This study developed a reliable method to measure satiety over time after a Western diet meal. The categorical comparison approach quantifies subjective feelings of fullness and hunger, providing insights into interoception.

Area of Science:

  • Nutrition Science
  • Human Physiology
  • Psychophysics

Background:

  • Dietary patterns significantly influence satiety and interoceptive awareness.
  • Quantifying subjective feelings of hunger and fullness is crucial for understanding eating behaviors.
  • Previous methods for satiety assessment lacked detailed temporal resolution.

Purpose of the Study:

  • To develop and validate a novel method for assessing the time course of satiety.
  • To evaluate subjective sensations of fullness and hunger following a standardized Western diet meal.
  • To characterize the temporal changes in interoception after meal consumption.

Main Methods:

  • An energy-controlled study involving 8 healthy subjects consuming a Western diet (45% fat, 40% carbohydrate, 15% protein).

  • A categorical comparison method using four sensation categories: very full, full, appetite, and hungry.
  • Subjects recorded sensations every 30 minutes for 4 hours post-meal over four 9-day test phases with long wash-out periods.
  • Mathematical transformation of subjective judgments into a numerical system to analyze the time course of satiety.

    • Main Results:

    • The categorical comparison method provided reliable and reproducible data on satiety.
    • The time course of satiety was successfully characterized, reflecting changes in interoception.
    • Individual satiety perception patterns were quantified over a 4-hour period post-meal.

    Conclusions:

    • The developed categorical comparison method offers a reliable approach to measure satiety over time.
    • This method effectively quantifies subjective interoceptive changes related to meal consumption.
    • Findings contribute to a better understanding of satiety regulation and dietary influences.
