Frequently asked questions
A BMI between 18.5 and 24.9 is considered normal weight. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is obese.
BMI is a general guide and doesn't distinguish muscle from fat, so it can be misleading for athletes or the elderly. Treat it as one indicator, not a diagnosis.
