Energy Balance: Energy In, Energy Out—Yet Not As Simple As It Seems The concept of energy balance seems simple on paper. Balance the calories you consume with the calories you expend. But many factors play a role in energy intake and energy expenditure. Some of these factors are under our control and others are not. In this section, we will define energy balance, look at the different components of energy expenditure, and discuss the factors that influence energy expenditure. We’ll also consider some of the factors that affect energy intake and consider why energy balance is more complex than it seems. ENERGY BALANCE Our body weight is influenced by our energy intake (calories we consume) and our energy output (energy we expend during rest and physical activity). This relationship is defined by the energy balance equation: Energy Balance = energy intake – energy expenditure When an individual is in energy balance, energy intake equals energy expenditure, and weight should remain stable. Positive energy balance occurs when energy intake is greater than energy expenditure, usually resulting in weight gain. 372
