Recognition & Treatment of Deficient Energy Intake Among Athletes

A Fact Sheet for Registered Dietitians/Nutritionists working with athletes suffering from an Eating Disorder and/or Relative Energy Deficiency (RED-S).


An Evidence-Based resource from the Disordered Eating and Eating Disorders subunit of SCAN.

"Registered Dietitians (RDs) who work with active people and athletes recognize the deleterious effects of energy deficiency on health and performance. The International Olympic Committee (IOC) introduced the syndrome1, Relative Energy Deficiency in Sport (RED-S), in 2014 to emphasize recognition of risks described in the Female Athlete Triad to include males and various ethnicities. RED-S introduces a hub and spoke diagram to illustrate the interplay of physiologic and psychological dysfunction and morbidity, and utilizes a stoplight (‘Red Light-Yellow Light-Green Light’, representing high-risk, moderate-risk and low-risk athletes, respectively) as a simple means of representing to athletes the general pattern of returnto- play."
