Although there is concern that consumption of high‐energy bars may lead to unhealthy dietary patterns and contribute to obesity risk, few studies have addressed this issue. In this crossover trial, 24‐h energy intakes were assessed in college students ingesting a high‐protein (HP, 280 kcal) or a high‐carbohydrate (HC, 260 kcal) nutrition bar for the breakfast meal and compared to a control day. Fifty‐four students entered the trial, and 39 participants completed all three test days. Daily energy intakes ranged from 1752±99 kcal for the non‐intervention day to 1846±75 and 1891±110 kcal for the days the HP and HC bars were consumed respectively (p=0.591). In the individuals who reported high levels of physically activity (n=11), energy intakes increased significantly compared to the control day for the HC bar day (+45%; p=0.030) and for the HP bar day (+22%; p=0.038). Daily energy intakes did not differ across test days for those with low to moderate physical activity (p=0.595). Macro‐ and micro‐nutrient intakes did differ significantly across test days in the total sample mirroring the nutrient profile of the specific bars. These data suggest that young adults adjust daily caloric intakes appropriately following the ingestion of energy‐dense, novel foods; however, caloric compensation may not occur in those reporting high levels of physical activity.
