What is "BMI"?

BMI (Body Mass Index) is calculated by dividing weight (kg) by height (m) squared. It's an international standard for measuring obesity. For Asians, normal BMI is 18.5-22.9, overweight is 23+, and obese is 25+.

Example: Height 170cm, Weight 65kg → BMI = 65 ÷ (1.7)² = 22.5 (Normal)

¿Qué es el IMC?

El IMC (Índice de Masa Corporal) es una medida que usa tu altura y peso para evaluar tu estado de salud. Se calcula dividiendo tu peso en kilogramos por tu altura en metros al cuadrado.

Fórmula del IMC

BMI = weight(kg) ÷ height(m)²

IMC = peso(kg) ÷ altura(m)². Por ejemplo, una persona que pesa 70kg y mide 175cm de altura tiene un IMC de 70 ÷ 1.75² = 22.9.

Consejos para el Manejo Saludable del Peso

  • ✓El IMC es solo un indicador de referencia; no tiene en cuenta la masa muscular ni el porcentaje de grasa corporal
  • ✓El ejercicio regular y una dieta equilibrada son importantes
  • ✓Los cambios rápidos de peso pueden ser perjudiciales para tu salud
  • ✓Consulta a un profesional de la salud para una evaluación precisa de la salud

Expert Tip

Don't judge health by BMI alone. Athletes with high muscle mass can be healthy despite high BMI. Normal BMI with high visceral fat means 'skinny fat'. Measure waist circumference and body fat percentage together for accurate health assessment. Waist over 90cm (men) or 85cm (women) indicates abdominal obesity.

❓ Frequently Asked Questions

What is the ideal weight for my height?

Use BMI 22 as a reference. For example, at 170cm height, ideal weight is about 63.6kg (1.7 × 1.7 × 22). Normal range (BMI 18.5-22.9) is 53.5-66.2kg.

💡 Our calculator automatically shows your ideal weight range!

Is BMI 23 overweight?

For Asians, BMI 23+ is classified as overweight. This differs from Western standards (25+). Asians tend to have more visceral fat at the same BMI, so stricter criteria apply.

💡 Asian standards are more accurate for Korean users!

Does muscle mass affect BMI?

Yes! BMI only considers weight, so high muscle mass can show high BMI even without obesity. Body fat percentage measurement (InBody) is more accurate. Standard is 15-20% for men, 20-25% for women.

💡 If you exercise regularly, we recommend body fat measurement!

Is BMI calculation different for children/teens?

Ages 2-20 use the same formula but different interpretation. Results are evaluated by percentile among same age/gender. 85-94th percentile is overweight, 95th+ is obese.

At what BMI is health at risk?

Health risks (diabetes, hypertension, cardiovascular disease) increase sharply at BMI 25+ (Obese Class I). BMI 30+ is severe obesity requiring active management. BMI below 18.5 also risks malnutrition and weakened immunity.

📌 Key Takeaways

  • 📐BMI = Weight(kg) ÷ Height(m)² - simple calculation
  • 📊Asian normal BMI is 18.5-22.9, 23+ is overweight
  • ⚠️Don't judge health by BMI alone - check body fat too
  • 📏Measure waist circumference for more accurate obesity assessment

📊 Complete BMI Guide

What is BMI?

BMI (Body Mass Index) is calculated by dividing weight (kg) by height (m) squared. It's a simple measure of obesity developed by Belgian statistician Adolphe Quetelet in the 1830s. It's widely used worldwide as a quick indicator of overall health status.

⚠️ Limitations of BMI

BMI doesn't account for muscle mass, body fat distribution, or bone density. Athletes may have high BMI despite being healthy. Elderly people may have normal BMI but high body fat due to muscle loss. Use BMI as a reference only and consult a healthcare professional for accurate health assessment.
