What is BMI
BMI (Body Mass Index) is an indicator used to measure the degree of obesity in the human body. It determines whether a person is within the healthy weight range by the ratio of weight to height.
BMI cannot accurately reflect the ratio of muscle mass to fat, so some fitness people may have a higher BMI, but it does not mean that they have too much body fat;
The role of BMI
- Assessing health risks: BMI can help estimate the health risks a person faces due to being underweight, overweight or obese, such as cardiovascular disease, diabetes, etc.
- Versatile: BMI is suitable for most adults, regardless of gender and age, and is widely used in health checks and weight management.

Where:
- H = Height(Meter)；
- W = Weight(Kilogram)
