Eat less, live longer.
Millions of overweight Australians could add 10 years to their lives by sharply reducing their calorie intake, according to Australian researcher Arthur Everitt.
Associate Professor Everitt, of the University of Sydney's Centre for Education and Research on Ageing, said studies in rats had found cutting their calories by 20 per cent significantly prolonged life.
"We don't have the same evidence in humans of actually prolonging life but we do know that people eating fewer calories have fewer risk factors for common diseases - things like high blood pressure, high blood fats and poor blood sugar control leading to diabetes," he said.
"It's absolutely essential not to become obese. About 10 years is lost by being obese."
Nevertheless, Australians were living an average 30 years longer than they were a century ago, Prof Everitt said.
The increase was largely due to a reduction in smoking and the development of medications to lower blood pressure and cholesterol.
He will address the International Conference on Healthy Ageing and Longevity in Brisbane next month.
Other speakers include American Thomas Perls, the director of the New England Centenarian Study who will talk about what it takes to reach 100.
