Defects in these systems define a growing class of inborn errors of metabolism, several of which are now clinically recognized and, in some cases, treatable. We summarize recent advances in the discovery and characterization of metabolite damage and repair systems in the tricarboxylic acid cycle, glycolysis, and other pathways, highlighting examples with established or potential links to human disease.

This review synthesizes evidence from objective, rather than verbal report-based, methodologies examining how bariatric surgery and obesity medicines modify human eating behavior. Roux-en-Y gastric bypass and sleeve gastrectomy consistently reduce total energy intake through sustained reductions in meal size and eating rate, without systematic changes in meal initiation or macronutrient selection. In small cohorts where food choices did shift, alterations were associated with greater weight loss, highlighting interindividual variability. GLP-1-based therapy similarly reduces energy intake and improves appetitive behavior through strengthened gut-brain signaling, whereas naltrexone/bupropion primarily targets central reward circuits.
