FAQ
Is BMI accurate?
BMI is a useful population-level screening tool but doesn't account for muscle mass, bone density, or fat distribution. Athletes often have a high BMI despite being healthy.
What is a healthy BMI?
The World Health Organization defines 18.5–24.9 as 'normal' for adults. These ranges may differ for children, the elderly, and different ethnic groups.
