Emma Gearon, lead researcher and research fellow in Deakin’s Global Obesity Centre, told Justin and Kate body mass calculators are not detecting the full scale of Australia’s obesity problem.

“We’ve always known that BMI has its limitations,” she said.

“It can’t differentiate as to whether you have a lot of muscle or whether you have a lot of fat mass.”
