The Claim
In healthy young and elderly men, ingestion of carbohydrates alone after simulated daily activities results in negative whole-body protein balance, indicating net muscle protein breakdown.
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.
When healthy young and elderly men consume only carbohydrates after physical activity, their bodies break down more muscle protein than they build.
See the scientific wording
In healthy young and elderly men, ingestion of carbohydrates alone after simulated daily activities results in negative whole-body protein balance, indicating net muscle protein breakdown.
When only carbohydrates are consumed after physical activity, the body does not receive the signal to build new muscle proteins. Without this signal, muscle proteins continue to break down faster than they are made, leading to a net loss of muscle protein.
What the research says
1 studyWhen healthy men ate only carbs after light activity, their bodies broke down more muscle protein than they built. Adding protein and leucine fixed this — but carbs alone caused muscle loss.
