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.
Scientific Claim
In healthy women aged 27 ± 2 years with normal BMI (23.4 ± 0.7 kg/m²), a 160-kcal high-protein yogurt snack delays the voluntary initiation of dinner by approximately 30 minutes compared to a 160-kcal high-fat chocolate snack (164 ± 7 min vs. 137 ± 9 min, p < 0.01), indicating enhanced satiety duration.
Original Statement
“The consumption of the yogurt snack delayed dinner eating initiation... by approximately 30 min compared to the chocolate snack (yogurt: 164 ± 7 min post-snack vs. chocolate: 137 ± 9 min post-snack, p < 0.01)”

Effects of high-protein vs. high- fat snacks on appetite control, satiety, and eating initiation in healthy women
The study found that eating a high-protein yogurt snack in the afternoon made women wait about 30 minutes longer before feeling hungry enough to eat dinner, compared to eating a chocolate snack with the same calories — meaning the yogurt kept them fuller longer.
