the nutritional content and energy density of foods is related to greater control of appetite, satiety and reducing food intake.
METHODS/SUBJECTS:
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.
RESULTS:
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.
CONCLUSIONS:
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.
