Estimates of energy intake using food records have been reported to underestimate energy requirements by 11-18%. The Dietary Effects on Lipoprotein and Thrombogenic Activity (DELTA) Study (Protocol 1), a multicenter, well-controlled feeding study, provided an opportunity to examine the relationship between the actual energy intake required to maintain weight over 24 wks and self-reported energy intake, assessed using multiple 24 h dietary recalls. Subjects (n=41) provided dietary recalls during feeding periods of the study and during breaks between feeding periods. Recalls were collected for 3 randomly selected days during each period, using a multiple-pass, computer-assisted, interactive telephone interview (Minnesota Nutrition Data Systems (NDS)). Subjects maintained their weight throughout the study. Subjects consistently under-reported energy intake by 6% during both time periods; however the differences between reported and actual intake required to maintain weight were not statistically significant (p<0.05). Because the extent of underreporting of energy intake was similar both during the feeding periods and the free-living situation, we speculate that using a 24-h recall, multiple-pass system with NDS can improve the energy estimation data for a group, compared to other dietary assessment methods.
