BMI is one of the most widely used health screening tools but is frequently misunderstood. Here is what the numbers mean for women and where the measure falls short.
BMI Categories for Women
| BMI Range | Category | Health Implication |
|---|
| Below 18.5 | Underweight | May indicate nutritional deficiency |
| 18.5 to 24.9 | Normal weight | Associated with lowest health risk |
| 25.0 to 29.9 | Overweight | Slightly elevated risk |
| 30.0 plus | Obese | Increased health risk |
Average BMI for Women
- UK women: Average BMI of 27.2 (overweight range)
- US women: Average BMI of 29.6 (borderline overweight/obese)
- Healthy target: BMI 21 to 23 is often cited as ideal for minimising long-term health risks
Where BMI Falls Short
- Muscle mass: Athletic women may have an overweight BMI while being extremely healthy
- Body fat distribution: BMI does not distinguish visceral fat from subcutaneous fat
- Ethnicity: Asian women tend to carry health risks at lower BMI values than standard thresholds suggest
