双语新闻：羡慕！为什么有些人怎么吃都不胖？

每个人身边都会有这样一个人——吃的比看起来能吃的多，喝下超过他份额的啤酒，狼吞虎咽下一整块意大利腊肠披萨，在抓一个冰淇淋，第二天早上在吃一个甜甜圈，然后体重一磅都不会增加。Everyone knows that guy -- the one who can chug more than his fair share of beer, scarf down an entire pepperoni pizza, grab an ice cream, and make a donut run the next morning, all without gaining a pound.
