For millions battling obesity worldwide, a new class of weight-loss medications is offering more than just health benefits—it's reshaping their shopping baskets and eating habits. A groundbreaking study has now quantified this shift, revealing a significant drop in food expenditure among users of these popular drugs.
Beyond Appetite Suppression: A Financial Impact
Research from Cornell University, published in the Journal of Marketing Research, provides concrete data on how GLP-1 receptor agonists like Ozempic and Wegovy influence real-world spending. Analysing purchase data from approximately 150,000 households tracked by market research firm Numerator, the study found a clear trend.
Within six months of starting a GLP-1 medication, average grocery spending fell by 5.3%. The reduction was even more pronounced in higher-income households, where spending plummeted by over 8%. The trend wasn't confined to supermarket aisles. Expenditure at fast-food outlets, coffee shops, and other limited-service restaurants also saw a sharp decline of around 8%.
"The data show clear changes in food spending following adoption," stated Sylvia Hristakeva, assistant professor of marketing at Cornell and a lead researcher. She noted that these lower spending patterns persisted for at least a year among medication users.
What's Leaving the Shopping Cart?
The study moved beyond self-reported habits to analyse actual transaction records, offering a robust picture of changing consumption. The most dramatic declines were seen in categories typically associated with cravings.
Purchases of ultra-processed and calorie-dense foods dropped sharply. There was a 10% decrease in savory snacks, with the largest falls observed in sweets, baked goods, and cookies. Even staple items like bread, meat, and eggs saw a reduction in spending.
Only a handful of categories witnessed an increase. Yogurt led this small group, followed by fresh fruit, nutrition bars, and meat snacks. "The main pattern is a reduction in overall food purchases. Only a small number of categories show increases, and those increases are modest relative to the overall decline," Hristakeva explained.
Long-Term Implications for Food Industry
The ripple effects of this behavioural shift extend far beyond individual budgets. The sustained drop in spending on snack foods and fast food signals potential long-term changes in market demand.
This trend could force food manufacturers, restaurants, and retailers to reconsider their strategies. Product formulations, package sizes, and marketing approaches may need to evolve to align with the new consumption patterns driven by the widespread adoption of GLP-1 drugs.
The research underscores a profound shift: these medications are not just medical tools but agents of significant behavioural and economic change. As their use grows globally, including in countries like India facing rising obesity rates—890 million people lived with obesity worldwide in 2022 according to the WHO—their impact on lifestyle and commerce will likely deepen.
