The volume of food consumed may affect satiety in several ways. First, a larger volume of food can affect the perception of how much food is being consumed. Next, more time is required to consume foods that are larger in volume than those that are smaller in volume. This effect could be substantial in that it allows the necessary time for important feedback mechanisms associated with satiety to reach the appetite control centers in the brain.
Perhaps the biggest impact of increased food volume as it leads to reduced caloric intake relates to its effect on producing distension of the stomach. In fact, the air in Dr. Rolls&aposs milkshakes (see "The Satiety Effect of Air," page 67) produced greater distension of the stomach and therefore influenced subjective responses related to hunger and appetite. In both animal and human studies, the degree of gastric distension is known to affect food intake, particularly by effecting the feeling that you have had enough.

In addition to creating a sense of fullness, the volume of a food influences satiety by slowing down gastric (stomach) emptying. In essence, the longer the food stays in the stomach, the stronger and longer lasting is the satiety feedback to the appetite control centers of the brain.
