After eating a protein-rich yogurt snack, women ate about 100 fewer calories at dinner than after eating a chocolate snack, meaning they didn’t overeat later to make up for the snack.

Scientific Claim

In healthy women aged 27 ± 2 years with normal BMI (23.4 ± 0.7 kg/m²), consuming a 160-kcal high-protein yogurt snack results in approximately 100 fewer kilocalories consumed at a subsequent ad libitum dinner compared to a 160-kcal high-fat chocolate snack (p < 0.05), suggesting reduced compensatory eating.

Original Statement

“The yogurt snack led to approximately 100 fewer kcals consumed at dinner vs. the chocolate (p < 0.05)”

Randomized Controlled Trial

Human

2014 Sep 29

Women who ate a high-protein yogurt snack in the afternoon ate about 100 fewer calories at dinner than when they ate a chocolate snack, even though both snacks had the same calories — suggesting the yogurt made them feel fuller longer.

Similar Assertions

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

94%

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.

89%

Even though the yogurt snack wasn’t as tasty as the chocolate or crackers, it still made women less hungry and made them eat less later.

87%

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.

87%

When healthy women eat a protein-rich yogurt snack in the afternoon instead of a chocolate bar, they feel less hungry later on, especially about an hour and a half after eating.
