An overhaul of how obesity is diagnosed could be on the way

The Global Commission on Clinical Obesity has made recommendations that diagnosis is focused on measures of total body fat, not just BMI.

The paper says current practices rely too heavily on body-mass indexes.

Endocrinologist Rinki Murphy says it won't mean people can just diagnose obesity by standing in front of the mirror.

She says it becomes unhealthy when fat goes into organs - and it's not able to be seen by the bare eye.
