1. What is BMI?

Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, normal weight, overweight and obesity in adults. It is calculated by dividing weight in kilograms by height in meters squared.

2. Asian BMI Standards

The calculator uses Asian-specific BMI categories:

Asian BMI Categories:

• < 18.5 — Underweight
• 18.5-22.9 — Normal range
• 23-24.9 — Overweight (At risk)
• 25-29.9 — Overweight (Moderately obese)
• ≥ 30 — Obese (Severely obese)

Note: Asian populations have different associations between BMI, percentage of body fat, and health risks compared to Caucasian populations.

3. Importance of BMI Calculation

Details: BMI is a quick screening tool for weight categories that may lead to health problems. For Asians, the risk of type 2 diabetes and cardiovascular disease begins at lower BMI levels than in Caucasians.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For height in centimeters, divide by 100 (e.g., 170 cm = 1.7 m).

5. Frequently Asked Questions (FAQ)

Q1: Why different BMI standards for Asians?
A: Asians generally have higher body fat percentage at lower BMI levels and higher risk of obesity-related diseases at lower BMI thresholds.

Q2: What's the ideal BMI for Asians?
A: The healthy range is 18.5-22.9 kg/m², with optimal around 21-22 kg/m².

Q3: Are there limitations to BMI?
A: BMI doesn't distinguish between muscle and fat mass, and may not accurately reflect body fat in athletes, elderly, or pregnant women.

Q4: Should children use this calculator?
A: No, children and teens need age- and sex-specific BMI percentiles.

Q5: What about waist circumference?
A: For Asians, waist circumference >90 cm (men) or >80 cm (women) indicates increased health risk regardless of BMI.
