This study only looked at what happened after one snack, so we don’t know if eating yogurt every afternoon helps with weight loss over time.
Scientific Claim
In healthy women aged 27 ± 2 years with normal BMI (23.4 ± 0.7 kg/m²), the effects of a high-protein yogurt snack on appetite control and subsequent intake are acute and limited to a single afternoon, with no evidence provided for long-term weight management benefits.
Original Statement
“This was an acute trial over the course of a single day. Longer-term randomized controlled trials are also critical in establishing whether the daily consumption of a less energy dense, high-protein snack improves body weight management.”
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
definitive
Can make definitive causal claims
Assessment Explanation
The authors themselves acknowledge the limitation, and the study design (single-day RCT) cannot support long-term claims. This is an accurate reflection of evidence boundaries.

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 and eat less at dinner that same day—but it didn’t look at whether this helps with weight loss over time, which matches the claim perfectly.
