People Think Meals Taste Better If They Are Expensive

It is said that there’s no such thing as a free lunch, but even if you manage to bag a bargain meal, it will not taste as good as a more expensive meal, according to scientists.

The price of the food was set by the 【3】 at either $4 or $8 for the all-you-can-eat meal. Customers were asked to 【4】 how good the food tasted, the quality of the restaurant and to leave their names.

Interestingly those that paid for the $4 buffet said they felt guiltier about loading up their plates and felt that they 【6】.

In a(n) 【10】 study, scientists from the university showed that people who eat in dim lighting consume 175 less calories (卡路里) than people who eat in brightly lit areas.
