Abstract(s)
Introdução: Na atualidade, os indivíduos estão cada vez mais sensibilizados com a sua saúde e o seu bem-estar, o que leva à adoção de uma grande variedade de estilos de vida considerados saudáveis. O jejum intermitente (JI) tem vindo a ganhar uma maior visibilidade devido aos benefícios da sua prática associados a uma melhoria contínua do organismo.
Métodos: Foi efetuada uma revisão da literatura sobre os benefícios do JI na saúde, direcionada para os benefícios no sistema cardiovascular, diabetes, sistema nervoso central (SNC) e cancro. A pesquisa foi realizada na base de dados Pubmed, Scielo e Medline, tendo em conta os últimos dez anos e fundamentalmente ensaios clínicos.
Resultados: Os ensaios realizados em humanos mostram que a prática do JI apresenta melhorias na saúde: diminuição de peso corporal, melhora da pressão arterial, diminuição do índice de massa corporal (IMC), diminuição de crises epiléticas e aumento dos eritrócitos durante ciclos de tratamento de quimioterapia. Os participantes dos estudos não demonstraram efeitos secundários significativos.
Conclusão: O JI poderá melhorar a qualidade de vida, beneficiando quem dele pratica. Existem vários tipos de JI mas ainda não se encontra claro qual o tipo que parece ser mais adequado e qual a frequência em que deve ser praticado, uma vez que é difícil conseguir a comparação de resultados obtidos pois cada ensaio é realizado de forma diferente e com um número de participantes reduzido. Esta situação gera dificuldades na elaboração de normas e recomendações para o estabelecimento da prática JI como uma medida de saúde.
Introduction: Nowadays, individuals are increasingly aware of their health and well-being, which leads to the adoption for a wide variety of healthy lifestyles. Intermittent fasting (IF) has gained greater visibility due to the benefits of its practice associated with a continuous improvement of the body. Methods: A literature review was performed on the health benefits of IF, focusing on the benefits on the cardiovascular system, diabetes, central nervous system (CNS) and cancer. The research was carried out in the Pubmed, Scielo and Medline databases, taking into consideration the last ten years and essentially clinical trials. Results: Trials performed on humans show that the practice of IF has several health improvements: decreased body weight, improved blood pressure, decreased body mass index (BMI), decreased epileptic seizures and increased erythrocytes during cycles of chemotherapy treatment. Study participants did not demonstrate significant side effects. Conclusion: IF can improve the quality of life, benefiting those who practice it. There are several types of IF but it is still not clear which type seems to be the most suitable and how often it should be practiced, since it is difficult to compare the results obtained because each test is performed differently and with a reduced number of participants. This situation creates difficulties in the development of norms and recommendations for the establishment of the IF practice as a measure of health.
