Efeito da dieta rica em proteínas na composição corporal de pacientes obesos no centro especializado do Distrito Federal

Abstract

Objective: to evaluate the effect of a high-protein diet on the body composition of obese people followed up at the Specialized Center for Diabetes, Obesity and Hypertension of the Federal District (CEDOH). Methods: a nonrandomized clinical trial study with 41 patients who started obesity treatment at CEDOH. Descriptive statistics and the Mann-Whitney test and the Spearman correlation test were performed. They were evaluated using bioimpedance (BIA) at the beginning and end of the study. Half of the group received protein supplementation of 30 g per day for 30 days. Results: most patients were women, with a mean age of 44 years, weight of 111 kg and Body Mass Index (BMI) of 40.4 kg/m2, with a low percentage of muscle mass (MM) (29.46 % ± 3.24) and high percentage of fat mass (FM) (47.54 ± 5.24), hypertensive, physically active, with sarcopenic obesity, according to the criteria of Kim et al., 2009. The intervention group had an average reduction of 0.55 kg of weight, increase of 0.16% of MM and reduction of 0.06% of MG compared to the control. Conclusions:a high-protein diet with the use of a protein supplement can be suggested to optimize results in the treatment of obese patients, since there was an improvement in the body composition of those who used the supplementation in relation to the control.
