Despite growing awareness of disordered eating in female populations, the presentation of disordered eating in males-particularly in athletic and tactical populations-remains significantly underrecognized and undertreated. Male athletes and military service members operate in high-pressure environments that prioritize leanness, strength, ands endurance. These expectations often foster a culture of normative behaviors that mask serious psychological and physiological distress. Consequently, disordered eating behaviors may be overlooked, misclassified as 'discipline' or 'grit,' or normalized within the subculture. This presentation will explore the unique clinical presentation of disordered eating in male high-performance populations, including differences in symptom expression, risk factors, and help-seeking behaviors. Unlike the thin ideal often seen in female populations, males may pursue leanness, or muscularity through excessive training, dietary restriction, supplement misuse, or cyclical bulking and cutting-all of which can contribute to serious physical and psychological harm. Additionally, trauma, and occupational demands interact to increase risk and contribute to low treatment utilization and poor symptom recognition-even among trained providers. Drawing from both clinical experience and emerging research in sports and military psychology, the session will present a comprehensive framework for understanding and addressing disordered eating in male clients. We will review assessment tools that are better suited to identifying risk in males, discuss indicators that are often missed by traditional screening instruments, and explore how trauma-informed, performance-aligned language can reduce defensiveness and increase engagement. Special attention will be given to the role of interdisciplinary collaboration-particularly between dietitians, therapists, coaches, and medical professionals-in breaking through stigma and supporting early intervention. Participants will learn practical strategies for tailoring assessment and treatment approaches to the specific demands of athletic and tactical environments, where performance is prioritized and disclosure is often discouraged. Case examples will be used to illustrate how disordered eating may emerge and persist in these populations, as well as how providers can support behavior change while respecting the identity, goals, and occupational context of the client. The session will also explore how to assess laboratory values and energy availability while fostering empathy and connections to improve engagement in care. By the end of this session, attendees will be better equipped to recognize disordered eating in male athletes and tactical personnel, apply assessment techniques that reflect their lived experiences, interpret laboratory findings, and provide affirming care that supports both performance and psychological well-being. This session is appropriate for dietitians, therapists, physicians, athletic trainers, and others working with high-performance male populations in clinical, athletic, or military settings.
