The Claim
In healthy middle-aged Japanese women undergoing resistance training, changes in muscle mass are influenced by both baseline protein intake and changes in breakfast protein consumption, where lower initial protein intake and greater increases in breakfast protein over time are associated with greater gains in muscle mass.
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.
If middle-aged Japanese women who are doing strength training start eating more protein at breakfast—especially if they weren’t eating much before—they’re likely to gain more muscle.
See the scientific wording
In healthy middle-aged Japanese women performing resistance training, the relationship between protein intake and muscle mass changes depends on both baseline levels and changes in protein consumption at breakfast, with lower initial intake and greater increases over time being linked to better muscle gains.
What the research says
1 studyThe study shows that women who started with low protein at breakfast and then increased it gained more muscle from resistance training, which matches the claim.
