Implications of consumption of protein and practice of physical activity in lean body mass of women exposed to gastric bypass
Abstract
Objective: To evaluate the implications of protein intake and physical activity on lean body mass in women undergoing gastric bypassafter 1 year. Materials and Methods: It was included 30 women in postoperative gastric bypass period ≥ 1 year. Anthropometric measurements and body composition by bioelectrical impedance analysis were performed; assessment of protein intake by FFQ (Food Frequency Questionnaire) and supplementation; and physical activity, and the parameters were compared with the recommendations of the American Association of Clinical Endocrinologists. Results: The average height excess loss found was 68.8±19.4%. As for protein intake, it was noted that only through diet, this intake was below the recommendations that 60g/day, and appropriate values were achieved when added to supplementation (73.9±23.9g/day). The average physical activity was 135±161.4 minutes weekly. When combined, it was noted that adequate protein intake positively influenced the percentage of lean body mass (69.1±5.1% vs65.7±6.1%) and %EWL (69.7±15.7% vs67.2±25.4%) as well as the proper practice of physical activity (69.0± 4.8% vs66.9±6.2%). Conclusion: Adequate protein intake and regular physical activity appear to be beneficial in the preservation of lean body mass after bariatric individuals.
