Energy density, palatability, and satiety: implications for weight control.

High energy density tends to be associated with high palatability, and vice versa. As a rule, energy-dense foods are palatable but not satiating, whereas foods with low energy density are more satiating but less palatable. Low-energy-density foods are typically those that contain the most water and the least fat. Reducing energy density while maintaining palatability is a continuing challenge to the food industry.
