New data from Numerator indicates a notable shift in consumer behavior as GLP-1 weight loss medication use continues to expand. The number of households with a current user has doubled since October 2023, reaching 22% of the population. This growth presents both a challenge and an opportunity for the grocery industry as these shoppers adjust their purchasing habits.
Research reveals that GLP-1 users spend 4% less at the grocery store compared to similar households not using the medication. This decline coincides with a shift in basket composition. Shoppers are moving away from traditional pantry staples and carb-heavy items. Instead, they are prioritizing protein, seafood, fiber, and functional nutrition options. While the overall volume of grocery spending is down for this group, these individuals represent over $660 billion in combined spending power across CPG and restaurant sectors.
Retailers are also seeing a change in how these consumers allocate their budgets. Spending is increasing in categories like skincare, fragrances, and various supplements, suggesting that the focus on personal health extends beyond dietary choices. Brands that track these shifts are finding that while interest in GLP-1 drugs is high—with 23% of consumers expressing openness to the medication—the market remains volatile. Data shows that nearly two-thirds of users stop treatment within six months, making long-term loyalty difficult to predict.
For grocers and food companies, the takeaway is clear. Consumers are re-evaluating their relationship with food. Brands that can align their product offerings with a health-conscious, protein-forward mindset will be better positioned to maintain relevance with this growing group of shoppers. As the market for these medications matures, manufacturers must adapt their product development and marketing to meet the specific needs of these health-minded consumers.
