Self-reported overeating and attributions for food intake

Area of Science:

• Behavioral Science
• Food Psychology
• Eating Behavior Research

Background:

• Understanding the psychological factors influencing eating behavior is crucial for public health.
• Attribution theory provides a framework for examining how individuals explain their actions, including food intake.

Purpose of the Study:

• To investigate if attributions for eating behavior vary based on self-perceived consumption relative to normal intake.
• To explore the influence of portion size and self-evaluation of intake on attributions to internal (hunger) and external (food availability) cues.

Main Methods:

• Participants were served either small or large portions of pasta.
• Post-meal, participants categorized their intake as 'ate less,' 'ate about the same,' or 'ate more' than usual.
• Attributions for food intake were assessed concerning hunger and the amount of food served.

Main Results:

• Larger portions led to greater consumption, but this effect was consistent across intake-evaluation groups.
• Hunger influenced intake for all participants.
• Only participants who believed they 'ate more' attributed their intake to the amount of food available.

Conclusions:

• Individuals are more likely to cite external factors (e.g., portion size) for their eating behavior when they perceive themselves as having overeaten.
• This suggests a self-serving bias in attributing food intake, where external cues are invoked to justify perceived overconsumption.
