The Claim
In men with early type 2 diabetes, higher skeletal muscle mass in Black African men does not result in greater whole-body or skeletal muscle insulin sensitivity compared to White European men, indicating that skeletal muscle mass quantity alone is insufficient to account for differences in insulin sensitivity between these populations.
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.
Among men with early type 2 diabetes, having more skeletal muscle does not lead to better insulin sensitivity in Black African men compared to White European men, meaning muscle size alone does not explain differences in how the body responds to insulin.
See the scientific wording
In men with early type 2 diabetes, higher skeletal muscle mass in Black African men does not confer greater whole-body or skeletal muscle insulin sensitivity compared to White European men, indicating that muscle quantity alone does not explain insulin sensitivity differences.
In Black African men, fat tissue releases fatty acids at a rate that does not interfere with muscle insulin response, so muscle cells take up glucose normally even with more muscle mass; in White European men, fat tissue releases fatty acids that block muscle insulin signals, reducing glucose uptake regardless of muscle amount.
What the research says
1 studyBlack African men have more muscle than White European men with early diabetes, but their muscles aren’t any better at responding to insulin. So having more muscle doesn’t automatically make insulin work better.
