Why We Unknowingly Overeat

The Influence of Incidental Affect on Consumers' Food Intake

How do affective states influence food intake and what role does nutritional information and the nature of the product play on this effect?   The present research examines how different affective states influence consumption, and how nutritional information plays into this relationship. Implications for food companies, policy makers, health professionals and consumers are presented and discussed by the authors.

Can “Low Fat” Nutrition Labels Lead to Obesity?

In the current obesity epidemic, the way that "low-fat" nutritional labels influence food consumption is of great concern, particularly for regulatory agencies. Through the three studies presented in this paper the authors developed and tested a framework that contends that "low fat" labeling increases food intake by 1) increasing perceptions of the appropriate serving size and 2) decreasing consumption guilt.

Studies at “Weight-loss Camps” (and with veteran bartenders) show that visual illusions unknowingly cause people to pour 32-43% more in to short wide glasses than tall narrow ones.

Interactions Between Forms of Fat Consumption and Restaurant Bread Consumption

Hidden cameras at Italian restaurants show that people who put olive oil on a piece of bread will eat more fat and calories than if they instead used butter. The good news . . . they eat fewer pieces of bread.

Bad Popcorn In Big Buckets: Portion Size Can Influence Intake As Much As Taste

It is often believed that people overeat the foods they like. We investigate whether environmental cues such as packaging and container size are so powerful that they can increase our intake of foods that are less palatable. If so, there are important implications for improving the consumption of healthy (but less preferred) foods.

Why Visual Cues of Portion Size May Influence Intake

Using self-refilling soup bowls, this study examines whether visual cues related to portion size can influence intake volume without altering either estimated intake or satiation.
