What is the primary purpose of energy balance calculations in nutrition care?

• A. To determine whether intake matches expenditure to maintain, gain, or lose weight.
• B. To determine hydration status
• C. To calculate micronutrient requirements
• D. To measure bone density

Answer: (A)

Energy balance calculations focus on comparing the calories eaten with the calories burned through resting metabolism, activity, and digestion. In nutrition care, the main purpose is to determine whether intake matches expenditure to maintain weight, or to create a deficit for weight loss or a surplus for weight gain. This helps guide treatment plans: if a person wants to maintain weight, intake is aligned with estimated energy needs; for weight loss, intake is reduced or activity increased to create a negative balance; for weight gain, intake is increased to create a positive balance. Hydration status, micronutrient needs, and bone density involve different assessments—fluid and electrolyte balance for hydration, nutrient-specific requirements and labs for micronutrients, and imaging like DEXA for bone density.
