When young people eat, their body releases more of the fullness hormone than older people do, which might help them feel satisfied faster.
Scientific Claim
Younger adults show a stronger postprandial increase in cholecystokinin (CCK) after a meal than older adults, regardless of frailty status, indicating age-related blunting of this satiety signal.
Original Statement
“Postprandial CCK concentrations were enhanced in young persons, whereas no frailty effect on the CCK curve was observed in the old subjects.”

Assessment Explanation
The abstract describes group differences but does not establish causation. The claim must avoid implying biological mechanisms or causality.
More Accurate Statement
“Younger adults show a stronger postprandial increase in cholecystokinin (CCK) after a meal than older adults, which is associated with age, regardless of frailty status.”
Evidence from Studies
Supporting (1)
Effect of age and frailty on ghrelin and cholecystokinin responses to a meal test.
Younger people’s bodies release more of a fullness hormone (CCK) after eating than older people’s bodies do, and this has to do with getting older—not how frail someone is.
