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.

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.

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

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.

The yogurt snack was much less dense in calories per gram than the chocolate or crackers, which might help explain why it kept people fuller longer.
