Calculate your Body Mass Index and assess anorexia risk
—
| BMI | Category | Risk |
|---|---|---|
| Below 15.0 | Severe Anorexia | Critical Risk |
| 15.0 – 15.9 | Moderate Anorexia | Very High Risk |
| 16.0 – 16.9 | Mild Anorexia | High Risk |
| 17.0 – 18.4 | Underweight | Medium Risk |
| 18.5 – 24.9 | Normal weight | Low Risk |
| 25.0 – 29.9 | Overweight | Enhanced Risk |
| Above 30.0 | Obese | High Risk |
Body Mass Index (BMI) is a widely used measure to assess body weight relative to height. For individuals with extreme low body weight, such as those suffering from anorexia, BMI can help evaluate health risks and monitor progress. The Anorexic BMI Calculator provides a quick and accurate way to calculate BMI and determine whether the weight falls within the anorexic range.
BMI is calculated using the following formula:
BMI = Weight (kg) / (Height (m))²
Or in pounds and inches:
BMI = (Weight (lb) × 703) / (Height (in))²
| BMI Range | Category |
|---|---|
| < 16.0 | Severely underweight (Anorexic) |
| 16.0 – 18.4 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |
| ≥ 30 | Obese |
Problem: A person weighs 38 kg and is 1.65 meters tall. Determine their BMI.
Formula: BMI = Weight / (Height)²
Solution: BMI = 38 / (1.65 × 1.65) = 38 / 2.7225 ≈ 13.95
Interpretation: BMI < 16 → Severely underweight (Anorexic)
Problem: A person weighs 80 lb and is 65 inches tall. Determine their BMI.
Formula: BMI = (Weight × 703) / (Height)²
Solution: BMI = (80 × 703) / (65 × 65) = 56240 / 4225 ≈ 13.31
Interpretation: BMI < 16 → Severely underweight (Anorexic)
1. What is BMI?
Body Mass Index (BMI) is a number calculated from weight and height to categorize weight status.
2. What BMI range indicates anorexia?
BMI less than 16 is considered severely underweight and may indicate anorexia.
3. Is BMI the only measure for anorexia?
No, BMI is one indicator. Diagnosis also considers medical evaluation, eating habits, and mental health.
4. Can I use this calculator at home?
Yes, it is a simple tool for awareness and tracking, but always consult a medical professional for health decisions.
5. Does age affect BMI interpretation?
BMI ranges may differ for children, adolescents, and elderly. This calculator is primarily for adults.
6. Can I use pounds and inches?
Yes, the formula BMI = (Weight × 703) / (Height)² works with pounds and inches.
7. Can BMI alone diagnose anorexia?
No, it is an indicator. Clinical evaluation is required for proper diagnosis.
8. How often should I check BMI?
For monitoring, weekly or monthly tracking is sufficient, depending on medical guidance.
9. Can extremely low BMI be dangerous?
Yes, a BMI below 16 increases risk of organ failure, malnutrition, and other health complications.
10. Is this calculator free and easy to use?
Yes, it is completely free and designed for quick, accurate assessments.
