B.M.I. Calculator

The Body Mass Index (BMI) is a measure of body fat in an individual based on height and weight. It classifies individuals as underweight, normal, overweight, or obese. The formula for calculating BMI is: weight (in kilograms) divided by height (in meters) squared. As an example, a person weighing 70 kilograms and being 1.75 meters tall has a BMI of 22.9 (70 / (1.75 x 1.75) = 22.9).

A BMI of 18.5 or less is classified as underweight, a BMI of 18.5 to 24.9 is considered normal weight, 25 to 29.9 is classified as overweight, and 30 or greater is obese. the BMI is not always an accurate indicator of the amount of body fat, as it does not take into account factors such as muscle mass, truncal obesity and overall body composition.

The BMI has been widely used as a measure of body fatness for over a hundred years , and is used by health care  professionals, scientists and researchers across the world. It is also used by insurance companies, employers, and other organizations to quantify health risks and make decisions about insurance coverage and other benefits.

The BMI has limitations. It may not accurately reflect body fat levels in athletes or older adults, and it does not take into account the distribution of body fat (eg. truncal obesity).

In recent years, other more precise measures of body fatness have been developed, such as the Body Adiposity Index (BAI) and the Body Shape Index (ABSI). These new measures take into account factors such as hip circumference and waist-to-height ratio, which are more closely related to health risks than the BMI.

In conclusion, BMI is a popular measure of body fat, but it has its limitations. It is important to consider other factors when assessing body fat levels and the consequent overall health risks. It is important to consult a medical professional to get a proper assessment of health rather than rely solely on this one single measure.
