Stable mass with a concerning underfueling pattern
An endurance athlete reports stable body mass but repeated bone-stress problems, fatigue, and difficulty completing training. The athlete is male and initially believes REDs cannot apply to him. His class schedule overlaps with dining service, and low appetite after morning training leads to missed recovery intake. He does not report a deliberate weight-loss goal. A coach asks for a body-fat number to decide whether unrestricted participation is safe. The athlete is worried that discussing food difficulties could affect selection. The dietitian needs to assess possible low energy availability, provide practical nutrition intervention, protect sensitive information, and coordinate the relevant clinical and training decisions without declaring a diagnosis or clearance from a single number.
1. What should the assessment and nutrition intervention address?
Read the worked answer
REDs can affect male athletes, and stable mass or absent weight-loss intent does not exclude underfueling. Review actual intake, timing, workload, clinical history, symptoms, and access. Develop feasible portable meals and recovery options, support adequacy, and monitor agreed behaviors and relevant outcomes within coordinated care.
2. How should participation and information sharing be handled?

Participation risk needs the appropriate clinical process with medical responsibility, not a body-fat reading alone. Clarify consent, privacy duties, legitimate sharing, and roles. Use nonjudgmental communication and do not treat the coach’s selection interest as unrestricted permission to disclose clinical details.
