What the study found

Acute stress did not change gastric interoception overall, but it was linked to reduced fullness sensitivity in some participants. The effect depended on individual differences in emotion regulation difficulties and eating traits.

Why the authors say this matters

The authors suggest these findings may help identify a group at risk for interoceptive desensitization under stress. They conclude this could inform studies of interoception-focused interventions.

What the researchers tested

Ninety-four fasting participants completed a stress task and a control task in counterbalanced order across two laboratory sessions. Gastric interoceptive sensitivity was measured with the Magic Table, a novel method in which participants ate yogurt from a self-refilling bowl until satiation and fullness; 61 participants also completed the Two-step Water Load Test (a test of fullness based on drinking water) and a free-food consumption task for validation.

What worked and what didn't

Medium to strong correlations between Magic Table measures, the Water Load Test, and food intake supported the validity of the Magic Table. Stress showed no overall effect on gastric interoception, but cross-level interactions indicated reduced fullness sensitivity under stress among participants with high emotion regulation difficulties, restrained eating, and uncontrolled eating.

What to keep in mind

The abstract does not describe limitations beyond the study being based on laboratory tasks and self-reported eating traits. The findings are specific to the participants and measures used in this study.

Key points

  • Stress did not affect gastric interoception overall.
  • Under stress, participants with higher emotion regulation difficulties showed reduced fullness sensitivity.
  • Reduced fullness sensitivity under stress was also seen in participants with restrained eating and uncontrolled eating traits.
  • The Magic Table was supported by medium to strong correlations with the Water Load Test and food intake.
  • The study used 94 fasting participants, with 61 also completing validation tasks.
