Abstract

BACKGROUND:

Breakfast omission is known to be associated with lower 24-h energy intake. However, little is known about downstream eating behaviors subsequent to skipping breakfast in free-living individuals.

OBJECTIVE:

We replicated the traditional crossover design of nutrition studies in a naturalistic setting to compare within-person differences in self-reported eating behaviors, energy intake, and other dietary characteristics of individuals on a day that included breakfast with a day that omitted breakfast.

DESIGN:

We used cross-sectional dietary data for 2132 adult respondents who reported breakfast in only one of 2 dietary recalls in the NHANES 2005-2010. Dietary outcomes examined included meal- and snack-eating behaviors, clock time of eating episodes, and intakes of energy, macronutrients, and food groups. Regression methods accounted for replicate diet measurements, covariates, and survey-design characteristics.

RESULTS:

The breakfast meal provided a mean of 508 kcal in men and 374 kcal in women, but differences in 24-h energy intakes between the breakfast and no-breakfast day were 247 and 187 kcal, respectively. Energy intakes at the lunch meal were higher on the no-breakfast day (202 kcal in men and 121 kcal in women), and the reported time of lunch was ∼35 min earlier. The energy contribution of dinner or its reported time did not differ. A higher number of energy-adjusted servings of fruit and whole grains were reported on the breakfast day, but the energy and macronutrient density of reported foods were not different.

CONCLUSIONS:

In free-living American adults, the eating time for lunch was earlier, and the lunch meal provided more energy on the no-breakfast day than on the breakfast day. Although the quality of dietary selections reflected in the energy and macronutrient density of a day's intake did not differ between the breakfast and the no-breakfast day, breakfast skippers may need encouragement to consume fruit and whole grains at other eating episodes.
