含能量饮料对饱腹感的影响微弱，这受到其液体特性的限制，也许是因为它们不被视为“食物”。这项研究调查了饮用饮料的环境是否会影响其营养成分的饱腹感。 80 名参与者在两个测试日中，在四种饮料环境之一（组间）中饮用了低能量（LE，75 kcal）和高能量（HE，272 kcal）版本的饮料（在组内秘密操纵）：稀薄版本的测试饮料被用作解渴饮料（n = 20）、填充零食（n = 20），或没有其他信息(n = 20)。第四组在没有额外信息的情况下饮用了稍微浓一点的饮料（n = 20）。 60 分钟后的午餐摄入量取决于饮料背景和能量含量 (p = 0.030)：在没有额外信息的情况下饮用稀饮料的参与者在 LE 和 HE 版本之后吃了相似量的午餐 (LE = 475 kcal，HE = 464 kcal；p = 0.690)，那些相信饮料旨在解渴的参与者也是如此(LE = 442 kcal，HE = 402 kcal；p = 0.213)，尽管在 HE 饮料中额外消耗了 197 kcal。与 LE 版本相比，将饮料作为填充零食饮用后，参与者在午餐时摄入的 HE 饮料较少（LE = 506 kcal，HE = 437 kcal；p = 0.025）。当饮料稍微浓一点时，这种效果也能看到，该组的参与者对饮料的能量含量表现出最大的反应，在 HE 版本之后午餐的摄入量减少了（LE = 552 kcal，HE = 415 kcal；p<0.001）。这些数据表明，对饮用饮料后果的信念可能会影响其营养成分对食欲调节的影响，并进一步证明饮料的感官特征会限制其饱腹感。
Energy-containing beverages have a weak effect on satiety, limited by their fluid characteristics and perhaps because they are not considered ‘food’. This study investigated whether the context of consuming a beverage can influence the satiating power of its nutrients. Eighty participants consumed a lower- (LE, 75 kcal) and higher-energy (HE, 272 kcal) version of a beverage (covertly manipulated within-groups) on two test days, in one of four beverage contexts (between-groups): thin versions of the test-drinks were consumed as a thirst-quenching drink (n = 20), a filling snack (n = 20), or without additional information (n = 20). A fourth group consumed subtly thicker versions of the beverages without additional information (n = 20). Lunch intake 60 minutes later depended on the beverage context and energy content (p = 0.030): participants who consumed the thin beverages without additional information ate a similar amount of lunch after the LE and HE versions (LE = 475 kcal, HE = 464 kcal; p = 0.690) as did those participants who believed the beverages were designed to quench-thirst (LE = 442 kcal, HE = 402 kcal; p = 0.213), despite consuming an additional 197 kcal in the HE beverage. Consuming the beverage as a filling snack led participants to consume less at lunch after the HE beverage compared to the LE version (LE = 506 kcal, HE = 437 kcal; p = 0.025). This effect was also seen when the beverages were subtly thicker, with participants in this group displaying the largest response to the beverage’s energy content, consuming less at lunch after the HE version (LE = 552 kcal, HE = 415 kcal; p<0.001). These data indicate that beliefs about the consequences of consuming a beverage can affect the impact of its nutrients on appetite regulation and provide further evidence that a beverage’s sensory characteristics can limit its satiating power.
