Background and aims: The C385A polymorphism of FAAH gene (rs324420C > A) has been associated with obesity. We investigate the role of this polymorphism on anthropometric and insulin resistance responses to a high polyunsaturated fat hypocaloric diet. Methods: Obese individuals (no.=99) were assessed at baseline and after 3 months of a high polyunsaturated fat hypocaloric diet. Results: Seventy-one patients (71.7%) had the genotype C385C and 28 (28.3%) patients had the C385A (26 patients, 26.3%) or A358A (2 patients, 2.0%) (A allele carriers group) genotype. In A allele carriers and after dietary intervention, total cholesterol (-16.3 +/- 37.4 mg/dl) and LDL-cholesterol (-12.9 +/- 6.5 mg/dl) levels decreased. In subjects with C385C genotype, the decreases were significant in total cholesterol (-12.3 +/- 27.4 mg/dl), LDL-cholesterol (-7.5 +/- 20.5 mg/dl), insulin (-2.2 +/- 6.2 mUI/l), and homeostasis model assessment of insulin resistance (HOMA-R) (-0.79 +/- 1.15 units) levels. The weight loss was similar in both genotype groups (-4.1 +/- 3.8 kg vs -4.2 +/- 3.2 kg). Only leptin levels had a significant similar decrease in both genotypes. Conclusion: Subjects with C385C genotype of the FAAH showed an improvement on insulin and HOMA-R levels with a high polyunsaturated fat hypocaloric diet after weight loss during 3 months.
