The BMI calculator is a valuable tool that helps assess body composition by evaluating the relationship between a person’s height and weight. This evaluation helps determine if an individual is underweight, of normal weight, overweight, or obese. It widely describes whether you are in a healthy zone or need to lose or gain weight. BMI ranges may vary based on your exercise regime. The more you gain weight the more your BMI increases but this does not mean that you are obese. An increase in BMI can also be because of high muscle mass.
