Low energy availability in athletes, or Relative Energy Deficiency in Sport (RED-S), is chronic under-fueling while consistently overtraining. RED-S is not an eating disorder, but can impact training performance and reproductive health, compromise bone health, impact cognitive health and mental illness, and decrease cardiac health. Body weight alone is not an indication of RED-S, and both men and women are susceptible.
