Higher satiety ratings following yogurt consumption relative to fruit drink or dairy fruit drink.
OBJECTIVE
To compare the satiating power of semisolid and liquid yogurts with fruit beverages and dairy fruit drinks.


METHODS
Thirty-two volunteers (16 men and 16 women), ages 18 to 35 years, consumed a 200-kcal preload stimulus on four separate occasions. A tray lunch was presented 90 minutes after the preload and food consumption was measured.


METHODS
The stimuli were: a semisolid yogurt containing pieces of peach and eaten with a spoon (378 g), the same yogurt in a drinkable homogenized form (378 g), a peach-flavored dairy beverage (400 mL), and a peach juice beverage (400 mL). Participants rated hunger, thirst, satiety, and desire to eat at baseline and at 20-minute intervals after ingestion.


RESULTS
The two yogurts (semisolid and liquid) led to lower hunger and higher fullness ratings as compared with the fruit drink or dairy fruit drink. There was no difference in satiety profiles between the yogurt that was eaten with a spoon and the drinkable version. Energy intakes at lunch were the same across all four conditions (mean+/-standard deviation, 806+/-43 kcal).


CONCLUSIONS
The two yogurts were more satiating than the two beverages. However, lower hunger and higher fullness ratings after yogurt consumption did not lead to energy compensation at the next meal.
