Please read before interpreting your result
- BMI is a statistical indicator for populations, not a medical diagnosis.
- It does not distinguish muscle mass from fat mass: a muscular person can be classed as “overweight” without excess fat.
- The tool does not apply to people under 18, pregnant women or older adults.
- For any question about your health, consult a healthcare professional.
