In parallel with the above studies, the increase in serum LECT2 levels was also found in population with obesity and fatty liver, which was positively correlated with all the four major anthropometric measures in both males and females, including BMI (body mass index), WC (waist circumference), WHR (waist‐to‐hip ratio) and W/Ht (waist‐to‐height ratio).29 Here, LECT2 is linked to obesity due to melanocortin 4 receptor deficiency.
