🧠 How Is BMI Calculated?

BMI (Body Mass Index) is a simple metric used to estimate body fat based on height and weight. It’s used globally to screen for weight categories that may lead to health problems.

BMI = weight (kg) / height² (m²)

The app follows WHO standards for classification:

Underweight

Normal weight

Overweight

Obese (Class I, II, III)

While BMI doesn’t directly measure body fat, it’s a useful health screening tool and widely used by healthcare providers and fitness professionals.
