Which statement is true regarding Energy IN and Energy OUT for maintaining current weight?

The concept of energy balance is fundamental to maintaining a stable body weight. For an individual to maintain their current weight, the calories consumed, referred to as Energy IN, must equal the calories expended, known as Energy OUT. This balance ensures that the energy received from food and beverages is used up by the body's metabolic processes and physical activities each day. If Energy IN and Energy OUT are equal, the body does not gain or lose weight, which is essential for weight maintenance.

This concept emphasizes the importance of understanding daily caloric intake and expenditure. Factors such as basal metabolic rate, physical activity, and thermogenesis come into play when calculating Energy OUT, while dietary habits and portion sizes contribute to Energy IN. Hence, consistently balancing these two elements is crucial for maintaining weight.
