Bigger serving sizes came into vogue during the 1980s, and waistlines in the Western world have continued to parallel the growth of portion sizes ever since. Even portion-controlled snack packs can lead to overeating: if one is okay, many people seem to assume that it’s alright to eat more.
Researchers from Wageningen University in the Netherlands and Cornell University in New York teamed up to see if smaller snacks could decrease hunger and cravings as effectively as larger snacks. They chose three of the most commonly craved foods—potato chips, apple pie, and chocolate—gave them to 104 college students (average age 20 years) in two different serving sizes and recorded the people’s feelings about how satisfying they found the snack.The large-portion snack contained 1,370 calories from 100 grams of chocolate chips, 200 grams of apple pie, and 80 grams of potato chips. The small portion contained 195 calories from 10 grams of chocolate chips, 40 grams of apple pie, and 10 grams of potato chips.
Hunger and cravings were measured just before the snack, immediately after the snack, and again 15 minutes later.
"This suggests that compared to providing larger portions, smaller portions of commonly craved foods are capable of providing similar fulfillment of desire," concluded the authors.
Although the new study was small and only included a single portion size trial, it is in line with previously published studies that show the effect of portion size on calories consumed. It also adds the hopeful new finding that smaller snacks might satisfy cravings and hunger as well as larger ones. Future studies are needed to confirm these findings.
