Queensland scores a B+ when it comes to quitting smoking but more than one in eight Queenslanders are overindulging in alcohol.
Anxiety, depression, cardiovascular disease, cancer and diabetes are also common chronic diseases causing premature deaths and costing Queensland billions of dollars, chief health officer Dr Jeannette Young says.
"Obesity - that's the really big one in more ways than one," Dr Young told reporters at the launch of the Health of Queenslanders report in Brisbane on Friday.
"This year in Queensland alone $11.6 billion is spent because we've got overweight and obese Queenslanders.
"What you eat is probably the most important outcome for your health."
Every week, the deaths of more than 100 Queenslanders could be prevented, according to the report.
The spotlight also is on the growing epidemic of childhood obesity and the poor state of indigenous health.
Indigenous health is a long-standing issue, affected by a number of external factors including housing and education.
Obesity in children is largely caused by the proliferation of junk food marketing and lack of exercise, the report said.
"If we don't do something our kids are going to be the first kids ever that will live a shorter life span than their parents, and that's a really scary thing," Dr Young said.
According to the report, Queenslanders have one of the longest life expectancies in the world, scoring eight out of 10.
"While we enjoy good health by measures such as length of life or quality of life, we cannot afford to ignore the challenge present by the prevalence of chronic disease," Dr Young said.
