A study from the University of Washington in Seattle tested hunger, fullness, and calories eaten at the next meal on 16 men and 16 women who had a 200-calorie snack. The snack was either:
- Semisolid yogurt containing pieces of peach and eaten with a spoon
- The same yogurt in drinkable form
- A peach-flavored dairy beverage
- Peach juice
Although those who had the yogurt snacks did not eat fewer calories at the next meal, both types of yogurt resulted in lower hunger ratings and higher fullness ratings than either of the other snacks.
