Adherence

Acute psychological stress increases energy intake of sweet and total snack foods in the absence of hunger, with the magnitude of intake strongly correlated with the degree of state anxiety induced by the stressor.

If you find yourself snacking when you are not hungry after a stressful event, recognize this as a stress response, not hunger. The more anxious you feel, the more you are likely to eat, especially sweet foods. To counter this, focus on stress-reduction techniques (like the control task used in the study) rather than willpower alone, as the drive is linked to the anxiety level itself.
