Energy balance refers to the relationship between the energy consumed through food and beverages and the energy expended through physical activities and bodily functions. When the energy intake equals energy expenditure, the body is in a state of balance, which helps maintain weight. If energy intake exceeds expenditure, the body stores the excess energy as fat, leading to weight gain. Conversely, if energy expenditure surpasses intake, the body uses stored fat for energy, resulting in weight loss. Achieving a healthy energy balance is essential for overall well-being and can be influenced by factors such as diet, exercise, and metabolism.
