A Practical Guide to Understanding and Preventing Relative Energy Deficiency in Sport (REDs) for Athletes, Coaches, and Parents Grayson Mast * Project Mentor(s): Kelly Pritchett, PhD Relative Energy Deficiency in Sport (REDs) is a condition caused by low energy availability (LEA), where energy intake is insufficient to support the physiological demand of training and daily functioning. REDs can negatively impact multiple body systems like reproductive, endocrine, skeletal, cardiovascular, and immune function, ultimately impairing both health and athletic performance. Despite its prevalence among athletes, many athletes, coaches, and parents lack awareness and knowledge to recognize early signs of REDs or fully understand its impact. The purpose of this project was to develop an evidence-based educational manual to improve awareness, understanding, and prevention of REDs among athletes, coaches, and parents. To support the development of the manual content, current literature was reviewed, including the IOC consensus statement, research on nutrition education interventions, and guidance from three nutrition professionals. The manual is organized into six key sections: sports nutrition foundations, understanding REDs, prevention and early recognition, body image and disordered eating, role-based guidance for coaches, parents, and athletes, and practical tools and resources. The manual incorporates visual aids, fueling strategies, screening tools, and actionable recommendations to support application in real-world settings. This project addresses a gap in accessible REDs education by providing a practical, easily accessible resource for those directly influencing athlete fueling and health. By increasing awareness and knowledge of REDs, this manual aims to promote adequate fueling, reduce risk of REDs, and support long-term athlete health and performance Presentation Type: Pre-Recorded Presentation (https://www.youtube.com/@cwusource5518) Keywords: REDs, Low Energy Availability, Athlete, Education SOURCE Form ID: 56 Project Mentor(s): Nicole Stendell-Hollis, PhD; Kelly Pritchett, PhD; Charlene Mize; Jessica Tyrrell Glucagon-like peptide-1 (GLP-1) receptor agonist medications are becoming an increasingly popular treatment for the management of overweight and obesity. These medications, including Semaglutide, have demonstrated significant weight loss effects in clinical trials and real-world settings. In addition, many patients report a reduction in “food noise,” a newly defined construct referring to persistent and intrusive thoughts about food; yet, there is little research in this area. The aim of this study is to compare food noise levels among adults actively attempting weight loss who are either using or not using GLP-1 receptor agonists. Data collection is currently ongoing. This study uses a cross-sectional, observational, between-subjects design and collects data through an online survey. Adults aged 18 years and older, who are currently attempting weight loss are being recruited through online platforms. Participants complete a validated food noise questionnaire along with demographic and weight management information, including self-reported GLP-1 receptor agonist use. Food noise scores will be compared between GLP-1 users and non-users to determine whether medication use is associated with differences in reported food noise. This research aims to provide evidence regarding the behavioral and cognitive experiences associated with GLP-1 receptor agonist therapy and may contribute to a better understanding of mechanisms influencing adherence and weight management outcomes.
