The 2024 Australian Institute of Health and Welfare (AIHW) report paints a troubling picture of the nation’s health, revealing a worsening epidemic of obesity, type 2 diabetes, and chronic disease. Beneath the stark statistics lies a growing issue that has been decades in the making: the impact of dietary guidelines, ultra-processed food consumption, and systemic barriers to meaningful change.
Obesity: A national epidemic
Obesity rates in Australia remain alarmingly high. According to the AIHW report, three-quarters of Australian men are overweight or obese, and the proportion living with obesity has increased from 32% to 34% in just one year. For women, the statistics are no less concerning, with 61% overweight or obese and obesity itself rising from 29% to 30%.
Globally, Australia’s ranking remains dire. Among OECD nations, Australian men have the fourth-highest obesity rate, trailing only the United States, Hungary, and New Zealand. For women, Australia is ninth—a worrying indication that our policies are not making a meaningful impact.
A growing burden
The surge in obesity rates has brought an unsurprising but devastating consequence: type 2 diabetes.
The AIHW report notes that the number of Australians living with type 2 diabetes has nearly tripled in the past two decades, from around 400,000 in 2000 to almost 1.2 million in 2021.
Alarmingly, this trend shows no signs of slowing. In the past year alone, diabetes diagnoses among men rose from 705,400 to 715,000.
These figures highlight an undeniable truth: type 2 diabetes is no longer a condition affecting only older Australians. Increasingly, it’s striking younger age groups, exacerbating the nation’s already stretched healthcare resources.
Ultra-processed foods: A key culprit
Evidence increasingly links the rise in chronic disease with the explosion of ultra-processed food consumption. Products laden with refined carbohydrates, added sugars and unhealthy fats dominate Australian diets, contributing to excess calorie intake, insulin resistance, and chronic inflammation—hallmarks of type 2 diabetes and obesity.
This trend isn’t isolated to Australia. Globally, countries following similar dietary patterns have seen parallel rises in obesity and diabetes. Yet Australia’s persistence in adhering to outdated dietary guidelines—which emphasise carbohydrates and vilify fats—places it squarely on the wrong side of history.
Rethinking dietary guidelines
Australia’s dietary guidelines have long championed a high-carb, low-fat approach. While well-intentioned, this advice has backfired. Carbohydrate-rich foods, including bread, pasta, and cereals, are often ultra-processed and rapidly converted to glucose, driving insulin spikes and long-term metabolic issues.
The Defeat Diabetes movement and other advocates have demonstrated that low carb, whole-food diets can reverse type 2 diabetes and improve metabolic health. By prioritising natural fats, protein, and non-starchy vegetables over processed carbs, Australians can break free from the cycle of weight gain and disease.
Recommendations for change
If Australia is serious about tackling its obesity and chronic disease crises, bold steps are needed:
- Overhaul dietary guidelines: Shift the focus away from high-carb, low-fat recommendations to an evidence-based, low carb, whole-food approach.
- Regulate ultra-processed foods: Introduce policies to limit the marketing, availability, and affordability of ultra-processed foods, especially to children.
- Subsidise healthy options: Make whole foods like fresh vegetables, lean proteins, and healthy fats more accessible and affordable.
- Launch public health campaigns: Increase public awareness about the dangers of ultra-processed foods and the benefits of low carb eating.
- Tax sugar-sweetened beverages: Discourage consumption through targeted taxes, reinvesting funds into preventive health programs.
The road ahead
The AIHW’s 2024 report should serve as both a wake-up call and a catalyst for change. As the number of Australians facing obesity and chronic disease grows each year, the cost of inaction becomes untenable. It’s time for governments, health professionals and individuals to reject outdated advice and embrace strategies that work.
The rise of type 2 diabetes and obesity is not an inevitable by-product of modern life. It’s the result of choices—in our diets, policies, and priorities. With the right changes, Australia can turn the tide, improving health outcomes for generations to come. But the question remains: Will we act before it’s too late?
