Frequently asked questions
Is BMI accurate for everyone?
No - BMI doesn't distinguish muscle from fat and can be misleading for athletes, older adults, and some body types. It's a screening tool, not a diagnosis.
What counts as a healthy BMI range?
18.5–24.9 is generally classified as the healthy range, under 18.5 as underweight, 25–29.9 as overweight, and 30+ as the obesity range - but these cutoffs are population averages, not individual health verdicts.
