Janet Polivy

University of Toronto Mississauga

Known for:Co-developer of the restraint theory of eating and the what-the-hell effect — how rigid dietary rules and cognitive reclassification of violations drive binge eating

Key findings

  1. 1985

    With C. Peter Herman, Polivy named and described the what-the-hell effect: a single transgression of a dietary rule triggers an all-or-nothing cognitive reframe that reclassifies the day as ruined, removing the motivation to moderate and licensing a full binge.

  2. 2002

    Polivy and Herman's review of the what-the-hell effect and the false-hope syndrome found that unrealistic dietary goals amplify the loop: the more extreme the initial rule, the more severe the all-or-nothing reclassification after any deviation and the harsher the resulting self-talk.
