It could be a good wake up call for a lazy person who doesnt really care... they go to a doctor and have this done and BAM. they care.... okay maybe not. XD But a lot of times doctors not only take into account your height and weight, but also your weight size and more modern tests include muscle mass testings... Better meathods come out every day. But besides all that, I dont really beieve in the whole number thing. It is just kinda asking for people to feel bad about themselves when they get stuck into some retarded weight category and people tell them to lose weight because of what some stupid calculator says. I mean honestly...

Agree that the system is indeed flawed. Not only this, I realise some medical tests is flawed as well. For example, I know of someone is an exercise freak. He does cardio and resistance training on a routine daily basis. He goes for a 10km run once a week. And when he went for his medical test, it shows that he has high chloestrol and the advice given, exercise more.
