To help your doctor better assess your overall health, measure your waist size too.

A big waist size matters because, even if you re not overweight or have a low BMI, it could indicate you have more fat stored around your abdominals, so-called abdominal obesity .

According to the Centers for Disease Control and Prevention, here are the guidelines that put you at higher risk of obesity-related conditions:

A man whose waist circumference is more than 40 inches

A non-pregnant woman whose waist circumference is more than 35 inches

To find out your waist circumference, use a measuring tape get it from a drug or fabric store and wrap it around your belly button.

Consider taking these measurements first thing in the morning, after using the bathroom, and without a shirt on to keep measurements as accurate as possible.

Make sure that the tape is horizontal across your waist and that it s not pulling tightly on your skin.

Some say measuring waist-to-hip ratio is better, but Harvard School of Public Health Obesity Prevention Source noted their research showed that waist size alone and waist-to-hip ratio measurements were both equally effective.
