This experimental pilot study compared the composition of a snack in a multidimensional approach to satiety in 18 healthy young men of normal weight.
Volunteers were asked to eat four meals a day in the laboratory, including a snack consisting of either liquid yogurt or a chocolate bar, identical in weight (366 g) and calories (285 kcal). The perception of hunger, appetite, desire to eat and stomach fullness were measured at regular intervals of 20 minutes. The time until the next meal and its caloric intake were also assessed.
The results show a higher perception of satiety after 60 minutes with yogurt, but no significant difference between the two foodstuffs in the time before taking the next meal or the calories it contained.
