The Claim
In middle-aged Japanese women participating in a 16-week progressive resistance training program, higher baseline protein intake at breakfast is associated with smaller increases in whole-body lean soft tissue mass, whereas increases in breakfast protein intake over the course of the program are associated with greater gains in muscle mass, suggesting that modifying the distribution of protein intake at breakfast may influence resistance training-induced muscle hypertrophy.
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 eat more protein at breakfast over time while strength training, they may gain more muscle — but if they already eat a lot of protein at breakfast to start with, they might not gain as much.
See the scientific wording
In middle-aged Japanese women undergoing a 16-week progressive resistance training program, higher baseline protein intake at breakfast is associated with smaller gains in whole-body lean soft tissue mass, while increases in breakfast protein intake over time are associated with greater muscle mass gains, suggesting that adjusting protein distribution at breakfast may influence training-related muscle hypertrophy.
What the research says
1 studyThe study shows that women who started with low protein at breakfast but increased it during training gained more muscle, while those who already ate a lot of protein at breakfast didn’t gain as much. This supports the idea that changing breakfast protein helps muscle growth.
