为什么看电视时总想吃东西？尤其是看美食节目时，总是感觉“越看越饿”。难道看电视真的会刺激食欲吗？
Sitting down in front of the television with a meal or snack after a long day is a very popular recreational pastime. And thanks to streaming services that play every episode of a television series automatically, some viewers aren't even burning the few calories it might take to reach for the remote.
在漫长的一天结束时坐在电视机前吃东西是很受欢迎的休闲方式。现如今流媒体平台可以自动播放下一集电视剧，观众甚至连起身去拿遥控器的那点运动量都省了。
But is it sloth1 that keeps us chewing, or something else? Is it possible the experience of watching TV can stimulate2 our appetite?
但是为什么我们看电视时会不停嘴地吃？是因为懒惰，还是别的什么原因？看电视是否会刺激食欲呢？
According to the Cleveland Clinic, television isn't so much an appetite stimulant3 as it is an appetite distraction4. When we watch TV, we're engaged in the program, which means we're paying less attention to the neurological and gastronomical5 cues that tell us we're getting full. Instead of taking note of how we're eating, we're engaged in somewhat passive consumption.
