BMI (Body Mass Index) is a simple measurement used to assess whether a person has a healthy body weight for a given height. It is calculated by dividing a person’s weight in kilograms by the square of their height in meters (kg/m²).

BMI is commonly used to categorize individuals into weight categories, such as underweight, normal weight, overweight, or obese, which can help assess the risk of health problems related to weight. However, BMI doesn’t consider factors like muscle mass, bone density, or fat distribution, so it’s not a perfect indicator of overall health.
