GLP-1 medications fuel demand for healthier, nutrient-dense foods

The growing adoption of GLP-1 therapies is impacting food choices, with consumers increasingly focusing on nutrient-dense, high-protein, and high-fiber options to support their health. Industry experts note that smaller, convenient options with high nutritional quality are crucial to accommodate users who are eating less. 

Nutrition Insight meets with Ingredion, Fonterra, and Carbery to explore innovation opportunities for the food and nutrition industry as GLP-1s are driving demand for nutrient-dense options in smaller formats. 

“GLP-1s aren’t just changing how individuals eat, they’re reshaping how consumers look at nutrient density of what they consume,” says Nina Guest, senior manager of Global Market Insights at Ingredion.

“As calories decline, nutrient density becomes the primary driver of food choice, especially protein to support muscle maintenance, fiber for digestive health, and reducing sugar to avoid energy swings. The risk isn’t under-eating, it’s under-nourishing.”

She underscores that a reduced food intake can widen gaps in protein, fiber, and key nutrients, particularly at breakfast, when appetite is often at its lowest. “This may also raise the importance of affordable, everyday foods that support balanced nutrition without requiring larger portions.”

Nutrient-dense food demand

Jacqueline van Schaik, lead nutritionist at Fonterra, tells us the rise of GLP-1 therapies is reinforcing a broader shift away from simple calorie counting toward nutrient density, nutrition quality, and product functionality.

“Consumers are increasingly looking for foods that help them feel satisfied, support muscle maintenance, and are easy to tolerate, often in smaller, more convenient formats.”

“From a health perspective, these therapies can support positive outcomes when paired with thoughtful dietary choices. At the same time, there are risks to be mindful of,” she cautions. “Reduced overall intake can make it harder to meet protein and micronutrient needs, and muscle loss has emerged as an area of growing attention if nutrition is not carefully managed.”

Van Schaik cautions that a reduced overall intake can make it harder to meet protein and micronutrient needs, which can result in muscle loss.Van Schaik says this reinforces the importance of nutrition quality, not just reducing calories. She notes that foods that provide complete protein, essential vitamins and minerals, and are easy to consume in smaller portions, like grass-fed dairy, can play a constructive role alongside medical treatment — especially when guided by health care professionals.

Fiona Rawlinson, head of Marketing for Nutrition at Carbery, also sees GLP-1s shifting consumer preferences away from high-fat and high-sugar foods toward high-quality options. In addition to a risk of micronutrient deficiencies, she cautions that lower food intake could also widen health disparities if there is no equal access to overall nutrition support for GLP-1 users.

“It’s not just protein gaps; it’s vitamins, minerals, fiber, healthy fats, and the quality of the entire diet that risks splitting between those who are properly informed by health professionals and those who are not. Access to quality foods also becomes a real socio-economic challenge.”

Spotlight on protein quality

Rawlinson notes that protein quality is key for consumers using weight loss medications, as clarified in Carbery’s “Nourishing the GLP-1 Revolution” positioning paper. This report suggests whey protein can be positioned as a companion ingredient due to its benefits in muscle health and weight management.

“Not all protein is equal — and complete proteins like whey, containing all essential amino acids and the full branched-chain amino acid profile, offer a unique triple‑action benefit that directly addresses several of the risks emerging with widespread GLP-1 use,” she details.

“As a muscle guardian, whey helps protect lean mass during reduced appetite; as a weight defender, it supports healthier weight maintenance when people come off GLP-1s; and as a natural GLP-1 enhancer, it provides short‑term complementary effects on appetite and glucose control.”

Amid a rise in GLP-1 adoption, these mechanisms are increasingly relevant at a population level. “Whey’s triple‑action profile positions it as a meaningful nutritional counterbalance — but it’s only one part of the bigger picture,” she says.

