The Claim

Insufficient energy intake can mimic or worsen symptoms of overtraining, even though overtraining can still occur independently despite adequate energy and protein intake.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
3 studies reviewed
In plain English

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.

See the scientific wording

Insufficient energy intake can mimic or exacerbate symptoms of overtraining, but overtraining can occur independently when energy and protein intake are adequate.

What the research says

3 studies
  1. Study: The Commonality of Overtraining Syndrome and Relative Energy Deficit Syndrome in Sports (REDs). Literature Review

    The study shows that not eating enough can look like overtraining, but overtraining can also happen even if you're eating enough, which matches the claim.

  2. Study: Overtraining Syndrome (OTS) and Relative Energy Deficiency in Sport (RED-S): Shared Pathways, Symptoms and Complexities

    The study shows that not eating enough can look like overtraining, but also recognizes that overtraining can still happen even if you're eating enough.

  3. Study: Overtraining Syndrome (OTS) and Relative Energy Deficiency in Sport (RED-S): Shared Pathways, Symptoms and Complexities

    The study shows that not eating enough can look like overtraining, but it also agrees that overtraining can happen even if you're eating enough, which matches the claim.
