The Claim
In elderly men over 70 years of age, a protein intake of 1.6 g/kg/day for 10 weeks results in an increase in trunk lean mass of approximately 1.39 kg greater than a protein intake of 0.8 g/kg/day under conditions of moderate negative energy balance.
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.
Among men over 70, consuming 1.6 grams of protein per kilogram of body weight daily for 10 weeks leads to 1.39 kilograms more trunk lean mass gain than consuming 0.8 grams per kilogram daily, even when both groups are in a moderate calorie deficit.
See the scientific wording
In elderly men over 70, a protein intake of 1.6 g/kg/day for 10 weeks increases trunk lean mass by approximately 1.39 kg more than a 0.8 g/kg/day intake, despite both groups being in a moderate negative energy balance.
When elderly men eat more protein, their blood carries more amino acids, especially leucine, which turns on a cellular switch that tells muscle cells to build more protein. This happens even when they are eating fewer calories than they burn. Over time, the muscle cells make more protein than they break down, so their trunk muscles grow larger.
What the research says
1 studyEven when older men ate fewer calories than they burned, those who ate twice as much protein gained more muscle in their torso than those who ate the standard amount. Protein helped them keep and build muscle, even on a diet.
