2 Fig. 1 Comparing responses to weight loss interventions through extensive phenotyping and data integration. There are phenotypic and behavioral traits that differentiate responders vs. non-responders to weight loss interventions. These differences can be compared 1) at baseline, between responders (status Y) and non-responders (status X) for prediction (yellow profile vs. orange profile), and 2) before vs. after the intervention (yellow profile vs. blue profile) to study mechanisms that may be involved in a good response to the intervention. Environment may refer to diet, exercise, behavior, and other environmental exposures. Omics may refer to genomics, epigenomics, transcriptomics, proteomics and metabolomics in different tissues.

3 Fig. 2 Dietary intervention such as prebiotic supplementation as well as gastric surgery impact gut microbiota and host metabolism and thereby represent interesting approaches for the treatment of obesity and metabolic disorders. Obesity is associated with alterations in metabolism and energy homeostasis. Gastric bypass surgery is associated with changes in gut microbiota composition and metabolic functions and represents one of the more effective approaches to treat obesity and metabolic disorders. Dietary interventions targeting the gut microbiota, such as prebiotics, induce changes in gut microbiota composition that are associated with modification of the secretion of gut enteroendocrine hormones as well as with a reduction in metabolic inflammation, and glucose, lipid and energy homeostasis dysfunctions.

4 Fig. 3 Modelisation of the gut ecosystem as a first step for personalized nutrition. Individuals with low and high gut microbial richness differ in certain clinical parameters, dietary intake and metabolite profile. The CASINO toolbox predicts, at the individual level, differences in metabolite production by gut bacteria and proposes changes in dietary intake for individuals with low gene richness to improve their gut microbiome metabolism.
