Métodos: Participaram da pesquisa 20 mulheres (IMC: 40 e 50 kg/m2; idade de 20 a 45 anos). As variáveis do estudo foram coletada nos momentos pré, 6 e 12 meses pós-cirurgia. O GET, massa livre de gordura (MLG) e massa gorda (MG) foram mensurados pela técnica da água duplamente marcada. O nível de atividade física (NAF) e o gasto de energia em atividade física (GEAF) foram obtidos por meio acelerômetro. O consumo energético foi obtido por três registros alimentares. Foram selecionadas as seguintes equações preditivas de gasto energético: Harris e Benedict (1819), World Health Organization (WHO-1985), Mifflin-St Jeor et al (1990), De Lorenzo et al (2001), por Müller et al (2004), Henry (Oxford - 2005), Dietary Reference Intake (DRI - 2005) e Lazzer et al (2007). Resultados: A perda ponderal (6 meses: -31 ± 4kg; 12 meses: -38 ± 6kg) teve contribuição de 17% e 16% da perda de MLG nos momentos 6 e 12 meses, respectivamente. O valor da razão MLG/MG passou de 0,93 ± 0,12kg do momento pré-cirurgia para 1,54 ± 0,4kg e 1,98 ± 0,6kg nos momentos 6 e 12 meses pós-operatórios (p<0,05). O GET reduziu 20% (-612 ± 317 kcal.dia-1) aos 6 meses -10% (-447 ± 516 kcal.dia-1) aos 12 meses de cirurgia, em relação ao valor pré-cirúrgico (p<0.05). Quando corrig...

Methods: Twenty women (BMI: 40 and 50 kg/m 2 ; aged 20 to 45 years) participated in the study. The study variables were collected at pre, 6 and 12 months postoperatively. TEE, fat-free mass (FFM) and fat mass (FM) were measured by the doubly labeled water technique. The physical activity levels (PAL) and energy expenditure in physical activity (EEPA) were obtained through accelerometer. Energy intake (EI) was calculated using 3 days of dietary diaries. The following predictive energy expenditure equations were selected: Harris and Benedict (1819), World Health Organization (WHO-1985), Mifflin-St Jeor et al (1990), De Lorenzo et al (2001), Müller et al (2004), Henry (Oxford - 2005), Dietary Reference Intake (DRI - 2005), and Lazzer et al (2007). Results: The weight loss (6 months: -31 ± 4kg, 12 months: -38 ± 6kg) had a contribution of 17% and 16% of FFM loss at moments 6 and 12 months, respectively. The FFM/FM ratio increased from 0.93 ± 0.12kg from preoperative time to 1.54 ± 0.4kg and 1.98 ± 0.6kg at moments 6 and 12 postoperative months (p<0.05). The TEE reduced at 6 months 20% (-612 ± 317 kcal.dia-1 ) and -10% (-447 ± 516 kcal.dia-1 ) at 12months after surgery, in relation to the preoperative value (p <0.05). When corrected for lean mass, TEE/FFM showed no significant difference at the end of the first year. From the TEE data measured in relation to the predicted values by an equation developed for these patients, the adaptive thermogenesis was evidenced at 6 months...
