About BMI
Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight, and obesity in adults.
Underweight (BMI < 18.5)
This may indicate insufficient nutrition, potential health problems, or eating disorders. Consult with a healthcare professional.
Normal Weight (BMI 18.5 - 24.9)
This range is associated with the lowest risk of health problems. Maintain a balanced diet and regular exercise.
Overweight (BMI 25 - 29.9)
Increased risk of health problems. Consider lifestyle changes including diet and physical activity.
Obesity (BMI ≥ 30)
Higher risk of serious health conditions. Professional guidance is recommended for weight management.
Interpretation
While BMI is a useful screening tool, it has limitations:
- Doesn't directly measure body fat
- May overestimate body fat in muscular individuals
- May underestimate body fat in older persons
- Doesn't account for body composition differences
