The Claim
Relative energy deficit in sports (REDs) is a proposed contributing factor to the development of overtraining syndrome (OTS) in athletes, although it does not fully explain OTS, with other potential mechanisms including cytokine dysregulation, oxidative stress, and central nervous system fatigue.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
See the scientific wording
Relative energy deficit in sports (REDs) is one of the proposed reasons for the development of overtraining syndrome (OTS) in athletes, alongside other theories such as cytokine dysregulation, oxidative stress, and central nervous system fatigue, suggesting that REDs may contribute to but does not fully explain OTS.
What the research says
1 studyThe study says low energy in athletes can contribute to overtraining, but it's not the only cause—just like the claim says.
