just eat a potato chip earth takes some serious self-control, so that researchers from Cornell Food and Brand Lab at the University came up with a new way to keep from overindulging snackers :. edible insertion "stop signs" in packaged stacks
The researchers conducted two studies in a total of 98 undergraduate students: both, the students received Lays tubes stacked nosh chips all watching video clips in class. In the first study, the researchers inserted dyed red chips at regular intervals in the stack - or to mark seven chip (one serving) or every 14 chips (two servings). A control group received a regular unmarked pile of chips. In the second study, the red chips were inserted every five to 10 tokens.

None of the participants said that the red chips were for, but in both studies, students who got the tubes with stop signs subconscious ate less -. about 50% less than those of control groups
In the first study with indicators of seven and 14-chip, students ate on average 20 and 24 chips, respectively, compared to 45 tokens consumed by the control group. In the second study, those with the five chip and 10-chip marker ate chips 14 and 16, respectively, compared to the average of 35 tokens consumed by the control group.
The students snacking smart pipes with stop signs also have estimated more precisely the number of chips they had eaten. They were able to guess their total consumption in a single chip, while students in underestimated their power control groups by about 13 chips.
People generally eat what is put in front of them if it is acceptable, the authors write. "When you eat something small like chips, the process begins to become automatic and you get into a cycle," says researcher Paul Rozin study from the University of Pennsylvania.

This stupid habit of eating helps explain why some people go to sea while nibbling. Other reasons the study notes: people are not good at self-monitoring how much they eat they eat or what they believe - wrongly - is an appropriate part of
."By inserting visual markers in a food snack pack, we may be helping them to monitor how much they eat and stop their eating semi-automatic habits," lead researcher Brian Wansink, director of Cornell Food and Brand Lab and author of Mindless Eating: Why We Eat More than We Think said in a statement
.Overall, the researchers say, the edible stop signs reduces intake by about 250 calories snackers.

"Generally, people tend to eat a" "something," said Rozin. "People will eat a piece of fruit, a sandwich. Using markers with food, you can specify :. '. This is a" The authors call for further research on what other foods could be easily segmented to help people consume less
They conclude in the document:
the effect demonstrated and replicated in these studies stands as perhaps the greatest possible steps to reduce food consumption in literature ... [A] manipulation of the sort we used could lead to a weight loss of more than one book a year, much of the uS annual weight gains in the past years.
