After computing an EER using a population-based formula, what is the best evidence-based strategy to refine that estimate for an individual client?

• A. Assume the formula is exact and avoid any follow-up measurements because population equations fully account for genetic and metabolic differences between individuals.
• B. Track the client's actual weight over several weeks while monitoring energy intake; adjust caloric prescription based on observed weight change because individual metabolism varies from formula estimates.
• C. Immediately prescribe 50% more calories than the EER to create an allowance for metabolic variability without monitoring any weight or intake.
• D. Switch to using only RDA values for macronutrients, as EER calculations are irrelevant for healthy individuals and produce unreliable guidance for diet planning.

Answer: (B)
