REZA evidence rating C: Interpret with caution — What does this rating mean?
Limited, mixed or hard-to-translate evidence. Useful as direction, not as a rule.
Methodology
Narrative review
Findings
For muscle gain with limited fat gain, a modest calorie surplus (roughly 10-20% above maintenance) with sufficient protein spread across the day is usually recommended — advice from a narrative review, not a hard prescription.
Limitations
Based on a narrative review of the literature, not a single randomised comparison; the optimal surplus varies per person and training phase.
Practical conclusion for REZA
A moderate calorie surplus with adequate protein is a reasonable starting point for those wanting to limit fat gain while building, adjusted to the individual.
