The Claim
In untrained older men aged 60–75 years who habitually consume at least 1.0 g/kg/day of protein, the addition of 40 g of supplemental protein per day—whether ingested post-exercise or pre-sleep—does not enhance resistance training-induced gains in strength or muscle thickness beyond those achieved with resistance training alone, suggesting that meeting baseline daily protein requirements is sufficient to maximize adaptive responses to resistance training in this population.
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.
Older guys (60–75) who already eat enough protein don’t get stronger or build more muscle from extra protein shakes, even if they drink them after working out or before bed—just lifting weights is enough.
See the scientific wording
In untrained older men aged 60–75 years with habitual protein intake ≥1.0 g/kg/day, adding 40 g of supplemental protein daily—whether consumed post-exercise or pre-sleep—does not further increase resistance training-induced strength or muscle thickness gains beyond those achieved with resistance training alone, indicating that meeting daily protein requirements is sufficient to support maximal adaptive responses to training in this population.
What the research says
1 studyThe study found that older men who already eat enough protein don’t get stronger or build more muscle from taking extra protein after workouts or before bed — just doing the workouts is enough.
