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

Scientific Claim

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.

Original Statement

“On the SSM day, the mean ± SD daily caloric intake increased by 262 ± 332 kcal compared to the previous study days (P < 0.001), with no changes in subjective appetite scores. [...] The following day there was a slight but significant reduction in intake [...] with no change in appetite scores.”

Even when people ate a meal with different protein levels than usual, they didn’t feel hungrier or fuller the next day — their hunger feelings stayed the same, even though they ate more or less.

Similar Assertions

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

89%

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

89%

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.

88%

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.

87%

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.
