From 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 · study

See the scientific wording

In adults undergoing long-term ad-libitum feeding with a high-protein protocol, subjective ratings of hunger and fullness remain unchanged on days following a self-selected meal with altered macronutrient composition.

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.

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

What you eat in one meal matters more for how many calories you eat that day than how hungry or full you feel.

How full or hungry people feel doesn’t explain why they eat more or less after choosing their own meal.

Eating a meal you choose yourself makes you eat more that day and a little less the next day — but then you go back to normal.

When people on a high-protein diet eat a meal they choose themselves, their total calories go up — but they don’t feel any different in hunger or fullness.

People on a high-protein diet usually pick one meal a week to eat whatever they want — and when they do, they eat more that day but don’t feel any hungrier or fuller than usual.

Even when people eat more or less than usual because they chose a different meal, they don’t feel hungrier or fuller than normal.
