Adipose tissue (AT), primarily composed of adipocytes, plays a critical role in lipid control, metabolism, and energy storage. Once considered metabolically inert, AT is now recognized as a dynamic endocrine organ that regulates food intake, energy homeostasis, insulin sensitivity, thermoregulation, and immune responses. This review examines the multifaceted role of adiponectin, a predominant adipokine released by AT, in glucose and fatty acid metabolism. We explore the regulatory mechanisms of adiponectin, its physiological effects, and its potential as a therapeutic target for metabolic diseases such as type 2 diabetes, cardiovascular disease, and fatty liver disease. Furthermore, we analyze the impact of various dietary patterns, specific nutrients, and physical activities on adiponectin levels, highlighting strategies to improve metabolic health. Our comprehensive review provides insights into the critical functions of adiponectin and its importance in maintaining systemic metabolic homeostasis. Adiponectin is a protein hormone predominantly released by white adipose tissue, with a crucial function in controlling glucose and fatty acid metabolism. It is the predominant adipokine found in the bloodstream, and its levels in circulation are negatively associated with insulin resistance, a key characteristic of various metabolic diseases. Adiponectin's secretion and function are intricately linked with the physiological roles of white adipose tissue (WAT), brown adipose tissue (BAT), and beige adipocytes, highlighting its significance in maintaining metabolic homeostasis. Adiponectin's secretion is influenced by diet, physical activity, and other lifestyle factors. Low levels of adiponectin are associated with various metabolic disorders, including cardiovascular disease, type 2 diabetes, and nonalcoholic fatty liver disease (NAFLD). Adiponectin has protective effects on the liver, kidneys, skeletal muscle, cardiovascular system, central nervous system, and bones. It enhances insulin sensitivity, reduces inflammation, and improves metabolic health. Adiponectin's role in various diseases, including cardiovascular disease, type 2 diabetes, NAFLD, Alzheimer's disease, and cancer, is well-documented. The concentration of adiponectin in the blood is influenced by numerous factors such as age, gender, body weight, percentage of adipose tissue, and diet. Various dietary patterns and lifestyle interventions have been studied for their impact on adiponectin levels, shedding light on how specific diets and physical activity can improve metabolic outcomes. Energy restriction through low-calorie diets has been shown to effectively increase adiponectin levels, contributing to improved metabolic health. The Mediterranean diet, DASH diet, vegetarian diets, and the ketogenic diet have all been shown to influence adiponectin levels. The synergistic effects of diet and exercise are also important in improving adiponectin levels and metabolic health.
