The meanings of the four comprehensive metrics are as follows:
1. Weight: Body weight refers to the total sum of all components that make up the human body;
2. BMI (Body Mass Index): BMI (Body Mass Index) reflects the relationship between body weight (kg) and the square of height (m). It is closely related to body fat content and serves as an important indicator of physical fitness. Internationally, it is commonly used as a standard to measure the degree of leanness or obesity in individuals;
3. Weight control: Weight control amount = Standard weight reference value - Current weight (for reference only);
4. Standard weight: The standard weight reference value is calculated using the Standard Body Weight (SBW) formula. It represents the ideal weight for different heights and serves as a target for weight management goals.
