In this randomized crossover study, 20 healthy women aged 20-30 years and with a BMI between 20 and 24.9, consumed 3 different snacks in the afternoon separately: yogurt with added whey protein (PSL) biscuits and chocolate. Each time the snack was consumed 3 hours after lunch, which was a standardized menu. The perceived feelings of hunger and fullness were evaluated during the afternoon until the voluntary ad libitum dinner intake. Each snack was tested 3 times.
Whey protein prolonged satiety
The results show that yogurt with PSL leads to a reduction in appetite, which was significantly greater than after the consumption of biscuits and chocolate. In addition, the time between the yogurt snack and eating dinner was 45 minutes longer, compared with the two other snacks, and showed a significant reduction in the caloric intake during that meal.
