As health consciousness continues to rise across Australia, so too do the variety and influence of dietary trends shaping the way Australians eat. In 2025, the nation is witnessing a dynamic shift toward more personalized, sustainable, and science-backed eating habits — from high-fat, low-carb keto diets to eco-friendly plant-based lifestyles.

One of the most enduring trends remains the ketogenic (keto) diet , which focuses on high-fat, moderate-protein, and very-low-carbohydrate intake to promote fat burning and improved energy levels. Though initially popular among fitness enthusiasts, keto has now entered mainstream Australian culture, with many supermarkets offering dedicated keto product lines including low-carb bread, snacks, and ready-to-eat meals. Health professionals note that while some individuals report increased focus and weight loss, long-term sustainability remains a concern for many.
At the opposite end of the spectrum, plant-based diets are gaining momentum at an unprecedented pace. According to a 2025 report by Roy Morgan Research, over 2.6 million Australians now identify as either vegetarian or vegan — a number that has doubled since 2020. This shift is driven by growing concerns about climate change, animal welfare, and personal health. Major food retailers like Woolworths and Coles have responded by expanding their plant-based ranges, while fast-food chains such as Grill’d and KFC Australia continue to introduce innovative meat-free options.
The popularity of flexitarianism — a primarily plant-based diet that occasionally includes meat — is also rising. Many Australians are adopting this approach as a more flexible alternative to strict veganism, allowing them to reduce their meat consumption without completely eliminating it. This trend is particularly strong among younger generations, who prioritize ethical sourcing and environmental impact when making food choices.
Meanwhile, Mediterranean-style eating patterns are being increasingly promoted by nutritionists and public health organizations. Emphasizing whole grains, legumes, olive oil, fresh vegetables, lean proteins, and moderate red wine consumption, this diet aligns with the Australian Dietary Guidelines and is associated with lower rates of heart disease and improved longevity. In 2025, government health campaigns have begun highlighting the benefits of Mediterranean eating as part of broader efforts to combat obesity and diabetes.
Another emerging movement is regenerative and local eating , where consumers prioritize foods grown using environmentally sustainable practices and sourced within their own region. Farmers’ markets, community-supported agriculture (CSA), and farm-to-table restaurants are flourishing in cities like Melbourne, Sydney, and Adelaide, reflecting a growing desire to reconnect with food sources and support local producers.
In the world of beverages, functional drinks are becoming a staple in Australian households. These include kombucha, matcha lattes, adaptogen-infused waters, and probiotic-rich smoothies that promise not only hydration but also cognitive and immune benefits. Supermarkets now dedicate entire aisles to these wellness-focused drinks, catering to a population increasingly interested in holistic well-being.
