Abstract Humans with the metabolic syndrome and type 2 diabetes have an altered gut microbiome. Emerging evidence indicates that it is not only the microorganisms and their structural components, but also their metabolites that influences the host and contributes to the development of the metabolic syndrome and type 2 diabetes. Here, we discuss some of the mechanisms underlying how microbial metabolites are recognised by the host or are further processed endogenously in the context of type 2 diabetes. We discuss the possibility that gut-derived microbial metabolites fuel the development of the metabolic syndrome and type 2 diabetes. Keywords Intestinal barrier . Metabolites . Microbiome . Review .

The gut microbiome in humans can be considered as an organ, which has functions critical for human metabolism, digestion, maintenance of gut barrier function and immunomodulation. Moreover, the gut microbiome has been linked to many diseases not classically associated with microbes, such as metabolic diseases, rheumatoid arthritis and psychiatric disorders. A skyrocketing number of publications implicate the gut microbiome in the development of metabolic diseases including obesity and type 2 diabetes. Although the majority of publications on human disease development are associative and, as yet, do not provide much mechanistic insight, the field is rapidly moving towards translational studies combining animal models with human intervention. This movement is
