Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women.
BMI Categories:
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5-24.9
- Overweight: BMI 25-29.9
- Obesity: BMI 30 or greater
Limitations of BMI:
- Doesn't distinguish between muscle and fat mass
- May not be accurate for athletes or muscular individuals
- Doesn't account for age, sex, or ethnicity
- May not be suitable for elderly or children
BMI is a screening tool, not a diagnostic tool. Consult with healthcare professionals for comprehensive health assessments.
