Why are restaurants almost always dark? According to a new study out of Germany, it could be to get you to eat more.

Benjamin Scheibehenne, Ph.D says paying more attention to your food helps you to eat less. He says that by eating in the dark, or low-lit areas, we receive less information about how much food we are actually eating. How did he conclude this?

Well, Scheibehenne served people oversized meals in complete darkness. He found those eating in the dark ate 36% more food than those given regular portions. When he moved those same people to a place that was well-lit, they consumed less food.

So, conclusions show the more you are able to pay attention and actually look at your food, the less you will consume.

If you're one on a diet, next time you go out to eat, ask for the table with the spotlight.
