Body Mass Index or simply the BMI is a measurement of body fat or one’s thinness based on one’s height and weight. In simple language, BMI calculates the height to weight ratio determining the risks of weight-related issues.
Though it doesn’t measure body fat, it gives a somewhat ideal estimation based on an equation. The equation delivers its evaluation after dividing a person’s weight by the double (square) of their height.
For adults, a body mass index of around 18.5 to 24.9 is the healthy amount. Something below it is considered underweight while above it is considered either overweight or obese. A BMI score of 30 or higher indicates obesity and morbid obesity.
|Normal Weight||18.5 – 24.9|
|Overweight||25 – 29.9|
|Obese||30 – 39.9|
Please note that the BMI calculator is perceived differently for adults and children though they are calculated the same way. The index is age-specific, and not to mention, sex-specific as well. It’s different because of the difference in growth and development in males and females.
The index will be of better use if you’re not pregnant and above 20 years of age.

4. Is BMI reliable?
It’s criticizable. Since BMI doesn’t differentiate between fat and muscle, it’s controversial. It also doesn’t process where the body fat is stored, but it offers a good estimation.
For basic checks, it’s reliable but for more detailed study, it’s not quite so. Here’s a more detailed study.
