WEIGHT MANAGEMENT
Body Image Does Not Predict
Caloric Estimation Accuracy
Michael E. Holmstrup, PhD; Amy J. Bidwell, PhD;

This study characterized the accuracy of estimating calories of prepared, healthy meals, with
the specific hypothesis that individuals with greater body dissatisfaction will overestimate calorie
content. Ninety-eight individuals estimated the number of calories in 4 separate healthy meals.
Differences in the bias of caloric estimation were determined in relation to sex, body mass index,
body fat percentage, and body image dissatisfaction. Subjects, regardless of sex, weight status, and
body image, tended to overestimate the number of calories in prepared, healthy meals. Quantifying
portion size makes the task of caloric estimation in prepared meals more difficult and should be
addressed to enhance accuracy. Key words: actual-ideal body fat discrepancy, body image,
calorie estimation

Although food choice is dependent on sev-

knowledge of
caloric content has been shown to influ-

food.

In this vein, adolescents and adults ex-
press major concern for body weight man-
agement when making decisions about food
consumption.

These decisions are often well-
intentioned, if not well-informed. In an effort

The information concerning the
caloric content of home-prepared and small
restaurant meals, however, remains limited.
In addition, mounting evidence of ignorance
toward, underutilization of, and/or confusion
over posted calorie information in large-chain
settings

a focused educational effort should accom-
pany mandated menu labeling

Previous research

has demonstrated
that individuals are relatively inaccurate when
estimating the calorie content of meals, al-
though the underlying cause of this inaccu-
racy is unknown. Given the importance of
food choice and portion size in the devel-
opment of obesity, it is likely that an im-
proved understanding of factors contributing
to caloric estimation accuracy may assist
with obesity-prevention efforts and public
health initiatives by helping individuals im-
prove their food choices.

racy use either written food descriptions or
