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.
Scientific Claim
In healthy women aged 27 ± 2 years with normal BMI (23.4 ± 0.7 kg/m²), the satiety effects of a high-protein yogurt snack are not replicated in all prior studies, indicating variability in outcomes based on snack type, energy content, and participant characteristics.
Original Statement
“The inconsistent findings of eating initiation and dinner intake between the previous studies and the current study may be attributed to the differences in snack type, macronutrient content, energy content, and energy density.”

Effects of high-protein vs. high- fat snacks on appetite control, satiety, and eating initiation in healthy women
This study found that a high-protein yogurt snack made women feel less hungry and wait longer before eating again compared to fatty snacks like chocolate or crackers — but not always in every way, showing that what you snack on really matters.
