Appetite and satiety. Perceived (a) hunger and (b) fullness assessed throughout the 8 h testing day in 32 healthy women. The time of voluntary dinner request was variable between participants; thus, the data points on the graph, particularly after 2 h post snack, do not contain all 32 volunteer but only those who had not requested dinner yet. Voluntary dinner request is indicated on the graphs as a vertical dotted line; The average time to dinner request for Normal Protein (NP) and Higher Protein (HP) yogurt snacks was 2:43 ± 0:06 and 2:41 ± 0.04 h, respectfully. The post-snack area under the curve (AUC) is shown to the right of the line graphs. The ▲ represents the standardized lunch meal, whereas the Δ represents the NP and HP afternoon yogurt snacks.
