Metabolism is a highly coordinated physiological process that maintains energy balance, supports cellular function and enables adaptation to changing nutritional and environmental conditions. At the center of this regulation is the endocrine system, which integrates signals from multiple organs through hormones that control glucose metabolism, lipid utilization, protein synthesis and energy expenditure. The endocrine regulation of metabolism involves complex communication among organs including the pancreas, thyroid gland, adrenal glands, pituitary gland, liver, adipose tissue, skeletal muscle and gastrointestinal tract. Hormones act as chemical messengers that coordinate physiological responses and maintain metabolic homeostasis. Insulin and glucagon, produced by pancreatic β cells and α-cells respectively, represent fundamental regulators of glucose balance. Insulin promotes glucose uptake, glycogen synthesis and lipid storage, whereas glucagon stimulates glucose production during fasting conditions. Disruption of this balance is a major contributor to metabolic disorders such as diabetes mellitus and insulin resistance. The discovery of additional metabolic hormones has transformed traditional concepts of endocrine regulation. Adipose tissue, once considered merely an energy storage organ, is now recognized as an active endocrine organ that produces adipokines such as leptin, adiponectin, and inflammatory mediators. Leptin regulates appetite and energy expenditure by communicating nutritional status to the hypothalamus, while adiponectin influences insulin sensitivity and lipid metabolism. However, obesity associated alterations in adipose tissue function can disrupt hormonal signaling and contribute to chronic inflammation and metabolic dysfunction. I believe that understanding adipose tissue endocrinology will remain a major focus in developing strategies against obesity and related diseases
