Article Synopsis
  • The study aimed to determine if muscle strength in the lower limbs after surgery could predict long-term success (36 months) in patients who underwent Roux-en-Y gastric bypass (RYGB).
  • Muscle strength was measured at three points: before surgery, six months after, and 36 months after, with 123 patients initially and 79 at the final measure.
  • Results showed that increasing muscle strength in the lower limbs by at least 4 Nm/kg at six months was linked to about a 76% chance of surgical success by 36 months.

Objective: To analyze whether changes in RMR 6 months after RYGB could be a predictor of weight loss on late follow-up.

Methods: Prospective study of 45 individuals submitted to RYGB in a university tertiary care hospital. Body composition was evaluated by bioelectrical impedance analysis and RMR by indirect calorimetry before (T0), 6 (T1), and 36 months (T2) after surgery.

Background: In the last decades, numerous studies have confirmed the importance of lactate - by-product to the nutrient signal of the intracellular redox state - to regulatory functions in energy metabolism.

Aim: To evaluate changes in blood lactate in patients with severe obesity and its correlation with body composition and metabolic profile.

Methods: Twenty-four people with severe obesity (BMI=40 kg/m2) were evaluated in a prospective case-control study before and six months after Roux-in-Y gastric bypass.

Objective: To analyze the changes in the body composition of morbidly obese patients induced by a very low-calorie diet.

Methods: We evaluated 120 patients selected from a university hospital. Body composition was assessed before and after the diet provided during hospitalization, and changes in weight, body mass index, and neck, waist and hip circumferences were analyzed.

Background: Body mass index (BMI) has some limitations for nutritional diagnosis since it does not represent an accurate measure of body fat and it is unable to identify predominant fat distribution.

Aim: To develop a BMI based on the ratio of trunk mass and height.

Methods: Fifty-seven patients in preoperative evaluation to bariatric surgery were evaluated.

Background: There is an increased interest in understanding how variation in body composition (BC) and energy expenditure is related to successful weight loss after surgery. It has been suggested that low resting metabolic rate (RMR) could be associated with poor weight loss.

Objectives: To determine the relation among changes in BC, RMR, and weight loss after bariatric surgery.

Objective:: The aim of our study was to evaluate associations between maximum voluntary contraction torques of the lower limbs and body composition for subjects with severe obesity.

Methods:: Body composition was evaluated by bioelectrical impedance analysis, and maximum voluntary contraction torques of the lower limbs were measured using an isokinetic dynamometer. One hundred thirty-two patients were enrolled (100 females and 32 males).

Background: Obesity is associated with mobility reduction due to mechanical factors and excessive body fat. The six-minute walk test (6MWT) has been used to assess functional capacity in severe obesity.

Objective: To determine the association of BMI, total and segmental body composition with distance walked (6MWD) during the six-minute walk test (6MWT) according to gender and obesity grade.
