Which scenario describes a positive energy balance?

• A. Energy intake exceeds energy expenditure.
• B. Energy expenditure exceeds intake.
• C. Energy intake equals expenditure.
• D. None.

Answer: (A)

Energy balance is about comparing calories consumed with calories burned. When energy intake exceeds energy expenditure, the extra energy is stored in the body, usually as fat, leading to a positive energy balance. The scenario described shows more calories in than out, so it represents a positive energy balance. If expenditure were greater than intake, that would be a negative energy balance (weight loss). If intake and expenditure are equal, the body is in neutral energy balance (weight stability).
