We've all been guilty of it.
You've been busy all day, or haven't had a chance to plan dinner.
The quick and simple solution: fast food.
Although most of us know it is not the healthiest of choices, you may not know it can cause taxing effects on your mind as well.
A new study suggests fast food can make us impatient, crave instant gratification, and make us less frugal.
Researchers conducted three small experiments on college undergraduates.
One experiment had students watch a computer screen while fast food logos were flashed too quickly for the mind to register.
Their reading speed was measured before and after seeing the logos.
It was significantly faster afterward.
In another study, students who recalled eating at a fast-food restaurant subsequently preferred time-saving products, such as two-in-one shampoo-over regular products.
A final experiment found people exposed to fast food logos preferred to accept a small amount of money immediately, rather than a much larger amount a week later.
