Sometimes the only cue people get to stop eating is an awful feeling, telling you your stomach is unforgivingly angry and is threatening to bloat for hours -- but fear not, your friendly neighborhood edible stop signs are sure to slow you down and save the day.

Cornell University Food and Brand Lab researchers experiment with red-dyed Lays Stackables potato chips dispersed at regular intervals to act as subconscious stop signs. The intervals between chips are meant to represent a single serving size. Results of the study done using college students, who are notoriously guilty of late-night snacking, show that people in the 'edible stop sign' group were better able to judge how many chips they had eaten (within one chip!) versus the group with no colored cues. They also ate 50% less chips than the group without visual markers.

In a society where obesity is becoming a bigger and bigger problem -- literally -- these edible stop signs have the potential to put the brakes on this health epidemic.
