How GLP-1s Are Reshaping Consumer Behavior

It’s been about a month since FNCE 2025 in Nashville, and I’m still sifting through my notes and revisiting the sessions I loved. One that stood out was the panel “The GLP-1 Effect: Understanding Consumer Behavior Shifts and Their Impact on Food, Nutrition, and Innovation.”

The sheer scale of GLP-1 adoption and the depth of the data presented were striking. What made the session even more compelling was its interdisciplinary perspective, bringing together insights from industry leaders, physicians, RDs, and AI-generated consumer modeling.

GLP-1 medications are reshaping metabolic health, culture, consumer expectations, and the future of the food landscape. Here are some of the key insights that caught my attention.

Shifting Patterns in GLP-1 Use

An estimated 12% of Americans have tried a GLP-1, and projections suggest that 1 in-4 may use one in the near future. Gen Z is leading this surge, turning to these medications not only for chronic disease management but also for perceived wellness benefits, increased energy, and changing body ideals.

The motivations behind GLP-1 use are continuing to shift. Although these medications were originally developed to address diabetes and cardiovascular risk, about 40% of consumers now report using them primarily for “cosmetic” related weight loss.

Inside the AI-Modeled GLP-1 Consumer

Panelist Amanda Patterson, Senior Vice President of Strategy and Intelligence at FleishmanHillard, introduced an AI agent built from more than 5,000 data points. This tool synthesized a wide range of information to create a representative model of GLP-1 users, allowing the research team to examine their shared characteristics, motivations, and preferred approaches to education and engagement across different practice settings.

AI-Modeled “Consumers”: Alexis and Layla

Researchers interacted with AI-generated “patients” to observe how different GLP-1 users respond to messaging, express concerns, and make decisions. The simulation made one point very clear: every consumer behaves differently, and one-size-fits-all guidance will not work.

- The strongest determinants of engagement and trust included cost, access to knowledgeable and respectful providers, and culturally relevant care, which was particularly important for Black and Hispanic consumers.
- Gender also shaped motivations. Men tended to frame their goals around performance and health, while women focused more on appearance and confidence.
- GLP-1 users preferred plain language over medical jargon. They are highly digitally engaged, and they are already searching, self-educating, and joining online communities.
- While social media plays a role in curiosity, the most trusted sources remain reputable medical websites, reflecting a strong desire for credible, science-based information.

From this exercise, the researchers were able to develop two representative patients. Meet Alexis and Layla.

The Ripple Effects of GLP-1 Use

GLP-1 use is reshaping daily life in ways that extend far beyond individual health outcomes and into family dynamics, community behaviors, and even broader cultural norms and ideals.

Researchers note that families often adapt together as eating patterns shift, social events become less food-centered, and simple, structured routines like weekly meal planning become more common.

There are also shifts in broader cultural trends. A new aesthetic ideal of “effortless slimness” is emerging, and emotions such as fear, hope, shame, and excitement are playing a strong role in decision-making. Many GLP-1 users report feeling vulnerable or hesitant when seeking nutrition guidance.

GLP-1 Driven Food and Nutrition Trends

One of the most striking statistics shared during the session was that an estimated 45 billion calories per week have effectively disappeared from the US diet as more people begin or continue GLP-1 therapy.

The food and wellness industry is already responding to this shift, rapidly expanding high-fiber and high-protein offerings and developing products formulated to support satiety with ingredients such as protein isolate, glutamine, creatine, probiotics, polyphenols, and fiber.

Many brands are beginning to label items as “GLP-1-friendly,” “satiety-supporting,” or “hormone-aligned,” and there is growing investment in portion-controlled and single-serve products that reflect reduced appetite and smaller meal sizes.

While these changes signal quick adaptation, the session emphasized that brands need to move beyond simplified or “diet culture lite” marketing. The real opportunity lies in prioritizing nourishment, metabolic health, and long-term health.

A Call to Action for Healthcare Professionals

For registered dietitians and diabetes care and education specialists, this moment is a call to step forward. We are uniquely positioned to provide evidence-based guidance, lead online communities, partner with brands, advocate for access, and help close the widening education gap.

This session affirmed something I see in my own practice. Nutrition professionals are not optional in the GLP-1 era. We are essential to helping individuals navigate the metabolic, emotional, and cultural shifts that accompany these therapies and to supporting safe and effective outcomes.
