Selfie app helps you watch your weight
The use of body mass index as a measure of obesity is about to change - with do-it-yourself 3D imaging.
Currently, BMI is calculated using a person's weight and height. However, that does not take into account muscle mass.
Body volume indicator (BVI) is a new tool to measure obesity that was developed by the UK company Select Research, in collaboration with the US Mayo Clinic and the UK Medical Research Council.
The software identifies body outlines in photos and compares the images to a database to calculate factors including body volume, abdomen volume, waist-to-hip ratio, visceral fat and BMI. It then generates a BVI number.
It's less complicated than it might sound. You download the BVI Pro app, enter your height and weight, then take two photos (one from the front and one from the side). The app will tell you what your BVI is, and if it is in good range.
