About BMI

BMI (Body Mass Index) is a screening tool, not a diagnosis. Muscular athletes, pregnant people, and the elderly often fall outside the typical ranges for reasons unrelated to health. Always consult a doctor for a proper health assessment.

Underweight: BMI < 18.5
Normal: 18.5 - 24.9
Overweight: 25 - 29.9
Obese: 30+
