Lifestyle-related diabetes has become the fastest-growing disease in the country, with more than 275 Australians diagnosed with some form of diabetes each day.

And alarming projections show type 2 - or "lifestyle" - diabetes will overtake coronary heart disease, anxiety and depression as having the most severe impact on public health within just eight years.

Diabetes Australia Victoria chief Greg Johnson said with 243,000 Victorians now registered with some type of the disease, the highest growth had been among young adults.

There has been a 15 per cent rise in 21 to 29-year-olds diagnosed and an 11 per cent increase for those aged in their 30s over the past 24 years.

"It's a myth that diabetes only affects the older population, as we're now even seeing adolescents being diagnosed with type 2 diabetes," Prof Johnson said.

"It's the epidemic of the 21st century and the forecasts show it's only going to become a bigger burden of disease."

Type 2 diabetes is often triggered by a person gaining significant weight and not getting enough exercise.

Since the National Diabetes Services Scheme was set up in 1987, one million Australians with gestational, type 1 and type 2 diabetes have registered their condition.

The register provides support and subsided medical products.

Lifestyle-related diabetes accounts for about 85 per cent of these cases.

But Prof Johnson said about 60 per cent of type 2 diabetes cases could be prevented, or at least delayed, if people knew their risk factors and made lifestyle changes.

Broadmeadows mother Melita Blackney took charge of her health after a family history of type 2 diabetes put her in the high-risk category.

The 50-year-old lost 18kg after taking part in the Life! Taking Action on Diabetes program, learning how to incorporate more exercise and healthy eating into her daily routine.

Ms Blackney started by walking for 30 minutes a day and reducing portion sizes. She now does weights and has a personal trainer.

"I think we all know what to do - eat less and exercise more - but I lost the motivation after having the kids," she said.

"It's about changing your mindset, and now I feel better than I did when I was 30."
