Proper energy availability is foundational to athletic performance, training adaptation and overall health. Relative Energy Deficiency in Sport (REDs) occurs when an athlete’s dietary energy intake is insufficient to support the energy expenditure required for daily living and physical training.
When energy availability is compromised, it can affect multiple physiological systems, including metabolic rate, menstrual function, bone health, immunity, protein synthesis and cardiovascular health. Understanding and addressing REDs is critical to ensuring long-term athletic durability, recovery and overall performance.