Rawlinson says whey protein can help protect muscle mass, support weight management, and enhance GLP-1 naturally.She adds that ensuring access to nutrient‑dense foods, balanced formulations, and clear guidance will be essential to prevent GLP-1‑driven health gains from becoming unevenly distributed. “Done right, this shift can support more equitable, healthier long‑term outcomes across the board.”

Nutrition quality as a new baseline

As GLP-1 users are making smarter and more intentional choices, Rawlinson urges the food industry to get a lot sharper.

“When you’re eating less, every bite has to count, and consumers are naturally gravitating toward foods that deliver. That means nutrition quality becomes the new baseline — complete proteins like whey, nutrient‑dense ingredients, cleaner formulations, and products that genuinely support muscle, energy, and overall well-being.”

“Consumers are already choosing foods that make them feel nourished, not just ‘full,’ and the brands that win in a GLP-1 world will be the ones that understand nutrition quality, not just nutrition marketing,” Rawlinson advises.

She expects a shift toward smaller, smarter, and more nutritionally efficient formats, for example, in bars, ready-to-drink beverages, and snacks, built around whole‑product performance.

At the same time, Fonterra is not seeing a clear signal that these medications will drive new ingredient regulations or labeling requirements, says Van Schaik.

“Most food companies are understandably cautious about directly referencing medical treatments on-pack.”

“Instead, many brands are focusing on well-established, regulated descriptors such as ‘high protein,’ ‘nutrient-dense,’ or ‘balanced nutrition.’ This approach allows products to remain relevant to evolving consumer needs while staying within existing regulatory frameworks and avoiding high-risk health claims.”

Innovation opportunities

The experts say the growing demand for nutrient-dense foods offers innovation opportunities for the food industry.

Van Schaik says that GLP-1 users are prioritizing high protein and high fiber, and buying more fresh produce, dairy, and nutrition bars. Therefore, she highlights these as “great categories” to innovate in with convenient nutrient-dense formats.

Guest notes GLP-1 users share the same core expectations as the broader population: Food must taste good, have an appealing texture, and fit into daily life.“We expect to see greater emphasis on foods that deliver essential vitamins and minerals alongside protein, as well as increased collaboration with dieticians and health care professionals to help consumers make informed choices while using GLP-1 therapies,” she adds.

Guest adds that broader wellness trends, combined with growing GLP-1 usage, will continue to shape how consumers eat and the specific nutrition they seek. “Ingredion’s proprietary research shows that consumers prioritize dependable fullness, digestive comfort, hydration support, and nutrient density.”

Although breakfast is key for energy and well-being, she highlights that this meal can be a particular challenge for GLP-1 users, due to lower morning appetite. She also says that hydration is harder to maintain with a reduced intake of food and beverages.

“These gaps point to clear opportunities for F&B innovations that help people stay nourished without requiring more volume than they can comfortably consume. Ingredion research shows that F&B choice is driven by nutrition factors like protein and gut health, along with feeling full, satisfied, and great taste.”

Convenience and nutrition

Guest underscores that GLP-1 users are not a single group. She says research by Ingredion has identified multiple behavioral segments with different habits and food needs.

“Across all groups, taste, texture, and convenience remain essential. As intake decreases, enjoyment becomes even more important — every bite needs to deliver both satisfaction and nutritional purpose.”

“Taste and texture become even more critical as meal size and frequency evolve,” Guest continues. “The most successful innovations will pair nutritional purpose with sensory satisfaction using texture contrast, creaminess, crunch, or lighter structures to enhance enjoyment without adding excess calories or volume.”

For example, Ingredion collaborates with partners to design texture systems that enhance the eating experience while prioritizing nutrition and meet the demands of GLP-1 users across the food ecosystem.

“As eating moments become more intentional, brands that deliver balanced nutrition, comfort, and pleasure in compact formats can unlock growth across snacks and ready-to-eat food and beverages without isolating GLP-1 users from the broader consumer base,” Guest concludes.
