What does REE stand for in the context of neonatal nutrition?

• A. Resting Energy Expenditure
• B. Real Energy Equivalence
• C. Required Energy Efficiency
• D. Reserve Enzymatic Energy

Answer: (A)

Resting Energy Expenditure is the baseline amount of energy the body uses at rest to support essential physiological functions like breathing, circulation, and cellular maintenance. In neonates, this baseline helps guide nutrition planning—by estimating how much energy is needed just to keep the baby’s organs running, clinicians can then add energy for growth, activity, and the thermic effect of feeding. Indirect calorimetry can measure REE directly, or clinicians can estimate it based on weight and other factors to tailor parenteral or enteral nutrition appropriately. The other terms aren’t standard in neonatal nutrition and don’t describe a recognized component of energy needs.
