45% of athletes may be at risk for underfueling and low energy availability (2024 meta-analysis).
Why?
Higher energy demands, pressure to maintain a certain physique, lack of nutrition education, and even appetite suppression from intense training.
This doesn’t just impact performance - it also increases the risk of disordered eating and eating disorders.
So how do we spot underfueling beyond performance declines?
Look for the subtle (and not-so-subtle) physical signs:
- Persistent fatigue (in and out of training)
- Menstrual changes or loss of period
- Frequent illness or injuries
- GI issues (constipation, diarrhea, bloating)
- Trouble sleeping
Athletes are constantly navigating mixed messages about food and body image. That confusion can make it harder to meet their needs.
Recognizing the signs is the first step - so we can actually support them in fueling, performing, and feeling their best.
