Introduction to the Body Mass Index (BMI)
The Body Mass Index (BMI) is a simple and widely-used tool for estimating body fat based on your weight and height. It provides a quick snapshot of whether your weight falls within a healthy range for your height.
Merely checking your weight isn't always helpful—taller individuals naturally weigh more but may still be perfectly healthy. BMI helps adjust for height, offering a more accurate perspective on your overall health.
While BMI isn’t a perfect indicator of body fat or fitness, it's a helpful screening tool for identifying potential health risks associated with being underweight or overweight. Healthcare providers often use it to assess patients' health status and determine appropriate medication dosages.
Note: BMI is a general guide and may not apply equally to all body types, such as athletes or individuals with high muscle mass.
