REDs, or Relative Energy Deficiency in Sport, occurs when your body doesn’t get enough energy from food to fuel both the demands of exercise and essential daily functions like breathing, digestion, and repairing tissues.
Think of it like running your phone on low battery, where non-essential functions start shutting down. Over time, this can lead to serious physical and mental health problems and limit your ability to perform at your best.
