“…Case-controlled studies indicate that bariatric surgery patients have lower levels of physical activity than weight-matched nonsurgery controls (21)(22)(23). A number of retrospective cohort studies report a positive association between physical activity and postsurgery weight loss (24)(25)(26)(27)(28). However, these studies are limited by their observational nature, inclusion of only patients who return for follow-up, and subjectively measured physical activity by self-report questionnaires (29).…”

nondiabetic patients following RYGB surgery are typically quite modest compared with the presurgery condition (3). Moreover, there appear to be 2 discrete periods of improvement. The first is immediately after surgery, at which time hepatic, but not peripheral, S I improves in response to acute energy restriction (4-6), while greater, protracted weight loss appears to be more strongly associated with improved peripheral S I (7,8). Even with significant weight loss 1 year following RYBG surgery, peripheral S I is still low compared with that of lean metabolically healthy individuals (3,5,6,9).Exercise is considered a cornerstone for obesity treatment, and while it is not generally viewed to cause substantial body weight reduction (10), it can potently improve peripheral S I and glucose control (11-13) and can reduce the risk of T2D and cardiovascular disease (14,15). There is general consensus that even a single session of moderate intensity exercise can induce an improvement in S I (16). There is also evidence that exercise can BACKGROUND. Roux-en-Y gastric bypass (RYGB) surgery causes profound weight loss and improves insulin sensitivity (S I ) in obese patients. Regular exercise can also improve S I in obese individuals; however, it is unknown whether exercise and RYGB surgery-induced weight loss would additively improve S I and other cardiometabolic factors. METHODS.We conducted a single-blind, prospective, randomized trial with 128 men and women who recently underwent RYGB surgery (within 1-3 months). Participants were randomized to either a 6-month semi-supervised moderate exercise protocol (EX, n = 66) or a health education control (CON; n = 62) intervention. Main outcomes measured included S I and glucose effectiveness (S G ), which were determined from an intravenous glucose tolerance test and minimal modeling. Secondary outcomes measured were cardiorespiratory fitness (VO 2 peak) and body composition. Data were analyzed using an intention-to-treat (ITT) and per-protocol (PP) approach to assess the efficacy of the exercise intervention (>120 min of exercise/week).RESULTS. 119 (93%) participants completed the interventions, 95% for CON and 91% for EX. There was a significant decrease in body weight and fat mass for both groups (P < 0.001 for time effect). S I improved in both groups following the intervention (ITT: CON vs. EX; +1.64 vs. +2.24 min -1 /μU/ml, P = 0.18 for Δ, P < 0.001 for time effect). A PP analysis revealed that exercise produced an additive S I improvement (PP: CON vs. EX; +1.57 vs. +2.69 min

“…É consenso predominante entre investigadores que o critério para avaliação do sucesso no tratamento cirúr-gico da obesidade é a %PEP de pelo menos 50% e a manutenção de peso em longo prazo (13)(14)(15)(16)24). A partir desse critério, as participantes do presente estudo foram divididas e analisadas em três grupos de %PEP: < 50%; 50 ┤75%; ≥ 75%, sendo o primeiro grupo caracterizado como insucesso e os dois outros grupos, como sucesso em relação à perda de peso (13)(14)(15)(16)24).…”

“…Uma perda de peso que se traduz como sucesso cirúrgico deve atingir ao menos 50% do peso excedente no momento da cirurgia (12)(13)(14)(15)(16). Alguns autores estabelecem classificação para sucesso de pós-operatório de acordo com os resultados sobre o índice de massa corporal (IMC), sendo o IMC < 30 kg/m 2 considerado excelente resultado, entre 30 e 35 kg/m 2 , bom resultado e > 35 kg/m 2 , falha ou insucesso (17)(18)(19).…”

