Frequently asked questions
Is BMI an accurate health measure?+
BMI is a screening tool, not a diagnosis. It doesn’t account for muscle mass, bone density, or body composition, so it’s best used alongside other measures and a conversation with a healthcare provider.
What BMI ranges are considered "normal"?+
The standard adult ranges are: below 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, and 30+ obese. These categories don’t apply the same way to children, athletes, or older adults.
