How much chocolate would you need to eat
to be satisfied?
Less
than half as much as you think, according to this recently published Cornell
University snacking study. Using chocolate chips, apple pie, and potato chips,
researchers Ellen van Kleef, Mitsuru Shimizu, and Brian Wansink designed a
study to determine if people who were given smaller portions of snack foods
would feel hungrier or satisfied fifteen minutes after eating.
Participants were given either a small
portion (x) or a 5-10x portion
Two
groups with different portion sizes were tested. The larger portion size group
was given 100g of chocolate, 200g of apple pie, and 80g of potato chips, all
slightly larger than the recommended portion sizes. This equaled 1370 calories
in snack foods. The other group was given 10g, 40g, and 10g of these same foods
respectively, for a total of 195 calories. The two groups were given as much
time to eat as needed, and were asked to fill out surveys to rate the liking,
familiarity, and boredom with the food. They were also asked to rate their
hunger and craving before the food was presented and fifteen minutes after the
taste tests ended.
'Just a Bite' Will Satisfy
The
results remarkably showed that smaller portion sizes are capable of providing
similar feelings of satisfaction as larger ones. Those given larger portions consumed 77% more
food, amounting to 103 calories more, but they did not feel any appetite
enhancing or stronger feelings of satiety than the group with the smaller
portions.
Overall
these findings reflect the importance of portion size. While larger portions
result in increased food intake, smaller portions may make you feel equally
satisfied. The smaller portions can lead to a decline in hunger and desire that
would help people limit their food intake.
So,
next time you are craving a snack food, remember that you can feel similarly
satisfied with one handful as you would with two!
