Self-selected meal composition alters the relationship between same-day caloric intake and appetite scores in humans during a long-term ad-libitum feeding study

Cross-Sectional Study

Human

2023 Mar

When people ate a meal they chose themselves (not the study meal), they ate more calories that day—even though they didn’t feel hungrier or fuller than usual. This suggests protein affects how much we eat without changing how hungry we feel.
