The Claim
In men with early type 2 diabetes, Black African men have no significant difference in whole-body, skeletal muscle, hepatic, or adipose tissue insulin sensitivity compared to White European men, despite differences in visceral fat mass and skeletal 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.
Among men with early type 2 diabetes, Black African men and White European men show the same level of insulin sensitivity in the body, muscles, liver, and fat tissue, even though Black African men have less visceral fat and more muscle mass.
See the scientific wording
In men with early type 2 diabetes, Black African men exhibit no significant difference in whole-body, skeletal muscle, hepatic, or adipose tissue insulin sensitivity compared to White European men, despite having 34.5% lower visceral fat mass and 11.9% greater skeletal muscle mass, suggesting that ethnic differences in fat distribution do not translate to differences in tissue-specific insulin sensitivity in this population.
In Black African men with early type 2 diabetes, fat tissue releases fatty acids at a rate that does not impair muscle insulin response, unlike in White European men, where those same fatty acids block insulin's ability to move sugar into muscle cells. This means muscle sensitivity to insulin stays normal even when fat distribution differs between groups.
What the research says
1 studyEven though Black African men had less belly fat and more muscle than White European men, their muscles, liver, and fat tissues were just as sensitive to insulin — meaning less belly fat didn’t make them more insulin-sensitive in this group.
