Frequently asked questions
Is BMI accurate?
BMI is a useful screening tool but has limitations. It doesn't account for muscle mass, bone density, body composition, or fat distribution. Athletes with high muscle mass may have a high BMI but low body fat. Use it as a general guideline, not a diagnosis.
What is a healthy BMI?
A BMI between 18.5 and 24.9 is considered healthy for most adults. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese. These ranges are based on population studies and may not apply to all individuals.
Does BMI differ by age or gender?
The standard BMI categories are the same for all adults regardless of age or gender. However, women typically have higher body fat percentages than men at the same BMI. For older adults, a slightly higher BMI (up to 27) may be associated with better health outcomes.
What's a better measure than BMI?
Body fat percentage, waist-to-hip ratio, and waist circumference are often more accurate measures of health risk. DEXA scans, bioelectrical impedance, and skinfold calipers can measure body fat more precisely than BMI alone.
