A obesidade está intimamente ligada ao estado inflamatório, sendo considerada uma patologia metabólica complexa. Dietas hipercalóricas alteram a composição da microbiota intestinal, sendo a mudança da proporção de bactérias dos filos Bacteroidetes e Firmicutes uma das consequências mais conhecidas.  Essa mudança determina a produção de metabólitos específicos do sistema imune, induzindo estado inflamatório responsável pelo agravamento de uma série de doenças. A dieta hipercalórica representa um fator de risco para a obesidade e para o diabetes mellitus, doenças interligadas pelo conceito de lipotoxicidade, e o estado inflamatório também contribui para o aparecimento e para a progressão de doenças cardiovasculares. Com esse artigo, objetivamos estudar a obesidade pela perspectiva imunológica e microbiológica, abordando as consequências de dietas hipercalóricas sobre o estado inflamatório e a sobre a microbiota. Ademais, associar a mudança no microbioma a doenças prevalentes como o diabetes mellitus e as doenças cardiovasculares, apontando abordagens terapêuticas potenciais.
