Plasma levels of the adipokine omentin-1 are significantly decreased in obese and overweight individuals compared to lean individuals, and these levels are inversely correlated with BMI, waist circumference, and insulin resistance.

This research identifies omentin-1 as a biomarker that drops as you gain visceral fat and become insulin resistant. While there is no current clinical test for omentin-1, this finding reinforces that reducing visceral fat (through caloric deficit and exercise) is likely to restore healthy adipokine profiles, including omentin-1, which may improve insulin sensitivity.

GoodSupportsHIGH confidence
Lean subjects had significantly higher plasma omentin 1 levels than obese and overweight subjects... Plasma omentin 1 levels were inversely correlated with BMI, waist circumference, leptin levels, and insulin resistance as measured by homeostasis model assessment.

Why this rating

Study uses a well-characterized, genetically homogeneous population (Amish) with rigorous statistical adjustments for family structure, age, and sex, though it is observational.
