The Claim
Protein supplementation is probably associated with increased muscle strength in athletes, with a standardized mean difference of 0.72 compared to placebo, but only in trials where energy intake was not equated between groups; this suggests that the observed strength gains may be attributable to greater total energy intake rather than protein-specific anabolic effects.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Athletes taking protein might get stronger, but it could just be because they're eating more total calories — not because of the protein itself.

What the research says
1 studyThe study found that protein supplements seemed to help athletes get stronger, but only when they were eating more total calories. This suggests the extra strength might come from eating more food overall, not just from the protein.
