What does energy balance refer to?

Energy balance refers to the state at which caloric intake matches caloric expenditure. This balance is crucial for maintaining body weight. When energy intake from the food and beverages consumed is equal to the energy expended through metabolic processes and physical activity, the body remains in equilibrium, and weight stays constant.

This concept of energy balance is foundational in understanding weight management because it highlights the importance of both diet and exercise in maintaining or changing body weight. When the energy consumed is equal to the energy burned, the body's weight is stable. If more calories are consumed than are used, a positive energy balance results, leading to weight gain. Conversely, a negative energy balance, where calorie expenditure exceeds intake, can lead to weight loss.

Understanding this concept allows individuals to make informed choices about their dietary habits and activity levels to achieve their weight management goals.
