Metabolic improvement secondary to weight loss was better in A carriers with a low fat hypocaloric diet.

Our study showed a higher initial weight loss at 3 months after the TT variant of FTO gene (rs9939609). However, the weight loss at 9 and 12 months of BPD was similar in both genotypes with a significant improvement in biochemical parameters and cardiovascular comorbidities.

Obese patients with MS had lower mean GLP-1 levels than those without MS. Glucagonlike peptide 1 levels remained as a preventive factor to develop MS.

Data from our study revealed an association with decreased metabolic and cardiovascular markers in obese females. BMI weight, fat mass, waist circumference, triglycerides, leptin, resistin, and IL-6 serum levels were lower in subjects with A allele than non-A allele subjects.

Carriers of Thr54 allele have a better metabolic response than obese carriers with Ala54Ala genotype, with a decrease of total cholesterol, low-density lipoprotein cholesterol, insulin levels, leptin levels, and homeostasis model assessment for insulin sensitivity.

Background and Aims: The common polymorphism rs9939609 of the fat mass- and obesity-associated gene (FTO) has been linked to obesity. Our aim was to investigate its role in weight loss after the administration of a high-protein/low-carbohydrate diet compared to a standard hypocaloric diet (1,000 kcal/day). Methods: During 9 months, 195 patients were randomly allocated to a high-protein hypocaloric diet (HP diet) and a standard hypocaloric diet (S diet). Results: With the HP diet, BMI (-1.9 ± 1.2 vs. -2.10 ± 1.8; p < 0.05), weight (-6.5 ± 2.1 vs. -10.1 ± 4.1 kg; p < 0.05), fat mass (-3.9 ± 3.2 vs. -6.0 ± 3.4 kg; p < 0.05) and waist circumference (-5.7 ± 5.0 vs. -9.9 ± 5.5 cm; p < 0.05) decreased in both genotype groups (TT vs. AT + AA). With the S diet, BMI (-0.9 ± 1.1 vs. -1.8 ± 1.2; p < 0.05), weight (-3.2 ± 3.0 vs. -9.1 ± 3.6 kg; p < 0.05), fat mass (-3.0 ± 3.1 vs. -5.2 ± 3.1 kg; p < 0.05) and waist circumference (-3.1 ± 4.0 vs. -8.1 ± 4.9 cm; p < 0.05) decreased in both genotype groups. With the HP diet and in both genotype groups, glucose, insulin levels, homeostasis model assessment of insulin resistance (HOMA-IR), total cholesterol, triglycerides and low-density lipoprotein (LDL) decreased. With the S diet, total cholesterol and LDL decreased. Conclusion: Weight loss was better in A allele carriers than noncarriers, and metabolic improvement was better with the HP diet.
