What error results from failing to adjust final weight manually?
Answer
An overestimation of nutrient density per serving.
When calculating the nutrition of a composite food item manually, if one fails to adjust the total nutrient sum by dividing it by the accurate final weight of the cooked product, an overestimation of nutrient density per serving occurs. This mistake is common when water evaporates during processes like roasting meat or baking bread. Since the total absolute amount of nutrients (like protein or fat) remains the same, but the total weight decreases due to water loss, failing to use the lower final weight as the denominator results in an inflated nutrient value when calculating density or per-serving amounts.
