Background and aims: Although some studies have examined the efficacy of dietary glycemic index on blood lipids among adults, little information reported for adolescents in this regard. This study was conducted to determine the effects of low glycemic index (LGI) diet compared to healthy nutritional recommendation (HNR) based diet on lipid and apolipoproteins profiles among female adolescents with overweight and obesity. Methods: In this roudomized clinical trial study, fifty healthy overweight/obese adolescent girls all with the same pubertal status were randomly assigned to either LGI or HNR diet based groups. Participants in both groups consumed diets with equal macronutrient composition (53%-56% corbohydrale, 16%-18% proteinT 27%-30. fat). Biochemical variables included total cholesterol, low density lipoprotein, high density lipoprotein, triglyceride, apolipoprotein B and apolipoprotein A and lipoprotein (a) were measured once at baseline and another time at the end of the study. Baseline and endpoint values of each group were compared by paired t -test. The between groups variations were compared by independent t test in SPSS. Results: Glycemic index in LGI group was lover than 50 (42.67 ± 0.67). Mean of body mass index in LGi group was 27.97 ± 0.55 mm/ and it was 28.82 ± 1.01 in WNR group. Mean of the age in NHR group was significantly higher comopare with LGI group. (P=0.031, 13.18 ± 0.21 to 13.98 ± 0.27). Biochemical variables levels were not significantly different in baseline and endpoint (P<0.05). Percentoge of blood lipid index changes in LGL of HNR showed no significantly difference in: TG changes (respectively 27.90 ± 17.20, 6.15± 10.53, P=0.274, TC (5.58± 4.49, -0.65 ± 3.63, P= 0.283), HDL (1.20 ±4.05, -1.77 ±3.07, P=0.556), LDl (4.35± 4.52, -2.24 ±3.32, P=0.225), Apo A (-0.18 ± 5.73, -9.37± 5.19, P=0.242), Apo B (10.24 ±7.22, 6.73 ± 7.40, P=0.738), Lpa (57.71± 40.13, 97.18 ± 47.24, P=0.676) between two groups. Conclusion: LGI diet had no more beneficial effect on blood lipid than HNR based diet.
