McDonald's portions have super-sized since the fast food chain's first store opened in 1955. At that time, a customer could order only one size of fries off the menu, and the serving was about 2.4 ounces, according to Buzzfeed. That's .2 ounces less than a standard small fries offers today. But who's choosing small when you can get a lot more fries for just a little extra dough? Today's large serves up 5.9 ounces of fried potatoes -- and 510 calories to boot.

　　自1955年第一家麦当劳开业以来，麦当劳快餐的份量就已经翻了翻。根据Buzzfeed的说法，那时候顾客在菜单上能点到的薯条就只有一种大小，份量大约是2.4盎司，比今天标准小薯条的份量还要少0.2盎司。但如果只加一点点钱就可以多吃很多薯条，那谁还会选小的呢?今天的大薯条份量有5.9盎司，还含有510卡路里等着你去消耗。

　　We can't be so surprised, then, that Americans' waistlines have increased as their sodas, burgers and fries have been seriously beefed up. In the early 1960s, the average American man weighed 166.2 pounds. In 2010, he weighed 195.5 pounds, gaining nearly 30 pounds.

　　既然饮料、汉堡和薯条都实实在在地加了量，那美国人的腰围跟着增加也就没什么好奇怪的了。在20世纪60年代早期，美国人的平均体重是166.2磅。而2010年，平均值变195.5磅了，增重近30磅。

　　Other restaurants have expand their plates, too, of course -- according to the CDC, the average restaurant meal is now more than four times larger than it was in the 1950s.

　　当然，其他餐厅的饭菜也变得更大盘了——根据疾病预防控制中心的记录，今天普通餐厅的饭菜份量是20世纪50年代的4倍有余。
