Fluid or fuel? The context of consuming a beverage is important for satiety
While energy-containing drinks are said to have a minor effect on satiety (sensation of feeling full), McCrickerd et al. (2014) assessed whether the context in which lower- (LE, 75 kcal) and higher-energy (HE, 272 kcal) beverages are consumed can influence the level of satiety it induces. The two beverages were consumed by 80 participants over two test days in one of four contexts: 20 individuals drank the thin version of the test-drink as a thirst-quencher; another 20 people consumed the beverage as a filling snack; 20 more participants drank the beverage after being given no additional information; and a fourth group of 20 received subtly thicker versions of the beverages without additional information. The amount of food eaten at lunch one hour later depended on the beverage context and energy content (p = 0.03). No significant differences in consumption were found between the higher- and lower- energy drinks in the participants who were not given additional information and in the individuals who perceived the drinks as just thirst-quenchers. But when the beverage was consumed as a filling snack, the subjects ate less at lunch after the HE beverage compared to the LE version. This effect was also observed among those who drank subtly thicker beverages – food consumption was lower after the higher-energy test-drink. These findings provide evidence that beverage intake can affect the impact of its nutrients on appetite regulation and that a beverage’s sensory characteristics can limit its satiating power.
