零起点美语-Be realistic.

Be realistic.

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.
You may want to lose more than a pound a week. But studies suggest that if you cut calorie consumption too drastically, your body counteracts the effect of dieting. In other words, don’t try to cut out more than 500 calories from your daily diet.
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。但你不必在一天之中都做到。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。你只要少吃一个汉堡和一份薯条，少吃一点饼干，改吃低脂沙拉酱，这样一个星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。
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。
