Eating more protein makes you feel fuller for longer, so you’re less likely to snack or eat too much later.
See the scientific wording
Higher protein intake is associated with increased satiety compared to lower protein diets, potentially reducing hunger and spontaneous food intake.
Correlational — new studies may shift this
One low-scoring study links this claim to the outcome, but causation is not established.

Systematic Review With Meta-AnalysisMeta-analysis2004
This study found that eating more protein makes people feel fuller longer and less likely to snack or eat extra food later, which is exactly what the claim says.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
The pooled effect of protein intake on subjective satiety ratings across standardized meal tests and populations.
A meta-analysis of 20+ randomized crossover trials in adults (18–70) comparing isocaloric meals with 25–30% vs. 10–15% protein, measuring satiety via validated visual analog scales at 1, 2, 4, and 6 hours post-meal.
Causal effect of protein dose on acute satiety in controlled feeding conditions.
A double-blind, randomized crossover RCT of 30 overweight adults consuming three isocaloric breakfasts (10%, 20%, 30% protein) on separate days, measuring hunger/fullness via VAS and subsequent ad libitum lunch intake.
Long-term association between protein intake frequency and self-reported hunger or snacking behavior.
A 3-year cohort study of 3,000 adults tracking daily protein intake via 7-day food records and weekly self-reported hunger/satiety scores, adjusting for total calories, fiber, and sleep.
