Answer
For most people, BMI is a good tool because it’s easy to understand, and it can shed light on a problem that you are not aware of. Maybe you’re not sure where your weight should be. Or maybe your current weight is unhealthy, but it has come to seem normal to you over time.
But a true assessment of what’s right for you should include talking with your doctor. He or she may consider other measures, like waist circumference.