Objetivo: Avaliar a evolução e a classificação do peso corporal em relação aos resultados da cirurgia bariátrica em mulheres submetidas ao procedimento cirúrgico há mais de dois anos. Sujeitos e método: Foram avaliadas 141 mulheres submetidas à derivação gástrica em Y de Roux (DGYR) com anel de contenção. As participantes foram divididas de acordo com o tempo de pós-operatório e conforme o percentual da perda do excesso de peso (%PEP): < 50; 50 ┤ 75; e, ≥ 75. Resultados: As mulheres do grupo com %PEP ≤ 50 (15,6%) se mantiveram obesas, enquanto aquelas que apresentaram %PEP ≥ 75 (36,2%) situaram-se entre a eutrofia e pré-obesidade e tiveram menor índice de recuperação tardia de peso em relação aos demais grupos. Conclusão: A evolução de peso após dois ou mais anos da cirurgia mostrou sua esperada redução com variados graus de resposta, apontando a necessidade de monitoramento, investigação e intervenção para obtenção dos resultados esperados.

Subjects and method: A total of 141 women underwent banded Roux-en-Y gastric bypass (RYGB). The participants were divided according to the time elapsed since surgery and the percentage of excess weight lost (%EWL): < 50; 50 ┤ 75; and ≥ 75. Results: The women in the group with %EWL ≤ 50 (15.6%) remained obese, while those with %EWL ≥ 75 (36.2%) ranged from normal to pre-obese and presented lower late weight gain than the women in the other groups. Conclusion: Weight evolution two or more years after surgery showed the expected reductions, with some individuals responding better to surgery than others. This shows that it is necessary to monitor, investigate and intervene to obtain the desired results.

“…Thus, patients may be likely to return to their unhealthy habits after BS 24 . Silver et al 25 showed that only 17.9% of operated patients were engaged in physical activity after two years since BS, while 82.1% of their sample had a moderate level of physical activity. It reinforced the importance of keeping high PAL to prevent weight regain.…”

Sarcopenic Obesity is known as a decrease in the quantity and quality of the skeletal muscle mass and increase in fat mass. It can be measured by the residual appendicular skeletal muscle mass (Ap SMM) based on the difference between actual and predicted values. Even though this condition is more common among sedentary elderlies, it may be present in subjects who underwent Bariatric Surgery (BS). We aimed to evaluate the influence of time after BS and physical activity level (PAL) during leisure time on anthropometric parameters, body composition and sarcopenic obesity markers in women. It is a cross-sectional study involving 42 women divided into two groups according to the time since BS and two groups according to PAL. Anthropometric variables, body composition, and sarcopenic obesity markers were assessed. The variables appendicular skeletal muscle mass, height, and fat mass were used to determine sarcopenic obesity markers. Non-parametric numerical tests were used for group comparison and significance level was set at p<0.05. Considering women with sedentary leisure only, those with longer time after BS had higher current body weight and BMI, waist and hip circumference, fat mass, fat-free mass, Ap SMM (equation, residual, and relative) (p<0.05). Considering women with longer time after BS only, sedentary ones had higher current body weight and BMI, waist circumference, fat mass, fat-free mass (relative only), Ap SMM (equation and relative) (p<0.05). Our data indicate that longer time after BS and sedentary leisure modify anthropometric parameters, body composition and sarcopenic obesity markers in women. KeywordsBariatric Surgery; Body Composition; Sarcopenia; Motor Activity; Obesity. Resumo A Obesidade Sarcopênica é associada à diminuição da quantidade e qualidade da massa muscular esquelética e pelo aumento na massa gorda. Ela pode ser medida pela massa muscular esquelética apendicular (Ap MME) baseada na diferença entre os valores reais e preditos. Mesmo sendo mais comum em idosos sedentários, esta condição pode ser verificada em indivíduos submetidos à Cirurgia Bariátrica (CB). O objetivo do estudo foi avaliar a influência do tempo de CB e nível de actividade física (NAF) durante o lazer em parâmetros antropométri

Weight, Dietary and Physical Activity Behaviors Two Years after Gastric Bypass

Abstract: Postoperative RYGBP patients engage in various weight management behaviors, some of which could offer greater health benefits with follow-up intervention from dietitians and exercise specialists to prevent adverse outcomes such as weight regain and micronutrient deficiencies.
