Dr. Nicky Keay, BA, MA (Cantab), MB BChir, MRCP is a physician and researcher with an extensive background in endocrinology and sports/exercise medicine. Her personal background as a ballet dancer and choreographer led to her long-standing interest in the effects of high-level training and inadequate nutrition on women’s health. Her current research focuses on Relative Energy Deficiency in Sport (RED-S), examining the impact of similar factors on male cyclists.
In this podcast with Dr. Tommy Wood, Dr. Keay discusses the detrimental and often permanent impact of low energy availability, especially in weight-sensitive sports in which participants tend to undereat. They discuss the factors involved with RED-S, including diagnosis, intervention and prognosis, as well as the psychological factors that tend to interfere with treatment.
