• Hypothalamic circuits regulate energy intake, adiposity, and obesity phenotypes, with lesion studies and diet-induced obesity in rats and primates revealing neural control of metabolic syndrome across species [11], [15], [16], [18].

• Insulin signaling and diabetes pathology are studied through experimental diabetes models, pancreatic islet pathology, and translational insulin actions, linking endocrine failure to metabolic syndrome [2], [4], [12], [13].

• Nutritional biochemistry and carbohydrate metabolism show how diet composition and carbohydrate handling influence glycogen, appetite, and metabolic regulation in health and disease [1], [17], [18].

• Cardiovascular risk and metabolic syndrome converge via hypertension, atherosclerosis, diet-related lipid disorders, and population-level metabolic phenotype analyses [6], [8], [19], [20].

• Maternal nutrition and nutrient deficiencies affect development and later metabolic outcomes, linking prenatal nutrition to congenital metabolic/vascular phenotypes [7], [9].
