Despite its benefits, including improved glycemic control and weight loss, the common metabolic changes induced by liraglutide and correlations between those in rodents and humans remain unknown. Here, we used advanced machine learning techniques to analyze the plasma metabolomic data in diet-induced obese (DIO) mice and patients with T2DM treated with liraglutide. Among the machine learning models, Support Vector Machine was the most suitable for DIO mice, and Gradient Boosting was the most suitable for patients with T2DM. Through the cross-evaluation of machine learning models, we found that liraglutide promotes metabolic shifts and interspecies correlations in these shifts between DIO mice and patients with T2DM. Our comparative analysis helped identify metabolic correlations influenced by liraglutide between humans and rodents and may guide future therapeutic strategies for T2DM and obesity.  \nKeywords: type 2 diabetes mellitus; obesity; liraglutide; metabolomics; metabolic profiling; machine learning  \n1. Introduction  \nType 2 diabetes mellitus (T2DM) and obesity are major global health issues that have significant complications and increase the risk of morbidity and mortality [1,2] . Over the past 20 years, therapies based on incretin hormones, particularly glucagon-like peptide-1 receptor agonists (GLP-1 RAs), have become the preferred treatment for T2DM and obesity due to their efficacy and safety in numerous clinical trials [2–4] . Among the most widely adopted GLP-1 RAs, liraglutide substantially improves glycemic control and promotes weight loss [5–10] . Recent advancements in omics technologies, including proteomics and metabolomics, have demonstrated that liraglutide treatment significantly changes protein expression and metabolite levels across various biological samples in patients with T2DM and obesity and in mouse models [11–17] . The identified proteins and metabolites provide insights into liraglutide’s multifaceted mechanisms of action, which improve glycemic control and lipid profiles, reduce inflammation, and potentially offer cardiovascular and renal benefits [11–17] .  \nMetabolomics encompasses the analysis of a vast array of metabolites present in biological samples using sophisticated analytical techniques. The ongoing challenges of such analysis include obtaining metabolic snapshots and surrogate diagnostics, identifying biomarkers, elucidating the mechanisms driving metabolic disorders, and evaluating drug efficacy and therapeutic outcomes [18, 19] .
