What is Body Mass Index (BMI)?
Body Mass Index (BMI) is an internationally recognized screening metric created to gauge whether an individual has a healthy body weight relative to their height. Health organizations such as the World Health Organization (WHO) and CDC use BMI to assess body fat categories and potential health risks.
BMI Formula
Metric: BMI = weight (kg) / [height (m)]²
Imperial: BMI = 703 × weight (lbs) / [height (in)]²
BMI Classifications (WHO Standards)
- Underweight: BMI less than 18.5
- Normal Weight: BMI between 18.5 and 24.9
- Overweight: BMI between 25.0 and 29.9
- Obese: BMI 30.0 or higher
Frequently Asked Questions
Is BMI accurate for athletes and bodybuilders?
BMI measures total body mass and does not distinguish between dense muscle mass and adipose fat tissue. Muscular athletes may register as overweight despite possessing low body fat percentages. For general adults, however, BMI provides a reliable baseline health indicator.
