Unite 1. Be realistic.

第一单元 要务实一点

One pound of fat equals 3，500 calories. To lose one pound，you need to consume 3，500 fewer calories.“That’s a lot!”we can hear you protesting. But you don’t have to do it all in one day. A realistic goal is to lose a pound a week by cutting back just 500 calories a day.One less burger and fries，fewer cookies.low-fat salad dressing，and you’re just about there for the week.Do it again next week and the week after, and you’re well on your way.

一磅的脂肪相当于三千五百卡。要减去一磅的体重，你需要消耗至少三千五百卡。“那样很多耶!”我们可以听到你的抗议。但你不必在一大之中都做到。一个比较务实的目标就是，一星期减一磅.这样一天只要减五百卡就可以了。你只要少吃一个汉保和一份薯条，少吃一点饼干，改吃低脂沙拉酱.这样一个早期下来.你差不多也减了三千五百卡。隔周再来一次.接下去的一星期也一样，这样一来你的节食计划便上轨道了。

You may want to lose more than a pound a week.But studies suggest that if you cut calorie consumption too drastically.your body counteracts¹ the effect of dieting. In other words,don’t try to cut out more than 500 calories from your daily diet.

你可能会想一星期减掉一磅以上的体重。但研究结果显示，如果你的卡路里消耗量太过剧烈，你的身体会抵消掉节食的效果。换句话说，不要想从每天的饮食中减掉超过五百卡的热量。
