THE FACTS Late November marks the start of the gluttonous holiday season. But a simple step might help keep food intake in check: a glass of water before meals.
十一月下旬是饕餮假期的开始。但是，一个简单的步骤或许有助于控制食量：饭前一杯水。
Dieters have been encouraged to employ this trick for ages, with the reasoning quite simple: the water fills the stomach, thus reducing hunger. But only in recent years have studies borne this out.
在节食者中间有这样一个小妙招流行了数年，他们的原理很简单：把胃填满水，从而减少饥饿感。但是，直到近几年才有支持这一观点的研究。
In the most recent, a randomized trial published in the journal Obesity in February, scientists at Virginia Tech followed a group of overweight subjects age 55 and up on low-calorie diets for about three months. Half the people were told to drink two cups of water before every meal. At the end of the study, the water group had lost an average of 15.5 pounds, compared with 11 pounds in the other group.
最近，《肥胖》杂志二月号发布了一项随机试验，弗吉尼亚理工大学的科学家对一群55岁的超重受试者进行了实验，他们在约三个月的时间里进食低热量饮食。一半的人被告知每顿饭前喝两杯水。研究结束时，喝水的一组平均减了15.5磅，而另一组只减了11磅。

A 2008 study showed a similar effect, finding a 13 percent reduction in calorie intake in overweight subjects who consumed water before breakfast. But a third study, this one in 2007, had a peculiar finding: drinking water 30 minutes before a meal reduced calorie intake and feelings of hunger in older adults, but had little effect on subjects under 35. It’s not clear why, but the researchers pointed out that because older adults are at increased risk of being overweight and obese, further studies should determine whether this is effective for the aging population.
2008年的一项研究也有相似的结果，早饭前喝水的超重受试者热量摄取减少了13个百分点。但另一项2007年的研究却有一个奇特的发现：老年人在饭前30分钟喝水，热量摄入会减少，他们会有饥饿感；但对于35岁以下的受试者却几乎没什么影响。目前还不清楚是什么原因，但研究人员指出，由于老年人超重和肥胖的风险增加，所以应进一步研究确定这是否对老年人群有效。
Studies show the average person gains about a pound between Thanksgiving and January. Most adults gain one to two pounds a year over a lifetime, so staving off the holiday pound can go a long way. Drinking water before a meal can reduce calorie intake, though the effect seems most prominent in older people.
研究显示，普通人在感恩节和一月份期间体重会增加约一磅。大多数成年人一生中，一年会增加一到两磅，所以避开在假期长肉将会对保持体重大有帮助。饭前喝水可以减少热量的摄取，而效果最突出的似乎是老年人。
