the nutritional content and energy density of foods is related to greater control of appetite, satiety and reducing food intake. the randomized crossover study included 20 healthy women, aged 20 and 30 years with a BMI of 20 to 24.9 kg/m2 and who completed that included 3 day trial comparing 8 hours 130 kcal snacks consumed afternoon: yoghurt with added whey protein (PSL), biscuits and chocolate. Participants consumed a standardized menu; snack was consumed 3 hours after lunch. Perceived hunger and fullness were evaluated during the afternoon until dinner voluntary intake ad libitum. They repeat the same snack 3 times. consumption of yogurt with PSL led to a further reduction of appetite in the afternoon in front of the snack of chocolate and biscuits (p < 0.001). No differences of appetite in the afternoon between chocolate vs cookies but significant difference between yogurt with PSL and other treatments (p < 0.001) were detected. At snack, yogurt there was a significant reduction in caloric intake compared to other snacks (p < 0.001) and a later request for dinner with about 45 minutes apart. snacks with less energy density and rich in protein (yogurt with PSL) improve the control of appetite, satiety and reduces food intake in healthy women later.
