Understanding BMI
What is BMI?
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared.
BMI Categories
• Underweight: Below 18.5
• Normal weight: 18.5 - 24.9
• Overweight: 25 - 29.9
• Obesity: 30 and above
These ranges may vary based on factors like muscle mass and ethnicity.
Limitations
BMI doesn't account for muscle mass, bone density, overall body composition, and racial/sex differences. Athletes with high muscle mass may have a high BMI but low body fat.
