What does a BMI of 15.4 mean?

Your BMI of 15.4 kg/m² indicates you are severely underweight.

At 6'5" and 130 lbs, your body weight is significantly below the healthy range. A BMI below 16 may indicate malnutrition or an underlying health condition that requires medical attention.

Recommended actions:

  • Consult a healthcare provider to rule out underlying health issues
  • Work with a registered dietitian to develop a healthy weight gain plan
  • Focus on nutrient-dense foods and regular meals
  • Consider strength training to build muscle mass safely

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.
