Visceral fat has more insulin receptors and responds more strongly to insulin than subcutaneous fat.
See the scientific wording
Visceral adipose tissue expresses a higher density of insulin receptors and exhibits greater insulin sensitivity than subcutaneous adipose tissue.

Cross-Sectional StudyHuman2022
This study found that belly fat in obese people produces molecules that make the body less responsive to insulin, meaning it’s actually worse at using insulin — not better. So it contradicts the idea that belly fat is more sensitive to insulin than other fat.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
Fat around the organs has more insulin receptors than fat under the skin, so it takes up more glucose when insulin is present.

Visceral fat has more insulin receptors and responds more strongly to insulin than subcutaneous fat.
Mechanism
1 studyFat around the organs has molecules that block insulin from working properly, making it less able to take in sugar than fat under the skin. This contradicts the idea that organ fat is more sensitive to insulin.
Fat around the organs has more insulin receptors than fat under the skin, so it takes up more glucose when insulin is present.
Visceral adipose tissue expresses a higher density of insulin receptors on the surface of adipocytes compared to subcutaneous adipose tissue
Increased insulin receptor density enhances insulin binding and activation of the insulin signaling cascade in visceral adipocytes
Enhanced insulin signaling increases translocation of GLUT4 glucose transporters to the plasma membrane in visceral adipocytes
Greater GLUT4-mediated glucose uptake occurs in visceral adipose tissue compared to subcutaneous adipose tissue
Less supported by current evidence, but not ruled out
Certain microRNAs in belly fat block the insulin response, making it less able to take up glucose.
Elevated expression of miR-143 and miR-34a in visceral adipose tissue inhibits key insulin signaling proteins
Inhibition of insulin signaling proteins reduces GLUT4 translocation and glucose uptake in visceral adipocytes

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
