Researchers had 120 women drink either a thick 270-calorie smoothie or a thin 75-calorie smoothie while distracted by either an easy or a difficult computer task. Then they were offered potato chips and similar snacks.

The women ate about half as many chips—and reported feeling more full—after drinking the higher-calorie smoothie than after drinking the lower-calorie smoothie...but only after doing the easy task. After the harder, more-distracting task, the women ate as many chips and felt equally full, regardless of whether they had polished off a higher-calorie or lower-calorie smoothie.

What to do

Keep in mind that eating may not curb your appetite or make you feel as full if you were distracted while you ate.
