On October 14th, 2025, the KHNI hosted an expert scientific webinar; “Adapting Appetites: Scientific and Industry Perspectives on the rise of GLP-1 Medications”. The expert panel explored the latest science behind Glucagon Like Peptide-1s (GLP-1s), consumer behaviors across regions, the unique nutritional needs of users and what this means for future innovation in food and beverages.
Latest Scientific Insights on GLP-1s
Professor Catherine Godson, Professor of Molecular Medicine, University College Dublin (UCD) and Director of the UCD Diabetes Complications Research Centre, began her session discussing the evolution of GLP-1s which were initially indicated for people with type 2 diabetes. Given that GLP-1s result in weight loss, the next approach was to explore if they had a positive effect on people with obesity. Professor Godson highlighted GLP-1 established indications as well as other indications that are under investigation. Interestingly, Catherine pointed out that the incretin hormone GLP-1 not only acts on the cells in the pancreas but also in other areas of the body such as the brain. Professor Godson concluded her session addressing the efficacy, safety and tolerability of GLP-1s.
Regional Trends in GLP-1 User Behavior
Elizabeth Horvath, VP of Marketing for Kerry North America, took us through findings from GLP-1 consumer surveys conducted by Kerry in the US (quantitative survey) and the UK (qualitative survey). The quantitative survey looked at GLP-1 users’ purchase drivers and preferences whereas the qualitative survey explored GLP-1 user habits throughout the entire day to understand their daily activities. Elizabeth highlighted there were five very specific GLP-1 consumers, each on their own health journeys, and that their attitudes and behaviors shift at every stage of the GLP-1 journey. Interestingly, the North America study showed that two-thirds of GLP-1 users are actively seeking functional benefits from their food, beverages, and supplements. Among their top priorities are support for cognitive function, digestive wellness, and immune health. Elizabeth shared insights into how GLP-1 users’ buying habits are changing, especially in foodservice and retail.
Nutrition Essentials for GLP-1 Users
Next, Angie Jefferson focused on the nutritional needs of GLP-1 users. Initially, Angie introduced the different GLP-1 medications on the market. Currently, there are few good quality trials exploring the impact of GLP-1 medication on consumer eating habits, dietary intakes, and/or their impact on nutritional status. Angie pointed out that a much higher proportion of weight loss in GLP-1 users is attributed to loss of lean body mass; however, GLP-1 use combined with resistance exercise can help preserve or increase muscle mass. Angie provided insights into the nutritional status and emerging needs of GLP-1 users. She also noted that discontinuing GLP-1 treatment often leads to weight regain, with a tendency toward increased body fat percentage. Angie wrapped up by stressing an urgent gap exists in dietary and lifestyle guidance for GLP-1 users.
Innovation Opportunities in Food & Drink for GLP-1 Users
Dr Alexandra Boelrijk, Kerry VP R&D ProActive Health and Food Protection, looked at opportunities and challenges when considering products for GLP-1 users. Alexandra pointed out that the food and beverage companies early to market with products that meet demands of various GLP-1 users have opportunities to defend share as well as drive growth. Dr Boelrijk highlighted that forward-thinking brands are addressing the needs of GLP-1 users by reformulating products with higher protein, fiber, and micronutrients and/or by developing functional foods that support gut health, satiety, and metabolic support. Alexandra concluded by discussing the new formats of products that have launched in the market for GLP-1 users.
During the Q&A session, moderator Mark Faherty posed thoughtful questions to the speakers. He concluded the webinar by expressing gratitude to Angie, Alexandra, Catherine, and Elizabeth for sharing their time and expertise.
