Are low energy and overtraining the same problem?
The Commonality of Overtraining Syndrome and Relative Energy Deficit Syndrome in Sports (REDs). Literature Review
Not medical advice. For informational purposes only. Always consult a healthcare professional. Terms
Some athletes get too tired from training too much, but sometimes it's because they don’t eat enough. This study looks at whether not eating enough (called REDs) is just one type of overtraining or a separate issue.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Max 100Randomized Controlled Trials
Max 90Cohort Studies
Max 72Case-Control Studies
Max 58Cross-Sectional Studies

Based on clinical experience or non-systematic literature reviews. The lowest level of evidence as they are most susceptible to bias and personal perspective.

Overtraining in athletes might actually show up as low energy from sports, meaning that 'low energy' could just be one way overtraining looks, not a totally different problem.
Low energy levels in athletes might help explain why some get overtraining syndrome, but it's not the only reason — other factors like brain fatigue and body inflammation could also play a role.
Not eating enough calories can make you feel like you're overtraining, but you can still overtrain even if you're eating enough food and protein.
