Meals with enough or lots of protein make two key hunger hormones (CCK and ghrelin) stay active longer in both lean and obese men, which might help them feel full longer.
Scientific Claim
High-protein and adequate-protein meals are associated with sustained cholecystokinin (CCK) and ghrelin responses in both lean and obese men, suggesting these hormones may play a role in prolonged satiety.
Original Statement
“There were no major differences in hormone responses to the meals among subject groups, but the CCK and ghrelin responses to HP and AP were sustained in both groups.”

Assessment Explanation
Based on abstract only - full methodology not available to verify. The term 'sustained' describes observed patterns, but causation or mechanism cannot be confirmed without full methods.
Evidence from Studies
Supporting (1)
The study found that meals with enough protein (not too much, not too little) made people feel fuller longer because they triggered lasting changes in two key hunger hormones, CCK and ghrelin, in both thin and overweight men.
