Abstract :
Studies have shown that intermittent fasting (JI) has been shown to be effective in combating type ii diabetes mellitus (DM type 2). The objective of this study is to verify the relationship of JI in the management of DM type 2, according to the duration time. It is a systematic review, based on randomized clinical trials. Scientific articles published between the years 2013 to 2018 were investigated in the scientific databases Science Direct, Pubmed and Web of Science. The evaluation of this review occurred through the PRISMA recommendation. After the selection process, 4 articles were included in this review, comparing JI in DM type II with caloric restriction diet (DRC) as a control group, only one showed a significant reduction in HbA1c, and one study showed a significant reduction in fasting blood glucose. In studies that evaluated insulin levels, the reduction of this marker was not significant. The findings of this review do not provide plausible evidence of the benefits of JI in the improvement of the DM type 2 indicators in humans when compared to a DRC in the different intervention times. Key words: Fasting. Diabetes Mellitus. Chronic disease. Nutrition therapy. Estudos evidenciam que o jejum intermitente (JI) tem se mostrado eficiente no combate a diabetes mellitus tipo 2 (DM tipo 2). O objetivo deste estudo e verificar a relacao do JI no manejo do DM tipo 2, conforme o tempo de duracao. Trata-se de uma revisao sistematica, baseada em ensaios clinicos randomizados. Foram investigados artigos cientificos publicados entre os anos de 2013 a 2018 nas bases de dados cientificas ScienceDirect, PubMed e Web of Science. A avaliacao dessa revisao ocorreu por meio da recomendacao PRISMA. Apos o processo de selecao, 4 artigos foram incluidos nesta revisao, comparando o JI no DM tipo 2 com dieta de restricao calorica (DRC) como grupo controle, apenas um revelou reducao significativa na HbA1c, e um estudo mostrou reducao significativa da glicemia em jejum. Nos estudos que avaliaram os niveis de insulina, a reducao desse marcador nao foi significativa. Os achados dessa revisao nao fornecem evidencias plausiveis dos beneficios do jejum intermitente na melhora dos indicadores do DM tipo 2 em humanos, quando comparado com dieta de restricao calorica nos diferentes tempos de intervencao.
