改善健康也许很简单:每天少吃300卡

这项新研究由美国国家卫生研究院（National Institutes of Health，简称NIH）出资并发表在本月的《柳叶刀糖尿病与内分泌学》(Lancet Diabetes & Endocrinology)期刊上，其中研究人员对一群年龄介乎21岁至50岁的143名健康男性和女性进行了观察。他们按照指示，进行了为期两年的卡路里摄入限制。他们可以食用自己想要的食物，条件是减少摄入食物总量，目标是使他们摄入的热量减少25%。

Many did not achieve that goal. On average, the dieters managed to slash about 12 percent of their total calories, or roughly 300 calories a day, the amount in a large bagel, a few chocolate chip cookies or a small Starbucks Mocha Frappuccino. But the group saw many of their cardiovascular and metabolic health markers improve, even though they were already in the normal range.

很多人没达到这一目标。平均而言，节食者得以将总热量削减了约12%，大致相当于每天300卡路里，这是一个大贝果、几块巧克力曲奇或一小杯星巴克摩卡星冰乐的热量。但这组人中，很多人的心血管和新陈代谢健康指标都得到了改善，尽管他们原本已在正常范围内。

They lost weight and body fat. Their cholesterol levels improved, their blood pressure fell slightly, and they had better blood sugar control and less inflammation. At the same time, a control group of 75 healthy people who did not practice caloric restriction saw no improvements in any of these markers.
