Prime Minister John Howard will continue his visit to the marginal Federal seat of Bass by attending a Childhood Obesity forum in Launceston.
While holding back on details, Mr Howard indicated the Coalition will soon release a new anti-obesity policy to help prevent or overcome the health disorder.
"We need to get people exercising more, we need to get children playing more sport, we need to stop the drift away from less physical activity and less sport in schools," he said.
"We need to get people eating better and there are different ways in which the government can contribute."
Mr Howard says in the end it is a challenge for parents.
"It's parents who determine and set the eating habits of their children and we will encourage this in all that we do in this area and it will be quite a bit," he said.
