Quick start
Start here
Recognize Relative Energy Deficiency in Sport before it causes lasting damage.
Start here
RED-S begins when fuel does not cover training plus normal body function
- The body pays for underfueling by cutting back on hormone function, bone building, recovery, and immunity.
- This is not just about food choices. It is about total energy availability across the week.
Coach red flags
Look for clusters, not isolated bad days
- Constant exhaustion, stalled progress, repeat illnesses, or slower recovery between sessions are common first signals.
- Recurring bone stress injuries or pain in low-risk areas should raise the urgency immediately.
Vital sign
Menstrual function is one of the clearest windows into adequate fueling
- A regular cycle is not a performance inconvenience. It is a health signal.
- Missing three or more cycles, cycles longer than 35 days, or no cycle by age 15 deserve referral.
Watch for
What to watch before it becomes a crisis
Performance drop-offs, stress injuries, menstrual disruption, and persistent fatigue rarely show up as isolated issues.
- Under-fueling is often quieter than coaches expect.
- The best first move is usually a food-plus-screening conversation, not a supplement guess.
- Parents and coaches should hear the same short message.
Performance and training
- Workouts feel harder than they should
- Recovery between sessions gets worse, not better
- Pace or power declines even while training load stays high
