- High-carbohydrate diets are often recommended for muscle hypertrophy, but their isolated effect is unclear.
- A meta-analysis found no significant effect of carbohydrate intake on muscle hypertrophy during resistance training.
- The analysis included 11 studies with negligible heterogeneity and low certainty of evidence.
- Subgroup analyses (isocaloric trials and direct muscle imaging) also showed non-significant results.
- Study quality ranged from fair to good, but GRADE certainty was low due to imprecision and moderate bias.
- Future research should focus on stricter energy control and direct morphological assessments.
