Big Food companies are moving to shorter ingredient lists and smaller pack sizes in 2026
GLP-1 drugs are cutting average calorie intake by 40 percent among users, with dessert consumption down 84 percent and fresh produce intake up more than 70 percent, according to PwC analysis cited by Reuters.
That kind of shift is already forcing food manufacturers and restaurant chains to rethink what they sell, how much they serve and where they invest.
Smaller portions, “protein-forward” products and portfolio shake-ups are moving from niche to mainstream.
Global food and beverage companies from PepsiCo to Coca-Cola are moving to shorter ingredient lists and smaller pack sizes in 2026 as more people take GLP-1 drugs for weight loss, according to Reuters.
Companies that once took a wait-and-see approach now treat GLP-1s as a durable force: nearly three dozen non-healthcare firms have mentioned GLP-1 drugs or weight loss on earnings calls so far this year, up from 14 a year earlier and just five two years before.
Diet changes linked to GLP-1 use could erase up to US$12bn in snack sales over the next decade, according to EY-Parthenon estimates reported by Reuters.
Adoption of GLP-1 drugs more than doubled in the 12 months to December, with about 20 percent of US households now including at least one user, as per the PwC analysis.
PwC’s look at Numerator data found that GLP-1 users on average consume 40 percent fewer calories, with dessert consumption down 84 percent and alcohol use down 33 percent, while fresh produce intake is up more than 70 percent.
Family grocery baskets are 4 percent to 6 percent smaller, and single-person households have seen declines of up to 9 percent.
Peter ter Kulve, CEO of Magnum Ice Cream, told Reuters that GLP-1 users still eat treats but show “a stark reduction of mindless munching and binge eating.”
PwC US consumer markets leader Ali Furman said, “We’re just starting to scratch the surface on the ripple effects of this type of physiological disruption,” as reported by Reuters.
Manufacturers are not standing still.
PepsiCo has launched a “Simply NKD” line to reformulate snacks and is rebranding Lay’s and Gatorade by removing artificial colours.
PepsiCo will also test mini-meal options with its Sabra and Siete brands in the US, CEO Ramon Laguarta said at the CAGNY conference, adding, “I think there are more opportunities than threats, but there are both,” on a recent post-earnings call.
Coca-Cola ramped up production late last year to meet growing demand for its protein-infused Fairlife milk.
General Mills launched higher protein Cheerios cereal in December 2024 as it faces breakfast competition.
General Mills CEO Jeffrey Harmening told investors at CAGNY that he expects GLP‑1 and other anti‑obesity drugs to have “a lasting influence in the food and nutrition landscape.”
He said they are nudging some consumers towards “smaller portions and more nutrient-dense protein and fiber-forward foods.”
Capital expenditure is rising to support these shifts.
Capex is expected to increase for most large food companies this year, jumping as much as 23 percent for General Mills, based on LSEG data cited by Reuters.
Kraft Heinz’s new chief stopped a planned split and instead announced US$600m in investments this year to revive long-neglected staples such as Oscar Mayer meat and cold cuts.
Conagra Brands is investing in snacks such as Slim Jim meat sticks, nuts and seeds, and last year issued a report highlighting rising demand for “protein-forward, portion-controlled and nutrient-dense” foods, especially among Gen Z and millennials.
Smaller players see similar openings.
Snap Kitchen, a private Austin-based company serving roughly 35,000 customers annually, expanded its menu with higher fibre, lean protein density and satiety-promoting ingredients, CEO Mitchell Raisch said. “The GLP-1 opportunity has sharpened our focus and accelerated our pipeline,” he told Reuters.
“There’s not anyone out there that’s not designing, putting R&D dollars against this trend,” said Peter Mangan, managing director at Portage Point Partners.
