A food portion cut into multiple, bite-sized pieces looks larger and elicits greater satiation than the same portion presented as a single, large piece, the team reported at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB).

No matter whether the two portions of food have the same calorific value.

A sample of 301 college students was given a bagel uncut or cut into quarters.

Twenty minutes after the bagel was consumed, subjects were told that they could eat as much or as little from a complimentary lunch. Any leftover bagel and test meal was then recorded.
