Is RED-S a Hot Topic or Still Hiding in Plain Sight?
Many female athletes are unknowingly putting both their health and performance at risk.
Relative Energy Deficiency in Sport (RED-S) occurs when an athlete’s energy intake doesn’t meet the demands of their training and recovery. It’s not just about being tired or feeling off. RED-S can lead to:
- Chronic fatigue
- Increased injury risk
- Menstrual dysfunction
- Bone density loss
- Mental health challenges
A 2023 study published in the European Journal of Sports Science investigated 60 elite players from three Norwegian football teams. The results were concerning: 22% were identified as being at risk of RED-S.
So why aren’t we talking about this more?
For too long, damaging narratives have dominated sport:
“Lighter means faster”
“Pushing through fatigue makes you stronger”
These messages are not just outdated—they’re dangerous.
The truth!
Under-fueling doesn’t just reduce performance. It can shorten careers and cause long-term health issues.
So, what needs to change?
- Coaches & Support Staff
Must recognise the signs of RED-S and create a culture that prioritises fueling, rest, and recovery. - Athletes
Need to understand that eating enough is not a weakness—it’s a competitive advantage. - Sports Media & Fans
Should challenge harmful ideals and stop glorifying unsustainable body standards.
The Good News?
Awareness is growing. But we’re not there yet. We need more open conversations, better education, and concrete action to protect athletes (especially women) from the hidden toll of RED-S.
Let’s set a new standard in sport: one where fueling right is part of playing well.
