Women who eat a high-protein yogurt snack in the afternoon wait about half an hour longer before feeling hungry enough to eat dinner than those who eat a chocolate snack.

The yogurt snack made women wait about 20 minutes longer before eating dinner than the crackers did, but this difference was close to being statistically significant.

Even though the yogurt had more protein, it didn’t make women feel significantly fuller than the crackers at the 90-minute mark.

Other studies have found mixed results when testing protein snacks, meaning the effect isn’t always the same—it depends on what kind of snack and who’s eating it.

Even though a yogurt snack and a cracker snack had the same calories, women ate less at dinner after the yogurt—yet they didn’t feel less hungry than after the crackers.

Women ate about 100 fewer calories at dinner after eating yogurt than after chocolate, but this difference was just shy of being statistically significant.
