Summary: van Kleef et al. (2013)

Obesity and increased weight gain is of considerable interest worldwide, in part due to an increase in portion size of energy-rich foods. van Kleef et al. (2013) questioned whether smaller snack sizes could be as effective at decreasing hunger cravings as larger snack sizes. They presented 104 participants with one of three common snack foods (chocolate, apple pie, potato chips), as either a larger or smaller portion. They found that small portions appeared to satisfy the participants hunger and craving ratings in a similar manner to larger portions, however, the overall caloric intake was less (by about 103 calories). van Kleef et al. (2013) suggest that although consuming less, a small snack can result in equal satisfaction after consumption.
