The Claim
A habitual protein intake of approximately 1.1 grams per kilogram of body weight per day is associated with greater skeletal muscle mass gains in previously untrained older women undergoing resistance training, compared to lower intakes, with a statistically significant threshold identified between 0.9 and 1.3 g/kg/day.
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 previously untrained older women doing resistance training, consuming about 1.1 grams of protein per kilogram of body weight daily is linked to larger increases in muscle mass than consuming less protein, with the clearest benefit occurring between 0.9 and 1.3 grams per kilogram per day.

When older women lift weights, their muscles break down and rebuild. Eating enough protein gives the body the building blocks it needs to make new muscle fibers, and 1.1 grams per kilogram of body weight provides the right amount to maximize this process.
What the research says
1 studyFor older women just starting weight training, eating about 1.1 grams of protein per kilogram of body weight each day helps them build more muscle — and this study found that’s the sweet spot between 0.9 and 1.3 grams.
