Body mass index
Body mass index (BMI) is the most commonly used tool to measure the ratio of weight to height in the world. It uses the ratio of height to weight to measure whether a person is too thin or too fat.
The body mass index is suitable for all people aged 18 ~ 65, except children, developing teenagers, pregnant women, wet nurses, the elderly and muscular people.
Body mass index (BMI) is a tool to evaluate the ratio of weight to height, but it can't reflect the body fat content. Too high fat content is a health risk factor.
