| Popis: | Objective: Elevated triglyceride-rich lipoproteins (TRL), excess small dense LDL particles (LDL5) and decreased HDL2/HDL3 ratio promote atherogenesis in type 2 diabetes (T2D). Carbohydrate restriction reduced intrahepatic triglyceride (IHTG) content beyond the positive effect of weight loss in a group of T2D patients, the present study sought to determine whether parallel improvements in lipoprotein density profiles occurred in these same patients. Research Design and Methods: Seventy-two adult T2D patients with a mean BMI of 33 kg/m2 were assigned to 6 weeks of fully-provided hypocaloric dietary treatment aimed at ~6% weight loss, either with a carbohydrate-reduced high-protein (CRHP, C30E%/P30E%/F40E%) diet or a conventional diabetes (CD, C50E%/P17E%/F33E%) diet. Density profiles of lipoproteins were determined by ultracentrifugation of fluorescently labelled plasma. Magnetic resonance spectroscopy was used to assess IHTG. Results: Body weight decreased by 5.8 kg (~6%) in both groups. Compared with the CD diet, the CRHP diet reduced TRL (mean [95% CI]) by -16 [-30;1]% (p=0.07) and LDL5 by -13 [-22;-3]% (p=0.01), and increased HDL2/HDL3 by 11 [1;22]% (p=0.04). The CRHP diet also decreased IHTG more than the CD diet (-26 [-45;0]%, p=0.05), and changes in IHTG including both groups correlated significantly with changes in TRL and LDL5 (Spearman’s ρ 0.39 and 0.38, p Conclusions: Carbohydrate restriction adds to the positive effect of weight loss in T2D patients by inducing greater improvements in atherogenic lipid profile, maybe facilitated by a reduction in intrahepatic fat.
