One in three Australians are snacking less, and GLP-1s are accelerating the shift

Australia’s snack category has spent decades competing for one more bite. New research from Ideally suggests that opportunity is getting smaller.

One in three Australians (33%) say they’re snacking less often than they were a year ago, compared with 17% who are snacking more.Among Australians currently taking a GLP-1, the shift is far more pronounced.

Almost three quarters (73%) snack less often than before, while 58% are buying fewer sweet snacks, making them the most-cut category in the GLP-1 grocery basket.
Protein is taking a bigger share of a smaller appetite

As snacking declines, spending is shifting towards foods that deliver more nutrition and satiety.

Almost half of GLP-1 users (48%) are buying more high-protein foods, while 40% are buying more fresh fruit and vegetables, protein bars and shakes, and yoghurt.

“Grocery baskets were already shifting towards protein and lower sugar before GLP-1s arrived. What we’re seeing now is that trend accelerating. This is an existing shift gathering pace.”

The implications extend beyond today’s users. While 7% of Australians currently take a GLP-1, another 14% would consider taking one and 6% of former users would consider returning. Together, that puts 27% of Australian adults within the current or potential GLP-1 audience.

Smaller appetites are changing the value equation

The shift also reaches beyond what consumers buy.

Six in ten GLP-1 users (61%) say their total food and drink spend has decreased, while 31% now place greater importance on portion-controlled packs.

For snack brands, the challenge is increasingly about earning a place within fewer eating occasions. Protein, nutrition, portion size and satiety are becoming stronger signals of value as consumers become more selective about what they eat.

Inside the report
  • The appetite fingerprint: why one in three Australians have eaten less sugar in the past year
  • What GLP-1 users are buying more of, from protein and fresh produce to smaller portions
  • Why 61% of users say their food and drink spend has fallen, and what that means for value
  • How portion control is becoming more important to GLP-1 consumers
  • Where snack brands can respond and how to test emerging opportunities
