[Comparison of the effect of low-glycemic index versus low-fat diet on the body weight and plasma lipid profile in obeses women]

ABSTRACT

The rate of carbohydrate absorption after a meal, as quantified by glycemic index, has an effect on postprandial hormonal and metabolic response. The aim of the present study is to determine the effects of low-glycemic index diet, versus low-fat diet on the body weight, BMI, WHR [waist/hip ratio] and plasma lipid profile of obese patients. A randomized controlled trial compared the effect of two dietary treatments [low glycemic index and low fat] in 46 adults, ages 18 to 55 years old, BMI >27, who proceeded to Motahary Clinic in Shiraz, Iran. Body weight, BMI, WHR [waist/hip ratio], fast and post-prandial Plasma lipid profile [Triacylglycerol, total Cholesterol, LDL-C, HDL-C concentration] level of obese women were measured at the beginning and end of 6 weeks. Changes in Body weight, BMI, WHR [waist/hip ratio] and Plasma lipid profile [Triacylglycerol, total Cholesterol, LDL-C, HDL-C concentration] were significant in both dietary groups. But no significant differences were observed in any parameter measured between two groups, except for the post-prandial HDL-C in which significant difference were observed. From these findings, it can be concluded that the isolated bacterial strain can utilize Organ phosphorus pesticides as a source of carbon and phosphorus. Utilization of these compounds by soil microorganisms is a crucial phenomenon by which these compounds are removed from the environment, thus, preventing environmental pollution. Both diets can equally be effective in decreasing the body weight and Plasma lipid profile
