The Claim

In Black African men with early type 2 diabetes, hepatic insulin sensitivity is negatively correlated with visceral fat mass (r = −0.55, p = 0.04), while no significant correlation exists between hepatic insulin sensitivity and visceral fat mass in White European men with early type 2 diabetes (r = −0.23, p = 0.50).

Source: Black African men with early type 2 diabetes have similar muscle, liver and adipose tissue insulin sensitivity to white European men despite lower visceral fat

In plain English

In Black African men with early type 2 diabetes, higher amounts of visceral fat are associated with lower liver insulin sensitivity, but this relationship does not occur in White European men with early type 2 diabetes.

See the scientific wording

In Black African men with early type 2 diabetes, hepatic insulin sensitivity is negatively correlated with visceral fat mass (r = −0.55, p = 0.04), but this relationship is not observed in White European men (r = −0.23, p = 0.50), suggesting a unique link between liver insulin sensitivity and visceral fat in this ethnic group.

Why this might work

In Black African men with early type 2 diabetes, excess fat around the organs releases fatty acids that flood the liver, where they build up and block insulin's ability to control blood sugar. This link does not happen in White European men, whose livers do not accumulate fat from visceral fat in the same way.

  1. Study: Black African men with early type 2 diabetes have similar muscle, liver and adipose tissue insulin sensitivity to white European men despite lower visceral fat

    In Black African men with early diabetes, more belly fat is linked to worse liver function, but this link doesn’t show up in White European men — the study found this exact pattern.
