Obesity is one of the biggest health challenges in Saudi Arabia, with rates exceeding the global average. Body Mass Index (BMI) is an essential tool for assessing your weight and health. In this guide, we explain everything you need to know.
What is Body Mass Index (BMI)?
BMI is a measure that uses height and weight to determine whether a person is underweight or overweight. It is calculated using the formula:
BMI = Weight (kg) / Height (m)²

Limitations of BMI
Despite its usefulness, BMI has limitations:

Therefore, additional measurements like waist circumference and body fat percentage are recommended.
