The Claim
In untrained adults undergoing 10–12 weeks of resistance training, total training volume-load, self-reported energy intake, protein intake, age, and BMI exhibit weak correlations (|r| < 0.25) with changes in appendicular lean tissue mass, indicating that these variables are poor predictors of short-term skeletal 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 you're new to lifting weights, things like how much you eat, how much protein you get, how old you are, or your BMI don’t really help predict how much muscle you’ll gain in the first few months.
See the scientific wording
In untrained adults performing 10–12 weeks of resistance training, total training volume-load, self-reported energy intake, protein intake, age, and BMI show weak associations (|r| < 0.25) with changes in appendicular lean tissue mass, suggesting these factors are poor predictors of short-term hypertrophy.
What the research says
1 studyThe study looked at how muscle mass changes after 10–12 weeks of weight training and found that things like age, diet, and how much people trained don’t strongly predict who gains more muscle—just like the claim says.
