Relative Energy Deficiency in Sport is exactly what the name implies: a shortage of energy available to keep up with the demands of exercise, on top of essential daily functions like growth, respiration and digestion.
When we underestimate our energy needs, or restrict how much fuel we take in while pushing our bodies in training, we fall into a state of ‘low energy availability’. Over time, our body becomes like a phone on low battery mode, turning off many important but non-essential functions, unable to operate at its peak. Unless we allow our body to fully recharge, we’re short-changing our athletic potential and putting our long-term mental and physical health at risk
We’ve seen firsthand how easily this can happen to any athlete, at any time. Our goal is to help you achieve your best without depleting your body or losing your love for sport. Start by getting to know the signs and symptoms, and check out the FAQs below.
