GLP-1 Era Drives Shift Toward Functional Snacking

As GLP-1 medications influence purchasing behavior, convenience retailers are seeing stronger demand for protein-packed, portion-controlled and functional snacks instead of traditional impulse buys.

The rise of GLP-1 medications has caused a ripple effect across the snacking category in the c-store industry — but not in the way you might think. Retailers will still be able to cash in on snacks, but they will need to adapt to shifting lifestyle norms and expectations from health-conscious consumers.

The big winner in 2026 is protein, with retailers consistently citing a notable uptick in demand for products with functional benefits like this. The better-for-you trend in snacking is one that has been intensifying in recent years and shows no sign of slowing down.

“The shift is more subtle than the headlines suggest,” said Sean Carroll, director of category management at Good 2 Go, which operates over 80 c-stores across the U.S. Mountain West region. “What we’re seeing isn’t a collapse in snacking; it’s a rebalancing. GLP‑1 users tend to shop with more intention.”

That shows up, noted Carroll, as smaller basket sizes; fewer impulse grabs at the counter; a move toward single-serve, portion-controlled items; and, of course, an uptick in protein-forward snacks.

“Purposeful, higher‑quality snacking is growing,” he continued.

At Northborough, Mass.-based Yatco, which operates 23 c-stores across Massachusetts, Connecticut and Rhode Island, Category Manager for Center Store Walter Thomas is seeing a similar trend.

“Sales are showing us that customers are seeking healthier and more functional options when shopping at our stores,” said Thomas. “Year over year, we’ve seen notable lifts in categories that align with GLP-1-related behavior shifts, including fresh fruit, yogurt, nuts, meat snacks, protein items, packaged cheese and energy-focused products.”

While Thomas noted that he hasn’t seen “drastic declines” tied directly to GLP-1 usage, some traditional indulgence categories like packaged bakery and select snack segments have softened relative to their healthier alternatives.

“One surprising growth segment for us has been beverage enhancers and hydration products,” he said. “As GLP-1 awareness increases, many consumers are becoming more focused on hydration and electrolyte balance — especially as they adjust eating habits and overall nutrition.”

This is a trend that is extending to retailers across the U.S. At Heath, Ohio-based Englefield Oil, which operates more than 120 Duchess convenience stores, Director of Marketing Nathan Arnold noted that the company is seeing “more intentional snack shopping.”

“The traditional impulse purchase is still there, but there is clearly more interest in snacks that offer a functional benefit, especially protein, hydration, better-for-you ingredients and portion control,” he continued.

It is important to note that c-stores are not losing snacking customers; preferences are simply changing. The king of c-store snacking — the salty segment — has taken the biggest hit, however, there is still room for innovation and success within the segment.

“Salty is declining not because the shopper is leaving the category, but because large‑format bags don’t align with the more intentional, portion‑controlled behavior we’re seeing,” said Carroll. “The mission is still there — the format is what’s shifting.”
