  • Title: The effect of portion size on food intake is robust to brief education and mindfulness exercises.
    Author: Cavanagh K, Vartanian LR, Herman CP, Polivy J.
    Journal: J Health Psychol; 2014 Jun; 19(6):730-9. PubMed ID: 23471762.
    Abstract:
    We examined whether a brief education and a brief mindfulness exercise would reduce the effect of portion size on food intake. Participants were randomly assigned to one of the three information conditions (education, mindfulness, or control) and then received a small or large portion of pasta for lunch. Neither education nor mindfulness was effective in reducing the effect of portion size: Overall, participants served a large portion consumed 34 percent more pasta than did those served a small portion. Participants in the mindfulness condition tended to eat less overall than participants did in the two other conditions, but this trend was not significant.
