About Body Mass Index (BMI)

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It's calculated by dividing your weight in kilograms by your height in meters squared.

BMI Formula

• Metric: BMI = weight (kg) / [height (m)]²
• Imperial: BMI = [weight (lbs) / [height (in)]²] × 703

Important Notes

• BMI is a screening tool and not a diagnostic of body fatness or health
• It doesn't distinguish between muscle and fat mass
• Athletes with high muscle mass may have a high BMI but low body fat
• BMI may not be accurate for children, pregnant women, or elderly adults
• Always consult with a healthcare provider for personalized health advice

Limitations of BMI

While BMI is a useful screening tool, it has limitations:

• Doesn't account for muscle mass, bone density, or body composition
• May overestimate body fat in athletes and muscular individuals
• May underestimate body fat in older adults who have lost muscle mass
• Doesn't consider distribution of fat (which affects health risks)
