Memory of big meal could make you feel less hungry and help lose weight.
Researchers from the University of Bristol found that people who think they have eaten more - but have actually eaten an average-sized or smaller portion - are less likely to experience hunger pangs hours later.
The discovery may help those struggling to lose weight.
Jeffrey Brunstorm and colleagues from the University showed volunteers either a small or large portion of soup just before lunch, and then manipulated the amount of soup they actually consumed by means of a covert pump that could refill or empty a soup bowl without the eater noticing.
Immediately after they ate, the level of hunger reported by the volunteers was proportionate to the amount of food they had eaten, not the amount they had seen just before eating.
However, 2 to 3 hours after lunch, volunteers who had been shown a larger portion of soup reported significantly less hunger than those who had seen the smaller portion. Twenty four hours later, more of these volunteers who had seen the bigger portions believed that the portion of soup they had consumed would satiate their hunger.
The results demonstrate the independent contribution of memory processes to feelings of satiety after a meal, the researchers said.
"Opportunities exist to capitalize on this finding to reduce energy intake in humans," they stated.
Brunstrom added, "This study is exciting because it exposes a role for cognition in the control of hunger - appetite isn't governed solely by the physical size and composition of the meals we consume."
The study was published in the open access journal PLOS ONE. ( ANI )
