Dr. Kelly asks whether spontaneous caloric and protein intake could have been modified by the ingestion of protein supplements. To avoid significant influence of the supplements on regular food consumption, patients enrolled in the trial were advised to consume the supplements in the evening. Protein intake was evaluated with a food-frequency questionnaire; thus, evaluation relied on the patient's memory. This questionnaire was administered three times during 1 year, the first time within 1 week after surgery. Mean spontaneous protein intake in the protein supplement group was 45.0 ± 2.4 g/d at baseline and 44.0 ± 2.8 g/d at the end of supplement use; in the controls, these values were 51.0 ± 3.0 g/d and 44.0 ± 3.2 g/d. There were no statistically significant differences between the groups and no change over time.
