Relationship between nutrient intake and body composition one year after bariatric surgery
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 7, Issue 12
Abstract
Reduction in fat mass and fat free mass have been observed with weight loss induced by surgery or dietary interventions. There are concerns that decrease in fat free mass have some negative health consequence. The aim of the current study was to assess the effect of dietary intake after bariatric surgery on fat mass and fat free mass (FFM). In this prospective observational study, 24 female patients with severe obesity (BMI ? 35) or morbid obesity (BMI ? 40) and age between 20-56 years, underwent Ruex- en- Y gastric bypass-RYGB- (11 patients) or laparoscopic sleeve gastrectomy-LSG(13 patients). Anthropometric measurements, body composition, physical activity level, and nutritional intake were assessed before and 1 year after surgery. 24-hours food recall for 3 days was used to assess nutrients intake. Nutritionist IV software was used to analyze the dietary intake. After surgery more than 50% of studied population consumed less than 50% of recommended daily allowance for protein, calcium, iron, phosphorous, magnesium, zinc, vitamin B1, B2, B3, B6, D, and C. There is a significant reduction in energy (p<0.001), protein (p<0.001), potassium (p=0.019), phosphorous (p=0.001), iron (p=0.015), magnesium (p=0.017), zinc (p=0.003), vitamin B1 (p=0.046), B3 (p=0.001), B6 (p=0.034), B9 (p=0.023), and B12 (p=0.043). Patients in RYGB had significantly less intake of vitamin B12 (p= 0.048) and vitamin C (p=0.046) comparing to LSG. In RYGB group, there is a strong relationship between protein intake and the amount of FFM reduction (r= 0.794, p= 0.019). Nutrient inadequacy observed widely after bariatric surgery. Inadequate intake of protein can negatively affect FFM.
