Small packages trick some into eating more

Clearly, they are "tricked" into eating more.

"If you think buying junk food in small packages will help you eat less, look out — marketers know the truth.

Two new marketing studies found that some people tend to consume more calories when junk food portions and packages are smaller. For some, it's because they perceive small packages to be — get this — diet food."

For all, it is because they are idiots.
