BMI (body mass index) is calculated from height and weight and used as a general screening tool for weight categories such as overweight and obesity. Insurers and clinical guidelines often use BMI thresholds (commonly 27+ with a related condition, or 30+ on its own) as part of eligibility criteria for GLP-1 weight-management prescriptions, though BMI alone doesn't capture body composition or individual health context.
