GLP-1s Hit Fast-Forward on This Basket Trend

by Greg Madison

The media is starting to talk about GLP-1 drugs as if they’re the herald of a brand-new kind of shopper. I don’t think that’s the right way to look at it.

What GLP-1s are actually doing is accelerating a set of behaviors that were already taking hold – particularly among younger consumers. That’s forcing retailers and brands to respond a bit faster than they’d expected.

New research from Acosta Group shows consumers using GLP-1s are buying more fresh produce (55%), yogurt (32%) and protein products, while sharply pulling back on sweets (58%), salty snacks (44%) and sugary drinks (41%).

I admit that that reads an awful lot like disruption. In reality… it’s just Millennials and Gen Z.

Indeed, Acosta’s numbers show that these behaviors are strongest among Gen Z and Millennials, suggesting GLP-1s aren’t creating new preferences so much as accelerating ones already taking shape.

What These Younger Consumers Want

Smaller portions. Higher protein intake. More intentional eating. Less impulse-driven consumption. These are emerging behavioral norms that were already reshaping the perimeter of the store. GLP-1s are simply compressing the timeline.

Many report being satisfied with healthier changes – 41% say they’re pleased with the shift, and half say it’s improving their household’s overall eating habits, rising to nearly 80% among Millennials. This isn’t a temporary “diet effect” so much as a behavioral reset.

Yes, fewer items are making it into the basket, but the bar for each item that does is higher. Protein content, nutrient density and functional benefits are moving from “nice-to-haves” to baseline expectations. 

That has direct implications for how stores are merchandised and how categories are structured. The pressure point is the center store.

Where GLP-1’s Impact Shows First

If even a modest share of consumers reduces purchases of sweets, snacks and sugary beverages – categories that still drive a significant share of store economics – the impact compounds quickly. The thing is, the early data is not modest, with those double-digit pullbacks already showing up in sweets, snacks and sugary beverages. 

At the same time, growth is concentrating in more complex, often higher-cost segments: fresh, refrigerated, functional, and protein-centric products.

That’s admittedly a harder mix to execute on. It requires tighter forecasting, better shrink management, and more disciplined assortment decisions. (These are all fantastic use cases for maturing AI and data tools, but that’s a story for a different day.)

So the media narrative that “GLP-1s are a volume risk,” is an overreaction to what’s really a mix shift. 

Consumers may be buying fewer units, but they are increasingly expecting those purchases to deliver specific outcomes. That opens the door to “premiumization” – but only if retailers and brands can meet the expectation with clarity and consistency.

A More Intentional Shopper Emerges

And make no mistake, these consumers are engaged – with a capital “E.” The data shows large majorities report actively researching products and health information. They’re researching to the ends of the Earth, to boot; 70% of GLP-1 users actively research products or health information, often across social media (57%), AI tools (41%) and retailer platforms (38%). 

In other words, this is a more deliberate shopper; they’re less reactive, more informed, and less dependent on traditional promotional cues than the industry is used to. If the products they want are out there, if the outcome they’re desiring is remotely possible, these shoppers will go to great lengths to find it. Retailers that can provide it stand to reap rewards. 

The challenge is that many operating models are still built around volume-driven, promotion-heavy categories that don’t align with this ongoing change.

At the end of the day, GLP-1 usage might yet be contained; there are always limits. But the behaviors associated with it are not.

What the industry is seeing today is a leading indicator that aligns closely with broader generational shifts and is now being reinforced, not created, by medical intervention.

With all that said, I don’t think the answer is building “GLP-1 assortments.” Acosta reports that even “GLP-1-friendly” labeling is proving polarizing, raising questions about taste, nutrition, and relevance. 

The first step on the road to success with these consumers is to recognize that their particular definition of value is changing, moving away from quantity and toward function.
