What is BMI?

Body Mass Index (BMI) is a simple calculation used to assess whether a person has a healthy body weight for their height. It is calculated using the formula:

BMI = weight (kg) / height² (m²)

Alternatively, for pounds and inches:

BMI = (weight (lbs) / height² (in²)) × 703

Limitations of BMI

While BMI is a useful screening tool, it does not measure body fat percentage or distribution. Factors like muscle mass, age, gender, and body composition should also be considered for a complete health assessment.
