📈 BMI Chart (Asian standard, used in Korea)
| Category | BMI range | Health effects |
|---|---|---|
| 🔵 Underweight | Below 18.5 | Poor nutrition, risk of osteoporosis |
| 🟢 Normal | 18.5 to 22.9 | Healthy weight range |
| 🟡 Overweight | 23 to 24.9 | Risk of diabetes and high blood pressure starts to rise |
| 🔴 Obesity, stage 1 | 25 to 29.9 | Higher risk of heart and blood vessel disease |

💡 Note on BMI for older adults: Some studies have found that, for people aged 65 and over, death rates are lower in the BMI 23 to 27 range.
Because muscle shrinks with age (sarcopenia), your body fat can be high even when your BMI is low. Ask your doctor for an accurate assessment.
These cut-offs follow the Asian standard used in Korea. Other countries may use different cut-offs.
