Evidence summary

Evidence is strong that acute protein intake can improve satiety. Long-term weight-loss effects are more variable and depend on the overall eating pattern.

Strong evidenceSystematic review and meta-analysis

Kohanmoo A, Faghih S, Akhlaghi M · Physiology & Behavior · 2020

Acute protein intake generally reduced appetite and changed several appetite-related hormones, while long-term findings were less conclusive.

Why it matters: Supports protein-forward meals for satiety while avoiding exaggerated long-term promises.
