Questions
What is a healthy BMI?
A BMI between 18.5 and 24.9 is generally considered healthy for adults. Below 18.5 is underweight; 25–29.9 is overweight; 30 or above is obese.
Is BMI accurate?
BMI is a quick screen, not a full picture. It doesn't distinguish muscle from fat, so very muscular people can read 'overweight'. Use it as a starting point, not a diagnosis.
