不知道你是不是有過這樣的體驗？到了吃飯時間，跟著人流走到食堂，隨便要兩個菜，吃完，然后回到辦公室。如果有人問了吃了什么，你有可能隱約記得；問你味道怎么樣，可能你壓根都沒有注意那菜是有味道的。這大概就是很多人都說過的“審美疲勞”，當然，這里應該是“味覺疲勞”。而我們這樣的進餐狀態大概就只能叫做auto-eating了。

Women can munch their way into a bigger dress size in weeks by "auto-eating" the calorie equivalent of a Big Mac a day....
如果每天機械地吃進去相當于一個巨無霸漢堡那么多的熱量，女人們的身材可以在幾周內就加大一號。

Nutritionist Mary Strugar coined the term auto-eating, which presumably means eating without the feeling of actual hunger and perhaps even without being fully aware of consuming the calories.
Auto-eating（機械進食）這個詞是由營養學家瑪麗?斯圖佳首先提出來的，指毫無饑餓感時的進食，而且進食的時候根本沒有意識到同時有多少熱量被攝入。

Auto-eating may also refer to the kind of eating you do without thinking because the food you're chewing on is so bland, so meek, your taste buds become indifferent to what's passing over them.
另外，機械進食也可以指麻木的進食狀態，可能因為口中的食物太清淡、太無味，致使味覺系統對食物沒有任何反應，只是在機械傳送。

According to recent research, it may be something like upset or boredom and having nothing better to do that makes many women go into the “auto-eating” mode.
據最新的研究顯示，心情沮喪或無聊、又找不到別的事情做可能是很多女性“機械進食”的原因。
