What does a BMI of 30.9 mean?

Your BMI of 30.9 kg/m² indicates obesity.

At 1.80 m (180 cm) and 100 kg, your BMI is 30 or above. Obesity significantly increases health risks including heart disease, type 2 diabetes, certain cancers, and joint problems.

Recommended actions:
  • Consult your healthcare provider for a comprehensive health assessment
  • Target weight: 59.9-80.7 kg (you need to lose 19.3 kg)
  • Start with small, sustainable changes—even 5-10% weight loss improves health
  • Work with healthcare professionals on diet, exercise, and possibly medical treatment

Remember: BMI is a screening tool, not a diagnostic measure. It doesn't account for muscle mass, bone density, or where fat is distributed. Always consult healthcare professionals for personalized health advice.
