Objective: The aim of this study is to provide a comprehensive overview of the relationship between obesity and type 2 diabetes (T2D) and to identify the key environmental, behavioral, and biological factors involved in their development. A review of current scientific literature concerning the epidemiology, pathophysiology, and risk factors of both conditions was conducted, with particular emphasis on the roles of diet, physical activity, gut microbiota, and socio-economic determinants.
Analysis: The analysis demonstrated that obesity, particularly visceral adiposity, constitutes the primary risk factor for type 2 diabetes. The central mechanism linking these conditions is insulin resistance, which is exacerbated by chronic low-grade inflammation and adipose tissue dysfunction. Significant importance is attributed to unfavorable dietary patterns, including the high consumption of ultra-processed foods and high-glycemic-load diets, both of which promote metabolic disturbances. Furthermore, the role of gut microbiota in metabolic regulation was highlighted, alongside the impact of physical activity – specifically mechanisms involving GLUT4 translocation and Non-Exercise Activity Thermogenesis (NEAT) on improving glucose homeostasis. Additionally, environmental and socio-economic factors, such as urbanization, food accessibility, and educational attainment, significantly modulate disease risk.
Conclusions: The findings indicate that obesity and type 2 diabetes share a common, multifactorial etiology. Consequently, effective prevention and management require an integrated approach encompassing lifestyle modifications, systemic interventions, and the utilization of modern health-supporting technologies.
