Abstract Metabolic characterization of type 2 diabetes mellitus (T2DM) is crucial for the identification of individuals at risk for developing diabetes and T2DM-related vascular complications as well as for monitoring disease progression. The application of metabolomics to diabetes research may lead to the identification and discovery of diagnostic and prognostic T2DM biomarkers, in addition to elucidating disease pathways. In the present review, we summarize the distinct classes of metabolites that have been proposed as potential biomarkers for progressing stages of T2DM by metabolomic approaches. Several studies have demonstrated that the metabolism of carbohydrates, lipids, and amino acids is considerably altered in prediabetes and continue to vary over the course of T2DM progression. The identification of intermediate metabolites involved in glycolysis, gluconeogenesis, the tricarboxylic acid cycle, lipolysis, and proteolysis have provided evidence of these metabolic dysfunctions. Finally, given the increasing worldwide incidence of T2DM and its related complications, research should focus on the impact of lifestyle factors, particularly diet, at the metabolomic level for better understanding and improved healthcare strategies
