The Claim
In young, healthy men undergoing 10 days of 40% energy restriction, a protein intake of 2.4 g/kg/d attenuates the decline in muscle protein synthesis compared to a protein intake of 1.2 g/kg/d, but does not prevent it.
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.
In young, healthy men on a calorie-restricted diet for 10 days, consuming 2.4 grams of protein per kilogram of body weight per day reduces the loss of muscle protein synthesis compared to consuming 1.2 grams per kilogram per day, but does not stop it entirely.
See the scientific wording
In young, healthy men, elevated protein intake (2.4 g/kg/d) during 10 days of 40% energy restriction does not prevent the decline in muscle protein synthesis but attenuates it compared to lower intake (1.2 g/kg/d), suggesting that while protein alone is insufficient to fully maintain anabolism, it provides a partial protective effect.
When the body gets less energy from food, muscle building slows down because the system that makes new proteins runs low on fuel. But when more protein is eaten, the extra amino acids keep this system partially active, so muscle building doesn't drop as much as it would with less protein.
What the research says
1 studyWhen people eat less food but more protein, their muscles still build less than normal — but they build a bit more than if they ate less protein. So more protein helps a little, but doesn’t fully stop the drop.
