Estimates of food quantity and calories: errors in self-report among obese patients.

We report three studies that examine the accuracy and usefulness of food records among dieting obese patients. In study 1 errors in quantity and calorie estimates for 10 common foods averaged 63.9% (quantity) and 53.4% (calories). The results of study 2 indicate that only 53% of entries in daily food records were specified enough to permit objective estimates of the calories consumed. In study 3, blind raters could not predict weight loss based on subjects' self-recorded behavior changes. Collectively, these results question the utility of food records for estimating energy intake or predicting weight loss.

Teaching home parenteral nutrition to patients with limited compliance skills.

Information gathered from psychological and behavioral assessment procedures was used to select a teaching approach for two home parenteral nutrition patients with limited abilities to learn--and therefore to comply with--their regimens. A "behavior shaping" procedure, involving the simplification of complex home parenteral nutrition tasks, resulted in significantly improved performance by both patients. Results suggest that these procedures may be applied to other home parenteral nutrition patients, including those without apparent skill deficits.
