Understanding BMI & Health Assessment

What is BMI?

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It doesn't directly measure body fat, but it's a useful screening tool for identifying potential weight problems.

BMI Formula:

BMI = weight (kg) ÷ (height (m))²

For imperial units, weight in pounds and height in inches

BMI Categories

BMI categories help assess weight status and potential health risks. However, BMI is not a diagnostic tool and should be used alongside other health assessments.

Underweight < 18.5
Normal 18.5 - 24.9
Overweight 25 - 29.9
Obese ≥ 30

BMI Limitations & Considerations

Muscle Mass

Athletes and muscular individuals may have high BMI without excess fat

Age & Gender

BMI interpretation may vary by age, gender, and ethnicity

Not Diagnostic

BMI is a screening tool, not a medical diagnosis
