Circulating Adipocyte Fatty Acid–Binding Protein (A-FABP) levels are significantly elevated in overweight and obese individuals and correlate positively with components of metabolic syndrome, including insulin resistance, dyslipidemia, and hypertension.

This research highlights that Adipocyte Fatty Acid–Binding Protein (A-FABP) is a circulating marker that rises with obesity and correlates with metabolic risks like insulin resistance and high blood pressure. While measuring A-FABP is not a standard clinical test for weight loss, the findings reinforce that excess adipose tissue actively contributes to metabolic dysfunction through secreted proteins. Managing body weight and reducing visceral fat are the primary levers to lower these biomarkers and improve metabolic health.

GoodSupportsHIGH confidence
Mean (SD) circulating concentrations of A-FABP were significantly higher in overweight/obese than in lean persons [32.3 (14.8) vs 20.0 (9.8) (cid:1)g/L; P <0.001]. Age- and sex-adjusted serum A-FABP concentrations correlated positively (P <0.005) with waist circumference, blood pressure, dyslipidemia, fasting insulin, and the homeostasis model assessment insulin resistance index.

Why this rating

Large sample size (n=229), rigorous proteomic identification, and statistically significant correlations, though it is a cross-sectional observational study.
