What is BMI and Why is it Important?
BMI (Body Mass Index) is a widely used measurement that compares your weight with your height to estimate body fat. While it does not measure body fat directly, it is a reliable indicator of whether a person is within a healthy weight range.
BMI Categories (WHO Standard):
Underweight: BMI below 18.5
Normal weight: BMI between 18.5 and 24.9
Overweight: BMI between 25 and 29.9
Obesity: BMI above 30
Knowing your BMI is important because it helps identify potential health risks such as:
Heart disease
High blood pressure
Type 2 diabetes
Joint problems
