Energy homeostasis refers to the regulation of energy balance within an organism, ensuring that energy intake matches energy expenditure to maintain a stable body weight and prevent excessive fluctuations in energy levels. This process involves the coordination of various physiological mechanisms, including the control of appetite, metabolism, and energy storage. Dysregulation of energy homeostasis can lead to obesity, metabolic disorders, and other health problems. Researchers in this area study the factors and mechanisms underlying energy balance and develop interventions to promote healthy energy homeostasis.
