What Is BMI?
Body Mass Index (BMI) is a simple measurement that compares weight and height. It is widely used to estimate whether a person falls within a healthy weight range.
How BMI Is Calculated
BMI is calculated by dividing body weight in kilograms by height in meters squared. The resulting value is used to classify weight status.
BMI Categories Explained
Adults are generally classified as underweight, normal weight, overweight or obese based on their BMI value. These categories help assess potential health risks.
Why BMI Matters
BMI is commonly used by healthcare professionals as a quick screening tool to identify possible weight-related health concerns.
Practical BMI Example
A person weighing 70 kg with a height of 1.75 meters has a BMI of approximately 22.9, which falls within the normal weight category.
Limitations of BMI
BMI does not directly measure body fat. Athletes and individuals with high muscle mass may have elevated BMI values despite having healthy body composition.
BMI and Overall Health
BMI should be considered alongside other health indicators such as waist circumference, body fat percentage, physical activity and medical history.
