The memory of a big meal 'could make people less hungry'

7 November 2012

People who remember eating a big meal are less hungry hours after a meal than those who do not believe they ate that much, according to a new study.

For a paper published in the journal PLOS ONE, volunteers were shown either a small or large portion of soup just before lunch.

The researchers then manipulated the amount of soup participants actually consumed using a covert pump able to refill or empty a soup bowl without the eater noticing.

Immediately after eating, the level of hunger volunteers reported was proportionate to the amount of food they had consumed rather than the amount they had seen before eating.

However, two to three hours after lunch, participants who had been shown a larger portion of soup reported significantly less hunger than those who had seen the smaller portion.

Furthermore, after 24 hours, more of the volunteers who had seen the bigger portions believed the amount of soup they had consumed was satisfactory to satiate hunger.
