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.
