Resumen

Introduction: Obesity in recent years has increased its prevalence nationally and internationally. Low glycemic index diets decrease weight and regulate insulin levels in obese patients. Objectives: To determine the effect of a low glycemic index diet in obese women with hyperinsulinemia. Methods: Descriptive, comparative, longitudinal study. The sampling was non-probabilistic of 102 women; 42 patients with a normocaloric diet of 2000 calories and 60 patients with a low glycemic index diet of 1300-1500 calories and was conducted for fourth months. Weight was measured, body mass index (BMI) is calculated and waist circumference (<82 cm), triglycerides (<150 mg/dL), and basal plasma insulin (5-25 uU/ml) were measured. Student-s t-test was performed for paired samples on the variables weight, waist circumference, and BMI to compare the effect of a low glycemic and normocaloric diet before and after treatment. For the variable insulin and triglycerides, the Wilcoxon Signs test is applied. Results: In both diets there was a significant effect of weight loss (Δ-1,20 kg; Δ-5,56 kg), BMI (Δ-0,96 kg/m2; Δ-2,29 kg/m2) and abdominal circumference (Δ-4,88 cm; Δ-5,03 cm)(p<0,001). Triglycerides decreased their values (Δ-5,76 mg/dL; Δ-14 mg/dL) but it was not significant in any of the diets and the low glycemic index diet presented a better insulin reduction (Δ-1,64 uU/ml) (p<0,001). Conclusions: Both diets reduced anthropometric indicators, the low glycemic index diet had a better effect in reducing insulin levels and none of the diets was effective in reducing triglycerides.
