BMI-2: A Proposal for Modified Notion of BMI

Objectives: In this paper, we have justified that existing notion of Body Mass Index (BMI) does not signify the body fat mass with a good precision. So a new version of BMI called BMI-2 is proposed. Method: The body has some parts where chance of depositing the body fat is high i.e., waist, hip, thigh and neck etc. Here, in this paper, we have multiplied the circumferences of waist, hip, thigh and neck with the existing formula of BMI. Findings: A person with high circumferences of waist, hip, thigh and neck would be having comparatively higher value of new BMI-2 than that of others; even their old (existing) BMI values are same. Improvement: The new BMI-2 gives a comparatively better picture of health status by including the circumferences of some fat prone parts of the body. But if we had taken the weighted circumferences, the result would have been more accurate.
