Essentially "Body Mass Index" isn't the right obesity measurement to use going forward in this day and age, it simply doesn't work. Where as "Body Volume Index" does. BVI offers a brand new way of measuring the abdominal area, which BMI simply cannot do.
BVI is specifically designed to calculate risk factors associated with a person's body shape and type, through analysis of weight and body fat distribution.
