With half a million Australians now using or trying popular GLP-1 weight-loss and diabetes medications, the way we think about appetite and health is undergoing a massive shift. 

Private prescriptions are soaring, out-of-pocket costs are hitting hundreds of dollars a month, and this revolution is doing more than changing waistlines—it’s completely reshaping the food industry. Dave is joined by Registered Nutritionist Dr Emma Beckett for our weekly segment Nutrition Decoded to break down the GLP-1 boom and explore whether everyday food really can act as your medicine.

• The Massive GLP-1 Surge: How monthly usage skyrocketed to 500,000 Australians, with private prescriptions driving nearly 44% of total use.

• The Cost Barrier: Examining the equity challenges as private users pay between $200 and $700 out of pocket each month.

• Reshaping the Supermarket: Why food manufacturers are racing to design high-protein, nutrient-dense, portion-controlled products to match changing consumer appetites.

• Can Food Be Your Medicine?: How proteins, healthy fats, and fermentable fibres naturally trigger your body to release its own GLP-1 hormones.

• Biology vs. Behaviour: Why lifestyle and genetics mean changing your diet isn't always as simple as "eating less."

If you want to understand the science behind the headlines and how food science is evolving, this is the deep dive you need.
