Less is more: Mindfulness, portion size, and candy eating pleasure

•We examined eating pleasure and guilt as function of candy (Reese’s Peanut Butter Cups) portion size and mindful eating.•When eaten normally, pleasure did not differ between a small vs. large portion of the candy.•When eaten mindfully, pleasure was higher for a small vs. large portion of the candy.•When eaten normally, but not when eaten mindfully, guilt was higher for a large vs. small portion of the candy.•An awareness of these effects could encourage people to reduce the portion sizes of the candy they consume.
