  • Title: Life is uncertain, eat dessert first: Uncertainty causes controlled and unemotional eaters to consume more sweets.
    Author: Core TJ, Price MM, Alquist JL, Baumeister RF, Tice DM.
    Journal: Appetite; 2018 Dec 01; 131():68-72. PubMed ID: 30195822.
    Abstract:
    Sometimes even dieters with the best self-control overindulge. Uncertain situations may undermine the self-control of even well-controlled eaters. This study was designed to test the hypothesis that uncertainty increases unhealthy snacking. Participants were either told that they would be giving a speech, that they would be listening to a speech, or that they would find out later whether they were to give a speech or not. Among participants who typically reported good control over their eating or scored low on emotional eating, participants who were uncertain about whether they would be giving a speech ate more candy than participants who expected to not have to give a speech and even those who expected to have to give a speech. Participants who reported poor control over their eating or scored high on emotional eating did not eat significantly more when uncertain. These findings suggest that, for people who are typically able to control their eating, uncertainty increases snacking more than certainty of a negative outcome.
