Abstract
We have evaluated the effect of regular consumption of orange juice in body composition and biochemical variables. The subjects of this study were obese men and women (36.3±0.8 y) who were submitted to an energy-restricted diet for 12 weeks. They had normal blood serum levels of cholesterol, triglycerides and glucose, and were randomly divided into 2 parallel groups. Group 1 (n=39) had an energy-restricted diet (-500 kcal/d) and Group 2 (n=39) had the same energy-restricted diet supplemented with orange juice (500 mL/d). The assessment of body composition (weight, BMI, fat mass, waist and hip circumference and ratio) were performed at week 0 and every 2 weeks until the end of the 12-week trial period. Evaluations of biochemical parameters (total cholesterol, LDL-C, HDL-C, triglycerides, glucose, insulin, HOMA-IR and CRPu) were performed 0, 4, 8 and 12 weeks. After the treatment, individuals undergoing only energy-restricted diet had a reduction in body composition parameters as well as biochemical parameters. In addition, individuals who also regularly consumed orange juice showed lower levels of blood serum cholesterol (-20%), LDL-C (-19%), CRPu (-49 %), insulin (-27%) and HOMA-IR (-33%). In conclusion, orange juice enhanced the effects of energy-restricted diet improving both lipid and glucose metabolism, showing that it is suitable for weight loss purposes as well as for the improvement of the biochemical profile of obese individuals.
