Resumo: | ObjectiveThe objective of this study was to describe changes in the resting energy expenditure, substrate oxidation rate, and body composition in morbidly obese women subjected to short-term caloric restriction. MethodsThis was a prospective study that included ten obese women with body mass index greater than 40 kg/m2 and aged between 20-50 years. The participants were hospitalized for eight days and received a controlled conventional low-calorie diet, 1200 kcal/day, for seven days. Body weight, body mass index, abdominal circumference, body composition, resting energy expenditure, and substrate oxidation rate were evaluated at the beginning and at the end of the study. ResultsA significant reduction in body weight (p=0.005), body mass index (p=0.005), abdominal circumference (p=0.005), fat mass (p=0.005) and fat-free mass (p=0.008) was observed at the end of the study. There was an average reduction in resting energy expenditure of approximately 124 kcal/day (5%). Substrate oxidation rate did not show statistically significant changes. There was a positive correlation only between body weight reduction and fat-free mass reduction (r=0.753; p=0.012). ConclusionThere was an adaptive response of the resting energy expenditure with short-term energy restriction in morbidly obese women with a 5% reduction in resting energy expenditure and a positive correlation between weight loss and the fat-free mass, which indicates the influence of fat-free mass on the decrease in resting energy expenditure. Therefore, short-term caloric restriction in morbidly obese women led to a decrease in resting energy expenditure and fat-free mass, which suggests a rapid adaptation of energy expenditure. |

MétodosEste foi um estudo prospectivo com dez mulheres obesas com índice de massa corporal maior que 40 kg/m2 e idade entre 20-50 anos. As participantes foram hospitalizadas por sete dias consecutivos e receberam uma dieta hipocalórica convencional controlada de 1200 kcal/dia. Peso corporal, índice de massa corporal, circunferência abdominal, composição corporal, gasto energético de repouso e taxa de oxidação de substratos foram avaliados no início e no final do estudo. ResultadosReduções significativas no peso corporal (p=0,005), índice de massa corporal (p=0,005), circunferência abdominal (p=0,005), massa gorda (p=0,005) e massa livre de gordura (p=0,008) foram observadas no final do estudo. O gasto energético de repouso mostrou redução média de aproximadamente 124 kcal/dia (5%). A taxa de oxidação de substratos não apresentou mudanças estatisticamente significativas. Houve correlação importante apenas entre a redução do peso corporal e a redução da massa livre de gordura (r=0,753, p=0,012). ConclusãoHouve uma resposta adaptativa do gasto energético de repouso com restrição energética em curto prazo em mulheres obesas mórbidas, apresentando redução média de 5% do gasto energético de repouso e correlação entre a perda de peso e a massa livre de gordura, o que indica a influência da mesma na diminuição do gasto energético de repouso. Portanto, a restrição calórica de curto prazo em mulheres obesas mórbidas leva à diminuição no gasto energético de repouso e na massa livre de gordura, sugerindo uma rápida adaptação do gasto energético.Núcleo de Editoração – PUC-Campinas2023-04-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/8245Brazilian Journal of Nutrition; Vol. 28 No. 5 (2015): Revista de NutriçãoRevista de Nutrição; Vol. 28 Núm. 5 (2015): Revista de NutriçãoRevista de Nutrição; v. 28 n. 5 (2015): Revista de Nutrição1678-9865reponame:Revista de Nutriçãoinstname:Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)instacron:PUC_CAMPenghttps://periodicos.puc-campinas.edu.br/nutricao/article/view/8245/5770Copyright (c) 2023 Andresa Toledo TRIFFONI-MELO, Vivian Marques Miguel SUEN, Cristina Maria Mendes RESENDE, Camila Bitu Moreno BRAGA, Rosa Wanda DIEZ-GARCIAhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Toledo TRIFFONI-MELO, Andresa Marques Miguel SUEN, Vivian Mendes RESENDE, Cristina MariaBitu Moreno BRAGA, Camila Wanda DIEZ-GARCIA, Rosa2023-04-05T15:22:58Zoai:ojs.periodicos.puc-campinas.edu.br:article/8245Revistahttp://www.scielo.br/rnPRIhttps://periodicos.puc-campinas.edu.br/nutricao/oai||sbi.submissionrn@puc-campinas.edu.br1678-98651415-5273opendoar:2023-04-05T15:22:58Revista de Nutrição - Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)false |
