BMI Calculator
Body Mass Index (BMI) is a simple calculation using a person's height and weight. While it doesn't directly measure body fat, it correlates with more direct measures of body fat.
Key Terms
- BMI (Body Mass Index) — A measure of body fat based on weight relative to height.
- BMR (Basal Metabolic Rate) — The number of calories your body burns at rest to maintain basic life functions.
- TDEE (Total Daily Energy Expenditure) — Total calories burned per day including BMR and physical activity.
- Weight Categories — Underweight, Normal, Overweight, and Obese ranges.
BMI Categories (Adults)
- Under 18.5 — Underweight
- 18.5 – 24.9 — Normal weight
- 25.0 – 29.9 — Overweight
- 30.0 and above — Obese
BMI Formula
BMI = weight(kg) / height(m)²
Limitations
- BMI doesn't distinguish between muscle mass and fat mass
- Athletes may have high BMI due to muscle, not fat
- May not be accurate for elderly people who have lost muscle
- Ethnicity and body composition can affect accuracy
