The SIGMA BMI (Body Mass Index) calculator is a useful tool that can assist you in determining your optimal weight range based on your height and weight. Based on your BMI score you can determine if you are at a healthy weight or if you need to make changes to your lifestyle and diet. It is worth noting that BMI calculators are not always accurate indicators of health, and other factors such as muscle mass, body shape, and body composition should also be considered in determining an individual’s overall health status.
