Turning the lights out or wearing a blindfold while eating could be a quick way to lose weight, according to scientists. 科学家称，关上灯或是蒙上眼睛吃东西，不失为一条减肥的捷径。 The simple trick works because it stops diners eating for pleasure rather than for calories. It also triggers a part of the brain that is worried that unseen food may be rotten without visual clues to show it is fresh. 这一方法之所以有效，是因为它降低了美食的诱惑力，同时让大脑无从判断食物新鲜与否，进而影响食欲。 An experiment by the University of Konstanz, in Germany, found that people who were blindfolded consumed nine per cent fewer calories before they felt full, compared to those who could see. 德国康斯坦茨大学的一项试验发现，对比能够看着食物进餐的人，蒙住眼睛进食的受试者要少摄入9%卡路里。 |
