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

Assume the formula is exact and avoid any follow-up measurements because population equations fully account for genetic and metabolic differences between individuals.

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.

Immediately prescribe 50% more calories than the EER to create an allowance for metabolic variability without monitoring any weight or intake.

Switch to using only RDA values for macronutrients, as EER calculations are irrelevant for healthy individuals and produce unreliable guidance for diet planning.
