很多人说吃自助餐都是“扶墙进，扶墙出”，进去的时候快饿死了，出来的时候快撑死了。反正，进了自助餐厅，不玩命吃好像就不正常似的。这股子猛吃的动力因此也就得名“自助餐动力”（buffet momentum）。
Buffet momentum is the lack of self-restraint one experiences after having started eating at a buffet. this phenomenon causes a person to consume above and beyond what comprises a regularly sized meal. This feeling usually occurs in the first fifteen minutes of the buffet and is further perpetuated by:
Buffet momentum指在自助餐厅开吃以后就难以自制，不停要吃东西的情形，即“自助餐动力”。这种动力会让人吃下远远超出常规饭量的食物。“自助餐动力”一般出现在自助餐开始的前15分钟，然后会通过以下的方式延续：
a) remembering something delicious that you saw earlier and didn't have room on your plate for
记起来之前看到的某个好吃的，当时盘子太满没装下
b) wanting more of something you just tried
刚尝过的东西，还想再吃
c) the desire to make the price you paid worthwhile
想把付的钱都吃回来
d) the need to illustrate to your friends that your stomach is indeed a bottomless pit.
想证明给自己的朋友看，你的胃的确是个无底洞。
For example:
"Wow, I just consumed three plates of food. Maybe we should wait a while before hitting up the dessert table."
哇！我刚吃完了三盘子，我们过一会儿再吃甜点吧。
"I disagree. In about 10 minutes my stomach is going to realize that it's full, so I think I'll just make use of the buffet momentum that I've developed and get dessert right now."
不行。10分钟以后，我的胃就该意识到自己已经满了，所以，我认为有必要利用现在的自助餐动力把甜点给吃了。
