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.
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 (14 g protein, 0 g fat) in the afternoon reduces afternoon hunger more than a 160-kcal high-fat chocolate snack (2 g protein, 9 g fat), with a statistically significant difference in net incremental hunger area under the curve (p < 0.01) and lower hunger at 90 minutes post-snack (33 ± 5 mm vs. 50 ± 5 mm, p < 0.01).
Original Statement
“The consumption of the yogurt snack led to greater reductions in afternoon hunger AUC compared to the chocolate snack (p < 0.01)... the yogurt snack led to lower hunger at 90 min post-snack (33 ± 5 mm*min) compared to the chocolate (50 ± 5 mm*min, 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 feel less hungry than eating a chocolate snack with the same calories, and this difference was clear and meaningful.
